I still think many models are missing volcanic winters. We know they have crazy cooling effects, but they are something we don’t yet control.
More $$$ money needs to go into Vulcanering. Crazy, but if we can make ash spread 20% more that’s years of cooling.

- korpiq 7y agoIf I understand correctly, currently anthropogenically accumulated extra CO2 takes some hundreds of thousands of years to return to geological circulation, while the faster biological circulation won't withhold it all, and seas are getting saturated (and will acidify beyond supporting current lifeforms in the process). [see eg. Hot Earth Dreams] Also, if I understood correctly a single article I'll try to dig up a link to later, the kickback effect of stopping a temporary cooling measure and returning to the warming trend caused by the CO2 still in air will have stronger harmful effects. If these hold, it might prove tricky to keep up a moderate, safe cooling effect long enough, even if some technical measure to cause volcanic winter was found.
