Cartoon by Josh If Michael Crichton had lived to write a follow-up to State of Fear, the plotline might well have gone like this: at a top secret, state of the art laboratory in Switzerland, scientists finally discover the true cause of "global warming". It's the sun, stupid. Sun Causes Climate Change Shock
Verification and validation of numerical models of natural systems is impossible. This is because natural systems are never closed and because model results are always nonunique. Models can be confirmed by the demonstration of agreement between observation and prediction, but confirmation is inherently partial. Complete confirmation is logically precluded by the fallacy of affirming the consequent and by incomplete access to natural phenomena. Models can only be evaluated in relative terms, and their predictive value is always open to question. The primary value of models is heuristic.

Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding. Yet this isn't what happens with climate change denial.
