The problem, Hippiekinkster, is that you are using "real science" and "basic physics" to try to clarify for the uneducated and Dittoheaded populations why something happens. In my experience, this works as well as attempting to mix oil (knowledge) with vinegar (right-wing politics). I posted last year about 36 cubic miles of antarctic ice mass disappearing as determined by gravity sensing satellites. The response I got was that the satellite measurements were wrong because of issues with computer modelling the results. I spent months trying to get the posters involved to clarify, since I used to build computer models for a living and really wanted to understand their point of view, but they crawled off to sulk and refused the opportunity to face peer review of their vast scientific knowledge. To break it down, if 36 cubic miles of ice melt, it raises the water temperature (think of what happens to the Scotch when the ice cube melts) and allows the earth to heat up. When the earth heats up, some water (say, in the ocean) transforms from a liquid state to a vapor state and enters the atmosphere. This vapor cools to some degree, allowing things like winter to cool it below the triple point of water. When it drops below the triple point, the vapor forms into a water or solid state (rain or sleet/snow, for those playing the home game) which falls on the earth. Two issues come up. 1) Melting water raises water levels and displaces 1 billion people from the coastal cities they live in to other places. But FEMA proved that cities that get sunk by hurricanes (predicted for 20 years prior to it by global warming alarmist types, and responded to as a surprise nobody could have predicted by global warming nay-sayers) can be easily relocated to football stadiums and trailer parks in the middle of nowhere. 2) Human beings can survive in a very narrow range of temperatures. Sure, our military is in 140 degree weather in Iraq, which I imagine they describe as "balmy," but when the average temperature gives us regular temperatures of 160 or 180, people start to die off. I say people, because the people who argue against global warming dont really give a good gawd damn how many frogs or coral reefs or spiders or tree moss or whatever dies off. Sinergy They never can cite any peer-reviewed Science. All they have is BS from shills for Big Oil. And you are right, they don't give a flying fuck about whether their grand-children will have an inhabitable Earth, as long as they keep making money. Their main argument for not doing anything seems to be "it'll hurt the economy". Ummmm, if drastic measures aren't taken, there won't BE any economy. Duh. How dumb can they get? Back to water vapor, the more water vapor in the atmosphere, the more long-wave radiation reflected back to earth, and the higher the mean temperature of the planet goes (H2Ogas is responsible for from 36 to 70% of the greenhouse effect: http://en.wikipedia.org/wiki/Greenhouse_gas ). The higher the mean temp, the more melting of the ice packs, the higher the level of the oceans, and the more H2Ogas in the atmo. Positive feedback. Also, the oceans are a heat sink. The more water in the oceans, the greater the thermal storage capacity of the oceans. I generally don't pay any attention to those who maintain that the modelling algorithyms are deficient or measurements are in error. They don't grasp the concept of modelling, nor of confidence intervals, accuracy, and precision. I used to model (using physical models) displacement of crude oil from rock (sandstone, etc. Permeable) using alkaline flooding with or without polymers. I didn't need to know the atmospheric pressure in order to calculate the pressure drop across the model. I didn't need to know how often the heating elements came on to maintain the =/- 0.5C temp stability. I didn't need to know the composition of the rock (I also used a Lucite model I designed using 150-200 mesh screened and washed sand as the solid matrix). Predictions could be made without knowing a LOT of experimental conditions. The confirmation of the predictions using the models was the basis for the computer models. That's only one example. We use modelling because it works. The scientists doing the modelling thought of all this shit a LONG time before Rush or O'Lielly or the other scientifically illiterate dumbfuck rightards. It's usually as pointless explaining GCC to them as it is explaining Evolution.
