Consciousness has long intrigued thinkers, from ancient philosophers to contemporary neuroscientists. It is a complex phenomenon we encounter daily, yet we often find it difficult to fully define or comprehend.



This elusive aspect of our existence encompasses our thoughts, emotions, perceptions, and self-awareness. 



Despite significant advancements in fields like cognitive science and psychology, the true nature of consciousness remains one of humanity's <a href="https://www.earth.com/news/panpsychism-what-if-all-things-humans-plants-atoms-have-universal-consciousness/" target="_blank" rel="noreferrer noopener">most profound mysteries</a>.



Researchers are actively investigating how consciousness emerges from brain activity, the distinctions between conscious and unconscious states, and the broader implications of consciousness on our understanding of reality and existence.



<h2 class="wp-block-heading" id="h-hyperdimensional-paradigm">Hyperdimensional paradigm</h2>



Michael Pravica, a physics professor at the <a href="https://www.unr.edu/" target="_blank" rel="noreferrer noopener">University of Nevada</a>, offers a fresh perspective on the age-old mystery of consciousness. 



He proposes that understanding this <a href="https://www.earth.com/news/understanding-human-consciousness-through-eureka-moments/" target="_blank" rel="noreferrer noopener">complex phenomenon</a> may require us to look beyond our familiar dimensions.



Central to his theory is the concept of hyperdimensionality -- the intriguing possibility that our universe harbors more dimensions than the four we can perceive (three spatial dimensions and one of time).



Could this expanded view open new pathways for exploring the nature of consciousness? 



By examining these <a href="https://www.earth.com/news/where-in-the-brain-does-consciousness-reside-scientists-think-they-might-know/" target="_blank" rel="noreferrer noopener">broader dimensions</a>, we may uncover insights that have significant implications for our understanding of the universe and our place within it.



"The sheer fact we can conceive of higher dimensions than four within our mind, within our mathematics, is a gift... It's something that transcends biology," Pravica told Popular Mechanics. 



He believes that our ability to imagine and mathematically describe dimensions beyond <a href="https://www.earth.com/news/when-do-babies-start-gaining-their-consciousness/" target="_blank" rel="noreferrer noopener">our physical experience</a> hints at a deeper connection between consciousness and the fabric of the universe.



<h2 class="wp-block-heading" id="h-string-theory-and-higher-dimensions">String theory and higher dimensions</h2>



String theory is an ambitious framework in physics that seeks to unify all fundamental forces and particles into a <a href="https://www.earth.com/news/radical-new-theory-finally-unites-gravity-spacetime-and-the-quantum-realm/" target="_blank" rel="noreferrer noopener">single theoretical model</a>. It proposes that the basic building blocks of the universe aren't point-like particles but tiny, one-dimensional "strings" that vibrate at specific frequencies. 



These vibrations correspond to different particles, much like how different musical notes come from vibrations of a guitar string. To make the mathematics of string theory work, scientists have found that it requires additional spatial dimensions. 



These new dimensions extend beyond the three we experience daily. In some versions of the theory, there are up to ten or eleven dimensions in total.



The extra dimensions aren't easily observed because they might be compactified or curled up at scales so small they're beyond our current ability to detect. Imagine dimensions folded in on themselves like tiny loops at every point in space. 



<h2 class="wp-block-heading" id="h-dimension-of-consciousness">Dimension of consciousness</h2>



While the concepts of hyperdimensionality and string theory have received overwhelming acceptance from physicists, attributing a link between higher dimensions and consciousness can stir up a tempest in the <a href="https://www.earth.com/news/meditation-reveals-common-altered-states-of-consciousness/" target="_blank" rel="noreferrer noopener">scientific teapot</a>.



Interestingly, Pravica, an Orthodox Christian with a PhD from <a href="https://www.harvard.edu" target="_blank" rel="noreferrer noopener">Harvard</a>, harnesses hyperdimensionality to bridge the gap between his scientific understanding and religious faith. He posits a fascinating theory: Jesus could be a hyperdimensional entity.



Pravica explained his perspective by citing a Biblical event. "According to the Bible, Jesus ascended into heaven 40 days after being on Earth. How do you ascend into heaven if you're a four-dimensional creature?" he pondered.



<h2 class="wp-block-heading" id="h-science-fiction-or-fact">Science fiction or fact?</h2>



Not everyone in the scientific field is convinced by Pravica's approach. Some argue that linking consciousness to hyperdimensionality -- and by extension, to religious concepts -- blurs the line between empirical science and personal belief. 



