Why are those who believe in a deity dismissed as morons, but those who believe in Global Warming are regarded as infallible?

Since the time of Abraham and Moses, there has been an argument about the existence of a supernatural deity.

I am atheist, but I appreciate the passions of this debate. In spite of science, people tend to believe what they believe. So be it. It has gone on “forever”. And nobody is winning the argument. Even now, after a few thousand years, the issue is unresolved. And the argument is costly in human terms, no doubt.

On the other hand, the anti industrial revolution, the germ of the environmentalist debate, is relatively young.

It is only a couple of centuries old. And yet, the proponents of global warming, the current edition of the anti industrial revolution, want their point of view to be accepted NOW. It seems to be a waste of time to them to work through the debate as the deists have done and continue to do.

They believe that they are more special than than the folks who have argued the principle of deity for centuries, and done a reasonable job of hanging on.

What makes the the Global Warming crowd (relative infants) more important than the God Exists crowd (relative veterans to combating skepticism)?
