Global Warming Crisis

Larry Bell makes the case that global warming is causing a crisis: its effect on science.The latest IPCC report deals with the fact that the climate models (computer programs) that it has relied upon for predictions of the next 50-200 years have been proven spectacularly wrong. The IPCC response:
2001: “Most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”.
2007: “Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.”
2013 (leaked draft): “It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010.”
That's right, the first half-decade of test results show no evidence to support the hypothesis.
      conclusion: we are "very likely" right.
The second half decade of results are an undeniable refutation.
      conclusion: we are "extremely likely" to be right.

This, my friends, is a dramatic new development in the scientific method. For those of us who liked the old scientific method, it is a crisis.
