In a setback for environmental protection efforts, recent UN talks failed to produce a concrete plan for addressing worldwide drought concerns. 



The extended discussions highlighted growing rifts between developed and developing nations on how to tackle the drought crisis.



At the United Nations Convention to Combat Desertification (UNCCD) COP16 meeting in Riyadh, delegates from 196 countries and the European Union worked through the night, pushing the talks a day beyond schedule. 



Ibrahim Thiaw, UNCCD Executive Secretary, had expressed high hopes at the start, stating that the world expected negotiators "to adopt a bold decision that can help turn the tide on the most pervasive and the most disruptive environmental disaster: drought."



However, as dawn approached after the night's efforts, Thiaw acknowledged that "parties need more time to agree on the best way forward."



<h2 class="wp-block-heading" id="h-a-pattern-of-failed-environmental-negotiations">A pattern of failed environmental negotiations</h2>



This latest setback follows several recent disappointments that have arisen in global environmental talks, including unsuccessful biodiversity discussions in Colombia and failed <a href="https://www.earth.com/news/how-can-we-combat-the-escalating-plastic-crisis/" target="_blank" rel="noreferrer noopener">plastic pollution</a> negotiations in South Korea.



Tom Mitchell from the <a href="https://www.iied.org/" target="_blank" rel="noreferrer noopener">International Institute for Environment and Development</a> noted that these outcomes have "highlighted the challenges facing global negotiations."



"More than ever, the fractured geopolitical landscape is proving to be a stumbling block to the COP process and some voices are being squeezed out," he added. 



<h2 class="wp-block-heading" id="h-the-real-cost-of-drought-inaction">The real cost of drought inaction</h2>



The stakes couldn't be higher. Droughts, already among the most devastating <a href="https://www.earth.com/news/natural-disasters-are-on-the-rise-but-hazard-plans-are-inadequate/" target="_blank" rel="noreferrer noopener">natural disasters</a>, are expected to intensify due to climate change - threatening both ecosystems and human livelihoods.



According to UN reports, drought-related economic losses currently exceed $300 billion annually, a figure that is likely to climb as water becomes more scarce.



Beyond financial tolls, the social and humanitarian impacts are staggering - droughts exacerbate <a href="https://www.earth.com/news/late-rainy-season-signals-upcoming-food-insecurity/" target="_blank" rel="noreferrer noopener">food insecurity</a>, force mass migrations, and heighten conflicts over dwindling resources.



<h2 class="wp-block-heading" id="h-the-growing-drought-crisis">The growing drought crisis</h2>



Projections for the future are even grimmer. By 2050, up to three-quarters of the global population could face drought conditions, placing unprecedented pressure on agriculture, water management systems, and urban planning. 



Regions already vulnerable will bear the brunt, but no part of the world will remain untouched. 



Rising temperatures, erratic rainfall patterns, and shrinking freshwater supplies are converging to create a perfect storm of challenges that require immediate and coordinated global action.



If no bold measures are taken, the ripple effects could jeopardize progress toward several UN Sustainable Development Goals, including ending poverty, ensuring food security, and promoting peace and justice. 



Addressing the drought crisis is not merely a matter of environmental stewardship - it is a necessity for global stability and resilience.



<h2 class="wp-block-heading" id="h-african-nations-push-for-stronger-measures">African nations push for stronger measures</h2>



African countries stood united in pushing for a binding agreement. 



One African delegate, speaking anonymously, shared the hope for mandatory drought preparation plans, stating: "It's the first time I've seen Africa so united, with a strong united front, with respect to the drought protocol."



The divide between nations became clear as developed countries preferred a looser "framework" approach rather than binding commitments. 



This position frustrated both African nations and Indigenous groups that were seeking stronger measures.



Praveena Sridhar of Save Soil suggested moving forward despite the lack of agreement.



"The absence of a protocol from COP16 shouldn't delay progress," said Sridhar, noting that governments can still support farmers through sustainable land management programs.



<h2 class="wp-block-heading" id="h-financial-commitments-and-future-plans">Financial commitments and future plans</h2>



The talks weren't without some progress. Various organizations, including the Arab Coordination Group and the Riyadh Global Drought Resilience Partnership, pledged over $12 billion toward <a href="https://www.earth.com/news/toilet-to-tap-california-approves-wastewater-recycling-amid-drought-crisis/" target="_blank" rel="noreferrer noopener">drought resilience efforts</a>.



However, this falls short of the UN's estimated need of $2.6 trillion for land restoration by 2030.



Saudi Environment Minister Abdulrahman AlFadley emphasized his country's commitment, stating they are dedicated "to working with all parties to preserve ecosystems, enhance international cooperation to combat desertification and land degradation, and address drought."



<h2 class="wp-block-heading" id="h-finding-common-ground">Finding common ground</h2>



The discussions revealed an interesting dynamic, as noted by Sridhar. Unlike climate talks that focus on controversial topics like fossil fuels, land preservation discussions offer more common ground.



"Attending to land, agriculture lands, farmers, livestock – it's not a contested subject. Nobody's going to say 'I don't want food.' The use of fossil fuels or not is a very polarizing subject. This is not," said Sridhar.



The next opportunity for progress will come at COP17 in Mongolia in 2026, where nations again hope to finalize a <a href="https://www.earth.com/news/formal-agreement-needed-to-define-the-current-level-of-global-warming/" target="_blank" rel="noreferrer noopener">global drought agreement</a>.

Going green: Which U.S. states are the least environmentally friendly?

A new comprehensive assessment led by Portland Real Estate has...

A new study led by the <a href="https://www.ox.ac.uk/">University of Oxford</a> is shedding light on a concerning issue that many may have overlooked. The researchers have determined that sewage pollution is more detrimental to <a href="https://www.earth.com/news/hypoxia-is-a-serious-problem-in-rivers-worldwide/">rivers</a> than agriculture.



The study was launched ahead of World Rivers Day, which is celebrated on September 24th.&nbsp;



The researchers found that even when sewage undergoes treatment, its discharge into rivers affects water quality far more than runoff from surrounding land use.



<h2 class="wp-block-heading" id="h-focus-of-the-study-nbsp">Focus of the study&nbsp;</h2>



The experts took into consideration three pollution sources: treated sewage discharge, agriculture, and urban run-off.&nbsp;



The team tested four rivers in England both up- and downstream of sewage discharge points across three different months.



While water companies in the UK have the green light to release treated wastewater into rivers, untreated wastewater can also be released during heavy rainfalls, a phenomenon termed as storm overflow.&nbsp;



This not only leads to significant ecological ramifications but can also jeopardize human health if that water is utilized for drinking, recreational, or agricultural activities.



