Global warming and the test of Science

Science proceeds by developing hypotheses (theories) and testing them against experiment. Successful theories agree with experiment. Unsuccessful ones are discarded by scientists. It is thus important to track how well global warming predictions match experimental data. So let us consider last year's big thaw prediction:

The source of the story was Dr. Mark Serreze of the National Snow and Ice Data Center (NSIDC) who was predicting a 50/50 chance that the north pole would be ice-free by Summer 2008. The melt didn't happen, not even close, and arctic ice is now in its normal range.

Dr. Serreze is one of Al Gore's key environmental advisers and was recently promoted to director of NSIDC.
