If the world keeps increasing greenhouse gas emissions at its current speed, all sea ice in the Arctic will disappear in the 2030s, an event that could at best be postponed until the 2050s should emissions be somehow reduced.
The growing frequency and intensity of heat waves around the globe pose “a substantial, persistent ‘non-combat threat’” to military training and operations, according to experts in environmental, thermoregulatory and cardiovascular physiology.
A recent study led by a researcher at the Friedman School of Nutrition Science and Policy at Tufts University found that the likelihood of extreme temperatures that could affect crop yields has increased significantly in wheat-producing regions of the U.S. and China.
A new study from Lund University in Sweden shows that the ability of microorganisms to adapt to climate warming will slow down global warming by storing carbon in soil.
A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.
A new study provides insight into consumers’ interest in home cooling by analyzing social media data.
A new survey from the American Academy of Sleep Medicine (AASM) reveals that one-third of adults (32%) “always or often” lose sleep at night due to worries about environmental issues, and younger generations are more likely to lose sleep due to these worries.
ALBANY, N.Y. (April 19, 2023) – Saturday marks the tradition known as “Earth Day,” an annual event that promotes awareness about climate change and other environmental issues that threaten the health of our planet. First held on April 22, 1970,…
As climate change causes ocean temperatures to rise, one of Greenland’s previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.
Aerosols particles in the atmosphere are an important factor in the Earth’s climate, but researchers lack information on these aerosols’ molecular composition, especially for aerosols during the day and night above agricultural fields. In this research, scientists examined secondary organic aerosols over agricultural fields in the Southern Great Plains in Oklahoma. They found that the aerosols’ composition and structure differ from day to night and that some aerosols are ultimately from urban sources.
Researchers estimated that climate change-related natural disasters have increased since 1980 and have already cost the United States more than $2 trillion in recovery costs. Their analysis also suggests that as atmospheric carbon dioxide levels and the global temperature continue to rise, the frequency and severity of disasters will increase, with recovery costs potentially rising exponentially.

Current severe heatwaves that will likely increase in severity and frequency in the future are driving a rise in the use of air conditioners, threatening the environment with their high energy consumption and refrigerants with high warming potential. A new study finds that switching to propane as a refrigerant could lessen the global temperature increase from space cooling.
A new analysis of observed temperatures shows the Arctic is heating up more than four times faster than the rate of global warming. The trend has stepped upward steeply twice in the last 50 years, a finding missed by all but four of 39 climate models.
Climate change might be behind an unusual disease outbreak among Antarctic fish. For about a decade, University of Oregon biologists John Postlethwait and Thomas Desvignes have been visiting the West Antarctic Peninsula. They study a unique group of fish that has adapted to the harsh polar environment. But on a 2018 field excursion, they noticed something especially strange: a large number of those fish were afflicted with grotesque skin tumors.
Instead of focusing on carbon dioxide’s effect on future temperature, new research includes the related human-generated emissions of methane, nitrogen oxide and particle pollution. Expanding the scope increases the amount of future warming that is already guaranteed by past emissions, and shortens the timeline to reach the Paris Agreement temperature targets.
As the impacts of climate change are felt around the world, no area is experiencing more drastic changes than the northern polar region.