<h2 class="wp-block-heading" id="h-key-findings-from-the-study">Key findings from the study</h2>



<h3 class="wp-block-heading" id="h-sewage-is-a-primary-pollutant">Sewage is a primary pollutant</h3>



Sewage, whether treated or untreated, is responsible for the spike in nutrients, algae, and sewage fungus in rivers.&nbsp;



Moreover, it severely alters the ecosystem by changing the composition of plant, animal, and microbial communities in the water.



<h3 class="wp-block-heading" id="h-shift-in-river-communities">Shift in river communities</h3>



Downstream of sewage input, rivers exhibited a noticeable shift in macroinvertebrate and algae communities.&nbsp;



The surge in resilient groups like cyanobacteria and worms is especially alarming. Cyanobacteria are infamous for releasing toxic chemicals that can be lethal to many aquatic species.



<h3 class="wp-block-heading" id="h-agriculture-s-role">Agriculture's role</h3>



Though sewage discharge is a dominant threat, agricultural run-off also contributes to the degradation of water quality, especially harming specific sensitive insect groups such as mayflies, stoneflies, and caddisflies.



<h2 class="wp-block-heading" id="h-addressing-the-issue">Addressing the issue</h2>



“Our study highlights the disproportionate impact that sewage discharge has on river quality, presenting an urgent need for a comprehensive action plan targeting the sewage discharge problem," said study lead author Dr. Dania Albini.



"Improvements to waste water plants should be implemented along with more regulations. These efforts are crucial in safeguarding the integrity and safety of our rivers - fundamental elements of both ecosystems and human wellbeing.”



Ecological state of UK waterways



The revelations from the study are timely, especially considering the deteriorating state of the UK's waterways.&nbsp;



With over 90% of freshwater habitats in England's vital rivers being affected by various pollutants, a holistic strategy addressing pollution is imperative for the well-being of both the environment and its inhabitants.



“There is ongoing debate about the cause of the poor ecological state of many rivers in the UK because it is difficult to disentangle different pollution sources," said study senior author Dr. Michelle Jackson.



"Here, we show that even treated sewage appears to have a stronger influence on river communities than pollution from the surrounding land. This important information should be used to prioritize the management and conservation of our rivers moving forward.”



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



James Wallace, CEO of the UK-based charity River Action, said the research demonstrates yet again the damage from unregulated water companies and agriculture.&nbsp;



"In addition to the catastrophic impact on wildlife from nutrient pollution, the public should be aware that sewage systems do not remove dangerous bacteria such as E.coli and intestinal enterococci from treated sewage," said Wallace.



"For instance, recent citizen science on the River Thames found that Thames Water’s outflows often have four to five times the safe levels of bacteria, that has likely caused serious illness in swimmers and rowers."&nbsp;



"When will the government make water companies and farms clean up their act, especially in places where human lives and sensitive protected habitats are threatened?”



<h2 class="wp-block-heading" id="h-early-detection-system">Early detection system</h2>



The researchers have also developed a new method to detect potentially dangerous "sewage fungus" outbreaks.



This mix of fungus, algae, and bacteria causes unpleasant smells and severely reduces oxygen levels, which can cause mass fish mortality.



"Rapid identification of sewage fungus pollution events will allow early intervention which would help prevent any potential negative consequences for local wildlife," said Dr. Jackson.



The research is published in the journal <a href="http://dx.doi.org/10.1111/gcb.16934">Global Change Biology</a>.

Geographers from the University of Lincoln, UK, report that approximately 23 million people globally reside on floodplains tainted with dangerously elevated levels of toxic waste. 



This alarming revelation stems from an extensive research effort involving the mapping of 22,609 active and 159,735 abandoned metal mines, and was published in the renowned journal <a href="https://www.science.org/doi/10.1126/science.adg6704" target="_blank" rel="noreferrer noopener">Science</a>.



<h2 class="wp-block-heading" id="h-concerning-levels-of-toxic-waste-in-rivers">Concerning levels of toxic waste in rivers</h2>



The research led by Mark Macklin focused on discerning the levels of pollution percolating into the waterways from harmful contaminants such as lead, copper, zinc, and arsenic. The meticulous analysis concluded that about 479,200 kilometers of river channels covering 164,000 square kilometers are contaminated by toxic waste from hazardous chemicals on a global scale.



Macklin elucidates that the innovative method devised for this study empowers governments, environmental regulators, the mining sector, and local communities to predict the diffusion of mine waste in river systems around the globe. This prediction tool is a first, enabling accurate assessment of the mining impacts on ecosystems and human health, both offsite and downstream.



<h2 class="wp-block-heading" id="h-innovative-study-methodology">Innovative study methodology</h2>



Macklin expressed his optimism that the new methodology would facilitate the mitigation of environmental ramifications stemming from both historical and contemporary mining practices. He stressed the importance of minimizing the impacts of future mining developments on communities. The focus should be on preserving food and water security amidst rising global demand for metals and minerals essential for transitional technologies.



This study is anticipated to have far-reaching impacts, aiding in the reduction of environmental damage induced by previous and current mining methodologies. Professor Chris Thomas, a key contributor to the research analysis, emphasized the urgency of global metal mining expansion to facilitate the transition to green energy. Thomas acknowledged the substantial global contamination mapped in the study as a legacy from the industrial era, advocating for modern mining to prioritize environmental sustainability.



He further explained, "Our methods, which also operate effectively at local scales, introduce a vital new strategy in this process." To implement this strategy, an applied unit of their research center, Water and Planetary Health Analytics, has been established to collaborate with the sector.



<h2 class="wp-block-heading" id="h-modern-mining-and-environmental-concerns">Modern mining and environmental concerns</h2>



Experts believe this development is crucial, especially when transitional technologies are experiencing an exponential demand for metals and minerals. This study is not only a beacon of knowledge shedding light on the environmental impacts of mining but also a compass guiding modern mining towards environmental sustainability and human safety. 



The approach proposed by the team serves as an invaluable asset for gauging and mitigating the repercussions of mining activities on ecological and human health.



This comprehensive research underscores the significance of refining mining practices and presents a new paradigm in environmental conservation. The goal is to enable a harmonious coexistence between mining endeavors and ecological well-being. 



The implications of this study are pivotal, offering a road map for industries, regulators, and communities to navigate the complexities of environmental conservation in mining, all while aligning with the escalating need for metals in advancing green technologies.

Swedish researchers from Stockholm University and Linne University have unveiled a startling discovery of vast methane leaks erupting from the seabed of the Baltic Sea. This revelation has caused renewed scrutiny in environmental circles and prompted deeper investigation into the underlying causes and potential ramifications.