One scientist commented that such theories are bordering "on science fiction." <a href="https://www.fordham.edu/academics/departments/physics-and-engineering-physics/faculty-and-staff/stephen-holler/" target="_blank" rel="noreferrer noopener">Stephen Holler</a>, an associate professor of physics at <a href="https://www.fordham.edu" target="_blank" rel="noreferrer noopener">Fordham University</a> in New York, shares this skepticism. 



He emphasizes the importance of acknowledging gaps in our scientific knowledge without resorting to non-scientific explanations. 



"Gaps in scientific knowledge are attributed to divine intervention, rather than being seen as opportunities for further inquiry and understanding," Holler told Popular Mechanics.



He further expresses concern that this approach might <a href="https://www.earth.com/news/quantum-consciousness-and-you-what-happens-when-machines-become-sentient/" target="_blank" rel="noreferrer noopener">hinder scientific progress</a>. "It's a poor explanation mechanism that arguably stifles the inquisitive nature required for good science and teaches that it’s not okay to say, 'I don’t know'," Holler added. 



His viewpoint highlights the delicate balance between remaining open to new ideas and maintaining rigorous scientific standards.



<h2 class="wp-block-heading" id="h-dimension-of-consciousness-0">Dimension of consciousness</h2>



The debate sparked by Pravica's theory brings to light the broader conversation about how we explore consciousness. Could considering extra dimensions <a href="https://www.earth.com/news/mindfulness-can-lead-to-altered-states-of-consciousness/" target="_blank" rel="noreferrer noopener">offer new insights</a>, or does it complicate the matter further? 



While hyperdimensionality is a well-established concept in theoretical physics, its application to consciousness is relatively uncharted territory.



This discussion also touches on how personal beliefs can influence scientific exploration. Throughout history, many scientists have drawn inspiration from their philosophical or religious views. 



The key challenge lies in ensuring that such influences encourage curiosity rather than limit it.



<h2 class="wp-block-heading" id="h-future-of-consciousness-research">Future of consciousness research</h2>



As we continue to investigate the nature of consciousness, it's essential to keep an open mind while adhering to scientific principles. 



Theories like Pravica's invite us to think creatively and consider possibilities beyond conventional wisdom. They remind us that much about the human mind -- and the universe -- remains unknown.



Advancements in technology, such as <a href="https://www.earth.com/news/quantum-connection-behind-brain-signals-and-human-consciousness/" target="_blank" rel="noreferrer noopener">quantum computing</a> and <a href="https://www.earth.com/news/ai-will-outsmart-humans-when-we-crack-the-neural-code/" target="_blank" rel="noreferrer noopener">artificial intelligence</a>, may soon provide new tools to study consciousness. 



These developments could help us understand how cognitive processes might interact with dimensions we have yet to explore fully.



The quest to comprehend consciousness is far from over. Ideas that challenge the status quo, like the hyperdimensional paradigm, play a crucial role in pushing the boundaries of knowledge. 



Whether or not such theories withstand scientific scrutiny, they provoke valuable discussions that drive progress.

Consciousness may stem from unseen dimensions beyond our reality

It is a complex phenomenon we encounter daily, yet we often find it difficult to fully define or comprehend. This elusive aspect of our existence encompasses our thoughts, emotions, perceptions, and self-awareness.

