The Met Office has issued a dire warning: global warming is accelerating beyond control, pushing Earth off-track from meeting the 1.5°C (2.7°F) target set in the Paris Agreement. 



The latest data shows a rapid rise in carbon dioxide (CO2) levels and record-breaking temperatures - raising serious concerns about the future of our planet.



Scientists warn that without immediate and drastic action, we are heading toward a climate crisis that will be difficult to reverse.



<h2 class="wp-block-heading" id="h-record-breaking-year-for-global-warming">Record-breaking year for global warming</h2>



The year 2024 officially became the hottest on record, with global average <a href="https://www.earth.com/news/un-the-world-is-on-track-for-a-catastrophic-level-of-global-warming/" target="_blank" rel="noreferrer noopener">temperatures</a> exceeding 1.5°C above pre-industrial levels for the first time. This milestone highlights the increasing intensity of climate change and the urgent need for action. 



<blockquote class="wp-block-quote">
"Last week, it was confirmed that 2024 was the warmest year on record, with annual average temperatures higher than 1.5°C above pre-industrial levels for the first time," stated Professor Richard Betts, who led the <a href="https://www.metoffice.gov.uk" target="_blank" rel="noreferrer noopener">Met Office</a>’s forecast.
</blockquote>



Although this single year does not yet represent a complete failure to meet the Paris Agreement’s target - since long-term warming trends are the true measure of success - scientists warn that this marks a dangerous turning point.



While 2025 may be slightly cooler due to natural climate variations, the overall warming trend will continue unless CO2 emissions decrease dramatically.



The data aligns with findings from the Copernicus Climate Change Service (C3S), which reported that global temperatures in 2024 were 0.12°C (0.22°F) higher than in 2023, the previous record-holding year. This confirms that humanity is now dangerously close to breaching the Paris Agreement’s long-term warming limit.



<h2 class="wp-block-heading" id="h-very-large-rise-in-co2-levels">Very large rise in CO2 levels </h2>



Perhaps even more concerning than <a href="https://www.earth.com/news/2024-confirmed-as-earths-hottest-year-in-recorded-history/" target="_blank" rel="noreferrer noopener">rising temperatures</a> is the unprecedented increase in atmospheric CO2 levels. 



Measurements taken at Mauna Loa, Hawaii, revealed that CO2 concentrations rose by 3.58 parts per million (ppm) in 2024 - the fastest annual increase since records began in 1958. This increase far exceeded the Met Office’s prediction of 2.84 ppm, highlighting that emissions are outpacing even the worst-case scenarios.



Satellite data further confirmed a "very large rise" in CO2 levels globally. This increase is partly attributed to the El Niño phenomenon, which created widespread hot and dry conditions, reducing the ability of forests and ecosystems to absorb CO2. 



However, human activities - particularly the burning of fossil fuels - remain the primary driver of rising <a href="https://www.earth.com/news/rapid-surge-in-global-warming-may-have-an-unexpected-source/" target="_blank" rel="noreferrer noopener">emissions</a> and global warming.



To meet the 1.5°C goal, the Intergovernmental Panel on Climate Change (<a href="https://www.ipcc.ch" target="_blank" rel="noreferrer noopener">IPCC</a>) has stated that CO2 emissions must be reduced by 1.8 ppm per year. Instead, we are seeing an accelerating rise, making it increasingly difficult to stay within safe climate limits.



<h2 class="wp-block-heading" id="h-role-of-natural-climate-patterns">Role of natural climate patterns</h2>



Looking ahead, scientists predict that CO2 levels will continue to rise in 2025, though at a slightly slower rate. 



The Met Office estimates an increase of 2.26 ± 0.56 ppm, which is lower than the extreme rise seen in 2024. This expected decrease is linked to the transition from El Niño to La Niña conditions, which will help ecosystems absorb more CO2.



