Variations in the sun's radiation have long been pointed out by some as a possible cause of global temperature fluctuations. Now, this Reuters article at CNN describes a new study that discounts this solar hypothesis. quote:
Researchers from Germany, Switzerland and the United States found that the sun's brightness varied by only 0.07 percent over 11-year sunspot cycles, far too little to account for the rise in temperatures since the Industrial Revolution.
By discounting solar variation as a contibuting factor, this study adds further support to the prevailing scientific view that the carbon dioxide produced by the burning of fossil fuels is the main cause of global warming.

I suppose it's good to see that some hypothesis about global warming are being put to rest, but the ice core samples make it very clear that the amount of carbon dioxide in our atmosphere today is *significantly* higher than it's ever been. Humans are definitely having a major inpact on the environment. If we don't do something about it soon, and we don't wean ourselves off of fossil fuels, it's going to become a critical problem. |

Indeed, indeed.
I have read that it's already too late to stop or even slow the cycle. Don't know if that's entirely accurate, but what the hell. It certainly wouldn't hurt to radically cut down on our emissions.