Renewable Energy Hits Record Pace In 2015. The growth of renewable energy outpaced that of fossil fuels in the electricity sector last year, with a record 135 gigawatts of capacity added from wind, solar, hydropower and other natural sources, a new study shows.
That's more than the generating capacity of all nuclear reactors in the United States and slightly less than Germany's installed capacity from all power sources.
The annual report released early Thursday in Europe by Paris-based REN21, a nonprofit group that promotes renewable energy, underscored how <a href="https://www.bing.com/search?q=china&amp;cvid=d2bb8bdb545145b0b8e00b7cf6e64afd&amp;FORM=ANAB01&amp;PC=HCTS">China</a>, the world's top consumer of coal, has become a global leader in clean energy, too. Renewable Energy Hits Record Pace In 2015
It also highlighted that while renewables now account for 28 percent of the world's electricity-generating capacity, they still account for only a tiny share of how we heat and cool buildings and fuel our means of transportation.
"The share of renewables in the power sector will continue to grow. We see that already, especially in emerging economies," said Christine Lins, executive secretary of REN21. "But we need attention to the heating-cooling sector and transport."
Renewable energy's share in all forms of energy consumption - currently about 10 percent - will have to increase dramatically to fulfill the vision that President Barack Obama and other leaders of the Group of Seven wealthy economies endorsed last week. To fight climate change, they called for deep cuts in heat-trapping carbon emissions and all but eliminating them by the end of the century.
Meanwhile, global energy production must surge to meet the demands of developing economies and a growing world population. The fossil fuel industry and many energy experts say that can't happen without fossil fuels, even in the electricity sector, where coal remains the top fuel.
"Renewables will grow but that doesn't mean coal is going away," said Benjamin Sporton, head of the World Coal Association.
Sporton said India is commissioning 20GW of coal-fired power generation every year. "And they have a further 118GW under construction or approved," he added.
Supporters of renewable energy say the world is already "decoupling" carbon emissions from economic growth, pointing to preliminary data from the International Energy Agency showing that carbon emissions from the energy sector didn't rise last year even though the global economy grew by 3 percent.
However, earlier this week the IEA said that, among other measures, investments in renewables need to increase from $270 billion last year to $400 billion in 2030 to support a transition to a low-carbon economy.
Paolo Frankl, the head of IEA's Renewable Energy Division, said REN21's figures matched research by his own agency, confirming a clear upward trend in renewables.
The REN21 report said renewables accounted for almost 60 percent of the global power capacity added in 2014. Wind power made the biggest jump among the renewables in 2014, with 51GW of new capacity, almost half of it in China.
"This shows that countries are turning towards clean energy to meet their energy needs, rather than fossil fuels that are driving climate change," said Jake Schmidt of the Natural Resource Defense Council, a U.S. environmental advocacy group.
Solar power also expanded, but from a low level; it accounts for only 1 percent of global electricity production.
Geothermal power added just 700MW of capacity, half of it in <a href="http://www.earth.com/news/tiny-monkey-species-kenya/">Kenya</a>. Other renewable sources, such as ocean energy from tidal forces, are not yet having any significant impact.
In heating and cooling of buildings and industry, which accounts for about half of global energy consumption, there was little change from the year before, with renewables representing about 8 percent, mostly biomass.
In the transport sector, dominated by oil-based fuels, the impact of renewables remained small despite growth in biofuels. In road transport their share was only 3.5 percent in 2014, up from 2 percent in 2007, Lins said. As fuel for jets, renewables are still in the experimental stage.
The report said at least 164 countries have set targets for renewable energy and about 145 had policies in place to support it. The authors called for governments to increase support for renewable energy, particularly in the heating and cooling sector.

Congressional Republicans Unmoved by Pope Francis' Climate Message. Pope Francis' call for dramatic action on climate change drew a round of shrugs from congressional Republicans, while a number of the party's presidential candidates ignored it entirely.
"I don't want to be disrespectful, but I don't consider him an expert on environmental issues," said <a href="http://www.earth.com/video/earth-from-space-houston-texas/">Texas</a> Rep. Joe Barton, a senior Republican on the Energy and Commerce Committee, in a comment echoed by others in his party. Congressional Republicans Unmoved by Pope Francis' Climate Message
Even Capitol Hill's Catholic Republicans, despite their religion's reverence for the holy father, seemed unmoved by his urgent plea to save the planet. The reactions suggested that the pontiff's desire to translate his climate views into real action to combat greenhouse gases could fall flat, at least as far as the American political system is concerned.
House Speaker John Boehner, R-Ohio, a Catholic who invited the pontiff to address Congress later this year, said the pope is not afraid to challenge thinking on various issues. "I respect his right to speak out on these important issues," Boehner said, but he demurred when asked whether Francis' views, made public in an encyclical released Thursday, might spur legislative action by the Republicans who run Congress.
"There's a lot of bills out there. I'm not sure where in the process these bills may be," Boehner said.
In the encyclical, a landmark foray by the <a href="https://www.bing.com/search?q=Vatican&amp;cvid=8ebdf6156b3a41939623c03c74f1b224&amp;FORM=ANAB01&amp;PC=HCTS">Vatican</a> into the area of environmental policy, Francis called for a bold cultural revolution, framing climate change as an urgent moral issue and blaming global warming on an unfair, fossil fuel-based industrial model that harms the poor most. He urged people of every faith to save God's creation for future generations.
Francis is to address lawmakers in September in the first speech by a pope to Congress.
Francis enjoyed a 70 percent popularity rating in a poll by the Pew Research Center earlier this year; Congress, by contrast, routinely polls in the teens.
Yet despite his status as an exalted spiritual figure and leader of the world's 1.2 billion Catholics, his pronouncements on climate were received much as a presidential address might be: with enthusiastic embraces from those who already agreed with him, and disavowals or silence from most everyone else.
President Barack Obama fell into the former category. "I welcome His Holiness Pope Francis's encyclical, and deeply admire the pope's decision to make the case - clearly, powerfully, and with the full moral authority of his position - for action on global climate change," the president said in a statement.
The Republicans vying to replace Obama were not so full-throated. A number of them, including Sens. Ted Cruz of Texas and Rand Paul of Kentucky, did not respond to requests for comment or avoided answering when questioned by reporters on the topic.
Former Florida Gov. Jeb Bush questioned the pope's foray into climate science when discussing the issue Wednesday ahead of the encyclical's release.
"I don't think we should politicize our faith," he said.
A statement from a spokesman for former Texas Gov. Rick Perry did not directly mention Francis but said, "Gov. Perry believes the climate is always changing, but it's not clear what role humans have in it."
And an aide to Florida Sen. Marco Rubio directed reporters to comments Rubio made earlier this year seeming to question the pope's decision to weigh in on Cuba.
Rubio and Bush, who converted, both are Catholics, as are several other GOP White House hopefuls. Catholics also are overrepresented on Capitol Hill, accounting for about 30 percent of members of Congress, compared with 22 percent of American adults, according to Pew.
It's not the first time the Catholic Church's teachings on political or social issues have created complications for Catholic lawmakers who take a different view. House Democratic leader Nancy Pelosi of California, who is Catholic, faced questions in the run-up to passage of Obama's health care bill over her support for abortion rights in light of the church's opposition.
But with his entry into the contentious politics of climate, and his attempt to reframe the issue in moral terms, Francis opened a new chapter in the long-running debate over the intersection of politics and religion.
And it was one that most Republicans did not particularly welcome.
"I think the pope needs to continue to study this," said Sen. Jeff Sessions, R-Ala. "I think it will be given respectful treatment, but I don't think it's going to change a lot of votes."

