Just this week I read a 1975 article from Newsweek Magazine warning about the impending disater of global cooling. It's the same hysteria we have now except in reverse. Temperature changes/fluctuations are not unusual over time. How did glaciers come and go otherwise? I think anthropomorphic global warming is a racket although the sun is no doubt getting warmer. The political and financial motivations  of GW are pretty clear and scaring young kids is pretty lame. 
From Newsweek:
"The Cooling World" - by Peter Gwynne 
 
"There are ominous signs that the Earth's weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production -- with serious political implications for just about every nation on Earth. The drop in food output could begin quite soon, perhaps only 10 years from now.
    The regions destined to feel its impact are the great wheat-producing lands of Canada and the U.S.S.R. in the North, along with a number of marginally self-sufficient tropical areas -- parts ofIndia,Pakistan, Bangladesh, Indochina and Indonesia -- where the growing season is dependent upon the rains brought by the monsoon.
    The evidence in support of these predictions has now begun to accumulate so massively that meteorologists are hard-pressed to keep up with it...
To scientists, these seemingly disparate incidents represent the advance signs of fundamental changes in the world's weather. Meteorologists disagree about the cause and extent of the trend, as well as over its specific impact on local weather conditions. But they are almost unanimous in the view that the trend will reduce agricultural 
productivity for the rest of the century. If the climatic change is as profound as some of the pessimists fear, the resulting famines could be catastrophic. ?A major climatic change would force economic and social adjustments on a worldwide scale,? warns a recent report by the National Academy of Sciences, ?because the global patterns of food production and population that have evolved are implicitly dependent on the climate of the present century...
Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects. They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve. But the scientists see few signs that government leaders anywhere are even prepared to take the simple measures of stockpiling food or of introducing the variables of climatic uncertainty into economic projections of future food supplies. The longer the planners delay, the more difficult will they find it to cope with climatic change once the results become grim reality."

It's almost funny educated people can be so taken in by this hysteria. Climatologist, Roger Pielke Sr. at the University of Colorado sums it up well: 
"Let's just say a crowd of baby boomers and yuppies have hijacked this thing," Gray says. "It's about politics. Very few people have experience with some real data. I think that there is so much general lack of knowledge on this. I've been at this over 50 years down in the trenches working, thinking and teaching." 
Gray acknowledges that we've had some warming the past 30 years. "I don't question that," he explains. "And humans might have caused a very slight amount of this warming. Very slight. But this warming trend is not going to keep on going. My belief is that three, four years from now, the globe will start to cool again, as it did from the middle '40s to the middle '70s." 
Both Gray and Pielke say there are many younger scientists who voice their concerns about global warming hysteria privately but would never jeopardize their careers by speaking up. 
"Plenty of young people tell me they don't believe it," he says. "But they won't touch this at all. If they're smart, they'll say: 'I'm going to let this run its course.' It's a sort of mild McCarthyism. I just believe in telling the truth the best I can. I was brought up that way." 
So next time you're with some progressive friends, dissent. Tell 'em you're not sold on this global warming stuff. 
Back away slowly. You'll probably be called a fascist. 
Don't worry, you're not. A true fascist is anyone who wants to take away my air conditioning or force me to ride a bike. "
