Hmmm. I may be a simple man..but my take is this.
The Earth has warmed and cooled many times over Eons. Allegedly it was warmer during the "Dark Ages" than it is now.
Greenland has Archeological digs finding farms where ice is now.
I remember in the '70's when the new Ice Age was the big scare. I remember SARS, West Nile Virus, Bird Flu, AIDS, and who could forget...the ozone layer was going to give out and FRY the planet in the next 5 years. Scare mongers I say.
IMHO, it's a cycle. Should we try to be better Shepards of our Planet? Heck ya. But the new "Religion" of global warming is ridiculous.
Take a look at our EPA standards and the rest of the world. We can't pass gas without proper EPA guidlines and inspections restricting our bungholes.
BTW, I have heard that the nasty warming period.. 0.6 degrees over the past 100 years, had stopped in 1998. The global temp has not risen since then, but actually starting to drop.
Snow in Baghdad for the first time in written history this past Winter. Amazing. But not alot of airtime.
