Most striking is the fact that each record reveals that the 20th century is the warmest of the entire record, and that warming was most dramatic after 1920.

So, by studying the crust of the Earth, we can estimate global weather conditions going back at least 1000 years. I would tend to think this is more evidence of a trend than 1, or 2, or even 10 years in any specific point.
And just to clarify, if the Earth's temperature rises very much at all, very quickly, we also know through fossil evidence that this can cause -mass extinctions-. That is to say, entire food webs can collapse, and this can very profoundly effect the prosperity of the human race. You don't have to give a damn about those other species - beyond the fact that your very existence, in some way is reliant on the great majority of them, and the content of their life-cycle. |
WHAT!?!?
Where's your data for the last 3 hours? It dropped a couple of degrees here at my house in tha time alone. that's HUGE relative to the magnitude of change those quack scientists blaber on about. GLOBAL WARMING IS A SHAM!!!