Clean Energy Campaign Launched by Leonardo DiCaprio and Mark Ruffalo. Leonardo DiCaprio and Mark Ruffalo have teamed up in a bid to widen access to clean energy.
The movie stars launched "100%," a campaign aimed at making energy from renewable sources available to everyone - and making it affordable.
DiCaprio has spent much of the last few years toward environmental and animal conservation efforts. At Thursday night's event, the actor said the clean energy movement was no longer about politics, but humanity. Clean Energy Campaign Launched by Leonardo DiCaprio and Mark Ruffalo
"This is a grassroots people's movement but the ambition of this movement is absolutely revolutionary. <a href="https://www.bing.com/search?q=clean+energy&amp;cvid=4ebf9dd5833d4b4ba28a90f952ed6e72&amp;FORM=ANAB01&amp;PC=HCTS">Clean energy</a> grows local economies," he told the crowd.
The event was held at a community garden in <a href="http://www.earth.com/video/earth-from-space-new-york-city/">New York City</a>. Musicians and dancers entertained the crowd while a solar-powered pizza truck provided food. A solar powered cell phone charging station was also available.
Ruffalo - a co-founder of the campaign - called it a "serious issue."
"This is really mankind's greatest threat, and it should take some serious problem solving on all of our parts," he said. "And we don't really have to give up anything to do it. .... We will be collecting the sun and the wind that falls on us every single day."
But he also provided a little good-natured trash talking about New York state's clean efforts versus that of California.
"I just came in from Los Angeles, where I was doing some press and they think they've got something on us concerning renewable energy ... they've got nothing on us. We are coming for you Governor (Jerry) Brown."
This event comes on the heels of Pope Francis' urgent plea on Thursday for the world to clean up the environment, likening it to a moral issue.

Global Warming Won't Reduce Winter Deaths. A study by researchers at Columbia University's Mailman School of Public Health debunks the assumption that global warming will lead to a decline in the number of deaths in winter. Findings by Professor Patrick Kinney, ScD, professor of Environmental Health Sciences and director of the School's Climate and Health Program, showed that a warming climate trend led to much smaller reductions in cold-related mortality than some experts have anticipated. Among 39 cities in the U.S. and France, there was no evidence that cities having warming temperatures experienced any less winter mortality than did cooler cities.

"Some have claimed that warmer winters due to climate change will lead to big reductions in winter deaths. Our work suggests that this is unlikely to be the case," said Dr. Kinney, who was a lead author on the recent report from the Intergovernmental Panel on Climate Change and also serves on the New York City Panel on Climate Change.

If cold temperatures were directly responsible for winter mortality rates, then we would expect future warming to lead to substantial reductions in winter mortality, according to Dr. Kinney. On the other hand, "climate warming would have little benefit if seasonal factors other than temperature are mainly responsible for winter excess mortality," he noted.

To determine whether and to what extent cold temperatures affect excess winter mortality, Dr. Kinney and colleagues analyzed temperature and mortality data from 36 U.S. cities and Paris, Lyon, and Marseille in France. Mortality rates were obtained from the U.S. National Center for Health Statistics and the French National Institute for Statistics and Economics Studies for the period 1971-2007. Findings showed that cities with warmer winters have similar rates of winter deaths compared to their colder winter-counterparts and that there was little relationship evident between mortality and cold temperatures.

