The Effect of Arctic Sea-Ice Loss on Extratropical Cyclones

Published:September 2023

Author(s):Stephanie Hay, Matthew D. K. Priestley, Hao Yu, Jennifer L. Catto, James A. Screen

Publisher: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 →

Unlock the Endangered Species Act to address GHG emissions

Published:August 2023

Author(s):Steven C. Amstrup, Cecilia M. Bitz

Publisher: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 →

Sensitivity of arctic CH₄ emissions to landscape wetness diminished by atmospheric feedbacks

Published:July 2023

Author(s):Philipp de Vrese, Lutz Beckebanze, Leonardo de Aro Galera, Thomas Kleinen, Lars Kutzbach, Zoé Rehder, and Victor Brovkin

Publisher:Nature Climate Change

This peer-reviewed study uses climate modeling to show that atmospheric feedbacks may accelerate increases in methane emissions from arctic permafrost due to thaw-induced drying of permafrost landscapes.Read More →

Widespread natural methane and oil leakage from sub-marine Arctic reservoirs

Published:March 2023

Author(s):Pavel Serov, Rune Mattingsdal, Monica Winsborrow, Henry Patton, Karin Andreassen

Publisher:Nature Communications

This peer-reviewed study presents empirical observations of hitherto undocumented, widespread and extensive methane and oil release from geological reservoirs to the Arctic Ocean.Read More →

Thermokarst acceleration in Arctic tundra driven by climate change and fire disturbance

Published:December 2021

Author(s):Yaping Chen, Mark J. Lara, Benjamin M. Jones, Gerald V. Frost, Feng Sheng Hu

Publisher:One Earth

This study identifies climate change as the principal driver of all thermokarst formed during 1950–2015 and predicts that climate change and wildfire will synergistically accelerate thermokarst as the Arctic transitions in this century.Read More →

Arctic Report Card 2021: Rapid and pronounced warming continues to drive the evolution of the Arctic environment

Published:December 2021

Author(s):Twila A. Moon, Matthew L. Druckenmiller, Richard L. Thoman

Publisher:NOAA

This report provides environmental information on the current state of different components of the Arctic environmental system relative to historical records.Read More →

New climate models reveal faster and larger increases in Arctic precipitation than previously projected

Published:November 2021

Author(s):Michelle R. McCrystall, Julienne Stroeve, Mark Serreze, Bruce C. Forbes, & James A. Screen

Publisher:Nature Communications

This study demonstrates that the transition from a snow- to rain-dominated Arctic in the summer and autumn is projected to occur decades earlier and at a lower level of global warming than previously thought.Read More →