<blockquote class="wp-block-quote">
"La Niña conditions are expected to cause forests and other ecosystems to soak up more carbon than last year, temporarily slowing the atmospheric CO2 rise," explained Professor Richard Betts.
</blockquote>



While this temporary relief may slightly reduce the speed of warming, it is not nearly enough to counteract the long-term accumulation of greenhouse gases. As Betts warns, stabilizing global temperatures will require emissions to not only stop increasing but to reverse entirely.



<blockquote class="wp-block-quote">
"Stopping global warming needs the build-up of greenhouse gases in the air to come to a complete halt and then start to reduce. Large, rapid emissions cuts could limit the extent to which global <a href="https://www.earth.com/news/ancient-climate-shift-sheds-light-on-future-global-warming/" target="_blank" rel="noreferrer noopener">warming</a> exceeds 1.5°C. But this needs urgent action internationally," said Betts.
</blockquote>



<h2 class="wp-block-heading" id="h-long-term-global-warming-and-temperature-rise">Long-term global warming and temperature rise</h2>



Although natural climate variations like El Niño contribute to short-term temperature fluctuations, scientists overwhelmingly agree that human activities are the main force behind long-term global warming. 



The continued burning of coal, oil, and gas is releasing vast amounts of CO2 into the atmosphere, pushing the planet toward more extreme and unpredictable weather events.



<blockquote class="wp-block-quote">
"This record needs to be a reality check. The climate is heating to levels we've spent years trying to avoid because countries are still burning huge amounts of oil, gas and coal," noted Dr. Friederike Otto, a climate policy expert from <a href="https://www.imperial.ac.uk" target="_blank" rel="noreferrer noopener">Imperial College London</a>.
</blockquote>



This statement highlights the failure of global leaders to take sufficient action to reduce emissions. While renewable energy sources like wind and solar are expanding, they are not replacing fossil fuels quickly enough to prevent further warming.



<h2 class="wp-block-heading" id="h-dire-consequences-of-inaction">Dire consequences of inaction</h2>



If global warming continues at its current pace, the consequences will be severe. 



Rising temperatures contribute to more frequent and intense natural disasters, including heatwaves, wildfires, hurricanes, and flooding. In 2024 alone, extreme weather events linked to climate change caused devastation worldwide.



For example, the ongoing wildfires in Los Angeles serve as a grim reminder of what the future could hold if global temperatures continue to rise unchecked. Higher temperatures dry out vegetation, creating the perfect conditions for large, uncontrollable fires.



The rise of global warming also threatens food security, water supplies, and human health. Crops struggle to grow in extreme heat, while changing weather patterns lead to droughts and flooding.



Additionally, air pollution from fossil fuel combustion contributes to respiratory illnesses and premature deaths.



<h2 class="wp-block-heading" id="h-what-needs-to-happen-now">What needs to happen now?</h2>



Scientists warn that immediate action is necessary to cut greenhouse gas emissions. The shift to renewable energy is happening, but it must accelerate significantly. 



Governments, businesses, and individuals all have a crucial role to play in addressing climate change. Countries must phase out fossil fuels while expanding clean energy sources.



Protecting and restoring forests, wetlands, and oceans will help absorb more CO2. Reducing energy waste in industries, buildings, and transportation can lower emissions. 



Governments must enforce stricter regulations, support sustainable development, and invest in green technology. Public awareness is essential, as people must understand their impact and choose more sustainable lifestyles.



The world is running out of time to prevent catastrophic global <a href="https://www.earth.com/news/co2-has-regulated-earths-climate-for-millions-of-years/" target="_blank" rel="noreferrer noopener">warming</a>. The warnings from scientists are louder than ever, and the evidence is undeniable. The question remains - will humanity rise to the challenge before it’s too late?

Global warming is accelerating beyond control as CO2 levels rise

The Met Office has issued a dire warning: global warming is accelerating beyond control, pushing Earth off-track from meeting the 1.5°C (2.7°F) target set in the Paris Agreement. The latest data shows a rapid rise in carbon dioxide (CO2) levels and record-breaking temperatures - raising serious concerns about the future of our planet.

