Extinction caused by "Global Warming"

So, you have a perfectly logical theory for a mass extinction. Lots of evidence to support that theory (a meteor crashing to earth) and recent new findings that make it more and more likely. And in addition, the same theory can explain subsequent extinctions like that of the dinosaurs. But another theory is out there which has political aspirations. For the sake of argument, we'll call this theory "global warming." The theory is having problems (for instance, a recent piece by respected author Michael Crichton assaulting the science behind it) and its political support is waning. So what is the logical way to go? You conclude that "global warming" must be the right theory for both the past and the future, of course!



C'mon, people. Science is science, and politics is politics. Let the scientists decide on the science, and let the politicians argue out the rest.
