An inconvenient truth about an inconvenient truth

[...] Even James Hansen from NASA, the father of global warming theory, and Richard Lindzen, the world-renowned climatologist from MIT, agree that if nothing is done to restrict greenhouse emissions, the global temperature will only increase about one degree Celsius in the next fifty to one hundred years (The Science of Global Warming, Internet). The best computer model from the National Center for Atmospheric Research shows that even if followed by every nation, the Kyoto treaty would lower the global temperature eighteen hundredths of a degree Celsius over the next fifty years (Taylor 314). [...]

[...] Perhaps the most puzzling thing is that the temperature in the stratosphere appears to be cooling (Monti 298). Temperature records are often cited to show warming trends, but it is important to see where they are from and in what context they are taken out of. Many kinds of data can be misleading when taken out of context. Temperature measurements are not the only incorrectly cited proof of global warming. Often, news reports show large pieces of glaciers melting, or polar bears stranded on ever shrinking pieces of ice. [...]

[...] Nearly all of the predictions made about global warming are done on a computer. These computers attempt to model the earth's complex interaction of different factors to try and determine future conditions. Modeling future climate changes is impossible, however because of the complexity of the climate system (Cited in Crichton 327). Scientists simply do not know all of the factors that determine climate and small changes in the system can have large effects in the final outcome. The temperature measures often cited are also not as reliable as many believe. [...]