Scientists are warning that an underwater supervolcano off the coast of Japan may be building toward a massive eruption. The Kikai Caldera, which is submerged just south of Kyushu Island, is responsible for one of the most explosive supereruptions of the last 10,000 years.

Researchers at the <a href="http://www.k-obec.kobe-u.ac.jp/">Kobe Ocean-Bottom Exploration Center</a> (KOBEC) have found evidence that the Kikai volcano is collecting lava in its 6.2-mile-wide dome. 

The giant dome appears to be growing and already contains approximately 7.68 cubic miles of <a href="https://www.earth.com/news/philippines-volcano-spewing-lava/">lava</a>. The KOBEC team confirmed that this dome was created after the volcano’s earth-rumbling eruption 7,300 years ago.

Six of the samples collected at the caldera site since 2015 turned out to be rhyolites, which form during the cooling of lava or magma. In addition, the scientists documented several intrusions on the dome’s surface, indicating the presence of lava.

The experts also observed bubbling gas and superheated water columns in the vicinity. The team made these observations using underwater robots, underwater seismographs, and by collecting and analyzing rock samples.

On their next mission, the scientists will use seismic reflection and underwater robots to explore how the caldera formed and to investigate what leads up to a massive caldera eruption. The researchers will also attempt to capture high resolution images of magma build-up in the Earth’s crust.

Yoshiyuki Tatsumi is a magma specialist at KOBEC and the study's first author. Professor Tatsumi told <a href="https://mainichi.jp/english/">The Mainichi</a> , “Although the probability of a gigantic caldera eruption hitting the Japanese archipelago is 1 percent in the next 100 years, it is estimated that the death toll could rise to approximately 100 million in the worst case scenario.”

Experts fear that the Kikai Caldera could erupt without warning. They say the event could significantly alter the climate, triggering a volcanic winter.

In an effort to speed up the construction of his proposed wall across the Mexican border, <a href="https://www.earth.com/news/trump-cut-clean-energy/">President Trump</a> is waiving over 30 environmental regulations. He has also announced a new infrastructure plan that will make building permits easier to acquire despite any environmental threats that may be posed by the projects.

As he unveiled the White House’s $200 billion dollar infrastructure proposal, President Trump promised to “speed the permit approval process from 10 years to two years, and maybe even to one year.” Trump intends to limit environmental reviews of building projects to 21 months and hopes to restrain federal agencies from objecting to new construction.

Twenty-eight environmental organizations, including the Animal Welfare Institute, issued the following joint statement:

“President Trump’s proposal is an unprecedented giveaway to the wealthy and powerful that would allow his administration and its special interest allies to unilaterally sidestep bedrock conservation, public health, and worker safety laws that keep our families and communities out of harm’s way.”

Conservationists are also outraged that the Trump administration is attempting to evade critically significant policies to construct the border wall including the National Environmental Policy Act, the Endangered Species Act, and the Clean Water Act.

The Department of Homeland Security claims that there is an immediate need for the wall, specifically to stop a large amount of illegal entry in El Paso.

A notice published in the government's Federal Register stated: “The Secretary of Homeland Security has determined, pursuant to law, that it is necessary to waive certain laws, regulations and other legal requirements in order to ensure the expeditious construction of barriers and roads in the vicinity of the international land border of the United States.”

The Center for Biological Diversity is reporting that the border wall threatens the habitats of dozens of species. The nonprofit organization is considering taking legal action against the construction of the wall for the second time.

Researchers at <a href="https://www.rockefeller.edu/">Rockefeller University</a> have quite literally made a groundbreaking discovery. While analyzing soil samples from all over the United States, the experts found a new class of antibiotics that may be capable of killing strains of bacteria which have become drug resistant, or <a href="https://www.earth.com/news/hospital-superbugs-antibiotic-resistant/">superbugs</a>.

Antibiotics and other microbial agents have saved millions of lives over the last 70 years, but the rapid emergence of antibiotic-resistant bacteria has become a global crisis.

