I agree that global warming is a problem right now with storms and flooding but does that hold in the looong run? I mean earth has apparently been cooling down since millions of years and the biosphere could benefit from some temperature increase, or do I read this wrong?:

(yes that might be looking into the future/past too far, but we are in a crazy idea thread, or not?)
Rate of change is the big thing, not necessarily absolute level.
The closest analog for what's going on now and will probably continue to go on for ~100,000 years is the Paleocene-Eocene thermal maximum (PETM) https://en.wikipedia.org/wiki/Paleocene%E2%80%93Eocene_Thermal_Maximum . Though we may be altering the atmosphere up to two orders of magnitude faster than that one did.
