I no longer worry. I'm extremely pessimistic about the impending climate change. I believe Sabine isn't pessimistic enough about what to anticipate. Consider the tundra methane emissions and the explosive release of methane-hydrates from the oceans, along with water vapor, a potent greenhouse gas. The disaster looming over all ecosystems (a mass extinction event) that will happen in decades and the doom-phase could last for 200,000 years. The chances of humanity surviving are incredibly slim, IMO. We can't colonize Greenland or Antarctica due to the lack of fertile soil, and it would take thousands of years to develop it. Without saying so, we don't have this amount of time.

Climate change is a catastrophe, but it's not going to be the apocalypse and if we keep working on mititgation, there is a good chance it will merely be a "normal" scale disaster.

For example - it's possible that tundra methane emissions in many areas could be mitigated relatively quickly by the regrowth of birch and pine scrubland whose increased evapotranspiration will reduce water tables and eliminate methane emissions. And aboveground carbon sequestration in woody tree mass could outweigh losses from belowground oxidation. This already occurs in fenlands in Southern Finland (paper I read)

We don't know enough about methane hydrates to assess their stability.

Many ecosystems will be reasonably resilient to climate change - maybe up to 2/3 of them, although some specific species groups like tropical amphibians are going to have a really bad time.

What was that story about a frog which was slowly boiled in a pot and didn't know it about it until it was too late?

Funny how everyone always leaves out the part where in the original experiment, said frog's brain was removed before putting it in the pot :)

Well that only makes it even more relevant.