According to the <a href="https://www.cdc.gov/">Centers for Disease Control and Prevention</a> (CDC), over 2 million people are infected with antibiotic-resistant bacteria every year in the United States, and at least 23,000 of those infected die as a direct result.

Globally, at least 700,000 people die each year as a result of drug resistance, and that number is predicted to reach 10 million by the year 2050.

Dr. Sean Brady is a researcher and microbiologist at Rockefeller University and lead author of the current study. Dr. Brady and his team set out to investigate the bacteria and microorganisms abundantly found in soil.

“Every place you step, there’s 10,000 bacteria, most of which we’ve never seen,” Dr. Brady told <a href="https://www.washingtonpost.com/">The Washington Post</a>. “Our idea is, there’s this reservoir of antibiotics out in the environment we haven’t accessed yet.”

The researchers used a gene sequencing technique to analyze over 1,000 soil samples contributed by scientists from all over the United States. One sequence contained a gene with a known association to the production of calcium-dependent antibiotics.

The team cloned the DNA and cultured it, and the microorganisms began producing the new antibiotics which were named malacidins. 

The team tested the compounds on rats with methicillin-resistant Staphylococcus aureus (MRSA) and found that the malacidins successfully killed the infections. The team will now investigate whether the antibiotics are safe for humans.

Dr. Brady told the <a href="https://www.bbc.co.uk/">BBC</a>: “It is impossible to say when, or even if, an early stage antibiotic discovery like the malacidins will proceed to the clinic. It is a long, arduous road from the initial discovery of an antibiotic to a clinically used entity.”

The study is published in the journal <a href="https://www.nature.com/nmicrobiol">Nature Microbiology</a>.

Researchers at <a href="https://www.wvu.edu/">West Virginia University</a> are reporting that songbird populations in the central Appalachian Mountains are struggling with a greater presence of shale gas development. An investigation has revealed that the nesting success of the Louisiana Waterthrush, in particular, has declined at sites impacted by the extraction of natural gas.

The most rapid growth of hydraulic fracturing in the country is taking place in northwestern West Virginia. Prior to this study, little was known about how this <a href="https://www.earth.com/news/shale-gas-inefficient-electricity/">shale gas</a> industry boom may be affecting bird populations in the region.

A team of researchers led by Mack Frantz mapped territories of the waterthrush and monitored nests along 14 streams from 2009-2011 and also from 2013-2015. Using aerial photographs and satellite imagery, the experts measured disturbances to both the streams and the forest canopy, and then determined which of these disturbances were caused by shale gas development.

The results of the study showed that nest survival and reproductive success declined as shale gas development expanded. Experts also noted that the size of individual waterthrush territories increased, which indicates that the birds had to range farther in order to access a sufficient amount of resources.

“I hope our findings lead to robust protections of our forested headwater stream ecosystems, which are currently overlooked for regulation despite their critical role in providing nutrients and organic matter downstream, not to mention as an important source for drinking water,” said Frantz. 

“Waterthrushes are a modern-day 'canary in the coal mine,' and there are many more opportunities to study how anthropogenic disturbance affects and entangles food webs at the aquatic-terrestrial interface.”

The study is one of the first to demonstrate that shale gas development can affect songbird reproductive success and productivity. Leesia Marshall is a waterthrush expert who was not involved in the research. 

“This paper should serve as a call for all scientists to redouble efforts across all related disciplines to document the present impacts of shale gas extraction and to develop strategies for mitigation and avoidance of potential impacts in the future,” said Marshall.

The study is published in <a href="http://americanornithologypubs.org/loi/cond">The Condor: Ornithological Applications</a>.

According to a new study from the <a href="https://www.york.ac.uk/">University of York</a>, carefully managed fire can optimize mammal and bird diversity in African savannas. 

The research, which is the first of its kind to examine the “pyrodiversity" of an entire continent, revealed that this strategy can improve the number of mammal species by 20 percent and the number of bird species by 30 percent with adequate rainfall.

