Nevertheless, over the past several decades an increasing number of scientists have shed the restraints imposed by the scientific method and begun to proclaim the truth of man-made global warming. This is a hypothesis that remains untested, makes no predictions that can be tested in the near future, and cannot offer a numerical explanation for the limited evidence to which it clings. No equations have been shown to explain the relationship between fossil-fuel emission and global temperature. The only predictions that have been made are apocalyptic, so the hypothesis has to be accepted before it can be tested.

The only evidence that can be said to support this so-called scientific consensus is the supposed correlation of historical global temperatures with historical carbon-dioxide content in the atmosphere. Even if we do not question the accuracy of our estimates of global temperatures into previous centuries, and even if we ignore the falling global temperatures over the past decade as fossil-fuel emissions have continued to increase, an honest scientist would still have to admit that the hypothesis of man-made global warming hardly rises to the level of "an assertion of what has been or would be the result of carrying out a specified observational procedure." Global warming may or may not be "the greatest scam in history," as it was recently called by John Coleman, a prominent meteorologist and the founder of the Weather Channel. Certainly, however, under the scientific method it does not rise to the level of an "item of physical knowledge."

Nevertheless, the acceptance of man-made global warming as scientific fact has become so prevalent that the secretary-general of the United Nations, Ban Ki-Moon, recently declared: "The debate is over. It's time to discuss solutions." Leaving aside the question of the secretary-general's qualifications, that is certainly one of the most antiscientific statements ever made. The first question that this raises is why have so many scientists chosen to ignore this glaring failure of the global warming hypothesis to meet the standards of their own profession? The second question is what, if anything, can be done about it?
