Reply #19: I read a report once

That said the Earth has always had colder periods and hotter periods throughout its history, and they can last for varying amounts of time. It suggested that we're just in a hotter period right now, and that things would eventually cool off again. This was substantiated by rock formations that indicated the temperature cycle differences throughout history.

It's been a while since I read it, but it suggested that even with the ozone issue, this cycle was necessary for the Earth to survive, and that it would repair itself and cool off again, as it has done many times before. These cycles can last hundreds of years, and evolve slowly.

I have no idea how credible it was, seems a professor wrote it, but it made sense to me at the time.

:o You don't suppose it was Republican propaganda and I bought it do you?!?!?!?!?!
