More of the horrible climate demagoguery and indoctrination by the AAAS! Again junk science and junk journalism?
Remember CO2 and methane are trace gases in the atmosphere measured in few hundred (CO2) or even few (methane) parts per million!
I bet there also arsonists in Siberia! Or is Putin the Terrible doing some deforestation in Siberia so the megalomaniac can finally conquer the rest of the world? 😊
"Northern hemispheric permafrost stores twice as much carbon as is found in the atmosphere. As permafrost thaws due to climate warming, it becomes a potential source of methane emissions caused by microbial decomposition of soil organic carbon in wetlands, which could cause further warming. Zhu et al. report that methane emissions in Siberia have increased at a rate of around 5% per year since 2010 due to a combination of fires and permafrost melting. This source of methane is projected to become more important as climate continues to warm."
From abstract:
"The northern permafrost region, which stores double the amount of carbon in the atmosphere, is vulnerable to accelerated warming.
Methane emissions from thawing permafrost may eventually result in a climate-carbon feedback.
Our analysis of atmospheric methane data shows that Siberian growing-season methane emissions have increased by 12.0 ± 1.9 teragrams of methane (TgCH4) (5% per year) over the period 2010–2023.
We reveal contrasting Siberian hydrological trends linked to high-pressure systems and distinct air-sea-land interactions.
Warmer, drier conditions over eastern Siberia enhance fire-related emissions (0.7 ± 0.1 TgCH4 year−2), and wetter conditions over western Siberia promote wetland-related emissions (0.4 ± 0.1 TgCH4 year−2).
Weakly nonlinear relationships between temperature maxima and emissions suggest that by 2050 [???], higher Siberian emissions could offset about 20% of the global methane reduction required for climate targets [???], with eastern Siberia dominating the projected increase."
