*That's a huge oversimplification of the models and the real world. On the other hand, maybe it is the first order explaination of why CH4 and CO2 are so closely linked?

Thomas Bauska @tinyicybubbles.bsky.social · 24/03/2026
If they forced both their climate and LAND CARBON models with ~>400 ppm there are a couple circularities that are probably impossible to disentangle. To simplify for Bluesky*: Higher CO2 -> Higher NPP -> Higher CH4 emissions. Would really need to run the models again with lower CO2 but elevated T.
