Cued up by Jay Leno on Tuesday's Tonight Show to deliver some quips about global warming, Dennis Miller did some show and tell as he reached behind his chair for a hard copy of the April 28, 1975 Newsweek. That's the edition often cited by doubters of dire global warming predictions because its story, “The Cooling World,” illustrates the fickle nature of media-fueled hysteria. Miller explained that “I had heard about this on the Internet, Jay, and I went back and got a copy of it. It's a Newsweek magazine” with “The Cooling World” as “the big story in the 'Science' section.” Miller pointed to a chart on the page showing “the temperature of the planet is dropping off” and he marveled at how “it says the solution to the global cooling problem is to deliberately melt the polar ice caps” -- the very phenomenon now cited as proof of global warming.