"These cities vary widely in demography, urban design, and socio-cultural background, all of which might influence exposure to outdoor temperature and related mortality risks," said Dr. Kinney.

The lack of correlation between seasonal temperature differences and winter season excess mortality suggests that other seasonal factors are driving winter excess mortality including lack of exercise, low humidity and time spent indoors which may lead to increased risk of flu and other respiratory infections and its complications.

The Weather Channel Prioritizes Climate Change Action. The Weather Channel is looking beyond cold fronts and summer showers with a project featuring the voices of 25 prominent people talking about the need to take action on climate change.
The network says its "The Climate 25" series is about science, not politics. But its message is unmistakable, and is consciously designed to reach people who may be doubters about the causes of global warming.
U.S. Army Gen. Charles Jacoby, Unilever CEO Paul Polman, former Environmental Protection Agency administrator Christine Todd Whitman and former Treasury Secretary Hank Paulson are among the participants. The 25 are filmed in black-and-white speaking directly to the camera about their perspectives on climate change.
Polman, for example, talks about his company losing business because of hurricanes, and drought in Africa hurting production at its tea plantations. Jacoby discusses military rescue efforts following extreme storms and how climate change could become a national security issue with nations fighting over resources. Paulson said that doing nothing about climate change is a radical risk.
The project, which started last week, is focused on The Weather Channel's website with occasional features on the television network. Some of the planned TV airings were delayed because of storm coverage from Texas, and the network is considering doing more, said Neil Katz, vice president of digital content.
He said the issue has been a priority for the company for several years. The network issued a statement last year saying "the more the planet warms, the fewer winners and the more losers there will be as the result of the changes in <a href="http://www.earth.com/news/mangrove-forests-in-oman-were-wiped-out-by-climate-change/">climate.</a>"
"We felt there was a climate conversation to be had and with us as a trusted source of weather news, this was a good place to do it," Katz said.
Several conservatives were intentionally chosen to be participants "because we wanted everyone to be part of the conversation," he said.
That's an important strategic move, said Anthony Leiserowitz, director of the Yale Project on Climate Change Communication. People skeptical or less knowledgeable about climate change might be turned off by messages from Greenpeace or Al Gore, but be more attentive to business or military leaders they respect, he said.
The "Climate 25" series is an important educational effort because discussion of the issue is limited in the media and the physical evidence of the problem is not very visible on a day-to-day basis, Leiserowitz said.
"Just getting climate change as an issue in front of people is more than half of the problem right now," he said.
John Coleman, a former TV meteorologist and a co-founder of The Weather Channel, is a widely quoted climate change skeptic and claimed there are others like him who work now at the network who are afraid to speak up because it would cost them their jobs. The Weather Channel Prioritizes Climate Change Action
"They certainly have the right to have an editorial perspective," Coleman said. "I feel it's stupid, scientifically wrong and it's a great disservice. But there is freedom of speech."
Katz noted that while Coleman played an important role in The Weather Channel's start, he's had nothing to do with the station in several decades.

Large Quantities of Nitrous Oxide Found in Southeast Pacific. Originally it became famous as an anesthetic gas used by dentists. However, laughing gas, or chemically correct nitrous oxide, is also found in large quantities in nature and has serious effects on climate: In the lower atmosphere it is a strong greenhouse gas, and in higher layers of the atmosphere it contributes indirectly to the destruction of ozone. "A global assessment of marine nitrous oxide emissions is, however, difficult because we do not know exactly where and how much nitrous oxide is produced," says marine chemist Damian L. Arévalo-Martínez from GEOMAR Helmholtz Centre for Ocean Research Kiel. Together with colleagues from GEOMAR and the University of Kiel (CAU), he presents new data in the international scientific journal Nature Geoscience, showing that the <a href="http://www.earth.com/image/lituya-bay-on-the-southeastern-coast-of-alaska/">Southeast</a> Pacific has been significantly underestimated as a source of nitrous oxide. Large Quantities of Nitrous Oxide Found in Southeast Pacific

The published data are based on three expeditions of the German research vessel METEOR, which took place off Peru between November 2012 and March 2013. Together, the Kiel-based collaborative research centre "SFB 754" and the SOPRAN project have studied the extensive oxygen minimum zone (OMZ) off Peru since 2008. "In that area, like on the eastern boundaries of other tropical oceans, nutrient-rich waters from deeper water layers are transported to the surface," explains co-author Prof. Dr. Hermann Bange, also from GEOMAR. This results in intense plankton growth close to the surface, which upon death, sinks on the water column.

