I was reading somewhere that we are already fucked even if we were to completely halt greenhouse emissions today. Apparently we kickstarted some positive feedback loop (I think it was the thawing of the permafrost in Siberia/Canada) which releases enormous quantities of Methane and that with the higher temperatures we already reached we decreased Earth albedo as there is less snow/ice reflecting light into space.

I really hope that particular article was wrong, because the alternative is that we have to resort to geo engineering. Considering that the governments can't really coordinate in preventing this, I don't see them coordinate in fixing it, especially because the scale and costs of the "fixes" are astronomical.

There's an old joke that goes about like:

How do you solve Global Warming? Nuclear Winter ...

I really hope this is not how we end up geo-engineering our way out of Climate change.
