Commentary on Delaware Online is a further demonstration of how notions there is a "debate" about whether global warming is real are just plain wrong.

An op-ed article in The Wall Street Journal a month ago claimed that a published study affirming the existence of a scientific consensus on the reality of global warming had been refuted. This charge was repeated again in a hearing of the House Committee on Energy and Commerce. I am the author of that study, which appeared two years ago in the journal Science, and I’m here to tell you that the consensus stands. The argument put forward in the Wall Street Journal was based on an Internet posting; it has not appeared in a peer-reviewed journal — the normal way to challenge an academic finding. (The Wall Street Journal didn’t even get my name right!) My study demonstrated that there is no significant disagreement within the scientific community that the Earth is warming and that human activities are the principal cause. Papers that continue to rehash arguments that have already been addressed and questions that have already been answered will, of course, be rejected by scientific journals, and this explains my findings. Not a single paper in a large sample of peer-reviewed scientific journals between 1993 and 2003 refuted the consensus position, summarized by the National Academy of Sciences, that "most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations." …

To be sure, there are a handful of scientists, including Massachusetts Institute of Technology professor Richard Lindzen, the author of the Wall Street Journal editorial, who disagree with the rest of the scientific community. To a historian of science like me, this is not surprising. In any scientific community, there are always some individuals who simply refuse to accept new ideas and evidence. This is especially true when the new evidence strikes at their core beliefs and values. … Climate-change deniers can imagine all the hypotheses they like, but it will not change the facts nor "the general induction from the phenomena."
