Environmental movements around the world are committed to global warming hysteria and nowhere more so than on college and university campuses, where they can harass those who say otherwise. One of the scientists interviewed on the British documentary reported getting death threats.

In politics, even conservative Republicans seem to have taken the view that, if you can't lick 'em, join 'em. So have big corporations, which have joined the stampede.

This only enables the green crusaders to declare at every opportunity that "everybody" believes the global warming scenario, except for a scattered few "deniers" who are likened to Holocaust deniers.

The difference is that we have the hardest and most painful evidence that there was a Holocaust. But, for the global warming scenario that is causing such hysteria, we have only a movie made by a politician and mathematical models whose results change drastically when you change a few of the arbitrarily selected variables.

No one denies that temperatures are about a degree warmer than they were a century ago.

What the climate scientists in the British documentary deny is that you can mindlessly extrapolate that, or that we are headed for a climate catastrophe if we don't take drastic steps that could cause an economic catastrophe.

"Global warming" is just the latest in a long line of hysterical crusades to which we seem to be increasingly susceptible.
