A new phenomenon dubbed "ice piracy" is unfolding in the frigid wilderness of West Antarctica, where one glacier appears to be stealing ice from its neighbor. 



This unusual behavior - once believed to take hundreds or even thousands of years - has now been recorded happening in under two decades.



Scientists from the University of Leeds, working with international collaborators, have used high-resolution satellite data to reveal that a fast-moving glacier is redirecting ice flow away from its slower neighbor.



This surprising event is changing how scientists understand the dynamics of glaciers - and how such shifts may contribute to future sea-level rise. Their findings, now published in The Cryosphere, provide rare insight into these rapid changes.



<h2 class="wp-block-heading" id="h-fast-paced-shift-in-the-ice">Fast-paced shift in the ice</h2>



Between 2005 and 2022, researchers observed that seven <a href="https://www.earth.com/news/ice-streams-move-unpredictably-due-to-hidden-quakes/" target="_blank" rel="noreferrer noopener">ice streams</a> in the Pope, Smith, and Kohler (PSK) region of West Antarctica sped up significantly. 



One glacier nearly doubled its speed - an 87% increase - at the point where it meets the ocean. 



Three other glaciers accelerated by 60% to 84%. By 2022, six of these streams were moving at more than 700 meters (0.4 miles) per year. That’s the equivalent of covering just over seven football fields in just one year.



This kind of acceleration, especially so close to the grounding line - the point where a glacier starts to float - is a warning sign. 



Grounding lines help track the stability of ice sheets. Changes in their position or speed suggest the system is out of balance and can influence how ice flows inland.



<h2 class="wp-block-heading" id="h-slowing-glaciers-leads-to-ice-piracy">Slowing glaciers leads to ice piracy</h2>



But not every glacier followed the same pattern. The Kohler West glacier actually slowed down by 10% during the same time period.

This stood in stark contrast to nearby glaciers like Kohler East and Smith West, which sped up dramatically - by about 560 meters per year.



The slowdown puzzled scientists, until they looked at the ice flow patterns.



<h2 class="wp-block-heading" id="h-kohler-west-and-kohler-east">Kohler West and Kohler East</h2>



“We think that the observed slowdown on Kohler West Glacier is due to the redirection of ice flow towards its neighbor - Kohler East," explained lead author Dr. Heather L. Selley from the <a href="https://www.leeds.ac.uk/" target="_blank" rel="noreferrer noopener">University of Leeds</a>.



"This is due to the large change in Kohler West’s surface slope, likely caused by the vastly different thinning rates on its neighboring <a href="https://www.earth.com/news/antarctic-glaciers-flow-faster-during-the-summer-time/" target="_blank" rel="noreferrer noopener">glaciers</a>.” 



She added that because Kohler East’s ice stream is flowing and thinning faster as it travels, it absorbs, or ‘steals’ ice from Kohler West. 



"This is effectively an act of ‘ice piracy’, where ice flow is redirected from one glacier to another, and the accelerating glacier is essentially ‘thieving’ ice from its slowing neighbor,” explained Selley.



“We didn’t know ice streams could ‘steal’ ice from each over such a short period, so this is a fascinating discovery. It’s unprecedented as we're seeing this from satellite data and it’s happening at a rate of under 18 years, whereas we’ve always thought it was this extremely long, slow process,” she added.



<h2 class="wp-block-heading" id="h-watching-ice-piracy-from-space">Watching ice piracy from space</h2>



To track this shift, the research team used satellite images and a technique that follows the movement of surface features like crevasses and rifts. 



They also incorporated data on ice thinning from the European Space Agency’s <a href="https://www.esa.int/Applications/Observing_the_Earth/FutureEO/CryoSat" target="_blank" rel="noreferrer noopener">CryoSat mission</a>.



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/05/Antarctica_ice-piracy_speed-direction_Crosson-Dotson-Ice-Shelves_2015-2022_ESA_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/05/Antarctica_ice-piracy_speed-direction_Crosson-Dotson-Ice-Shelves_2015-2022_ESA_1s.webp" alt="The image depicts the average speed and direction of multiple glaciers flowing into the Crosson and Dotson Ice Shelves in West Antarctica from 2015 to 2022.

Data was sourced from satellites operated by ESA, NASA, the Canadian Space Agency, and the Japan Aerospace Exploration Agency.



