Umm, even if climate change were to actually be not by the fault of humans: It still means we're screwed according to our statistics, and instead we are simply incapable of stopping it.
I don't think people understand how non-permanent the human race is. Even if we manage to win the game and survive to what, the year 3,000,000,000, all of the stars in the universe will eventually burn out, and as we sit, huddled next to the last burning star, harvesting as much heat and light as we can, the human race will come to an end.