The scientists stumbled upon methane bubbles escalating up to 370 meters in a delimited area of 20 square kilometers off the southeastern coast of Sweden. This discovery illustrates a phenomenon unseen in the ongoing study of underwater ecosystems and <a href="https://www.earth.com/news/scientists-find-a-new-way-to-locate-methane-leaks/" target="_blank" rel="noreferrer noopener">methane emissions</a>.



<h2 class="wp-block-heading" id="h-intense-and-intact-bubbles">Intense and intact bubbles</h2>



Christian Stranne, a notable member of the research team from <a href="https://www.su.se/cmlink/stockholm-university" target="_blank" rel="noreferrer noopener">Stockholm University</a>, in an official statement, emphasized the uniqueness of the methane leak conditions. He noted that the oxygen-free waters of the Baltic Sea might facilitate the intact rise of the bubbles to the surface. 



Stranne voiced his astonishment over witnessing intense bubbles originating from such unprecedented depths, stating, “We know that methane gas can bubble up from shallow seabeds near the Baltic Sea coast, but I’ve never seen such intense bubbles before – and definitely not from such a deep area."



<h2 class="wp-block-heading" id="h-more-baltic-sea-methane-leaks-suspected">More Baltic Sea methane leaks suspected</h2>



This discovery suggests the potential presence of similar methane leaks in different regions of the Baltic Sea, due to the atypical levels of methane discovered. The unusual conditions have spurred the team into further exploratory and analytical endeavors to unravel the mystery behind the high methane levels in the area.



Marcelo Ketzer, the project leader and a professor of environmental science at Linne University, echoed Stranne's concerns and insights. He underscored the current lack of comprehensive knowledge about the factors influencing methane production in deeper regions and the trajectory of the released methane. Ketzer also stressed the urgent need for understanding the dynamics at play in these deeper realms of the Baltic Sea.



<h2 class="wp-block-heading" id="h-possible-link-to-the-nord-stream-pipeline">Possible link to the Nord Stream Pipeline</h2>



This instance of methane leak aligns temporally with the ruptures in the Nord Stream Pipeline under the Baltic Sea reported a year prior, considered by the <a href="https://www.unep.org/" target="_blank" rel="noreferrer noopener">United Nations Environment Programme</a> (UNEP) to be the largest single release of methane ever recorded.



Last September, the pipeline, pivotal for the transport of natural gas from Germany to Russia, suffered extensive damage due to sudden underwater explosions, leading to unanticipated and significant methane emissions.



This revelation fuels speculation and concerns over environmental safety and integrity, highlighting the necessity for meticulous analysis and research to comprehend the production, release, and impact of <a href="https://www.earth.com/news/melting-arctic-glaciers-are-releasing-a-new-source-of-potent-methane-emissions/" target="_blank" rel="noreferrer noopener">methane</a> from the seabed. 



The increased scrutiny and extensive research spurred by this discovery will be paramount in understanding the environmental and ecological implications of methane leaks, and in developing strategies to monitor and mitigate any detrimental impacts on marine ecosystems and climate.



The concerted efforts by the research teams at Stockholm and Linne Universities to probe deeper into this phenomenon will play a crucial role in shaping our understanding of the methane cycle in the Baltic Sea and potentially in other similar ecosystems globally. The revelations and insights gleaned from their ongoing research will be instrumental in advancing scientific knowledge and environmental conservation initiatives.

Large methane leaks discovered in the Baltic Sea

Swedish researchers from Stockholm University and Linne University have unveiled...

Macro,Image,Of,A,Dead,Bee,On,A,Leaf,From

Recent research discovered that over 10% of English river sites contain hazardous levels of pesticides that are toxic to bees and also prohibited by the European Union (EU). 



The alarming levels of neonicotinoids, particularly in rivers in the east of England, South East, and West Midlands, expose severe environmental concerns and potential risks to aquatic life and human health.



<h2 class="wp-block-heading" id="h-damaging-presence-of-neonicotinoids">Damaging presence of neonicotinoids</h2>



Of the 283 river sites that underwent examination by the Environment Agency between 2020 and 2022, at least one of the five neonicotinoids was present in 29. It is distressing to note that 55% of these 29 sites exhibited one or more neonicotinoids above the <a href="https://echa.europa.eu/environmental-quality-standards" target="_blank" rel="noreferrer noopener">Environmental Quality Standard</a> (EQS) set by the EU, deemed safe for aquatic species. Furthermore, over four times the acceptable limit of one or more pesticides marked 21% of the sites.



The research brought to light the presence of clothianidin, imidacloprid, and thiamethoxam. These pesticides, banned in the UK since 2018 for outdoor crops, are notorious for their harmful impacts on <a href="https://www.earth.com/news/omega-3-oil-may-help-protect-pollinators-from-pesticides/" target="_blank" rel="noreferrer noopener">bees</a> and aquatic organisms. 



Thiacloprid and Acetamiprid were also identified. The former was prohibited in 2020 due to potential detrimental effects on human health, while the latter, still allowed in the UK, is known to accumulate and damage various living organisms.



<h2 class="wp-block-heading" id="h-areas-with-highest-concentrations">Areas with highest concentrations</h2>



The east of England, the West Midlands, and Yorkshire and Humber showcased the highest concentrations of neonicotinoids at single sites. The rivers Ivel, Nene, Ouse, Tame, and Waveney in these regions were the most prevalent for pesticide use.



Tessa Wardley, the Director of Communications and Advocacy at the <a href="https://theriverstrust.org/" target="_blank" rel="noreferrer noopener">Rivers Trust</a>, emphasized the likely understatement of the actual extent of neonicotinoid pollution in English rivers due to infrequent and inadequate monitoring by the <a href="https://www.gov.uk/government/organisations/environment-agency" target="_blank" rel="noreferrer noopener">Environment Agency</a>, especially during wet weather when the risk of rapid flushing of pesticides into rivers is heightened.



<h2 class="wp-block-heading" id="h-controversy-and-debate">Controversy and debate</h2>



This revelation coincides with ongoing debates within the government regarding the renewal of the usage of thiamethoxam for the fourth consecutive year. This debate has sparked controversy due to previous emergency authorizations contradicting expert counsel. 



The EU Court of Justice, in January 2023, deemed such emergency authorizations of seeds treated with banned neonicotinoids as violations of EU law.



Nick Mole, Policy Officer at Pesticide Action Network UK, termed the findings as “hugely concerning,” urging the UK government to put a halt to ‘emergency’ extensions for the use of <a href="https://www.earth.com/news/neonicotinoids-kill-bees-and-threaten-hundreds-of-species/" target="_blank" rel="noreferrer noopener">banned pesticides</a> and to institute a robust and well-funded monitoring system for all UK water bodies urgently.



