Are we heating up or cooling down? Here's a 1974 Time Magazine article that tried to scare us.
Here's my favorite paragraph from that story and the reason why I shut out the noise about the current global warming debate:
"Whatever the cause of the cooling trend, its effects could be extremely serious, if not catastrophic. Scientists figure that only a 1% decrease in the amount of sunlight hitting the earth's surface could tip the climatic balance, and cool the planet enough to send it sliding down the road to another ice age within only a few hundred years."
That's what many scientists believed just 35 years ago. Pssst! Here's a little secret from me to you, they don't know what is happening. They are just guessing. I'm all for saving energy and recycling, etc., but don't do the scare stuff, it's silly. Remember Y2K? Another media scare that fizzled.
Besides I enjoy driving my gas guzzling Chevrolet Tahoe. When Al Gore gives up his private jet and energy inefficient home, I'll think about down sizing my travel mode.
