Global warming/debate

About
The debate over global warming is perhaps the single best illustration of why arguments need to be mapped in order to be resolved properly. The sheer volume of resources which have been allocated by industry (especially the fossil fuel industry) towards defeating public acceptance of the various global warming hypotheses has resulted in some arguments that are very elaborate and difficult to answer without a detailed knowledge of not only the basic mechanisms of global warming, but also its history and politics.

Summary
As of 2013, hardly anyone disputes that global warming is in fact occurring; denialism now generally focuses on the following:
 * Humans aren't causing it; the exact mechanism is either unknown or entirely natural.
 * Global warming does not pose a serious problem, and may even be of net benefit. ("We can adapt.")