When microorganisms decompose this biomass, they thereby consume more oxygen than can be supplied by surrounding waters and thus the oxygen concentration decreases. Of all the tropical OMZs the one in the <a href="https://www.bing.com/search?q=pacific&amp;cvid=211f7afc86c345b5b835ee5027493005&amp;FORM=ANAB01&amp;PC=HCTS">Pacific</a> is the largest. "We know that oxygen depletion also affects the nitrogen cycle and favors the production of nitrous oxide," says Damian L. Arévalo-Martínez. However, previous measurements allowed only rough estimations of its release to the atmosphere.

During the expeditions in 2012 and 2013, the researchers were able to measure nitrous oxide concentrations continuously from the METEOR for the first time. "Before, the ship had to stop every few miles. We took seawater samples, analyzed them and had data for one point only," explains Professor Bange. He adds: "With the new continuous measurement method we get a lot more data, which also enable us to make better extrapolations for the whole area."

These new data include, among others, the highest ever measured nitrous oxide concentrations in marine surface waters. "Our estimates revealed that each year about 0.3 to 1.4 megatons of nitrous oxide are emitted to the atmosphere from the oxygen minimum zone in the tropical Southeast Pacific. This is up to a fifth of the estimated marine nitrous oxide emissions worldwide and significantly exceeds similar upwelling areas in other tropical oceans," says Arévalo-Martínez.

The investigation of greenhouse gas emissions, such as nitrous oxide, is also important to anticipate future changes in time and to assess their impact on climate. "The OMZs have expanded in recent years, but before we can see an increase or decrease of greenhouse gas emissions, we need to know the actual state," says Professor Bange.

Top Doctors Urge the Earth to Cut out Coal. Some top international doctors and public health experts have issued an urgent prescription for a feverish planet Earth: Get off coal as soon as possible.
Substituting cleaner energy worldwide for coal will reduce air pollution and give Earth a better chance at avoiding dangerous climate change, recommended a global health commission organized by the prestigious <a href="http://www.earth.com/news/new-species-of-sea-sponge-discovered-in-british-columbia/">British</a> medical journal Lancet. The panel said hundreds of thousands of lives each year are at stake and global warming "threatens to undermine the last half century of gains in development and global health." Top Doctors Urge the Earth to Cut out Coal
It's like a cigarette smoker with lung problems: Doctors can treat the disease, but the first thing that has to be done is to get the patient to stop smoking, or in this case get off coal in the next five years, commission officials said in interviews.
"The prescription for patient Earth is that we've got a limited amount of time to fix things," said commission co-chairman Dr. Anthony Costello, a pediatrician and director of the Global Health Institute at the University College of<a href="https://www.bing.com/search?q=london&amp;cvid=96ae517bb0df4e8396197a3a9ccc2dc9&amp;FORM=ANAB01&amp;PC=HCTS"> London.</a> "We've got a real challenge particularly with carbon pollution."
He called it a "medical emergency" that could eventually dwarf the deadly toll of HIV in the 1980s. He and others said burning coal does more than warm the Earth, but causes even more deaths from other types of air pollution that hurt people's breathing and hearts.
Unlike its earlier report in 2009, which laid out the health problems of climate change, this report was more about what can be done to improve the planet's health. It calls for cutting air pollution, more walking and cycling and less driving, better urban design, putting a price on the cost of each ton of carbon being used, improved health care planning for extreme weather and every two year check-ups on how the world is doing to get healthier.
"Virtually everything that you want to do to tackle climate change has health benefits," Costello said. "We're going to cut heart attacks, strokes, diabetes."
The Lancet commission report came out days after an impassioned plea to fight global warming by Pope Francis and hours after the President Barack Obama's administration issued a report emphasizing the costs of inaction on climate change and the benefits of doing something now. The Obama administration said if nothing is done, at the turn of the next century about 57,000 Americans will die each year from polluted air and at least another 12,000 yearly from extreme temperatures.
"Obama is not a doctor; people trust doctors more," Costello said.
In a companion posting in Lancet, World Health Organization director general Margaret Chan also compares fighting climate change to fighting smoking and saving lives. Both Chan and the Lancet commission quote WHO studies that say by 2030 climate change would "be likely to cause about 250,000 additional deaths per year" around the world.
Poverty is the main problem and burning coal to produce electricity helps fight that, said National Mining Association spokesman Luke Popovich. He said, "it makes far more sense to support the technologies that make coal cleaner to use than to support policies that would deny its use to those who rightfully want the comforts of civilization."
But Harvard School of Public Health epidemiologist Joel Schwartz called the Lancet study's coal phase-out "a reasonable prescription for planet Earth. Burning coal has terrible health effects, is bad for global warming and it is destructive of the ecosystem."

