Again, another study about global warming that spend more time talking about the hypothetical cause and effects rather than how the model was validated, proving its fossil fuels causing global warming. This does not help their cause. Either that or supply the validation methodology.

Its not if the burning of fossil fuel made global warming happen of not, its if reducing its emission will help reduce the effect. Just because humans may or may not have caused it, certainly does not mean we shouldnt try everything in our power to reverse the process.

There is sufficient proof that global warming is occurring. There is sufficient proof that anthropogenic gases contribute to closing the radiation window that governs heat loss from the earth's atmosphere. There is also sufficient evidence that there are insufficient fossil energy resources to continue consuming them at the current per capita energy rates for 300 years. Better to look at the bigger picture.

Your (or whoevers) prediction of 300 years is as accurate as many that have gone before ... and actually more optimistic! There have been predictions of fossil fuel depletion since the late 19th century. In the thirties, the prediction was 30 years. One of the latest was Jimmy Carter (1978?) saying oil supplies if consumed at 'current rates' would be depleted by EARLY 90's. In high school in the sixties we were told 50 years. Yes, a finite amount. But I'll bet you a buck, there will be a glut of black goo in the ground long after alternative sources of energy are found leaving the goo just that ........ goo.

Furthermore ............. the big picture will be AT THAT TIME (long after clean energy sources are used) the fact there will remain global warming at the same rate as we see now. Will the explanation be at that time ........... we broke the ecosphere for good?

If you want to work on reversing what is happening ............ please, drive your SUV over to the nearest geophysics lab and beginning working on why the earth has undergone such wide-sweeping climactic changes throughout its history (long before we began the systematic depletion of fossil fuels).