“Fire is often viewed as homogeneous, but in reality there is a range of different fires characterized by variation in size, intensity, season and frequency of burning,” said lead author Dr. Colin Beale. “We found that in wet savanna increasing the range of different types of fire in an area allows a wider number of species to thrive.”

“Fire is widely thought to have a negative impact on the environment, but in African savannas hominids have been setting a variety of fires for around a million years so fire is something the ecosystem has co-evolved with and adapted to.”

The researchers gathered 15 years of satellite data on fires and accessed distribution maps of all the bird and mammal species in protected areas across <a href="https://www.earth.com/news/african-savannahs-climate-change/">Africa's savannas</a>. The study revealed that savannas with abundant rainfall and the most varied types of fire contained significantly more bird and mammal diversity.

The experts found that a range of fire types allowed rare species of birds, such as the Rufous-tailed Weaver and the Black-bellied Sunbird, to cohabitate with more common bird species. The study findings indicate that fires alter the conditions within savanna habitats and increase the availability of nutrients, terrain, and shelter for a greater number of species to thrive.

As a result of the investigation, the researchers hope to provide land managers and conservationists with guidance on how to use carefully managed fire as a tool to boost biodiversity.

“Pyrodiversity is particularly important for biodiversity in wet savanna landscapes, but this isn't the only reason people light fires: different goals require different burning patterns,” said Dr. Beale. “We want to develop tools to help the managers of conservation areas articulate what they want to achieve and help them to use fire to do it.”

The study is published today in <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1461-0248">Ecology Letters</a>.

<a href="https://www.earth.com/news/deadly-heatwaves-rise-emission/">Heat stress</a> can have a devastating effect on plant growth and development, and can greatly reduce crop yields. Researchers at the <a href="https://www.cam.ac.uk/">University of Cambridge</a> set out to gain a better understanding of how plants sense and respond to heat stress.

Plants respond to heat differently during the day compared to night time, and plants have a much better chance of survival when they are exposed to heat during the day. This is because they have adapted a cycle of resistance that helps them to endure the hottest hours of the day.

Plants use their sense of temperature to activate the production of protective heat shock proteins (HSP), yet the signaling process involved in this activation process is a mystery. Previous research has indicated that heat resistance is triggered in plants when they are exposed to light and then deactivated in the darkness.

“I was quite interested in how plants respond to their environment and was surprised that there was so much to be learned about how plants sense and respond to temperature,” said study co-author Patrick Dickinson. “There is a lot known about how plant and animal cells respond to extreme heat stress, but not much was known about their response to ambient heat or how they regulate their response to heat between day and night."

Dr. Dickinson found that chloroplast genes are linked to plant stress response. He discovered that the chloroplast sends a signal in response to light, and this signal activates gene expression in the nucleus which protects the plant from heat stress.

“There is some sort of signal coming initially from the photosynthetic electron transport chain, which is communicated to the nucleus to activate the gene expression, but what that signal is is not clear yet,” explained Dr. Dickinson.

“It could possibly be hydrogen peroxide because that has been shown to move from the chloroplast to the nucleus to initiate signalling, but there is still a lot more that needs to be looked at to confirm the nature of the signalling.”

Study supervisor Dr. Phil Wigge stressed the importance of identifying the genes that are involved in the heat resistance of plants.

“Many of the crops being grown around the world today are already being grown at the top of their comfort zone in terms of temperature,” said Dr. Wigge. “There is actually an estimate that for major crops like wheat, rice and maize, that every degree Celsius rise in temperature above current temperatures could potentially decrease crop yields by between 3-7% due to thermal stress.”

“The contribution that we are trying to make in the lab is to understand the molecules and the underlying mechanisms that control how a plant senses temperature and the genes that are required for a plant to adapt to higher temperatures. And we hope that we can then use that information to discover the same genes in crop plants and see if those genes can be used to make crop plants more resilient to heat stress."

The study is published in the journal <a href="http://www.cell.com/cell-reports/home">Cell Reports</a>.

How plants protect themselves from heat stress

Heat stress can have a devastating effect on plant growth...

