Revkin is wobbling

Andrew Revkin in the chief Warmist for the NYT. He is trying to cope with the "discovery" (to Warmists) that atmospheric water vapour is a big influence on the earth's temperature. Excerpt from his article of 29th:

A new study led by Susan Solomon, a federal climate scientist and co-leader of the 2007 science review by the Intergovernmental Panel on Climate Change, is fascinating not only for the revelations, but the underlying lessons, too.

The study, described in an article today in The Times, finds that poorly understood variations in water vapor concentrations in the stratosphere were probably responsible for a substantial wedge of the powerful warming trend in the 1990s and a substantial portion of “the flattening of global average temperatures since 2000″

Here’s the take-home line from the paper: "[S]tratospheric water vapor very likely made substantial contributions to the flattening of the global warming trend since about 2000. Although earlier data are less complete, the observations also suggest that stratospheric water contributed to enhancing the warming observed during 1980–2000."

One lesson, discussed by me for many years, is that short-term variability even on the scale of a decade (in either the hot or not hot direction) is a distraction if one is looking for evidence of human-driven warming or trying to build an argument for or against curbing emissions of greenhouse gases.

Another, of course, is that the science illuminating the extent of the human influence on climate is not “settled” for many specific, and important, points, even though the basic case for rising risks from rising concentrations of greenhouse gases is robust enough to merit a strong response, according to a host of experts (even if you take the intergovernmental panel’s findings with a grain of salt).

Amusing bits: He admits that the science is not "settled"; He admits that people have reason to take the IPCC with a grain of salt; He says that decade-long observations are too short to be used, even though the warming period of the late 20th century that started the whole scare was only about two decades; He then offers an alternative authority to the IPCC as confirming the "threat" of global warming -- an "authority" that was published in 1991! He had to go back to 1991 to prop up his faith!; and that he relies on "authorities" -- rather than any facts -- to prop up his faith is the most pathetic thing of all

  1. Truth will eventually rise to the surface and it doesn't matter how much crap it is buried under.
