Google the work of Dr. Guy McPherson (https://www.youtube.com/watch?v=QPDpJxg2lwg) and weep. The evidence of self-accelerating, feedback-driven global heating and destabilization of the climatic norms of the last 8-900 thousand years that enabled the biosphere and humanity to thrive is simply overwhelming.

The climate crisis arises from a spike in CO2 concentrations to the highest level in 3 million years--all within the geological eyeblink of 150 years, due to the global expansion of fossil-fuel driven industrial society. No living organisms or ecosystems can adapt to change that rapid and self-accelerating!