“This study provides an interesting demonstration of ice piracy, where flow into one glacier gradually switches to flow into another glacier, as the ocean melts the grounding zone and re-configures ice flow,” said Pierre Dutrieux, climate researcher at the <a href="https://www.bas.ac.uk/" target="_blank" rel="noreferrer noopener">British Antarctic Survey</a>.



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



The research team looked into several factors that influence ice flow, including <a href="https://www.earth.com/news/ocean-temperatures-are-rising-faster-than-expected-and-likely-to-accelerate/" target="_blank" rel="noreferrer noopener">ocean temperatures</a>, circulation changes, air temperature, and snowfall. 



They discovered that ice redirection is affecting the amount of ice reaching the floating ice shelves fed by these glaciers.



Two major ice shelves - the Crosson and <a href="https://www.earth.com/news/antarctica-ice-shapes-never-seen-by-humans-dotson-ice-shelf-ran-submersible/" target="_blank" rel="noreferrer noopener">Dotson</a> - are already among the fastest-changing outlets in West Antarctica. 



Crosson spans roughly 40 miles (60 kilometers), and Dotson stretches about 30 miles (48 kilometers). Both are thinning and retreating at their grounding lines.



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/05/Antarctica_ice-piracy_Crosson-Dotson-Ice-Shelves_map_ESA_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/05/Antarctica_ice-piracy_Crosson-Dotson-Ice-Shelves_map_ESA_1s.webp" alt="The Crosson and Dotson Ice Shelves are situated in West Antarctica.

“The changes in flow direction have substantially altered the ice mass flux into Dotson and Crosson Ice Shelves, likely playing an important role in maintaining Dotson and accelerating the deterioration of Crosson," explained Professor Anna Hogg, co-author and Professor of Earth Observation at the University of Leeds.



“This suggests that ice flow redirection is an important new process in contemporary <a href="https://www.earth.com/news/ice-sheet-fracture-sets-a-speed-record-in-antarctica/" target="_blank" rel="noreferrer noopener">ice sheet dynamics</a>, which is required to understand present-day structural change in glaciers and the future evolution of these systems.”



<h2 class="wp-block-heading" id="h-ice-piracy-rising-seas-global-impacts">Ice piracy, rising seas, global impacts</h2>



The stakes are high. Sea levels are already rising due to climate change, and over 410 million people could be affected by coastal flooding by the year 2100. <a href="https://www.earth.com/news/global-sea-levels-spiked-dramatically-in-2023/" target="_blank" rel="noreferrer noopener">Global sea levels</a> have increased by more than 10 centimeters over the past decade.



“This new study highlights the unique ability of satellites to provide both the temporal and spatial coverage required to assess change in the polar regions,” remarked Dr. Martin Wearing, ESA Digital Twin Earth Scientist and Polar Science Cluster Coordinator.



Using data from Copernicus Sentinel-1 and ESA's Earth Explorer CryoSat, the team has revealed the complex evolution of ice flow in part of West Antarctica over the past few decades. 



Understanding these changing dynamics and what drives them is crucial for improved projections of future ice-sheet change and contributions to sea-level rise.



<h2 class="wp-block-heading" id="h-what-does-it-all-mean">What does it all mean?</h2>



To sum it all up, the <a href="https://www.earth.com/news/antarctic-ice-sheet-past-present-and-future/" target="_blank" rel="noreferrer noopener">Antarctic ice sheet</a> - once thought to be sluggish and stable over millennia - is changing much faster than we realized, and in unexpected ways. 



This discovery of "ice piracy" shows that glaciers can dynamically interact, competing for ice and rerouting flow like rivers shifting course, which completely reshapes how we model future sea-level rise.



If one glacier can weaken another by stealing its ice, entire ice systems may destabilize quicker than predicted, feeding more ice into the ocean and raising sea levels. 



In plain terms: Antarctica isn’t just melting - it’s reorganizing itself in ways that could have big consequences for coastal cities around the world.

Ice piracy: Antarctic glacier discovered "stealing" ice from a neighbor, and that's not good for sea level rise

A new phenomenon dubbed "ice piracy" is unfolding in the frigid wilderness of West Antarctica, where one glacier appears to be stealing ice from its neighbor.

Experts at the <a href="http://www.rzym.pan.pl/en/about-us/polish-academy-of-sciences">Polish Academy of Sciences</a> have been investigating the decline of animals with white fur. The researchers warn that these creatures are especially vulnerable to <a href="https://www.earth.com/news/hurricanes-stronger-climate-change/">climate change</a>, as reduced snow cover makes it difficult for them to evade predators.

