The Effect of Arctic Sea-Ice Loss on Extratropical Cyclones

September 2023
Stephanie Hay, Matthew D. K. Priestley, Hao Yu, Jennifer L. Catto, James A. Screen
Geophysical Research Letters
This peer-reviewed study examines how cyclones may change as Arctic sea ice diminishes. In northern mid-latitudes winter storms will be weaker, slower moving, but longer lasting, and Pacific storm tracks will shift towards North America.Read More →

Warming temperatures exacerbate groundwater depletion rates in India

September 2023
Nishan Bhattarai, David B. Lobell, Balwinder-Singh, Ram Fishman, William P. Kustas, Yadu Pokhrel, Meha Jain
Science Advances
This peer-reviewed study finds that farmers in India have adapted to warming temperatures by drawing down groundwater reservoirs, and that regional groundwater loss from 2041-2080 could be three times current depletion rates.Read More →

The Largest Ever Recorded Heatwave—Characteristics and Attribution of the Antarctic Heatwave of March 2022

August 2023
Edward Blanchard-Wrigglesworth, Tyler Cox, Zachary I. Espinosa, Aaron Donohoe
Geophysical Research Letters
This peer-reviewed study focuses on the record-breaking Antarctic heatwave in March 2022, assesses the implications of this heatwave for widely-used climate models, and models the impact of anthropogenic climate change on this and future heatwaves. Read More →

Unlock the Endangered Species Act to address GHG emissions

August 2023
Steven C. Amstrup, Cecilia M. Bitz
Science
This peer-reviewed policy forum piece quantifies the relationship between anthropogenic GHG emissions and polar bear population levels, and discusses the impact of this finding on their endangered species status in the United States.Read More →

Decreasing fire season precipitation increased recent western U.S. forest wildfire activity

August 2023
Zachary Holden, Alan Swanson, Charles Luce, W. Jolly, Marco Maneta, Jared Oyler, Dyer Warren, Russell Parsons, and David Affleck
Proceedings of the National Academy of Sciences
This peer-reviewed study uses climate modeling and statistical analysis of precipitation trends from 1979 to 2015 in the western United States to show that declines in summer precipitation contributed to the area of land burned by wildfires.Read More →