A new study has found that contrary to many previous climate studies, lightning strikes will occur much less frequently even under the worst case climate change scenarios where temperatures increase by five degrees Celsius by the year 2100. 

Researchers from the Universities of <a href="https://www.ed.ac.uk/">Edinburgh</a>, <a href="http://www.leeds.ac.uk/">Leeds</a>, and <a href="http://www.lancaster.ac.uk/">Lancaster</a> found that many <a href="https://www.earth.com/news/worst-case-climate-unlikely/">climate change</a> studies that project an increase in lightning strikes don’t take into account the decrease in cloud ice. 

Climate change is predicted to increase storms and extreme weather events, cause drought, wildfires, heat waves, and sea level rise as well as habitat degradation and coastal flooding. 

However, in a new study published in the journal Nature Climate Change, the researchers found that decreased cloud ice due to increased temperatures will likely lead to a 15 percent decrease in lightning strikes. 

As tiny ice particles form and move within the clouds, it builds up an electrical charge in the particles. When it rains or storms, the release of the particles causes the electrical charge to create lighting and thunder.

For the study, the researchers created a method that calculated cloud ice and factored in the cloud ice relationship on future lightning strikes under worst-case scenario conditions. 

Fewer lightning strikes mean fewer natural wildfires and damage to power lines and buildings. 

According to the <a href="http://www.dailymail.co.uk/sciencetech/article-5381867/Global-warming-reduce-lightning-strikes.html">Daily Mail</a>, in the US alone lightning strikes cause anywhere between $5 to $6 billion in damage each year.

The results show how worst-case scenarios and climate change projections, while important to understanding the effects of warming temperatures, don’t always consider all the factors that should be accounted for. 

“'In previous studies of the impact of climate change on lightning, researchers often didn't include consideration of changes in cloud ice,” Declan Finney, a member of the researcher team, told <a href="http://www.dailymail.co.uk/sciencetech/article-5381867/Global-warming-reduce-lightning-strikes.html">Daily Mail</a>.  “This research questions the reliability of previous projections of lightning, and encourages further study into the effects of climate change on cloud ice and lightning.”

In an effort to combat <a href="https://www.earth.com/news/china-air-pollution-years/">air pollution</a> and climate change, China is planning to construct the world's first city that is made up of vertical forests. Every building in the Liuzhou Forest City including houses and schools will be covered entirely in plants and trees.

The forest will include almost a million plants of 100 species and tens of thousands of trees. Nearly 10,000 tons of carbon dioxide and 57 tons of pollutants will be absorbed by the massive collection of greenery, while approximately 900 tons of oxygen will be generated.

The city will be north of Liuzhou in a mountainous region of southern China along the Liujiang river. It will cover around 342 acres with over 70 buildings. 

Around 30,000 residents will have electricity provided by solar panels and air conditioning powered by geothermal energy. Forest City will also have a fast rail line that connects to Liuzhou for electric cars.

The green city was designed at <a href="https://www.stefanoboeriarchitetti.net/">Stefano Boeri Architetti</a>, a Milan-based studio of architecture founded by Stefano Boeri. In addition to curbing air pollution, the abundant vegetation is expected to reduce noise pollution, promote cooler temperatures, and improve biodiversity in the region.

Stefano Boeri explained: “For the first time in China and in the world, an innovative urban settlement will combine the challenge for energy self-sufficiency and for the use of renewable energy with the challenge to increase biodiversity and to effectively reduce air pollution in urban areas - which is really critical for present-day China - thanks to the multiplication of vegetable and biological urban surfaces.”

The Liuzhou Municipality Urban Planning Bureau has approved the plan, and construction will begin in the year 2020.

Experts at the <a href="https://www.colorado.edu/">University of Colorado at Boulder</a> are reporting that sea level rise is steadily accelerating every year. The researchers analyzed 25 years of satellite data and estimated that this rate is climbing by about 0.08 mm annually.

