What if its not a simple equation. Most multiple regressions are not simple equations. Why should we choose to believe that the rise in tempatures over the last 150 years is the result of increased greenhouse gas emissions over the last 50 years...

Don't get me wrong. the greenhouse effect MIGHT be real. But its also equally possible that the recent rise in tempatures is something completely unrelated to CO2 in the atmosphere.

Your article stated that there has been a std. error of 14 degrees over the last 200,000 years. And then it goes on to say that a 1 or 2 degree increase ( if were talking 200,000 years, could this be a sample sample varience? Or maybe there is a bias in the sampling data?) over the last 40 or 50 years as a sign of impending doom.

I just don't buy that we need to change our way of life or were all dead...
