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 ...

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, ...

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 ...

Researchers turned to "clumped methane isotopes," a rare form of methane in which two heavier atoms occur in the same ...

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 ...

Methane is one of the most powerful greenhouse gases, significantly contributing to global warming. It also affects the formation of other climate-relevant substances like ozone and water ...

Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30 ...

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 ...

A study explores effects of Saharan dust clouds on atmospheric methane. Its findings have potentially far-reaching implications for understanding the global methane budget and reasons behind the ...

A gigantic underwater volcano became a massive chemistry experiment that could help researchers quantify the success of tactics designed to tackle climate change. In January 2022, the Hunga ...