Barnaby Coupe, Land Use Policy Manager at The Wildlife Trusts, also criticized the UK government's ongoing approval of toxic pesticides, which he claims has ignored scientific findings and expert advice, resulting in a significant reduction in wildlife.



<h2 class="wp-block-heading" id="h-government-actions">Government actions</h2>



In response, a spokesperson for the Department for Environment, Food, and Rural Affairs (DEFRA) assured that their comprehensive Plan for Water is addressing every source of pollution through enhanced investment, stricter regulation, and tougher enforcement. 



They further highlighted the government's commitment to minimizing the risks and impacts of pesticides and reducing the use of insecticides by farmers through increased funding and sustainable farming incentives.



In summary, the new research has sparked renewed urgency and concern regarding the hazardous levels of prohibited pesticides in English rivers, revealing the far-reaching impacts on wildlife, aquatic life, and potentially human health. 



The government is under increased pressure to enhance monitoring, regulation, and enforcement to combat the rising levels of harmful pesticides and to reconsider the allowances and extensions granted for the use of such chemicals in the agriculture sector.

The latest official study on climate-related mortality highlights pressing concerns about the escalating crisis of climate change and its direct impact on public health in England. The <a href="https://www.ons.gov.uk/" target="_blank" rel="noreferrer noopener">Office of National Statistics</a> (ONS) published a study on Friday, revealing that in 2022, England witnessed approximately 4,507 heat-related deaths.



<h2 class="wp-block-heading" id="h-extreme-global-temperatures">Extreme global temperatures</h2>



The results of this study indicate a rising trend in heat-related deaths over the past few years. It has been noted by the <a href="https://www.metoffice.gov.uk/" target="_blank" rel="noreferrer noopener">Met Office National Forecaster</a> that the previous century has marked 10 of the warmest years ever recorded in Britain, showcasing a changing climate leaning towards more extreme temperatures. 



In fact, July 2022 saw Britain experiencing its hottest day ever recorded, with temperatures soaring above 40 degrees Celsius amidst a European <a href="https://www.earth.com/news/climate-change-may-have-an-unknown-accomplice-driving-record-heat/" target="_blank" rel="noreferrer noopener">heatwave</a> driven by climate change.



However, it is crucial to note that the ONS has categorized the data as experimental, cautioning against making individual yearly comparisons without considering broader contexts and variables. The ONS statement elaborates that alterations in climate, reflecting more extreme temperatures, would inevitably escalate the number of heat-related deaths in England.



<h2 class="wp-block-heading" id="h-disparities-in-mortality-risks">Disparities in mortality risks</h2>



A closer look at the study reveals alarming disparities in mortality risks across regions. London presented the highest mortality risk due to the soaring temperatures of about 29 degrees Celsius recorded at the time. 



The metropolis saw death risks three times higher than in other regions where temperatures ranged between 9 degrees and 22 degrees Celsius.



<h2 class="wp-block-heading" id="h-comparative-data-on-heat-related-deaths">Comparative data on heat-related deaths</h2>



Between 1988 and 2022, the study found approximately 51,670 deaths recorded during the hottest 5% of days. Interestingly, during the same period, a much higher number of deaths, totaling 199,298, occurred during the coldest 5% of days. 



This contrast emphasizes the importance of a holistic approach to studying climate-related mortality, considering both extremes of the temperature spectrum.



<h2 class="wp-block-heading" id="h-a-respite-in-2023">A respite in 2023</h2>



In the ongoing struggle with climate change globally, the summer of 2023 provided a slight reprieve, not reaching the extreme levels recorded in 2022. The Met Office recorded the summer of 2023 as the eighth warmest summer in Britain’s history. Nevertheless, a recent heatwave this month did see temperatures climbing above 30 degrees Celsius for a consecutive seven days, maintaining the urgency around addressing climate-induced temperature extremes.



In summary, the official study by ONS highlights the urgency of addressing the tangible and escalating impacts of climate change on human health, particularly in regions experiencing extreme temperature variations. 



While data interpretation requires cautious approaches, the discernible rise in heat-related deaths underscores the crucial need for effective climate mitigation and adaptation strategies to safeguard public health.



Strategies could include enhanced early warning systems, improved urban planning to counteract heat island effects, particularly in densely populated areas like London, and strengthened healthcare systems prepared to respond to climate-induced health crises. 



The battle against climate change is not just about protecting the environment; it is intrinsically linked to preserving human life, and the findings from this study emphasize the immediate and tangible human cost of a warming planet.

Over 4500 heat-related deaths recorded in England

The latest official study on climate-related mortality highlights pressing concerns...

Spiny,Crayfish,With,Nippers,Raised

The Environmental Protection Authority (EPA) of New South Wales confirmed on Friday that the crayfish kill of numerous giant spiny crayfish in the Blue Mountains last month resulted from contamination by an insecticide, bifenthrin. 



This revelation follows a gruesome discovery by a tour guide who found up to 1,000 dead and dying crayfish in a tributary of Hazelbrook Creek, near Horseshoe Falls, revealing the disturbing impact of pollution on marine life in the region.



<h2 class="wp-block-heading" id="h-discovery-and-investigation">Discovery and investigation</h2>



The contaminated tributary is located next to a predominantly residential area of Hazelbrook town and drains a sub catchment. Suspecting a pollutant as the cause, the <a href="https://www.epa.nsw.gov.au/" target="_blank" rel="noreferrer noopener">EPA</a> cooperated with the Blue Mountains city council staff to trace the source of the contamination. 



Crayfish carcasses underwent extensive analysis at an EPA laboratory in Lidcombe where detailed tests revealed the presence of bifenthrin in the water, sediment, and crayfish samples from the tainted creek.



<h2 class="wp-block-heading" id="h-the-role-of-bifenthrin">The role of bifenthrin</h2>



Bifenthrin is a common insecticide employed for controlling various pests such as termites, spiders, ants, and cockroaches. Despite its widespread use, it poses severe risks to crayfish and other marine species. 



It is worth noting that the EPA has absolved glyphosate and other herbicides, used by the Blue Mountains city council, from being the causes of the crayfish deaths and clarified that the council is not under investigation in the ongoing inquiry to find the contamination source.



<h2 class="wp-block-heading" id="h-crayfish-kill-impacts-on-biodiversity">Crayfish kill impacts on biodiversity</h2>



This is not the first instance of pollution affecting giant spiny crayfish in the area. In 2012, bifenthrin contamination in Jamison Creek near the World Heritage-listed Wentworth Falls caused the largest-ever mass crayfish kill recorded. 



