> Global warming is not a theory, it is a fact, enough evidence that is beyond reproach of any kind is left that we can safely conclude that this is apparently really so. Relativity is a theory, even though it has been experimentally verified. Newtonian mechanics and the luminiferous aether are also theories. Gravity, global warming (on any given timescale), the freezing point of water, and the presence of little green men on Mars are facts. But in order to conclude that global warming is a true fact, you need to specify it better. "The earth was warmer at the end of 2008 than at the end of 2005" is false[1]; "the earth was warmer at the end of 2009 than at the end of 1999" is true; "the earth was warmer at the end of 2008 than at the end of 1988" depends on whether you're talking about monthly (true) or trailing-12-months (false) measurements. If you pick your date range right, you can get any truth-value you want. [1] http://vortex.nsstc.uah.edu/public/msu/t2lt/tltglhmam_5.2 http://vortex.nsstc.uah.edu/public/msu/t2lt/tltglhmam_5.2
