Statistics needed

Sunday, February 04, 2007
Ex-dem ponted out an excellent article in the National Post concerning global warming. of particular interest are these paragraphs:
"Our committee believes that the assessments that the decade of the 1990s was the hottest decade in a millennium and that 1998 was the hottest year in a millennium cannot be supported," Wegman stated, adding that "The paucity of data in the more remote past makes the hottest-in-a-millennium claims essentially unverifiable." When Wegman corrected Mann's statistical mistakes, the hockey stick disappeared.

Wegman found that Mann made a basic error that "may be easily overlooked by someone not trained in statistical methodology. We note that there is no evidence that Dr. Mann or any of the other authors in paleoclimate studies have had significant interactions with mainstream statisticians." Instead, this small group of climate scientists were working on their own, largely in isolation, and without the academic scrutiny needed to ferret out false assumptions.
I find myself totally unsurprised at Wegman's conclusions. The article is well worth reading in light of the attempts to silence those who are pointing at the emperor's saggy posterior hanging in the sunlight.

I keep hearing from the MSM that human blame for global warming is now beyond debate. But apparently not.. Here is an update on the theory of cosmic-rays, ionization, and cloud fomrmation I mentioned some time ago.

I wonder whatwill happen in a decade or so if none of the really dire predictions come to pass. Will they readjust? Or is this just a passing fancy anyway?

I think there will be more and more doubters like this.

Although the MSM has a strong bias in the global warming direction, if the Dems take the White House, I suspect we'll see some push back on this issue from a media standpoint. Not a lot, but some. The MSM also desires to push back at "power" as conflict is partly what creates ratings.
