Hilarious. American attitudes on global warming are unchanged over the past 19 years:

While 61% of Americans say the effects of global warming have already begun, just a little more than a third say they worry about it a great deal, a percentage that is roughly the same as the one Gallup measured 19 years ago.

I guess this makes global warming a “tangential” issue and the Left should be outraged if it’s ever mentioned in a debate.