“This acceleration, driven mainly by accelerated melting in Greenland and Antarctica, has the potential to double the total sea level rise by 2100 as compared to projections that assume a constant rate--to more than 60 cm instead of about 30,” said lead author Steve Nerem. 

“And this is almost certainly a conservative estimate. Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. Given the large changes we are seeing in the ice sheets today, that's not likely.”

At the current rate, the <a href="https://www.earth.com/news/cities-sea-levels-rise/">sea level</a> would rise 26 inches by the end of the century. Increasing air and ocean temperatures cause land ice to melt, which contributes to sea level rise. In addition, warmer water expands and the researchers found that this thermal expansion is responsible for about half of the global sea-level rise that has occurred over the last 25 years.

Estimating the acceleration of sea level rise is challenging, primarily because the rate can fluctuate as a result of ENSO cycles and volcanic eruptions. For example, the eruption of Mount Pinatubo in 1991 significantly decreased the global mean sea level. The team used climate models to account for these influences.

The experts also used data from the GRACE satellite gravity mission, which revealed that the acceleration is largely being driven by melting ice in Greenland and Antarctica.

“This study highlights the important role that can be played by satellite records in validating climate model projections,” said co-author John Fasullo. “It also demonstrates the importance of climate models in interpreting satellite records, such as in our work where they allow us to estimate the background effects of the 1991 eruption of Mount Pinatubo on global sea level.”

The researchers plan to expand upon this study using a longer time frame. They will also examine regional sea level rise in order to make better predictions on how specific coastal areas will be impacted.

The research is published in the journal <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Sea level rise is steadily accelerating every year

Experts at the University of Colorado at Boulder are reporting...

Researchers at the <a href="https://www.jic.ac.uk/">John Innes Centre</a> in England set out to examine how changing environmental conditions affect seed dispersal in plants. They found that <a href="https://www.earth.com/news/2017-second-hottest-year-2/">rising temperatures</a> will cause many species of crops in the cabbage and mustard family to prematurely release seeds, which is detrimental to the reproductive process.

“In many crops, such as oilseed rape, premature seed dispersal is one of the major causes of crop loss. In the context of climate change, this could become increasingly severe,” explained co-author Vinod Kumar. “This study exposes the potential vulnerabilities of crop production in the warming world and paves the way for addressing this problem.”

Plants adjust their cycles according to a range of environmental conditions. They endure daily changes in weather and temperature, yet remain aligned with the seasons.

“Seed dispersal is also a key trait that must be controlled when domesticating plants for food production,” said co-senior author Lars Ostergaard. “With the prospect of climate change affecting crop performance, we wanted to understand how environmental signals such as temperature affect seed dispersal.”

The team focused its investigation on Arabidopsis plants, which belong to the mustard or cabbage family. When the researchers exposed the plants to temperatures elevated from 22 degrees Celsius to 27 degrees Celsius, they found that the plants opened their seed pods earlier and released seeds.

The experts determined that the rise in temperature had promoted the expression of the INDEHISCENT gene, which is known to regulate the development of seed pod tissue and promote fruit opening.

“We speculate that such mechanisms have evolved to facilitate proper seasonal timing of dispersal to ensure that seeds are released under conditions that are both timely and climatically optimal for germination,” said study first author Xin-Ran Li. “There could perhaps be a selective advantage in early maturation and dispersal in the wild."

The researchers plan to further investigate the mechanisms involved when seed dispersal is altered by elevated temperatures.

“We are hopeful that by understanding this in detail, we will be better equipped to devise strategies to breed for crop resilience to climate change,” said Ostergaard.

The study is published in the journal <a href="http://www.cell.com/molecular-plant/home">Molecular Plant</a>.

These crops will confuse global warming with change of season

Researchers at the John Innes Centre in England set out...

Climatologists rely on future climate projections and emission levels to assess how <a href="https://www.earth.com/news/humans-driving-climate-change/">climate change</a> will impact the globe and what conditions will look like if emissions are not reduced. 