In the winter months, one subspecies of weasel replaces its brownish fur with a white coat so that it will be camouflaged by its surroundings. 

The research team captured and recorded 118 weasels in the Białowieża Forest between 1997 and 2007, some with white winter coats and others who kept their brown fur. 

According to the study, the number of days with permanent snow cover in the forest were cut in half - from 80 days to 40 days - between 1997 and 2007.

“In our study, the densities of weasels are about four to five times lower than 10 years ago,” said study co-author and biologist Dr. Karol Zub. This decline can be attributed to what experts call camouflage mismatch. In this case, white fur makes the weasels stand out.

Dr. Zub explained that camouflage mismatch may lead to the extinction of the white subspecies, which could be completely replaced by the brown subspecies. On the days without snow cover, as few as 20 percent of the total white-coated weasels were observed, indicating that many had been killed.

“By analyzing trapping data, we found the share of white subspecies in the weasel population inhabiting Bialowieza Forest decreases with decreasing numbers of days with snow cover,” said Dr. Zub.

“This led us to hypothesize selective predation pressure should favor one of the two phenotypes, according to the prevailing weather conditions in winter.”

“A simple field experiment with weasel models (white and brown), exposed against different background colors, revealed contrasting models faced significantly higher detection by predators.”

As snow cover continues to decline in some regions, other white-furred mammals and birds such as the Arctic fox will also be affected. However, there is some hope that animals will find ways to safely adapt to the changing climate conditions.

“We should not underestimate the power of natural selection,” said Dr. Zub. “We hope that along with future climate warming, autumn temperatures will also increase, providing an additional signal to the weasels to delay their moult.”

“Last autumn in our study was mild and under such conditions about half the weasels we observed started to moult at the beginning of January, whereas most weasels complete their moult by the end of November.”

The research was published in the journal <a href="http://www.nature.com/srep/">Scientific Reports</a>.

The opioid crisis has reached every corner of the United States, from sea to shining sea. Now, it seems, opioid addiction worries have trickled into the ocean itself off the coast of Washington. Scientists studying mussels transplanted into Puget Sound have discovered trace amounts of oxycodone in the shellfish.

"We found antibiotics, we found antidepressants, chemotherapy drugs, heart medications and then also oxycodone in the mussels from these mostly urbanized areas," biologist Dr. Jennifer Lanksbury told Seattle’s <a href="https://www.king5.com/article/tech/science/environment/opioids-found-in-puget-sound-mussels/281-558028458">K5 News</a>. Lanksbury led the study for the <a href="https://wdfw.wa.gov/">Washington Department of Fish and Wildlife</a>.

Every two years, the Puget Sound Mussel Monitoring Program takes mussels from uncontaminated water on Whidbey Island and transplant them for three winter months in Puget Sound.

Since mussels are filter feeders – animals that eat by straining food particles and other matter from the water around them – contaminants from polluted water tend to build up in their tissues over time.

After three months, each group of mussels is brought back to the lab and tested to see which pollutants might be found in the Seattle inlet.

The good news is that the problem is not widespread – yet. Oxycodone was only found in three groups of mussels, out of 18 total sets, and only in small amounts. And medical contaminants, which likely came from treated wastewater, were found only in the urban test sites, not in commercial shellfish beds.

“The concentrations of oxycodone in the mussels were about a hundred to five hundred times less than you would get in a normal therapeutic dose for humans,” Lanksbury told K5 News. “So you would have to eat a hundred-fifty pounds of mussels from that contaminated area to even get a minimal dose.”

The findings do raise concerns for other marine wildlife, however. Unlike humans, animals like chinook salmon are affected by a much lower dose of opioids like oxycodone.

“Because we’re finding them in mussels, that means that these chemicals are present in the water and that means that they’re likely affecting the fish and other invertebrates,” Lanksbury said.

Atmospheric rivers are long jet streams of air that carry large amounts of water vapor. They are often called “rivers in the sky” and can fuel storms that cause disastrous amounts of flooding due to the high levels of water vapor present in the air streams. 

In early 2017, <a href="https://www.earth.com/news/relentless-rain-california-nevada-west/">California</a> and much of the U.S. west coast was battered with severe flooding from atmospheric river storms. 

