I'm not denying climate change, but that's... a bit hyperbolic, with a bunch of silly absolutes. Mass death everywhere? Wildlife is thriving in the Chernobyl exclusion zone.[1] The world has been getting greener with more plant life because of the increased CO2 in the atmosphere.[2]

Total ecosystem collapse? Which ecosystem? Why? Again, I'm not denying any of the human impact to our climate, and I agree that many ecosystems will change, and it will be our fault, but I don't think it's productive or healthy to think of it with such bleakness.
