jake-the-peg � Sorry but you are wrong. If you look at the climate record for the last 400 thousand years, the Earth has gone through many warming and cooling phases. This is entirely natural.
You ask many questions and post many sources so to answer all of those questions would take many pages of text. If you really want them, I�ll do my best to point you in the right direction.
The fact is that Global Warming, if it is happening at all, is nothing to do with humans.
There have been many periods in recent (ie. geologically recent) history where the global temperature has been as high as 5 degrees higher than today. Did polar bears die out? Obviously not because they are still with us today.
Earth�s history tells us that for over 90% of the time it was colder than today, and mostly much, much colder.
Rising and cooling of temperature is a natural effect and is not a result of human activity.
Unfortunately, I think you�ve been hoodwinked by the mainstream media. The scientific data is unequivocal � rises in CO2 have nothing to do with so called global warming.