A new <a href="https://www.nasa.gov/">NASA</a> study examined the impact that climate change will have on atmospheric rivers around the world in an effort to provide a better understanding of the weather events. 

According to <a href="https://www.jpl.nasa.gov/news/news.php?feature=7141&amp;utm_source=iContact&amp;utm_medium=email&amp;utm_campaign=NASAJPL&amp;utm_content=daily20180524-2">NASA’s Jet Propulsion Laboratory</a> in California, atmospheric river research was previously limited to either the western United States or Europe. Different methods and results meant that climatologists were not able to compare studies or predict atmospheric river intensity across the globe.  

But this new study provides a method for predicting and evaluating the impacts of climate change on atmospheric river storms on a global scale, as opposed to isolated to a single region. 


The results, recently published in the journal Geophysical Research Letters, project that although atmospheric rivers may slightly decline in numbers, the frequency and intensity of atmospheric river storms will almost double. 

For the study, NASA researchers used global climate projections for the 21st century that were developed for the <a href="http://www.ipcc.ch/">Intergovernmental Panel on Climate Change</a> as well as an algorithm designed to detect atmospheric rivers around the world. 

The algorithm calculates the length, width, and amount of water vapor present in any given atmospheric river from model simulations. 

After applying the algorithm to both real-world observations and model simulations of climate for the 20th century, the researchers were able to show that model simulations accurately represented real-world data and events. 

Next, the researchers used the algorithm to predict atmospheric river events for the late 21st century in order to compare the effects of climate change on these weather events. 

The results showed that increases in global temperature and climate change would impact atmospheric rivers and intensity the frequency of storms even though the number of actual rivers would decrease. 

“The results project that in a scenario where greenhouse gas emissions continue at the current rate, there will be about 10 percent fewer atmospheric rivers globally by the end of the 21st century,” said Duane Waliser, the study’s lead author. “However, because the findings project that the atmospheric rivers will be, on average, about 25 percent wider and longer, the global frequency of atmospheric river conditions -- like heavy rain and strong winds -- will actually increase by about 50 percent.”

Now, because of this study, researchers and climatologists have a uniform way to study climate change and its effect on atmospheric rivers which will be critical for the regions already affected by heavy flooding from atmospheric river fueled storms.

A team of scientists led by the <a href="https://ncar.ucar.edu/">National Center for Atmospheric Research</a> (NCAR) is reporting on how past hurricanes would behave under the climate change conditions predicted by the end of this century. Each of the 22 storms analyzed for the study showed unique changes, but the hurricanes became longer, more intense, and much wetter on average.

Hurricane Ike, which devastated regions of the Gulf Coast and claimed over 100 lives, would linger for 17 percent longer, have 13 percent stronger winds, and would be 34 percent wetter under the future climate conditions.


Other <a href="https://www.earth.com/news/hurricanes-getting-stronger-faster/">storms</a> were found to be slightly weaker or slightly faster, but none were found to be drier. Across all of the simulated storms, rainfall increased dramatically.

“Our research suggests that future hurricanes could drop significantly more rain,” said lead author and NCAR scientist Ethan Gutmann. “Hurricane Harvey demonstrated last year just how dangerous that can be.”

Hurricane Harvey dumped more than four feet of rain in some regions and caused devastating flooding across the Houston area.

The researchers ran the Weather Research and Forecasting (WRF) model at a high resolution across the United States over two 13-year periods. The first model simulated weather from between 2000 and 2013, and the second simulated the same weather patterns with temperatures boosted by five degrees Celsius.

“Some past studies have also run the WRF at a high resolution to study the impact of climate change on hurricanes, but those studies have tended to look at a single storm, like Sandy or Katrina,” explained Gutmann.

“What we find in looking at more than 20 storms is that some change one way, while others change in a different way. There is so much variability that you can't study one storm and then extrapolate to all storms.”


Overall, the simulated storms had six percent stronger average maximum wind speeds and moved about nine percent more slowly. In addition, average rainfall rates were 24 percent higher.

“This study shows that the number of strong hurricanes, as a percent of total hurricanes each year, may increase,” said co-author Ed Bensman. “With increasing development along coastlines, that has important implications for future storm damage.”

The research is published in the <a href="https://journals.ametsoc.org/loi/clim">Journal of Climate</a>.

