"Remember the exhortations about the coming 'nuclear winter' about 30 years ago? Simply another fad theory."
I remember that. I also remember Carl Sagan saying that if Saddam set the oil fields on fire it would cause global cooling and other terrible things. I seem to remember the oil fields being on fire and other than wasting a bunch of oil and causing Boots and Coots to make a bunch of money nothing much happened. It sure didn't cause global cooling, at least not yet. I wish we could hear what Carl would say now, I just wonder if he'd admit he was wrong.
I believe someone once figured that any major volcano eruption puts more carbon and gasses into the air than the Iraqi oilfields for example.
It's not nice to mock Mother Nature. Man can't alter the magnetic field--but she's in the throes of doing that right now. We're like the rooster that crows at the Sun every morning, sure that he's responsible for its appearance.
