Even right-wingers who know that "global warming" is a crock do not seem to grasp what the tree-huggers are demanding. Liberals want mass starvation and human devastation.
Forget the lunacy of people claiming to tell us the precise temperature of planet Earth in 1918 based on tree rings. Or the fact that in the '70s liberals were issuing similarly dire warnings about "global cooling."
Simply consider what noted climatologists Al Gore and Melissa Etheridge are demanding that we do to combat their nutty conjectures about "global warming." They want us to starve the productive sector of fossil fuel and allow the world's factories to grind to a halt. This means an end to material growth and a cataclysmic reduction in wealth.
There are more reputable scientists defending astrology than defending "global warming," but liberals simply announce that the debate has been resolved in their favor and demand that we shut down all production.
