Earth’s oceans are home to some of the most diverse ecosystems on the planet, but warming temperatures are causing many marine animals, including coral, to die out.
As the impacts of climate change are felt around the world, no area is experiencing more drastic changes than the northern polar region.
Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak midsummer sun causes rapid changes. In this aspect, it seems, it's Arctic sea ice that is more mysterious.
A new study led by Georgia Tech points to possible help for restoring marine ecosystems — and provides more data on the role microbes play in marsh plant health and productivity.
A first-of-its-kind study shows that some ocean animals may be able evolve their way out of troubles caused by climate change—but at a high cost. By artificially evolving 23 generations of a marine copepod, Acartia tonsa, a team of scientists at the University of Vermont found that the tiny creatures could adapt to the high temperatures and carbon dioxide levels forecast for the warming oceans. But to get there, the populations had to spend a lot of their genetic flexibility—leaving them vulnerable to new stresses, like low food.
New analysis confirms a palpable change in fire dynamics already suspected by many.
The boreal forest is a belt of cold-tolerant conifer trees that stretches nearly 9,000 miles across northern North American and Eurasia; it makes up almost a quarter of the Earth's forest area. It's also the coldest—and most rapidly warming—forest biome on the planet, and its shifting characteristics amid climate change are raising concerns about increased fire activity, decreased biodiversity and other long-term adverse effects for the human and natural ecosystems.
Scientists have long hypothesized that climate change, by intensifying stressors like drought or wildfires, would make an ecosystem more vulnerable to invasive plants. Those invasive plants may in turn alter the environment in ways that amplify the impacts of climate change, explained Luke Flory, a professor of ecology in the UF/IFAS agronomy department. A new long-term field study conducted by Flory’s lab offers the first experimental evidence to support this hypothesis.
While climate change is making much of the world warmer, temperatures in a subpolar region of the North Atlantic are getting cooler. A team of researchers report that changes in the wind pattern, among other factors, may be contributing to this “cold blob.”
Shrubs in the desert Southwest have increased their water use efficiency at some of the highest rates ever observed to cope with a decades-long megadrought. That’s the finding of a new study from University of Utah researchers, who found that although the shrubs’ efficiency increases are unprecedented and heroic, they may not be enough to adapt to the long-term drying trend in the West.
Increasing adoption of certain agricultural practices can help combat climate change, according to a new report by researchers from Rutgers and the University of Maine. The study explores how New Jersey’s plants and soils can help to absorb and store carbon dioxide from greenhouse gas emissions.

Climate models predict that rainfall variability over wet regions globally will be greatly enhanced by global warming, causing wide swings between dry and wet conditions, according to a joint study by the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS) and the Met Office, the UK's national meteorological service.
A model of the eastern California forests of the Sierra Nevada looks at the longer-term future of wildfires under future climate change scenarios. Results show an initial roughly decade-long burst of wildfire activity, followed by recurring fires of decreasing area — a pattern that could apply to other drought-prone regions of the West.
Irvine, Calif., July 22, 2021 – To meet an ambitious goal of carbon neutrality by 2045, California’s policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem’s ability to perform this service.
Wildfire smoke may greatly increase susceptibility to SARS-CoV-2, the virus that causes COVID-19, according to new research from the Center for Genomic Medicine at the Desert Research Institute (DRI), Washoe County Health District (WCHD), and Renown Health (Renown) in Reno, Nev.
Irvine, Calif., June 21, 2021 – A shift is happening in Southern California, and this time it has nothing to do with earthquakes. According to a new study by scientists at the University of California, Irvine, climate change is altering the number of plants populating the region’s deserts and mountains. Using data from the Landsat satellite mission and focusing on an area of nearly 5,000 square miles surrounding Anza-Borrego Desert State Park, the research team found that between 1984 and 2017, vegetation cover in desert ecosystems decreased overall by about 35 percent, with mountains seeing a 13 percent vegetation decline.
Last fall, the Mullen fire west of Laramie raged for the better part of two months, burning more than 176,000 acres and 70 structures in Wyoming's Carbon and Albany counties, and in Jackson County, Colo.

Where does snow come from? This may seem like a simple question to ponder as half the planet emerges from a season of watching whimsical flakes fall from the sky--and shoveling them from driveways. But a new study on how water becomes ice in slightly supercooled Arctic clouds may make you rethink the simplicity of the fluffy stuff. It describes definitive, real-world evidence for "freezing fragmentation" of drizzle as a major source of ice in slightly supercooled clouds. The findings have important implications for forecasting weather and climate.
An unprecedented bulge of fresh water in the Arctic Ocean will travel through the Canadian Archipelago to the Labrador Sea, affecting local marine environments and global ocean circulation.

How did rocks rust on Earth and turn red? A Rutgers-led study has shed new light on the important phenomenon and will help address questions about the Late Triassic climate more than 200 million years ago, when greenhouse gas levels were high enough to be a model for what our planet may be like in the future.
Antarctic ice is melting, contributing massive amounts of water to the world’s seas and causing them to rise – but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years’ worth of satellite data indicates.
Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2).
A first-of-its-kind, international study of 107,000 children finds that higher temperatures are an equal or even greater contributor to child malnutrition than the traditional culprits of poverty, inadequate sanitation, and poor education. The 19-nation study is the largest investigation to date of the relationship between our changing climate and children's diet diversity. Of the six regions examined--in Asia, Africa, and Central and South America--five had significant reductions in diet diversity associated with higher temperatures.
The planet is committed to global warming in excess of 2 degrees Celsius (3.6°F) just from greenhouse gases that have already been added to the atmosphere. This is the conclusion of new research by scientists from Nanjing University, Lawrence Livermore National Laboratory (LLNL) and Texas A&M University, which appears in the latest edition of Nature Climate Change.
