Brendy, Thief:

From thermodynamics, I believe I remember that PV=NRT, where N and R are some sort of constants and P is pressure, V is volume and T is temperature. So an increase in T without a change in V must increase P. (Don't ya love it?).

Anyway, my point from listening to all this is that its important to understand, to the best of our abilities, what's going on. The Science article has nothing to do with global warming; that water is heating up in the earth via the geothermal effect. Nonetheless, somehow it has been sited as a definitive source of another example of global warming. This is a common thing to do to support positions, but I don't think its responsible for "those in the know" to allow such things to propogate.

From what I have read, there are many scientists who are critical of the climate change research done to date. Apparently the climatological models are not accurate (this should not be surprising given the accuracy of local weather forecasts) because of the tremendously complex earth system that composes our weather. I remember reports that these predicitve models could not even replicate past weather. Then of course we get into the debate accusing some scientists of working for "big business" versus the scientists protecting their research honey pot by predicting dire consequences that need to be further studied.

Another issue that gives me pause is the natural warming and cooling experienced on this planet over millions of years. We've had ice ages and warming trends completely absent man-made spewings, so what's up with dat?

It bothers me to loudly proclaim an injustice when I don't have a complete view. Or to advocate sweeping social changes that could possibly make no difference.

All that being said, I can agree that humans should carefully evaluate their impact on this fragile planet. A number of fuel options are available and can be applied in a less obtrusive way. From a power perspective, one strategy would be to retire old coal and oil facilities and replace them with new coal and oil facilities utilizing the latest pollution control technology. Also build more Nukes. Such a strategy, implemented on a global basis would do much to reduce a majority of our man-made pollutants.

Peace