The <a href="https://www.earth.com/news/country-paris-agreement/">Paris Agreement</a> of the United Nations is a global effort to prevent an increase in the Earth’s climate of 2°C. Almost every country on the planet has agreed to do what it takes to prevent this level of warming becoming a reality – minus the United States, the only country to withdraw. But now, a collaborative research team from China has published a new analysis that predicts the Earth’s climate could increase by 4°C by 2084, compared to pre-industrial levels.

Researcher Dabang Jiang of <a href="http://english.iap.cas.cn/">the Institute of Atmospheric Physics of the Chinese Academy of Sciences</a> and his team used the parameters of a scenario in which there was no mitigation of rising greenhouse gas emissions. They compared 39 coordinated climate model experiments from the fifth phase of the Coupled Model Intercomparison Project, which creates and reviews climate models in order to ensure the climate simulations are as accurate as possible. 

The results showed that most models project an increase of 4°C as early as 2064 and as late as 2095 in the 21st century. 

“A great many record-breaking heat events, heavy floods, and extreme droughts would occur if global warming crosses the 4 °C level, with respect to the preindustrial period,” says Jiang. “The temperature increase would cause severe threats to ecosystems, human systems, and associated societies and economies.”

This temperature increase is a result of more annual and seasonal warming over land than over the ocean, and significant warming in the Arctic. Precipitation would likely increase in the Arctic and the Pacific, and the variability of temperature throughout a year would be lower in the tropics and higher in the polar regions. 

“Such comparisons between the three levels of global warming imply that global and regional climate will undergo greater changes if higher levels of global warming are crossed in the 21st century,” says Jiang.

The research team is continuing to study the changes that are associated with a 4°C increase in extreme climates. “Our ultimate goal is to provide a comprehensive picture of the mean and extreme climate changes associated with higher levels of global warming based on state-of-the art climate models, which is of high interest to the decision-makers and the public,” says Jiang.

The growing issue of antibiotic resistance has now been linked to <a href="https://www.earth.com/news/climate-change-fish-north-fishing-business/">climate change</a>. A team of epidemiologists led by <a href="https://hms.harvard.edu/">Harvard Medical School</a> discovered that higher local temperatures are associated with increased antibiotic resistance in common bacterial strains. 

Study lead author Derek MacFadden is an infectious disease specialist at <a href="http://www.childrenshospital.org/">Boston Children's Hospital</a>.

“The effects of climate are increasingly being recognized in a variety of infectious diseases, but so far as we know this is the first time it has been implicated in the distribution of antibiotic resistance over geographies,” said MacFadden.

“We also found a signal that the associations between antibiotic resistance and temperature could be increasing over time.”

According to the <a href="https://www.cdc.gov/">Centers for Disease Control and Prevention</a>, antibiotics are unnecessarily prescribed around 30 percent of the time, which was previously believed to be the cause of rising antibiotic resistance.

In the current study, the team used hospital and lab data from between 2013 and 2015 to examine antibiotic resistance in E. coli, K. pneumoniae and S. aureus. The investigation included more than 1.6 million bacterial specimens from 223 facilities across 41 states.

The study revealed that an increase in temperature of 18 degrees Fahrenheit boosted antibiotic-resistant strains of K. pneumoniae by 2.2 percent, S. aureus by 3.6 percent, and E. coli by 4.2 percent.

“Estimates outside of our study have already told us that there will already be a drastic and deadly rise in antibiotic resistance in coming years,” said co-senior author John Brownstein.


“But with our findings that climate change could be compounding and accelerating an increase in antibiotic resistance, the future prospects could be significantly worse than previously thought.”

The team also found a link between antibiotic resistance and population density.

“Population growth and increases in temperature and antibiotic resistance are three phenomena that we know are currently happening on our planet,” explained senior author Mauricio Santillana. “But until now, hypotheses about how these phenomena relate to each other have been sparse.”


Brownstein said that the research highlights an urgent need to gain a better understanding of how our changing environment is interconnected with infectious disease and medicine.


The study is published in the journal <a href="https://www.nature.com/nclimate">Nature Climate Change</a>.

When a <a href="https://www.earth.com/news/changes-jet-stream-weather/">jet stream</a> causes large masses of air to stall out and linger, this process is known as atmospheric blocking. Researchers have found that blocked atmospheric circulations closely resemble traffic jams.

Atmospheric blocking can cause weather patterns to stall over the same regions, triggering floods, heat waves, droughts, and other severe weather events. 

