If you weren't so depressing ignorant, you'd be aware that that the Milankovitch orbital perturbations that seem to have been driving the recent alternations between Ice Ages and interglacials need quite a lot of positive feedback to generate the observed perturbations in global temperature http://www.globalwarmingart.com/wiki/Wikipedia:Milankovitch_cycles Global temperatures go in for self-exaggeration rather than self- correction. Happily, we've already melted most of the snow cover off the top of the northern hemisphere so that particular positive feed-back mechanism is disabled, but the geological record strongly suggests that there are others waiting to kick in when we get the atmospheric CO2 levels high enough. The end-Permian mass extinction took place a long time ago, but it has been demonstrated that one of the activities going on around that time was massive vulcanism erupting through coal beds, which seems to have been nature's way of digging up a lot of coal and burning it http://en.wikipedia.org/wiki/Permian%E2%80%93Triassic_extinction_event -- Bill Sloman, Nijmegen

You are overemphasizing the political aspect of US ethanol production. In summer, regulations (EPA, etc.) require lower emission fuels, and 10 percent ethanol is one way gasoline is blended for big city use. Also, to reduce oil imports, a long term project of ethanol (from sugar, not corn) is important. In case of corn shortages, ethanol plants can be closed, which is a much better situation that the existing problem with rice, which will become a real bad problem for people unable or unwilling to switch to a lower cost or more plentiful staple food. Rice farmers are leaving the farms and going into other, higher paying and less labor intensive jobs, and people will suffer.

Stick to the point.
