Carbon dioxide, the most important man-made greenhouse gas, gets most of the attention in efforts to stem the effects of climate change. While methane is considered a much more potent greenhouse gas, ...

A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight ...

Environmental Studies Professor Sikina Jinnah was a co-author on a new report from the National Academies of Sciences, Engineering, and Medicine (NASEM) that recommends a national research agenda for ...

Global surface temperatures have risen by 1.1°C relative to preindustrial times, predominantly due to anthropogenic greenhouse gas (GHG) emissions (IPCC, 2021). Methane (CH 4) emissions from human ...

Atmospheric scientists show proposed 'geoengineering' effort to remove methane, a potent greenhouse gas, from the atmosphere could worse air quality while providing minimal climate benefits. As the ...

Icy chunks of frozen methane and water are not responsible for the periodic increases in atmospheric methane recorded in Greenland ice cores, according to a Penn State geoscientist. The ice core ...

A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight ...

This study will consider the need and viable options for atmospheric methane removal--one category of "negative emissions technologies" currently being explored as part of efforts to achieve net-zero ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to “geoengineer” climate-saving solutions, that is, alter the atmosphere at a global scale ...