The exact cause of blocking is not very well understood, and neither is the influence that climate change may have on the frequency of blocking events. This uncertainty makes it difficult to accurately predict weather.

Noboru Nakamura is a researcher in Atmospheric and Environmental Fluid Dynamics. He teamed up with Clare Huang to develop a new system for interpreting the nature of atmospheric blocking. 

To understand the processes underlying blocking, the experts combined the use of mathematical theory with a metric for assessing jet streams which they had previously developed.

The study revealed that jet streams which become blocked appear to be very similar to traffic jams, in terms of flow and density of vehicles. 

In light traffic, most cars travel at around the same speed which makes the traffic flow proportionate to traffic density. When traffic becomes congested, the flow of traffic is slowed down, which is precisely what happens to air flow in atmospheric blocking.

Blocking slows down eastward winds, and a highly meandering jet stream can also steer extreme weather. In 2012, atmospheric blocking is what drove Superstorm Sandy onto an unexpected path toward New Jersey. 

The authors found that climate change has the potential to alter the frequency of atmospheric blocking by changing the risk for a jet stream to hit capacity and become overcrowded.

The study is published by the <a href="http://www.aaas.org/">American Association for the Advancement of Science</a> (AAAS) in the journal <a href="http://www.sciencemag.org/">Science</a>.

A team of researchers may have finally settled a long-standing debate on what temperatures were like after the <a href="https://www.earth.com/news/dinosaurs-asteroid-struck/">Chicxulub asteroid</a> event 65 million years ago. The experts found that the asteroid strike triggered global warming and drove temperatures up by five degrees Celsius, which persisted for around 100,000 years.

After the asteroid crashed into the Earth, systems were disturbed at a rate much faster than the shift that is currently being caused by human activities. Understanding the extreme impact of the event can give scientists insight into the environmental changes that are happening now. 

There has been much debate over what happened in the aftermath of the Chicxulub asteroid strike. Some scientists support the theory that global cooling set in after soot in the atmosphere blocked out the sun, while others believe that carbon dioxide released upon impact led to global warming.

A team of researchers led by Ken MacLeod set out to determine how temperatures were affected after the asteroid strike by analyzing the well-preserved remains of fish teeth, scales, and bone from a site in Tunisia. The samples have oxygen isotopic signatures that can reveal the temperature at the time the animals were still living.

The experts examined fossils from sediments that range from the time leading up to the Chicxulub impact until long after the event took place. 

The investigation showed that global temperatures increased by about five degrees Celsius and persisted for roughly 100,000 years after the asteroid struck the Earth. The extent and duration of global warming identified in the study closely correlate with levels of carbon dioxide that were reported in other analyses of the Chicxulub event.

The study is published by the <a href="http://www.aaas.org/">American Association for the Advancement of Science</a> (AAAS) in the journal <a href="http://www.sciencemag.org/">Science</a>.

Chicxulub asteroid strike drove temperatures up for 100,000 years

A team of researchers may have finally settled a long-standing...

While the majority of the world’s governments are in agreement that human activities are at the core of climate change and that action must be taken to reduce emissions, the Trump administration has continued to ignore science. 

Trump himself has famously called climate change “a hoax” and even taunted political opponents during the cold days of winter, claiming the northeast “could use some global warming.” Oddly, Trump’s own administration still released an <a href="https://www.earth.com/news/humans-driving-climate-change/">official government report</a> stating in no uncertain terms that human activity is driving climate change.

Now, according to a recent report from the <a href="https://www.washingtonpost.com/news/energy-environment/wp/2018/05/23/in-an-internal-memo-the-white-house-considered-whether-to-simply-ignore-federal-climate-research/?utm_term=.b4956e50d50d">Washington Post</a>, an internal memo from last year showed the White House weighing its options of whether to simply “ignore” all climate change research, or to actually develop a “fact-based” approach.

It was an internal document written by Michael Catanzaro, the president’s special assistant for domestic energy and environmental policy at the time the memo was drafted. 

The memo, according to the Washington Post, was presented to a staff of senior White House and agency officials in September and discussed having an official stance on climate change. 

Catanzaro wrote wondering whether the Trump administration should “consider having a firm position on and a coherent, fact-based message about climate science — specifically, whether, and to what extent, anthropogenic emissions of greenhouse gases are affecting the climate system, and what level of concern that warrants.”

The options presented by Catanzaro included the possibility of a red and blue debate to show the inconsistencies and uncertainties of climate science, or the option to just ignore all climate science. None of the options involved emphasizing or “touting” climate study findings. 