The contamination, which infiltrated the creek through stormwater drains, decimated other macroinvertebrates and severely impaired aquatic biodiversity, plummeting the number of taxonomic families in the creek from 22 to three.



Giant spiny crayfish, native to Australia, face existential threats from pesticides, runoff, and habitat loss, and trapping them in the Blue Mountains’ swamps or waterways is prohibited. These incidents underscore the urgent need for stringent measures to preserve these unique creatures and the overall biodiversity of the region.



<h2 class="wp-block-heading" id="h-calls-for-responsibility-and-caution">Calls for responsibility and caution</h2>



The acting Chief Executive of the <a href="https://www.nature.org.au/" target="_blank" rel="noreferrer noopener">Nature Conservation Council of New South Wales</a>, Brad Smith, emphasized the ramifications of this incident, remarking that it serves as “a reminder about how careful businesses and residents need to be with chemicals, especially around waterways”. 



Smith stresses the collective responsibility, especially in ecologically sensitive areas like the Blue Mountains, to protect the region’s precious world heritage. The Nature Conservation Council is eager for the EPA to pinpoint the source of this devastating spill, highlighting the crucial role of vigilance and responsibility in preventing such environmental catastrophes.



In summary, the EPA’s findings bring to light the delicate balance of our ecosystems and the profound impact human activities can have on the environment, serving as a stark reminder of the caution needed in handling <a href="https://www.earth.com/news/omega-3-oil-may-help-protect-pollinators-from-pesticides/" target="_blank" rel="noreferrer noopener">chemicals</a>, particularly near water bodies. 



The pursuit to uncover the contamination source is crucial, not only to prevent further loss of aquatic life but also to uphold the integrity of the ecological sanctuaries such as the Blue Mountains.

Insecticide responsible for major crayfish kill in Australia

The Environmental Protection Authority (EPA) of New South Wales confirmed...

A recent study has revealed that socially vulnerable groups in the West, particularly in Oregon and Washington, face a heightened exposure to <a href="https://www.earth.com/news/record-breaking-amount-of-co2-released-by-wildfires-in-2021/">wildfires</a>. As wildfire risks amplify, these findings spotlight a critical intersection of environmental and societal challenges.



<h2 class="wp-block-heading" id="h-understanding-social-vulnerability">Understanding social vulnerability</h2>



Social vulnerability refers to specific traits of individuals or communities, including age, race, ethnicity, and socioeconomic status, that increase their likelihood of harm from potential hazards.&nbsp;



Over the decade from 2011 to 2021, there was a significant rise in the exposure of socially vulnerable individuals to wildfires in Oregon, Washington, and California. The exposure of such groups increased threefold compared to the previous decade.



<h2 class="wp-block-heading" id="h-inequitable-effects-nbsp">Inequitable effects&nbsp;</h2>



Study co-author Erica Fleishman is a professor in the College of Earth, Ocean, and Atmospheric Sciences at <a href="https://oregonstate.edu/">Oregon State University</a> and also directs the Oregon Climate Change Research Institute



“There has been general knowledge that the number of destructive wildfires and total impacted population are increasing and that hazards have inequitable effects on people,” said Professor Fleishman.&nbsp;



“This research is helping us understand how much more risk people are facing, where and why. The risks are clearly higher for the people who are going to have more difficulty recovering.”



<h2 class="wp-block-heading" id="h-focus-of-the-study">Focus of the study</h2>



The study was led by doctoral student Arash Modaresi Rad from Boise State University and his mentor, Mojtaba Sadegh, an associate professor of Civil Engineering.&nbsp;



The researchers examined satellite imagery, U.S. Census data, and population maps to grasp the links between wildfire exposure and social vulnerability from 2000 through 2021.



During this time span, roughly 500,000 individuals in Oregon, Washington, and California were directly affected by wildfires. A significant majority of these affected individuals resided in California.



<h2 class="wp-block-heading" id="h-disproportionate-risks">Disproportionate risks</h2>



The researchers used data from the Social Vulnerability Index from the Centers for Disease Control and Prevention. This index gauges a community's readiness and ability to address and recover from hazards, using parameters like socioeconomic status, minority status, housing, and transportation.&nbsp;



The analysis showed that while fire risks surged for everyone, socially vulnerable groups faced a disproportionate escalation in risk.



The variations in vulnerability among the three states are pronounced. For instance, in California, a mere 8% of those affected by wildfires were from high vulnerability groups, translating to almost 37,000 individuals.&nbsp;



In contrast, Oregon and Washington saw exposure rates of 45% and 44% respectively for their socially vulnerable populations.



<h2 class="wp-block-heading" id="h-urban-vs-rural-exposure">Urban vs. rural exposure</h2>



One intriguing revelation from the study was the difference in wildfire exposure based on urban and rural settings. California's majority of exposed individuals lived in cities, while those in Oregon and Washington predominantly resided in rural areas.



“These data show that there is no single strategy for wildfire preparation and response,” Fleishman said. “Instead, they indicate responses might be honed to reflect the needs of individual communities with different risk factors.”



In some areas, that may mean paying particular attention to residents who are older or mobility limited, and in other areas, it might mean adapting materials to ensure they can reach non-English speaking communities, said the researchers.



“The underlying factors, such as business decisions, that exacerbate climate change and increase wildfire risk also decrease the resilience of at-risk communities,” Sadegh said. “A more just and equitable economy can mitigate the compounded effects of physical and social vulnerabilities.”



The research is published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.adh4615">Science Advances</a>.

Wildfires amplify risks for socially vulnerable populations in Western states

A recent study has revealed that socially vulnerable groups in...

Two recent studies led by <a href="https://www.cornell.edu/">Cornell University</a> has found that, although human-made ponds both sequester and release greenhouse gases, when added up, they may unfortunately be net emitters.&nbsp;



These studies aim to elucidate the consequential impacts of both anthropogenic and natural ponds on the global greenhouse gas budget – a field still shrouded in uncertainty.



“Global climate models and predictions rely on accurate accounting of greenhouse gas emissions and carbon storage,” said Meredith Holgerson, an assistant professor of Ecology and Evolutionary Biology at Cornell and the senior author of both studies.



<h2 class="wp-block-heading" id="h-focus-of-the-research-nbsp">Focus of the research&nbsp;</h2>



Prior estimates by Holgerson and her team suggest that ponds, categorized as bodies of water five hectares (12 acres) or smaller – with an estimated total of one billion such ponds globally – could be responsible for approximately five percent of global methane emissions.&nbsp;



However, the real figure might range from half to double of this estimate, highlighting the necessity for accurate measurements across diverse water bodies.



