A study reveals interconnected changes under three emissions pathways and describes the emerging challenges facing Antarctic fieldwork.
Climate Change
Tropopause Temperature Drives Tropical Cyclone Simulation Diversity
Tropopause temperature biases create major tropical cyclone differences in models; cooler air boosts storm potential intensity, raising global cyclone frequency and hurricanes in experiments.
A Long-Term Look Beneath an Antarctic Ice Shelf
More than 4 years of data from a borehole in the Ross Ice Shelf reveal supercooled water and more.
COVID-19 Shutdowns Saw Human Emissions Slow, but Atmospheric Methane Surged
An uptick in wetland emissions, as well as a scarcity of atmospheric OH radicals, contributed to the counterintuitive methane spike.
The “Wet-Gets-Wetter” Response to Climate Change Does Not Always Apply
While the precipitation response to a warming climate is often stated as the “wet gets wetter,” this response does not apply to east-west overturning circulations like the Pacific Walker circulation.
Antarctic Ice Sheet Has Lost a Connecticut-Sized Amount of Ice Over the Past 30 Years
A new study of Antarctica has found that since 1996, its ice sheet has lost 12,820 square kilometers (nearly 5,000 square miles) of ice—nearly enough to cover the state of Connecticut, or 10 cities the size of Greater Los Angeles.
Greenland Dust Delivers Nutrients to Ice-Melting Algae
Researchers scrutinized aerosols above and within the ice sheet, finding phosphorus and other mineral particles.
Marine Heat Waves Can Increase Coastal Rainfall
Unusually warm ocean waters can amplify extreme rainfall in downwind areas, leaving coastal communities—especially those in developing countries—at risk.
Understanding Aerosol-Cloud Interactions is Pivotal for Improving Climate Predictions
Global cooperation and knowledge sharing are essential to improve our understanding of cloud formation and evolution through aerosol-cloud interaction.
With the Ocean Included, the Social Cost of Carbon Doubles
A new calculation includes ocean ecosystems when assessing the monetary impact of climate change.
