OK, that was funny. But the 97% number is nonsense, just for the record. Skepticism about AGW catastrophism is rampant among the world's scientists at large (physicists, biologists, etc.), and many climate scientists have been cautiously coming out of the closet and poking sticks at the shaky foundations as well.
This is the original press release about the 97%. By the way, the correct citation is "In analyzing responses by sub-groups, Doran found that climatologists who are active in research showed the strongest consensus on the causes of global warming, with 97 percent agreeing humans play a role. "
Basically the survey found that the experts in the field have 97% consensus. For overall numbers of scientists:
Two questions were key: have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures.
About 90 percent of the scientists agreed with the first question and 82 percent the second.
Ordinary people hear "supercomputer driven model simulation" and they think "oooh, it must be really accurate and able to predict the future".
No I think computer models are really the only thing we have as we don't have a spare planet to experiment upon and god-like powers. But with all models, I don't assume that they are all 100% accurate. But I think they can be constructed to be close enough to determine a reasonable outcome.
Anybody who understands statistics and the banal realities of computation knows the good old GIGO principle. Not to mention the reality that nobody has ever successfully predicted long term climate changes, so throwing a supercomputer at an impossible problem doesn't magically add credibility. *sigh*
No one has ever said that these models are 100% for all future predictions. Like most of science, theories (and models) that best fit observable data are used. And like most of science these are tested. I don't know if this is some sort of delusion or lack of understanding of how science works. Just because a scientist proposes something or releases a paper, it is not automatically accepted without challenge. Data is challenged. Conclusions are challenged.
All science is challenged. Consensus is reached after enough data and evidence is presented that favors the conclusions. Einstein's General Theory of Relativity wasn't accepted because Einstein proposed it. It took a solar eclipse before many physicists began to accept that it might be the best theory. Now by today's standards, the results of solar eclipse experiment would not have been enough.