The first paper, “<a href="https://aslopubs.onlinelibrary.wiley.com/doi/full/10.1002/lol2.10351">High Rates of Carbon Burial Linked to Autochthonous Production in Artificial Ponds</a>,” published on August 18 in the journal Limnology and Oceanography Letters, examined the amount of carbon sequestered in 22 of the Cornell Experimental Ponds. Established in 1964, these 50 identical ponds offer meticulously controlled environments and a wealth of data from preceding research, enabling scientists to assess the impact of management activities on carbon storage.



<h2 class="wp-block-heading" id="h-carbon-sinking-rates">Carbon sinking rates</h2>



Through a comprehensive examination of past management practices and in-depth measurements of sediment cores and thickness, the researchers determined the <a href="https://www.earth.com/news/carbon-sinks-are-a-powerful-weapon-against-climate-change/">carbon sinking</a> rates in these ponds. The findings revealed that these rates were comparable to those of wetlands and mangroves and surpassed those of lakes.



The experts also discovered the influential role of aquatic flora, fish, and certain nutrient ratios on carbon sinking rates. Proper nutrient balance enhances plant growth, leading to increased carbon deposition at the pond’s bottom after plant decay.



Despite the paucity of data on organic carbon sequestration in natural ponds, the extrapolation of their findings allowed the researchers to gauge the total carbon sinking rate in both natural and artificial ponds globally.&nbsp;



The investigation revealed that these ponds might account for 65 percent to 87 percent of the total carbon sequestered by all lakes, underscoring a global underestimation of carbon sequestration in ponds and lakes.



<h2 class="wp-block-heading" id="h-greenhouse-gas-emissions-nbsp">Greenhouse gas emissions&nbsp;</h2>



The second study, “<a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL104235">High Intra-Seasonal Variability in Greenhouse Gas Emissions from Temperate Constructed Ponds</a>,” published on September 19 in the journal Geophysical Research Letters, delved into the seasonal variance in greenhouse gas emissions, predominantly carbon dioxide and methane, from four Cornell Experimental Ponds.



“Global estimates of greenhouse gas budgets from ponds are highly uncertain, in part due to lack of temporal measurements,” said study lead author Nicholas Ray, a postdoctoral fellow in Holgerson’s lab.&nbsp;



The researchers found that methane, a gas 25 times more impactful on global warming than carbon dioxide, constituted the majority of the annual emissions, with significant seasonal fluctuations.



<h2 class="wp-block-heading" id="h-regular-monitoring-is-needed">Regular monitoring is needed</h2>



The research outlined how ponds assimilate carbon dioxide during the plant growth season in early summer and release it later, with methane emissions being consistent but varying greatly on a week-to-week basis, indicating the necessity of regular monitoring.



Moreover, the study highlighted the correlation between water stratification, methane production, and increased emissions, emphasizing the significance of frequent sampling in mitigating methane levels.&nbsp;



The microbial production of methane on pond beds was found to be contingent on low-oxygen conditions, which is disrupted when water is mixed by winds or sudden cooling.



<h2 class="wp-block-heading" id="h-methane-mitigation-strategies-nbsp">Methane mitigation strategies&nbsp;</h2>



Both studies reveal that, due to the substantial methane emissions, ponds are net contributors to greenhouse gases, overshadowing the carbon sequestered in the sediments.&nbsp;



However, the studies also highlight the potential for transitioning ponds from net emitters to net absorbers of greenhouse gases through the application of methane mitigation strategies, such as the use of bubblers or underwater circulators.



“If we could reduce that methane number, we could potentially flip these ponds from being net emitters to net sinks, but we have to get a handle on that methane,” Holgerson concluded.

Ponds release more greenhouse gases than they store

Two recent studies led by Cornell University has found that,...

Over the past 20 years, the world has witnessed a concerning decline in coral reefs, a crucial ecosystem that supports about 25 percent of all marine life. Extreme weather events have primarily driven this loss of reefs, particularly due to widespread <a href="https://www.earth.com/news/rescue-underway-florida-is-battling-an-unprecedented-coral-bleaching-crisis/">coral bleaching</a>.



The Great Barrier Reef, the world's most extensive coral reef system, has not been spared, with a shocking 91% of its reefs undergoing bleaching in the years 2016 and 2017.



As the frequency and intensity of mass bleaching events is expected to increase in the near future, scientists have been urgently searching for countermeasures.&nbsp;



<h2 class="wp-block-heading" id="h-reef-restoration-nbsp">Reef restoration&nbsp;</h2>



The Reef Restoration and Adaptation Program (RRAP) is dedicated to creating strategies to help coral reefs withstand and bounce back from the rising ocean temperatures.&nbsp;



A recent study led by Dr. Peter Butcherine from <a href="https://www.scu.edu.au/" target="_blank" rel="noreferrer noopener">Southern Cross University</a> has revealed a potential new solution to help corals recover by shading them. As part of the RRAP, the researchers examined the effectiveness of shading on two coral species.



The study primarily focused the yellow scroll coral (Turbinaria reniformis) and whisker coral (Duncanopsammia axifuga).



<h2 class="wp-block-heading" id="h-promising-results">Promising results</h2>



By reducing sunlight by 30% for a span of four hours around solar noon, the onset of coral bleaching in certain shallow corals can be slowed down, according to the study. This approach to intermittent shading was shown to ease the impact of light stress.



The experts found that shaded corals bleached significantly less than unshaded ones, and corals that were shaded for 24 hours bleached less than those shaded for four hours. Higher water temperatures also favored bleaching.&nbsp;



<h2 class="wp-block-heading" id="h-shade-as-a-refuge">Shade as a refuge</h2>



The research also introduced the concept of degree heating weeks (DHW). Once water temperatures surpass the maximum monthly average by more than 1°C, corals begin to accumulate DHW.&nbsp;



Crossing a threshold of four consecutive degree heating weeks can lead to considerable coral bleaching. Interestingly, shading proved effective in delaying the bleaching response by up to three DHW.



<h2 class="wp-block-heading" id="h-complex-interactions">Complex interactions</h2>



Not all corals react to shading in the same manner. For instance, while the yellow scroll coral benefited from just four hours of daily shading, the whisker coral needed a 24-hour shading period to showcase a positive response.&nbsp;



“The complex nature of coral interactions with their environment means there are likely to be a range of responses to shading. We showed that coral species can respond differently when shaded, but these differences were not necessarily detrimental, just different from each other,” explained Dr. Butcherine.



While shading offers some reprieve, it might not be enough during intense and prolonged marine heatwaves, noted the researchers.



<h2 class="wp-block-heading" id="h-shading-reefs">Shading reefs</h2>



"This work directly informs the development of cooling and shading interventions to help protect the Great Barrier Reef during future bleaching events,” said Dr Daniel Harrison, a researcher at Southern Cross University and program lead of RRAP Cooling and Shading.&nbsp;



“Coral reefs are a critically important ecosystem so it is vital to investigate all the possible ways we can help them survive climate change.”



