==Intro==
Cut from intro:
*into the atmosphere is increasing the temperature of the world by changing the ability of heat to escape the atmosphere.
*Some gases attributed with causing this effect are produced by industrial and power plants, while many others come from natural phenomena. In addition to atmospheric gas content, many other factors control the earth's temperature, which has its own pattern of heating and cooling.
*While many climate scientists have insisted that man-made pollution has caused dangerous warming, some computer models designed to predict long term trends fail to predict recent short-term cooling that the Earth is experiencing. <ref>[http://online.wsj.com/article/SB125686509223717691.html Earth Cools, and Fight Over Warming Heats Up, Wall Street Journal, 2 November 2009]</ref> Because 1998 was the year of El Nino, a natural phenomenon that occurs intermittently and causes the year in which it occurs to be anomalously hot, the relation of that year to longer trends is unclear. As temperatures have been falling since 1998, increasing doubt is being cast on the validity of global warming claims.
We need to distinguish between:
#a period of rising world air temperatures: [[global warming period]]
#a scientific theory about what causes the above: [[global warming theory]]
#what activists mean when they say things like, "Global warming is real"
The first is easy enough. It happens when air temperatures go up.
The second requires explaining all the various major theories explaining this. Liberals hate this, because this gives something for conservatives to compare with reality (see [[independent review]]).
The third is tricky, because you have to unravel the tangled political rhetoric. --[[User:Ed Poor|Ed Poor]] <sup>[[User talk:Ed Poor|Talk]]</sup> 10:50, 4 January 2010 (EST)
