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 →

Wildfire and degradation accelerate northern peatland carbon release

April 2023
S. Wilkinson, R. Andersen, P. Moore, S. Davidson, and J. Waddington
Nature Climate Change
This peer-reviewed study uses datasets from natural, degraded, and restored northern peatlands to show that increased wildfire incidence caused by human activity reduces the carbon sink provided by peatlands.Read More →

Synthesis Report of the IPCC Sixth Assessment Report

March 2023
Intergovernmental Panel on Climate Change
Intergovernmental Panel on Climate Change
This Synthesis Report summarizes the state of knowledge of climate change, its widespread impacts and risks, and climate change mitigation and adaptation, based on the peer-reviewed scientific, technical and socio-economic literature since 2014.Read More →

Record-high CO2 emissions from boreal fires in 2021

March 2023
Bo Zheng, Philippe Ciais, Frederic Chevallier, Hui Yang, Josep G. Canadell, Yang Chen, Ivar R. Van Der Velde, Ilse Aben, Emilio Chuvieco, Steven J. Davis, Merritt Deeter, Chaopeng Hong, Yawen Kong, Haiyan Li, Hui Li, Xin Lin, Kebin He, Qiang Zhang
Science
This peer-reviewed study finds that an increase in extreme boreal fires in 2021 resulted in increased CO2 emissions. Increasing numbers of extreme boreal fires and stronger climate–fire feedbacks challenge climate mitigation efforts.Read More →

Forest fire threatens global carbon sinks and population centres under rising atmospheric water demand

November 2022
Hamish Clarke, Rachael H. Nolan, Victor Resco De Dios, Ross Bradstock, Anne Griebel, Shiva Khanal & Matthias M. Boer
Nature Communications
This study finds that climate change is projected to lead to widespread increases in fire risk, with at least 30 additional days above critical thresholds for fire activity in forest biomes on every continent by 2100 under rising emissions scenarios.Read More →

Increasing western wildfire impacts on snowpack in the western U.S.

September 2022
Stephanie Kampf, Daniel McGrath, Megan Sears, Steven Fassnacht, Leonie Kiewiet, and John Hammond
Proceedings of the National Academy of Sciences
This peer-reviewed study uses satellite mapping of snow pack in the western United States and government wildfire area datasets to show that wildfires are decreasing snow pack and shifting towards areas with late snow melt.Read More →

Frontiers 2022: Noise, Blazes and Mismatches

February 2022
United Nations Environment Programme
United Nations Environment Programme
This report highlights the role of climate change and human influence in the changing wildfire regimes around the world, and the role of climate change in disrupting the life cycle patterns of plant and animal species.Read More →

Warming weakens the night-time barrier to global fire

February 2022
Jennifer K. Balch, John T. Abatzoglou, Maxwell B. Joseph, Michael J. Koontz, Adam L. Mahood, Joseph McGlinchy, Megan E. Cattau & A. Park Williams
Nature
This study predicts that continued night-time warming owing to anthropogenic climate change will promote more intense, longer-lasting and larger fires.Read More →
