If humanity wants to know what is ahead in terms of tossing gigatons of CO2 and methane into the global atmosphere, all one has to do is look into geological history. There are at least two geological extinction events that mimic pretty closely what is happening now, and the record is very clear what happens next.
The clarity of the PROOF that humanity has triggered a third mass extinction event is REALLY CLEAR.
Unless humanity learns how to think in terms of what works for 7 future generations without causing harm, extinction is dead ahead, with an emphasis on ‘dead’.
