Related to my previous post on the continued (and possibly uncontrollable) rise in atmospheric CO₂ — see https://climatejustice.social/@breadandcircuses/112881241321552998 — is this article on increased methane emissions.
Again, we see that the origin is not only man-made, but also from "natural" sources, which are, of course, a result of anthropogenic global warming. Is some of this now out of control? Are we beyond too many tipping points?
Time will tell...
__________________________
So far in the 2020s, global methane emissions have typically been about 30 million tons higher each year than during last decade, with annual records in methane emissions broken in 2021 and again in 2022. While there is no single clear reason for this, scientists point to a number of factors.
Methane comes from the drilling and processing of oil, gas, and coal, with a boom in fracking causing a rash of new gas projects this century. The gas is also emitted from livestock, primarily through the burps of cows, and increased animal agriculture and expanding rice production have contributed.
Meanwhile, rising global heat is causing the faster decomposition of organic matter in wetlands, thereby releasing more methane.
“The growth rate of methane is accelerating, which is worrisome,” said Drew Shindell, a climate scientist at Duke University. “It was quite flat until around 20 years ago, and just in the last few years we’ve had this huge dump of methane. It’s made the job of tackling anthropogenic warming all the more challenging.”

Researchers call for immediate action to reduce methane emissions and avert dangerous escalation in climate crisis." Below this is a photo of an oil refinery in Scotland.