More Solar Storms Expected to Bombard Earth. The sizable solar storm that reached Earth on Monday continues to pepper the planet's magnetic field, and forecasters say they have the potential to disrupt power grids and GPS systems.

Image by NOAA Space Weather Prediction Center[/caption]

And there are more on the way, meaning stargazers will have a few days to catch a glimpse of the aurora borealis (or northern lights).

"Solar wind conditions remain highly favorable for continued Strong Geomagnetic storming, with both fast solar wind and strong magnetic fields," NOAA officials <a class="tpstyle" href="http://www.swpc.noaa.gov/news/geomagnetic-storming-reaches-g4-severe-levels" target="_blank" rel="noopener noreferrer">wrote in a forecast update</a>. "Aurora watchers in North America, especially northern tier states of the US, should stay alert."

The storm's solar winds -- buoyed by a solar flare released Sunday -- have continued to bombard <a href="https://www.bing.com/search?q=earth&amp;cvid=39aa78650a5c4da1a3365d9f7e8307fd&amp;FORM=ANAB01&amp;PC=HCTS">Earth</a>, leading officials at NOAA's Space Weather Prediction Center to categorize the storm as a G4 level, or severe, geomagnetic storm.

<a href="http://cff1.greenatom.net/uploads/2015/06/Scott-Kelley-solar-flare_NASA.jpg"><img class="alignleft size-medium wp-image-2382449" src="http://cff1.greenatom.net/uploads/2015/06/Scott-Kelley-solar-flare_NASA-271x300.jpg" alt="Scott-Kelley-solar-flare_NASA" width="271" height="300" /></a>The unusually intense aurora was seen Monday from space as the storm first arrived. NASA astronaut <a class="tpstyle" title="Scott Kelly" href="http://www.upi.com/topic/Scott_Kelly/">Scott Kelly</a>, currently aboard the International<a href="http://www.earth.com/video/happy-4th-from-the-international-space-station/"> Space Station</a>, posted a series of photos showcasing the glowing interactions between solar radiation and Earth's magnetic field.

The most intense solar storms tend to be red, with less intense winds resulting in blues and greens.

As of Tuesday, no significant communications disruptions had been reported. It's likely local power grids have witnessed minor current fluctuations as a result of the radiation, but modern electrical systems are designed to withstand such circumstances.

Another flare was launched from the solar surface on Monday, sending out another wave of radiation. Those storming solar winds are expected to arrive late Wednesday and last through Thursday.

"This timing bodes well for aurora watchers in North America," SWPC forecasters <a class="tpstyle" href="http://www.swpc.noaa.gov/news/another-storm-forecast-wednesday-nightthursday" target="_blank" rel="noopener noreferrer">wrote in a recent update</a>.

Tacolaban, il disastro dopo il tifone nelle Filippine

Climate Change Increases Poverty in Asia-Pacific. Climate change has been making the poor in the Asia-Pacific region even poorer and is also setting back efforts to haul them out of poverty, the Asian Development Bank said in a report Wednesday.
Combined with rising inequality, the two forces could make the more equal distribution of the fruits of <a href="http://www.earth.com/news/new-model-predicts-economically-important-traits-in-crops/">economic</a> growth a "distant goal" for the world's most populous region, where 700 million people - two thirds of the world's poor - still wallow in poverty.
"In one country after another, climate change frequently threatens to offset decades of gains in poverty reduction," the report said. Climate Change Increases Poverty in Asia-Pacific
The report by the Manila-based lender says 1.5 million Filipinos have been pushed deeper into poverty and about 6 million lost their jobs in 2013, as a result of Typhoon Haiyan, one of the world's most powerful storms.
Rising inequality exacerbated by climate change risks from extreme weather also slowed poverty reduction efforts in Indonesia. If inequality and environmental factors had remained constant, the poverty rate would not have risen from 3.6 percent in 2010 to 11.3 percent in 2014, said ADB evaluation specialist Hyun Son.
"Environmental shocks push the poor into direr straits. Hence, responding to climate change helps to reduce inequality," said Vinod Thomas, head of the bank's Independent Evaluation Department, which published the report.
Haiyan, which devastated the central Philippines, drove more Filipinos into extreme hardship of living on less than $1.25 a day. Those who lost their jobs were mostly retailers, service crew, coconut farmers and fishermen. They now are even more exposed to greater hardships from another extreme weather event, the report said.
For a country like Indonesia, whose urban population is expected to rise to 65 percent of the entire nation by 2025 from 50 percent currently, there likely will be a rise in "urban deprivation" that will cause overcrowding and reduction in resources. This will strain public services, resulting in job and income losses as well as environmental shocks for the poor, the report said.
It said building "climate-resilient" infrastructure will help ensure that people, especially the poor, continue to have access to health facilities and market when disasters strike.
Such infrastructure is also crucial in other disaster-prone countries like Tajikistan in Central Asia, which is mostly mountainous, and Papua New Guinea, an island nation. However, climate change and its risks aren't viewed as an urgent development issue by their governments, the report said.
Social safety nets like cash transfers conditioned on improvements in health and education can also help mitigate the impact of climate change on the poor.
In Vietnam, the report said that such measures should be utilized for ethnic minorities who live in remote mountainous areas where people will be further cut off from basic services in case of a major calamity.