There are several ways to shade reefs, including the use of artificial coverings and seawater fogging systems.&nbsp;



“The focus of the fogging technologies we are developing is for deployment at an individual reef site of some tens of hectares in size,” said Harrison.&nbsp;



The team’s efforts are currently aimed at localized cooling and shading of small high-value reef environments.



“Our trials show some promising results, but there is still more research and development required before the current technologies are ready for scaled up deployment in the field,” Harrison concluded.



The research is published in the journal <a href="http://dx.doi.org/10.3389/fmars.2023.1162896" target="_blank" rel="noreferrer noopener">Frontiers in Marine Science</a>.

Shading the Great Barrier Reef may slow coral bleaching

Over the past 20 years, the world has witnessed a...

Climate change is reshaping bird habitats and populations across the United Kingdom, presenting both challenges and opportunities for native and migratory species. 



Scientists note that this environmental shift is producing "winners and losers" among bird populations, impacting not only the avian residents but also the bird-watching community in Britain.



<h2 class="wp-block-heading" id="h-rising-new-sightings-the-winners">Rising new sightings: The winners</h2>



According to a recent report by the BBC, bird enthusiasts in the UK are witnessing unprecedented sightings of non-native species, such as the black-winged stilts and bee-eaters -- migrants previously seldom seen on British shores. 



Bird species like reed warblers are leveraging the extended, warmer summers to increase their progeny, while others like the Cetti's warbler, which colonized the UK decades ago, are progressively extending their range north.



<h2 class="wp-block-heading" id="h-diminishing-native-species-the-losers">Diminishing native species: The losers</h2>



Conversely, the shifting climate is posing significant threats to species like cuckoos and willow warblers, which are experiencing sharp declines in Southern Britain. Dr. Dave Leech, the Head of Ringing at the <a href="https://www.bto.org/" target="_blank" rel="noreferrer noopener">British Trust for Ornithology</a>, spoke to the BBC about the precarious plight of <a href="https://www.earth.com/news/cuckoos-are-unable-to-change-their-migrations-in-response-to-climate-change/" target="_blank" rel="noreferrer noopener">cuckoos</a>, stating their populations are in "free fall." 



The changing climate is reducing the availability of food, impeding these birds' ability to refuel before their strenuous journey back over the Sahara to over-winter in Africa. The worry is that future generations might miss out on the distinctive calls of cuckoos, a sound once synonymous with British wildlife.



<h2 class="wp-block-heading" id="h-multi-faceted-pressure-on-bird-populations">Multi-faceted pressure on bird populations</h2>



The precarious balance of the avian ecosystem in the UK is not solely attributed to climate change. Loss of natural habitats like meadows and hedgerows, combined with the usage of pesticides, has led to a decline in nearly half of all bird species in the country. 



The British Trust for Ornithology reports a substantial decrease in the number of wild birds in Britain, witnessing <a href="https://www.earth.com/news/half-of-all-uk-bird-species-are-in-a-state-of-decline/" target="_blank" rel="noreferrer noopener">a drop of 73 million</a> since 1970.



Dr. Leech emphasizes that the changing climate is particularly impactful for migratory birds, which are grappling with extreme weather conditions across various continents, affecting their breeding, wintering, and migrational paths that span thousands of kilometers.



<h2 class="wp-block-heading" id="h-strategic-monitoring-and-mitigation">Strategic monitoring and mitigation</h2>



The continuous efforts of bird ringers and volunteers have been instrumental in monitoring these changes in bird populations, providing valuable insights into their decline. 



Peter, a seasoned bird ringer from Gloucestershire, points out to the BBC that climate change, predominantly driven by human activities, will result in alterations in the avian landscape. While some <a href="https://www.earth.com/earthpedia-articles/the-12-endangered-birds-most-at-risk-of-extinction/" target="_blank" rel="noreferrer noopener">species may disappear</a>, others could become commonplace, shifting the avian biodiversity of the region.



Collecting and analyzing ringing data is crucial for devising effective mitigation strategies against the adverse effects of climate change on bird species. Understanding these shifts will enable more informed conservation strategies, aiming to preserve the rich and diverse bird life in the UK.



<h2 class="wp-block-heading" id="h-preserving-and-conserving-bird-populations">Preserving and conserving bird populations</h2>



In summary, the interplay between climate change and avian species is unveiling a new pattern in <a href="https://www.earth.com/news/bird-populations-are-declining-worldwide/" target="_blank" rel="noreferrer noopener">bird sightings</a> in the UK. While this shift might excite bird lovers with the presence of new species, the decline of traditional inhabitants like the cuckoo raises concerns about the long-term impacts on the biodiversity of the region. 



The proactive role of bird ringers, scientists, and volunteers is essential in monitoring and mitigating the repercussions of these environmental shifts, ensuring the sustenance of diverse bird species for future generations to experience and enjoy.

Bird populations in the UK are being decimated by climate change

Climate change is reshaping bird habitats and populations across the...

After years of negotiations, a historic agreement to <a href="https://www.earth.com/news/un-high-seas-treaty-to-protect-the-oceans-nears-ratification/" target="_blank" rel="noreferrer noopener">protect the world’s oceans</a> was reached in March 2023 at the UN headquarters in New York. In June, the pact was formally adopted by the United Nations.



Just this week, the treaty was signed by 67 countries. The primary objective of the treaty is to safeguard marine life in the high seas – international waters that are not part of any country’s jurisdiction.



Since all countries have the right to fishing and other activities in the high seas, it is important that nations can agree on how this part of the ocean can be used. 



Still yet, only 1.2 percent of the high seas are in protected areas. Outside of these boundaries, marine life is threatened by overfishing and other human activities.



"With the signature of the High Seas Treaty, we can <a href="https://www.earth.com/news/historic-treaty-adopted-to-protect-biodiversity-in-the-high-seas/" target="_blank" rel="noreferrer noopener">safeguard the ocean</a> from human pressures, and get closer to our objective of protecting at least 30% of the planet by 2030," said European Environment Commissioner Virginijus Sinkevičius, calling the treaty "our constitution for the ocean.”



"We only really have two major global commons - the atmosphere and the oceans," noted Georgetown marine biologist Rebecca Helm. While the oceans may draw less attention, protecting this half of earth's surface is absolutely critical to the health of our planet, said Helm.&nbsp;



<a href="https://press.un.org/en/highlights/BBNJ" target="_blank" rel="noreferrer noopener">The Treaty of the High Seas</a> will create a new body to manage conservation of ocean life and establish marine protected areas.



