Sea 'Boiling' with Methane Discovered in Siberia

Geoengineering is really the only realistic option if this is the case.

Sulfate aerosol injection is by far the most promising. And cheap - maybe 5-8b per year [1]. I'm not claiming this is a good idea in any way. As they say: desperate times call for desperate measures. We could buy ourselves several decades to sort our (as humans) shit out. We don't understand the unintended consequences very well, but at least this technique mimics natural processes (volcanic eruptions).

I've a hunch that a Lagrange point sun shield is becoming quite affordable with recent reductions in cost of launching to space. A sunshield consisting of many self orientating mirror bearing craft would have the advantage of being able to be quickly attenuated if required, even filtering more or less light on particular continents or weather systems.

It could win you some time to resolve real issues, wont work as permanent solution as stopping would have quick devasting results.