These projections rely on past data from the known climate record and current and future estimates of energy use. The climate scenarios also show a stark and sobering future if more is not done to mitigate climate change and reduce carbon emissions. 

As it stands today, there are four main scenarios that climatologists use for their research. These  scenarios are based on Representative Concentration Pathways, or RCPs, that measure possible concentrations of greenhouse gas emissions.

However, researchers from the <a href="https://www.ubc.ca/">University of British Columbia</a> found that the methods for estimating future climate conditions and emissions are somewhat of an exaggeration and the popular RCPs are inaccurate. 

Instead, we may actually be closer to achieving the mandates set by the Paris Accord than we think. 

RCPs look at emissions from coal, and many climate scenarios are based on coal consumption estimates that are much higher than any realistic measurement. 

According to <a href="https://www.bloomberg.com/news/articles/2018-02-09/climate-change-just-got-a-little-less-terrible">Bloomberg</a>, the most extreme worst case scenario estimates that coal consumption would increase to such an extent that it would account for 94 percent of the world’s energy supply, but in 2015 coal only accounted for 28 percent of the world’s energy supply. 

“Climate change modeling relies on projections of future greenhouse gas emissions and other phenomena leading to changes in planetary radiative forcing,” the researchers write. “However, outlooks for forcing from fossil energy combustion can also be presented and defined in terms of two essential components: total energy use this century and the carbon intensity of that energy.” 

In other words, the researchers outline a method for matching carbon emissions with energy consumption that more accurately depicts future climate projections based on the world’s energy needs. 

The results show that we may be closer to reducing carbon emissions to the levels set by the Paris Accord, which could mean that government policies could implement even stricter emissions standards to continue to combat climate change.

A new study has found that using smart technology in national parks could have many benefits including helping conservation efforts, keeping visitors safe, and cutting emissions from motor traffic. 

Edward Truch and his colleagues from <a href="http://www.lancaster.ac.uk/lums/">Lancaster University Management School</a> were commissioned by the <a href="https://www.gov.uk/government/organisations/lake-district-national-park-authority">Lake District National Park Authority</a> to look into integrating smart technologies into national parks. 

The Lakes District is a collection of scenic lakes in the Northwest regions of England and is a popular tourist destination that offers hiking, boating, and sightseeing opportunities for its many visitors.   

Their report outlined several innovative ways that smart technology could be used in parks. 

Some of the suggestions include having recycling and garbage bins send alerts when they are full to avoid unnecessary garbage collections, monitoring trail conditions and the impacts of climate change with sensors,  and sending alerts to hikers’ phones when they are tired and near a rest stop. 

“National Parks are under increasing pressure to deliver more for less and with population booms, visitor numbers are increasing - putting greater strain on the natural environment,” said Truch. “This report sets out business models and revenue streams for National Parks right across the world to consider, that can help address the gaps in budgets caused by cuts in public sector spending.”

“Smart parks” could bring innovations in safety and conservation. The researchers note that consumers are already making use of apps and websites that can book hotel rooms and help people get around. 

Bringing these technologies into parks would not be a difficult feat and might make parks even more popular and attract new visitors. 

As more and more technologies and products sync up to the internet, and population growth brings more and more traffic to the world’s parks, it only makes sense to have parks integrated with smart technologies. 

Truch’s report offers a solution to the problem many nations are facing where budget cuts often make <a href="https://www.earth.com/news/national-parks-trump-ghost-teddy-roosevelt/">national parks</a> low on the list of priorities.

“The report offers a very new look at how designated natural areas and other green spaces, and the people that visit them, can benefit from the latest innovations in modern technology,” said Chris Mahon, Chief Executive of the International Union for the Conservation of Nature Committee UK and Development Director of World Heritage UK, “It's about new ways of delivering conservation as well as visitor convenience and experience enhancement.”

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.

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.

Today's Video of the Day from the <a href="http://www.esa.int/">European Space Agency</a> features Qeshm Island in the Strait of Hormuz. This strait provides the only sea passage from the Persian Gulf to the open ocean.



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.
