Based on information from John Stossel's book "Myths, Lies and Downright Stupidity"
Hardly a day goes by without some kind of warning that mankind's use of fossil fuels is causing global warming.
Stossel looks at the numbers. Half of this century's global warming happened between 1900 and 1945. Stossel asks, "If man is responsible, why wasn't there much more warming in the second half of the century? We burned much more fuel during that time."
According to Harvard astrophysicist Sallie Baliunas, added carbon dioxide helps plants grow. Warmer winters give farmers a longer growing season, and the warming might end the droughts in the Sahara.
There's another consideration. For the past 800,000 years, there have been periods of approximately 100,000 years called Ice Ages, followed by a period of 10,000 years, a period called Interglacial, followed by another Ice Age. We're about 10,500 years into the present Interglacial period, namely, we're 500 years overdue for an iceage.
