I really don't think you understand that global warming is, by comparison to droughts or hurricanes, a climactic change that moves at a much slower pace. There is no sense in which contingent atmospheric conditions - like hurricanes - or seasonal ones - like droughts - can be attributed to global warming. As you say >I cite Rachel's Weekly >The chief scientific debate over global warming is not >WHETHER it will happen, but WHEN its effects will become undeniably >obvious. >reports published by the World Meteorological Organization and the United >Nations stating their consensus belief that the CO2 buildup in Earth's >atmosphere will lead to an average global temperature increase of between >2.7 and 8.1 degrees Fahrenheit during the next century. So what possible bearing a (one-sided) prediction of a temperature change in the next century could have on droughts and hurricanes in this is a mystery. As a real social question, we should look instead at why hurricanes, as largely unavoidable events, have differential effects. Improved building design is the best remedy here. In terms of droughts, anyone really concerned to do something would look at the farming techniques and how they could be improved to accomodate any natural conditions. As to long term climactic trends, they are of course real problems in the long term. The first question I would ask is how the greenhouse effect is expected to interact with the ordinary cycle of natural climactic changes expected? However, I don't suppose that anyone whose principle goal is to wallow in self-pity and angst would have bothered to situate greenhouse gases in the context of real climactic change, when it is so much more fun to extrapolate one trend in isolation from all real conditions. Out of such non-science one can make doomsday scenarios that will satisfy ones chiliastic fantasies.
