Two things here, actually. One is, the jury is still out on the overall long-range trend toward higher global temperatures. And the second is, what, if any, effect does human activity have on climate change? THE EARTH DOES NOT CARE!! This planet has been both much hotter, and much colder, in the past, than it now is, and somehow, life has adapted.

Life has adapted but not necessarily human life. And the adaptation has often been very, very painful.
