A new study, published Monday in Frontiers in Science, found that methane emissions have risen quickly since 2006, with the growth rates for atmospheric methane seeing an "abrupt and rapid increase" in the early 2020s.
Key message remains that methane is “the strongest lever we can quickly pull to reduce warming”.
It’s not runaway, but there is a positive feedback of methane increasing its own lifetime by using up atmospheric oxidising capacity.
I note also, new to me - “an increase in decomposition rates from wetlands as higher temperatures interacted with La Niña conditions in the tropics” - so during El Niño we get more CO2 from forest fires, but during La Niña more CH4 … - how to lock-in that carbon ?
I also wonder how much methane is coming from Russia recently, whose government cares the least of all.