The administration didn't take any formal position on climate change, but as Trump continues to push for coal and other fossil fuels as well confuse weather events as a means to disprove climate change, the unofficial position is clear. 

Yet, despite the new administration's attempts to largely ignore federal scientific findings, new reports and studies continue to be published that show the clear harmful effects of human activities on the world’s climate.

“The scientific evidence about accelerating effects of carbon dioxide and greenhouse gases in the atmosphere is so strong, and so prevalent, that it would be impossible to hush it up even if you wanted to,” Rush Holt, CEO of the <a href="http://www.aaas.org/">American Association for the Advancement of Science</a> told the Washington Post. “Coral deaths and glacier melting and sea-level rise, and all of these things are just so well documented and there’s just new evidence every day, whether it’s from <a href="https://www.usgs.gov/">USGS</a>, or [<a href="http://www.noaa.gov/">the National Oceanic and Atmospheric Administration</a>], or<a href="https://www.nasa.gov/"> NASA</a>, or <a href="https://www.energy.gov/">Department of Energy</a>, or various academic institutions. It just can’t be swept under the rug.”

How long can the Trump admin ignore climate change science?

While the majority of the world’s governments are in agreement...

An international research team led by the <a href="https://www.u-tokyo.ac.jp/en/index.html">University of Tokyo</a> has found that rising levels of <a href="https://www.earth.com/news/carbon-dioxide-record-broken/">carbon dioxide</a> (CO2) will lower the nutritional value of rice. 

When rice was grown under the atmospheric conditions that are expected in the second half of this century, iron, zinc, protein, and vitamins B1, B2, B5, and B9 were all reduced.

Study co-author Professor Kazuhiko Kobayashi is an expert on the impacts of air pollution on agriculture.

“Rice is not just a major source of calories, but also proteins and vitamins for many people in developing countries and for poorer communities within developed countries,” said Professor Kobayashi.

People in countries with the highest rice consumption and the lowest gross domestic product could face increasing rates of malnutrition as the nutritional value of rice  and other low-cost foods decline. 

However, not all types of rice responded to the experiential conditions in the same way, which means there is a chance that scientists could identify varieties of rice that maintain their nutritional value regardless of CO2 levels.

The rice was grown at research sites in China and Japan, where researchers built 55-foot-wide plastic pipes elevated about a foot above the tops of plants within standard rice fields. Wind speed and direction were measured by a network of sensors and monitors to control how much carbon dioxide was released out of the pipes, which is a technique known as Free-Air Carbon dioxide Enrichment (FACE).

“I first started using this technique in 1998, because we knew that plants raised in a plastic or glass house do not grow the same as plants in normal, open field conditions,” explained Professor Kobayashi. 

“This technique allows us to test the effects of higher carbon dioxide concentrations on plants growing in the same conditions that farmers really will grow them some decades later in this century.”

There were some challenges to overcome, such as the interference of wild animals.


“At our first field site, we learned we have to keep all of the pipes and tubes above the ground because raccoons kept chewing through everything and jeopardized the experiment,” said Professor Kobayashi.


Researchers analyzed a total of 18 different varieties of rice to look for protein, iron, and zinc levels, while nine varieties of rice grown in China were used for testing levels of vitamins B1, B2, B5, and B9.

Six hundred million people in regions such as Bangladesh, Cambodia, Indonesia, Lao People's Democratic Republic, Myanmar, Vietnam, and Madagascar get at least 50 percent of their daily protein directly from rice. 

The research is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

Rice will lose nutritional value as carbon dioxide levels rise

An international research team led by the University of Tokyo...

A team of scientists has revealed that dinosaurs were not the only casualty of the catastrophic asteroid event 66 million years ago. The experts have discovered that the world's forests were also completely destroyed, which caused the extinction of tree-dwelling birds.

Study co-author Regan Dunn is a paleontologist at the <a href="https://www.fieldmuseum.org/">Field Museum</a> in Chicago.

“Looking at the fossil record, at plants and birds, there are multiple lines of evidence suggesting that the forest canopies collapsed,” said Dunn.

Lead author Daniel Field explained that the team used a combination of techniques for the investigation. 

“We concluded that the temporary elimination of forests in the aftermath of the asteroid impact explains why arboreal birds failed to survive across this extinction event,” said Field. “The ancestors of modern arboreal birds did not move into the trees until forests had recovered from the extinction-causing asteroid.”

