re:Hmmm....isn't it odd that the earth starts to heat up just as the industrial revolution gets underway and that CO2 levels in the atmosphere now far exceed the norm established for thousands....wait, I think its millions of years. Making shit up again - over last millions of years the level of CO2 has averaged 1500 ppm and as high as 7000 - but now it's around 350 which is rather low. geocraft.com That's right I misspoke.....I should have stopped at hundreds of thousands of years, not millions: Carbon dioxide level highest in 650,000 years news.mongabay.com For 650,000 years, CO2 levels were in a tight range between 200-300 PPM. Suddenly, shortly after the start of heavy industrialization of the earth, CO2 concentrations began to rise quickly, breaking out of previous range in 1900. It doesn't take a scientist nor a genius to figure out that something not so good may be happening. Certainly, we should be more than a little concerned.....but not your Mr. Bush. And its closer to 380 PPM than 350 PPM.
