Geoengineering is starting to seem like less of a "possibility" and more of a necessity, because self-sustaining methane emission loops seem to have been unlocked in the artic and tropics. So even if we were to magically stop the emission of new carbon, Earth will likely just keep heating up. And yes, it's hard to prove that runaway warming is happening (data is noisy, and the time is short), but the burden of proof imho has shifted to the other side. There is a known mechanism of action for runaway warming, data that fits runaway warming, and no known mechanism of action for natural dampening of that warming. The question at this point seems to be "why woudlnt' runaway warming happen"? This is a good (if pop-sci) overview of the methane problem: https://www.ft.com/content/9ef195d6-dcc3-4378-bb35-2721981d6416 https://www.ft.com/content/9ef195d6-dcc3-4378-bb35-2721981d6...
