Increasing large wildfires over the western United States linked to diminishing sea ice in the Arctic

Published:October 2021

Author(s):Yufei Zou, Philip J. Rasch, Hailong Wang, Zuowei Xie, & Rudong Zhang

Publisher:Nature Communications

This study shows that increasing large wildfires during autumn over the western U.S. are fueled by more fire-favorable weather associated with declines in Arctic sea ice. Arctic sea iceRead More →

Future increases in Arctic lightning and fire risk for permafrost carbon

Published:April 2021

Author(s):Yang Chen, David M. Romps, Jacob T. Seeley, Sander Veraverbeke, William J. Riley, Zelalem A. Mekonnen, James T. Randerson

Publisher:Nature

Lightning increases may induce a fire–vegetation feedback whereby more burning in Arctic tundra expedites the northward migration of boreal trees, with the potential to accelerate the positive feedback associated with permafrost soil carbon release.Read More →

CMIP5 Model-based Assessment of Anthropogenic Influence on Highly Anomalous Arctic Warmth During November–December 2016

Published:March 2018

Author(s):Jonghun Kam, Thomas R. Knutson, Fanrong Zeng, Andrew T. Wittenberg

Publisher:Bulletin of the American Meteorological Society (BAMS)
