I remember there was a lot of talk about global warming while I was in elementary school. That was the early 90s. Talk about it fizzled really until recently with all the bizarre, or what seems to be bizarre, weather. What makes me quizzical is the fact that historically, the earth has seen weather like this -- and worse -- without all the technologies and industries of mankind.
It seems to me that the scientists have pushed the phenomenon aside and environmentalists have taken up the banner in their stead. Not to knock the efforts of such groups -- but I just don't believe there's some gaping hole in our atmosphere getting wider and wider because we're breathing too much and letting off too much gas.
