Nope, the extreme Global Warming we see today wouldn't have happened without human activity. It happens faster and with far more powerful consequences compared to «natural variations». This solemn and obvious truth only rejected by dumb and greedy jerks should have made us change our lives in fundamental ways. We must change society completely, in a way far more favorable to nature. We should have done so long ago. As it is now we are pretty much like the elephant in a china store, ruining everything, including our own means of survival. We commit collective suicide. And not just because of the human created climate change, but due to virtually all minor and major decisions we make or don’t make.
