Methane Emissions Soared to a Record in 2021, Scientists Say

Ranges of methane within the ambiance elevated final yr by the biggest quantity since measurements started 4 a long time in the past, authorities scientists mentioned on Thursday, including to issues in regards to the planet-warming fuel, which spews from oil and pure fuel operations.

Methane is much less plentiful within the ambiance than carbon dioxide, however it’s stronger in its near-term results on international warming. Massive quantities of methane pour into the air from wells and pipelines, typically via unintentional leaks. Different sources embody livestock, landfills and decaying natural matter in wetlands.

Atmospheric concentrations of methane have elevated steadily over the previous decade, and in 2021 they rose by a document quantity over the yr earlier than, reaching a brand new excessive, in response to evaluation by the Nationwide Oceanic and Atmospheric Administration. The earlier document for annual improve in methane ranges had been set in 2020.

“Our information present that international emissions proceed to maneuver within the flawed course at a fast tempo,” mentioned Richard W. Spinrad, the NOAA administrator. “Decreasing methane emissions is a crucial software we are able to use proper now to reduce the impacts of local weather change within the close to time period, and quickly cut back the speed of warming.”
