of course it isn't a crude attempt to shut down debate.

The debate over the extent global warming is exacerbated is one to be had. But to say global warming doesn't exist is to say the earth is flat.

Now.. I will enjoy debate with flat earth dudes but all them time I will be pointing and laughing. the same with global warming. it exists, so no debate needed for the principle, but a hell of a lot for the detail.

Can't argue bollocks, you just end up with both sides talking bollocks. And for once, I have fact on my side. I intend to enjoy such status.