Nichola Clark, an oceans expert at the <a href="https://www.pewtrusts.org/en/" target="_blank" rel="noreferrer noopener">Pew Charitable Trusts</a> observed the treaty discussions in New York. Clark noted that the agreement is a critical step to achieve the U.N. Biodiversity Conference's recent pledge to protect 30 percent of the planet's waters, as well as its land, for conservation.



"This is a once in a generation opportunity to protect the oceans - a major win for biodiversity," said Clark.&nbsp;



The high seas treaty has also established rules for conducting environmental impact assessments for commercial projects in the ocean.



"It means all activities planned for the high seas need to be looked at, though not all will go through a full assessment," said Jessica Battle, an oceans governance expert at the Worldwide Fund for Nature.



"Governments have taken an important step that strengthens the legal protection of two-thirds of the ocean and with it marine biodiversity and the livelihoods of coastal communities," said Gladys Martínez de Lemos, executive director of the nonprofit Interamerican Association for Environmental Defense.



Malin Pinsky, a biologist at <a href="https://www.rutgers.edu/" target="_blank" rel="noreferrer noopener">Rutgers University</a>, said the new treaty is about "acknowledging that the ocean is not a limitless resource, and it requires global cooperation to use the ocean sustainably."

<div class="wp-block-sendtonews-playerselector">[sendtonews key="QGPzYnXEtN-1712599-12187" type="single"]</div>



Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.

Qeshm is separated from the Iranian coast by the Clarence Strait, also known as Khuran.&nbsp;The Hara Forest Protected Area is a network of shallow waterways and forest located between the island and the mainland. This protected region is home to sea turtles, snakes, and more than 150 species of migrating birds.



Qeshm is famous for its wide range of&nbsp;ecotourist&nbsp;attractions, such as the&nbsp;Hara marine forests. According to environmentalists, about 1.5 percent of the world birds and 25 percent of Iran's native <a href="https://www.earth.com/news/female-hummingbirds-avoid-sexual-harassment-by-looking-like-males/">birds</a> annually migrate to the forests, which are the first national geo park in Iran.



Tourists are also drawn to the island to see an age-old Portuguese&nbsp;fort, historic mosques, the&nbsp;Seyyed Mozaffar&nbsp;and&nbsp;Bibi Maryam&nbsp;shrines, and the "Valley of Stars."



The average temperature on the island is 81 degress and the region is often hot and humid. From June to August, the island is described as being oppressively hot. The ideal time to visit is during the winter season.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Inhambane Bay in southeast Mozambique.&nbsp;



"Inhambane Bay is a deep inlet into which the small Mutamba River flows," says ESA. "On one side of the bay lies the historical city of Inhambane, capital of the Inhambane Province, while the sister city of Maxixe, the economic capital of Inhambane, sits across from it. The province is the second largest grower of cashews, after Nampula, and it also produces coconut and citrus fruits."



The beaches of Barra and Tofo are popular with tourists. There are also coral reefs along the long coastline of Inhambane, making it an ideal destination for scuba diving and snorkeling.



"Mozambique’s extensive coastline heightens the country’s vulnerability to tropical cyclones that develop in the Indian Ocean as well as storm surge flooding," says ESA.



"More than half of the population lives in low lying coastal areas, putting communities at risk. Inhambane Bay was dangerously close to where Cyclone Idai made landfall in 2019 causing widespread destruction to the country."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency </a>&nbsp;features the Kangerlussuaq Glacier, one of the largest tidewater outlet glaciers in Greenland. The glacier is located on the east coast of the Greenland ice sheet.



As human-induced climate change continues to drive up temperatures, global ice loss is accelerating at an alarming rate. ESA reports that, over the past decade alone, 3.5 trillion tons of ice have melted from the Greenland ice sheet. This is enough to cover the UK with meltwater 15 meters deep.



Based on satellite imagery, researchers determined that Kangerlussuaq entered a new phase of rapid retreat and acceleration in 2017. In their study, published in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00123/full">Frontiers in Earth Science</a>,&nbsp; the experts report that the glacier's ice front is now at its most retreated position since the early 20th century.



"Given Kangerlussuaq’s previous impacts on both the magnitude and pattern of ice sheet wide mass loss, we predict that its new phase of retreat, acceleration and thinning will markedly enhance the south-east region’s contribution to increasing discharge from the ice sheet," wrote the study authors.&nbsp;&nbsp;



"More broadly, accurate forecasting of the ice sheet’s contribution to sea level rise will require a deeper understanding of, and responses to, these non-linear ice dynamic processes."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the complex relationship between ocean and climate. ESA's Climate Change Initiative will help us understand how oceans influence the climate and how climate change is impacting the oceans.&nbsp;



"Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate," explains ESA.



"As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life."



The amount of heat and carbon dioxide soaked up by the ocean depends on specific variables, including phytoplankton, temperatures, waves, salinity, and ice cover. Satellites can be used to measure these variables from space.



"From their unique vantage point, satellites provide key information for understanding the complexities of our planet and monitoring environmental issues," says ESA.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the importance of monitoring the shape of the sea surface, which is constantly changing. These observations have many applications, such as ship routing, <a href="https://www.earth.com/news/the-modem-ocean-is-a-tough-place-for-whales-to-survive/">ocean</a> current forecasting, and debris tracking.



"A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely," reports ESA.



"The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of the sea surface at very low angles. At these so-called grazing angles, waves and surface roughness have very little impact on the reflection process; the sea surface acts as a very smooth mirror."



Estel Cardellach is the principal investigator at the Institute for Space Studies of Catalonia, who first submitted the idea for the project.



“In a mirror-like reflection the phase of the signal can be tracked – it is continuous," said Cardellach. "Different surface heights result in different phase measurements. It gives a very precise measurement of the surface altitude at a few centimetres’ precision.”



The researchers developed a GNSS receiver and set up an experiment in the Balaeric Islands to collect signals from the receiver that were reflected off the sea surface. Ultimately, these signals will provide improved measurements of the shape of the sea surface.

Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA’s Goddard Space Flight Center</a> describes how scientists are using autonomous sound sensors to monitor deforestation in the Amazon. By recording soundscapes, the experts can determine which animals are present through their distinct sounds.&nbsp;



Using this method, sounds can be used as scientific measurements to analyze the effects of deforestation. The researchers will gain a better understanding of how the acoustics of a forest can be used to measure its health.&nbsp;



"From space, parts of the Amazon rainforest that have previously been logged or burned may look lush and green, like a place buzzing with activity and full of sounds. But inside the rainforest, the animal life may tell a different story, of a harsh environment and a quieter soundscape," says NASA.
