Sen. John McCain and Global Warming

Advertisement

Unless some other candidate enters the race I will be voting for you in November. However, that is only because neither of the likely Democratic candidates has the experience to be the nation's Chief Executive Officer. Your acceptance of the nonsense about purported "global warming", which Meteorologist John Coleman calls "the greatest scam in history", indicates a level of gullibility that is undesirable in presidents. I can understand how American leaders would believe that Saddam Hussein still had significant amounts of Weapons of Mass Destruction. Hussein had used such weapons in the past and there was no evidence he had destroyed them. U.N. inspectors discovered unloaded nerve gas shells shortly before the U.S. invaded Iraq. However, there is no evidence for "global warming". There is no evidence of any significant temperature change other than the normal rise and fall of temperatures over time. The earth has warm years and cool years, warm decades and cool decades. The process that is supposed to produce global warming is physically impossible. Those who claim the existence of global warming admit that temperatures only changed by 1 F or 0.17% during the entire 20th Century. A one degree variation is insignificant considering that daily temperatures fluctuate by 20 - 30 F and by over 100 F from winter to summer in temperate areas during the year. The passage of a strong cold front can drop temperatures by 30 F in a matter of hours.A one degree change over a century could easily be explained by differences in equipment or changes in the locations where the equipment is located. Today's equipment is of questionable reliability. Many sites have characteristics that artificially produce higher temperatures. Temperature varies by more than one degree in different parts of my yard. Temperatures went up and down during the 20th Century and have declined since 1998. The concept of a global average temperature itself is of questionable value.Jean Baptiste Fourier first suggested that infrared radiation (IR) from the surface heated the atmosphere, but Fourier also believed that star light could heat the earth. He believed that gas molecules converted the radiation into heat. Niels Bohr demonstrated in his Nobel Prize winning research that absorption of specific wavelengths of light by gas molecules changed the energy state of their electrons rather than causing them to become hotter.Land and water heat the air by conduction rather than radiation. 70% of the earth's surface is water which is a very poor radiator anyway. Supporters of global warming have failed to provide any evidence that the low energy radiation produced by earth's surface can heat anything.Those who believe in global warming claim that it is caused by carbon dioxide (CO2) trapping a small range of IR. However, physicist R.W. Wood, who invented IR photography, demonstrated in 1909 that the process of trapping IR didn't cause greenhouses to stay warm. Instead they stayed warm because they trapped heated air which doesn't readily lose heat energy by converting it into radiation. His experiment used solid barriers to trap IR. CO2 is less than 400 parts per million in the atmosphere and is hardly capable of trapping IR the way the solid barriers Wood used could.Ferenc Miskolczi resigned in protest from NASA after it suppressed a study indicating that the equations used to show CO2 would cause substantial global warming contained a serious flaw that rendered the equations invalid. His corrected equations show no warming.Dr. Gerhard Gerlich and Ralf D. Tscheuschner in their essay "Falsification of the Atmospheric Greenhouse Effects Within the Framework of Physics" argue that the process global warming believers talk about would be a perpetual motion machine that physicists claim would violate the laws of physics.