Study: Illegal Pot Growing is Hurting the Environment. Illegal pot growers are hurting the environment in California. According to a new study by researchers at the University of California, Berkeley, marijuana farmers are poisoning local food chains and wastefully diverting previous water.

The blame doesn't fall on legal growers with legitimate growing operations; instead, the ecological damage is being done by farmers who stealthily cultivate crops on parklands and on unmonitored rural properties -- typically in remote forested watersheds.

In monitoring the Northern California's Eel River watershed, researchers found illegal pot growing operation using networks of pipes and hoses to siphon water from streams already diminished by drought.

In addition to robbing what little water there is for wildlife and plants, farmers are also polluting the wilderness with pesticides and poison to keep rodents away from their plants. Toxins in the poisoned rats can travel up the food chain, potentially affecting predators like Pacific fishers, a species currently awaiting a ruling on its Endangered Species Act candidacy.

"The environmental harm caused by marijuana cultivation has largely been ignored, but this is a mistake," researcher Stephanie Carlson, a freshwater fish ecologist and an associate professor of environmental sciences at Berkeley, <a class="tpstyle" href="http://news.berkeley.edu/2015/06/24/marijuana-environmental-impact/" target="_blank" rel="noopener noreferrer">explained in a press release</a>.

Carson is one of the authors of a new report on the ecological consequences of marijuana production, published this week <a class="tpstyle" href="http://bioscience.oxfordjournals.org/content/early/2015/06/19/biosci.biv083.abstract?sid=0cdb9909-9da8-421f-9054-e0c311a06347" target="_blank" rel="noopener noreferrer">in the journal Bioscience</a>.

"Marijuana is a thirsty crop that often relies on surface water diversions during California's summer dry season," Carlson said. "While many of our native aquatic organisms are adapted to California's Mediterranean seasonality, the combination of our current drought and summer water diversions for marijuana could be a one-two punch that drives declines in several sensitive populations."

By-the-books pot farmers aren't directly on the hook for the environmental damages detailed in the latest study, but the legalization of medical marijuana has only spurred illicit growing operations.

Making matters worse, scientists say the watersheds most affected are those that are already exceedingly vulnerable -- rivers and streams only recently nursed back to health in the wake of heavy logging.

"The sad fact is that the Eel and coastal rivers like it are on a knife edge," said Mary Power, a professor of integrative <a href="http://www.earth.com/news/compassionate-conservation-animal-welfare/">biology.</a> "All of these wonderful native fishes are on the brink of coming back, and it is very frustrating that their recovery -- which has taken 50 years and is actually a fairly encouraging recovery for the fish and for the older Eel habitat -- is being derailed by the marijuana 'green rush.'"

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.



In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;



According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;



Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. 



Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.



Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians.

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 the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east.

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."

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.”

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

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://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today’s Video of the Day from <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes why experts are studying zebrafish to gain a better understanding of how the immune system responds to injury. Zebrafish have the ability to repair and regenerate organs.



“Organ regeneration offers an exciting opportunity for studying the immune system and to inquire why some species can regenerate organs like the heart or missing limbs while others like humans cannot,” explained Dr. Tatjana Piotrowski.



Zebrafish sensory organ hair cells are an ideal system to investigate the pathways and cell types involved in regeneration since they are easily destroyed with antibiotics and begin regenerating within five hours. This enabled the researchers to identify the exact timing and genetic programs for each anti-inflammatory macrophage activation state.&nbsp;



“Our hypothesis is that human macrophages do not receive the proper chemical activation 'cocktail' to instruct pro-regenerative processes,” said Dr. Nicolas Denans. “Identifying the molecular recipe of macrophage activation in zebrafish may one day enable us to design regenerative immunotherapies in humans.”&nbsp;&nbsp;&nbsp;



“The new evidence is a valuable resource for comparative studies on the genetic programs involved in macrophage-mediated repair and regeneration. In other words, different types of injuries may induce different kinds of inflammatory responses. We want to decipher whether this 'language' is universal or if there are a variety of dialects."

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

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.
