I have a degree in postmortem science and hobby in anthropology/archeology/paleontology. The biggest extinction event this globe has ever seen, the Permian Extinction, where over 90% of ALL life (96% of ocean life) went extinct, was from pollution and a mere 10°C increase in global temperature. That's all it took to decimate life on earth. The pollution and heat came from volcanoes, but we are on the same path. It's already gone up 1.6°C... I do think humanity will survive, but not the majority of us.
Some of my family doesn't believe in climate change, and/or is religious to the point that they don't believe in carbon dating and core sample data. I wish I could make them believe, but no data in the world will work.
I was part of a documentary on the largest fires in recorded history and so many were within the last 10 years it was terrifying. One in the forests of Russia was still ongoing when the doco was finished and RELEASED!
I understand the term isn't always used in such a way, but there is something of irony to hear the term decimate (to kill 1 of every 10 people) to describe what you are saying that only 1 in every 10 survived.
