[quote]QUOTE: Originally posted by vsmith FYI this Memorial Day a movie called "The Day After Tommarow" opens with a Global Warming disaster scenario that could actually happen. the premis is that melting fresh water from the north pole, disrupts, then shuts down the Gulf Stream in the Atlantic, causing weather chaos in the US and Europe, triggering another Ice Age. It will probably be full of Hollywood Schmaltz more than facts, but this is a real scientific possibility that has been discussed as a possible fallout from green house warming. Besides the trailer looks really cool... www.thedayaftertomorrow.com [/quote] All I can say to those who use a second-rate Hollywood disaster flick or take a Pentagon "just in case" briefing (which by the way they also have for alien space attacks, giant asteroids, et al) as the basis for instituting radical environmental policy, take stock in two things: Re-read Chicken Little from your grade school days and ask yourselves if such an analogy is applicable today. Secondly, take a look at the historic temperatures of the MIddle Ages, which were much higher than they are today, and ask yourself what man did to cause THAT period of global warming?! If wine grapes were being cultivated in Britian in those days, why can't we grow grapes in Britain now? It's simple: THE AVERAGE TEMPERATURE IS STILL TOO COLD! Why is Greenland called Greenland? Because when it was discovered in the MIddle Ages it was verdant, i.e. GREEN! Now it is one giant ice cap. If man-caused CO2 is the major cause of Global Warming, where did the CO2 in the MIddle Ages come from? How many coal fired power plants were operating at that time? How many SUVs were clogging the byways of the time? Hmmmm. Maybe, just maybe, the warming of that period WASNT caused by man's burning of fossil fuels. If it was something else such as solar activity or slight deviations of the earth's orbit, isn't it logical to ascribe todays warming to those more likely phenomena? So what if 200 or so "scientists" have leapt on to the whole man-caused global warming bandwagon. There are well over 15,000 scientists worldwide who have resisted that urge, due to the inarguable fact that there is no hard physical evidence to support the whole man-caused global warming models. Look at the global warming computer models today and you will find a lot of "assumed" variables being plugged into these models used to support these radical theories. Hardly an excuse for instituting economically disasterous environmental policies. If we refer to our basic laws of physics, we will find that it is more likely that global warming is the cause of increased atmospheric levels of CO2, not the other way around. It's all part of the global carbon cycle, as temperatures increase, plant growth also increases, and these plants will need to take up more CO2 from the atmosphere for sustainability, thus more natural sources of CO2 are triggered. Back to the original subject at hand: If oil prices are projected to stay above $40 a barrel for the long term, look for market forces to allow for new coal powered locomotion in the transportation market, whether it be new steam or the stringing of new cantenary over the nation's rail grid.
