New Realities. Las Vegas had 128 deg Fahrenheit in July 2007 and, if the jet stream pattern continues to move to the East, Chicago and New York will learn the new meaning for a "Heat Wave". After that, everyone will believe in Global Warming, even if the Heat Wave is unrelated to Global Warming. However, there is another possibility, the Presidential Primary of February 5th, 2008, will include California and the candidates are already promoting the "most aggressive" stand on Global Warming. For example, some propose a 50% Carbon reduction by 2050 and others demand an 80% Carbon reduction. None of them specify what will replace the energy source and what will that do to the economy. At this time, it is posturing but by 2011, the issue will be when will sales of gasoline end and what fuel will take its place. Some are already arguing for use of Nuclear Power to produce Hydrogen and support this as being the "cheapest" provided, note, provided "you exclude the construction costs", a typical "political bookeeping ploy" that candidates must find useful since, they seem to think, most voters either don't read, don't care or what?
