When climatologists such as John Coleman debunk AGW, the believers contest that he is not the right kind of scientist to dispute the “science”. He is after all “just a weatherman”.
Al Gore is certainly no scientist and has less credentials than John Coleman on the subject. Yet he is considered an authority on the subject by the believers. The “science” is debatable; the “certainty” is disturbing. Gore has consistently refused to debate the issue. “The debate is over” is certainly not the language of science. Nor is treating skeptics like heretics.
Climate Gate has shown that even “scientists” can be biased by the influence of money. For every “scientist” that supports AGW there is a “scientist” debunking it.
The greater fallacies in the AGW argument are fallacies of logic, not science. The idea of certainty in such a hugely uncertain and massive realm just defies common sense.
Science welcomes skepticism, religions generally do not.
