Iono. The fact that tropical plant and animal fossils are found in arctic zones, as well as atop mountains, indicates some pretty drastic climate changes have already taken place.
I presume dino factories, dino cars, and the lavish dino style of living created the dinogenic climate change the dinosaurs put their world through. Sadly, the dino deniers didn't listen to the dino warmers.
Also, something needs to be done about the sun and volcanos as they simply have too much control over our climate, perhaps a tax or other regulatory measure?
