Computerized models of the Earth's climate are at the heart of the debate over how policymakers should respond to climate change. Global climate models (GCMs)--also called general circulation models--attempt to predict future climate conditions by starting with a set of assumptions about how the climate works and making guesses about what a future world might look like in terms of such factors as population, energy use, and technological development.
Numerous analysts have pointed out, however, that many of the assumptions used in modeling the climate are of dubious merit, with biases that tend to project catastrophic warming. As a consequence, these analysts argue, climate models have many limitations that make them unsuitable as the basis for developing public policy.
