They found that the largest contributor to the 2019–24 rise (an increase of 59%) is simply momentum. By 2019, the world was ...

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 ...

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 ...

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 ...

Emissions of methane, a greenhouse gas several times more potent than carbon dioxide, increased at record-high rates between 2020 and 2022. A new study suggests that rather than fossil fuels, microbes ...

In the spring of 2020, as the COVID-19 pandemic brought global industry and travel nearly to a halt, satellite sensors recorded a dramatic plunge in nitrogen dioxide, a byproduct of internal ...

IMAGE: Methane in a planet’s atmosphere may be a sign of life if nonbiological sources can be ruled out. This illustration summarizes the known abiotic sources of methane on Earth, including ...

Methane emissions over India are lower than what is reported in some widely used global emission inventories, according to a study, stressing the need for a stronger monitoring network. Strikingly, ...
