Selling Global Warming seems to even harder than selling Darwinism (do we have a forum for that too?). It's taken 2000 scientists a few years to come to the conclusion that human beings are at least largely responsible for the climate changes. I suppose, if we feel inclined to, we can ignore them and try to analyse the whole thing ourselves; and when that's done do it again, just to be sure; and again - by which time we may find that the process is irreversible, and dear ol' planet Earth is on it's way to becoming another Venus.