Study co-author Antoine Bercovici is a pollen expert at the <a href="https://www.si.edu/">Smithsonian Institution</a> and the Denver Museum of Nature and Science, Bercovici analyzed microscopic fossils of pollen and spores to determine that the planet's forests were destroyed. 

“After a disaster like a forest fire or a volcanic eruption, the first plants to come back are the fastest colonizers - especially ferns,” said Dunn. This is due to fact that ferns do not sprout from seeds, but from small spores that are made up of just a single cell. 

"Spores are minuscule, the size of a grain of pollen, so they're easily dispersed. They get picked up by the wind and go further than seeds can, and all they need to grow is a wet spot.”

"The spores are tiny - you could fit four across a single strand of your hair. To see them, we take a sample of rock from the time frame just after the collision and dissolve it in acid. Then we purify it so that all that remains is the organic debris, like pollen, spores and little leaf bits, then we look at them under a microscope.”


Immediately after the <a href="https://www.earth.com/news/dinosaurs-asteroid-struck/">asteroid</a> collided with the Earth, the fossil record showed the charcoal remains of trees, and then, tons of fern spores. 

“Our study examined the fossil record from New Zealand, Japan, Europe and North America, which showed there was a mass deforestation across the globe at the end of the Cretaceous period,” said Bercovici.

The researchers found that the only birds that survived were ground-dwellers. Their fossilized remains contained strong legs like modern ground birds such as kiwis and emus. Tree-dwelling birds have delicate legs that are designed for perching on branches, and they had no place left to live.

“Today, birds are the most diverse and globally widespread group of terrestrial vertebrate animals--there are nearly 11,000 living species,” said Field. “Only a handful of ancestral bird lineages succeeded in surviving the mass extinction event 66 million years ago, and all of today's amazing living bird diversity can be traced to these ancient survivors.”

Dunn pointed out that fossil plants are critical in reconstructing the history of life on earth. 

“Plants are everything, plants are the context in which all terrestrial life evolves and survives. They're primary producers, they make energy available to all life forms by capturing it from the sun--we can't do that.”


Dunn also emphasized that the loss of life resulting from the mass extinction 66 million years ago is relevant today.


“The end-Cretaceous event is the fifth mass extinction - we're in the sixth,” said Dunn. "It's important for us to understand what happens when you destroy an ecosystem, like with deforestation and climate change--so we can know how our actions will affect what comes after us."

The study is published in the journal <a href="https://www.cell.com/current-biology/home">Current Biology</a>.

When researchers study population declines, they often cite the vital importance of <a href="https://www.earth.com/news/location-crucial-wildlife-conservation/">conservation</a>, management, and restoration efforts. 

But sometimes it can be difficult to grasp the full weight of just how many species are threatened, endangered, and even facing extinction when studies focus on one species or habitat at a time. 

According to the <a href="https://www.iucn.org/">International Union for the Conservation of Nature</a> (IUCN), nearly 80,000 plants and animals are endangered and are part of the IUCN’s Red List. 

Of those 80,000, almost a third could soon face extinction with 41 percent of amphibians, 34 percent of conifer trees, and 25 percent of mammals in jeopardy, according to a recent <a href="https://www.yahoo.com/news/conservationists-fight-save-animals-mass-extinction-looms-093541915.html">Agence France-Presse (AFP) article. </a>

These numbers are grim, but there are quite a few success stories that could serve as inspiration to help reverse further population declines. 

Conservationists have brought quite a few species back from the brink, thanks to captive breeding, tracking populations, and restoring habitats. 

The Mauritius kestrel, a falcon whose species was all but wiped in 1974, is now an example of one of the most successful bird restoration projects in history. Captive breeding and predator control has increased Mauritius kestrel numbers from four to four hundred. 

Another example of successful conservation can be found on Madagascar with the greater bamboo lemur. The species is still seriously threatened, but a national park was erected around the lemurs' natural habitat, protecting it from future declines. 

Conservationists can work to raise awareness of endangered or threatened species among a community, or work with policymakers and national leaders to reduce human activities near reduced habitats. 

“The sixth mass extinction is happening now,” said Craig Hilton-Taylor, the head of the Red List, told the AFP. “But these conservation achievements highlight that there is still reason to be hopeful for the future of our planet, and that conservation does work.”

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

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.
