African Rice Cultivation Linked to Rising Methane

January 2024
Zichong Chen, Nicholas Balasus, Haipeng Lin, Hannah Nesser, Daniel J. Jacob
Nature Climate Change
In this peer-reviewed article, the authors assess methane emissions from rapidly increasing rice cultivation in Africa. The authors estimate that this source accounts for 7% of the current global rise in methane can be attributed to this source.Read More →

Geostationary Satellite Observations of Extreme and Transient Methane Emissions from Oil and Gas Infrastructure

December 2023
Marc Watine-Guiu, Daniel J. Varon, Itziar Irakulis-Loitxate, Nicholas Balasus, Daniel J. Jacob
Proceedings of the National Academy of Sciences
In this peer-reviewed study, the authors use continuous 5-minute monitoring of large methane point sources with geostationary satellites to document and quantify large methane releases from oil and gas infrastructure.Read More →

A measurement-based upstream oil and gas methane inventory for Alberta, Canada reveals higher emissions and different sources than official estimates

November 2023
Bradley M. Conrad, David R. Tyner, Hugh Z. Li, Donglai Xie, Matthew R. Johnson
Nature Communications Earth & Environment
This peer-reviewed study presents a methane inventory for conventional upstream oil and gas operations in Alberta, Canada, and finds that asset-level methane emissions are approximately 1.5x the federally reported levels.Read More →

Extratropical forests increasingly at risk due to lightning fires

November 2023
Thomas A. J. Janssen, Matthew W. Jones, Declan Finney, Guido R. van der Werf, Dave van Wees, Wenxuan Xu, Sander Veraverbeke
Nature Geoscience
In this peer-reviewed study, the authors examine fire ignition, and show that 77% of the burned area in extratropical forests stems from lightning. These areas are expected to experience between 11 and 31% more lightning per degree of warming.Read More →

Mercury and CO2 emissions from artisanal gold mining in Brazilian Amazon rainforest

November 2023
Benjamin Fritz, Bernhard Peregovich, Lorena da Silva Tenório, Adria Cristina da Silva Alves, Mario Schmidt
Nature Sustainability
In this peer-reviewed study, the authors investigate the use of mercury and energy at artisanal gold mining sites in Brazil, and assesses the mercury and CO2 emissions associated with this sector of the informal economy.Read More →

Built structures influence patterns of energy demand and CO₂ emissions across countries

July 2023
Helmut Haberl, Markus Löw, Alejandro Perez-Laborda, Sarah Matej, Barbara Plank, Dominik Wiedenhofer, Felix Creutzig, Karl-Heinz Erb, and Juan Antonio Duro
Nature Communications
This peer-reviewed study uses statistical analysis to analyze the correlation between patterns of settlement and transportation infrastructures on per-capita energy demand and CO₂ emissions at the national level.Read More →

Excess methane emissions from shallow water platforms elevate the carbon intensity of US Gulf of Mexico oil and gas production

April 2023
Alan M. Gorchov Negron, Eric A. Kort, Yuanlei Chen, Ángel F. Adames-Corraliza
Proceedings of the National Academy of Sciences
This peer-reviewed study presents an approach to calculating the carbon intensity of oil and gas production in the Gulf of Mexico, finding that government inventories underestimate the amount of methane produced by these operations.Read More →
