Let's put it in my perspective. Will CO2 trap solar heat, yes a little. Water vapor, methane, ozone friendly gases, do a lot more. I don't believe CO2 is the main culprit. I think warming is natural, just like the cooling in the 70's, and the warming that started back 120 years ago, and the much warmer period 1000 years ago, and the ice age 50,000 years ago, and the hundreds of cooling and heat trends that have happened since then.
The great unwashed masses like a good story of gloom and doom. Global warming will be bad, global cooling would be much much much worse. We happen to be lucky enough to live in a warming period.
I really think that changes in land cover, city, deforestation, erosion into water bodies, forest fires, and dark particles from plowing and everything we humans move around is going to end up being the biggest single factor.
But, it's not sexy, or liable. So, Al Gore needs to be president of the universe, so he's spinning a yarn that scares the little children more than a promise of eternal damnation. Welcome to the next new religion. You just have to believe. Have Faith in Gore.  |
