Large increases in methane emissions expected from North America’s largest wetland complex

March 2023
Sheel Bansal, Max Post Van Der Burg, Rachel R. Fern, John W. Jones, Rachel Lo, Owen P. McKenna, Brian A. Tangen, Zhen Zhang, Robert A. Gleason
Science Advances
This peer-reviewed study examines natural methane emissions from the Prairie Pothole Region, North America's largest wetland. These emissions are predicted to increase by 2- or 3-fold by 2100 under moderate or severe warming scenarios, respectively.Read More →

Nature Communications
This peer-reviewed study examines the effect of South Asian black carbon emissions on glacial melt in the Tibetan plateau, and indirect effects of this melt on the supply of water in densely-populated regions of South Asia.Read More →

Atmospheric observations suggest methane emissions in north-eastern China growing with natural gas use

November 2022
Fenjuan Wang, Shamil Maksyutov, Rajesh Janardanan, Aki Tsuruta, Akihiko Ito, Isamu Morino, Yukio Yoshida, Yasunori Tohjima, Johannes W. Kaiser, Xin Lan, Yong Zhang, Ivan Mammarella, Jost V. Lavric, Tsuneo Matsunaga
Nature Scientific Reports
Using atmospheric and satellite observations of methane, this study estimates poorly-measured methane emissions in China, and concludes that China's increased methane emissions are largely attributable to the growth in China's natural gas use.Read More →

Seasonal increase of methane emissions linked to warming in Siberian tundra

October 2022
Norman Rößger, Torsten Sachs, Christian Wille, Julia Boike, Lars Kutzbach
Nature Climate Change
This paper assesses methane emissions from the North Siberian Lena River Delta, providing the first observational evidence of an increasing trend of early summer methane emissions from tundra wetlands linked to atmospheric warming.Read More →

Majority of US urban natural gas emissions unaccounted for in inventories

November 2021
Maryann R. Sargent, Cody Floerchinger, Kathryn McKain, John Budney, Elaine W. Gottlieb, Lucy R. Hutyra, Joseph Rudek, and Steven C. Wofsy
Proceedings of the National Academy of Sciences of the United States of America
This study concludes that consumption-driven methane losses, such as in transmission or end-use, may be a large component of emissions that is missing from inventories.Read More →
