Every day, some charming dead fish floats to the surface...



Anybody who is not following Climategate must be brain-dead. It's a feast of revelations. A daily banquet. Here's a taste from a good one by Willis Eschenbach, from Watts Up With That?, The Smoking Gun At Darwin Zero:

...Figure 8 Darwin Zero Homogeneity Adjustments. Black line shows amount and timing of adjustments.

Yikes again, double yikes! What on earth justifies that adjustment? How can they do that? We have five different records covering Darwin from 1941 on. They all agree almost exactly. Why adjust them at all? They've just added a huge artificial totally imaginary trend to the last half of the raw data! Now it looks like the IPCC diagram in Figure 1, all right ... but a six degree per century trend? And in the shape of a regular stepped pyramid climbing to heaven? What's up with that?

Those, dear friends, are the clumsy fingerprints of someone messing with the data Egyptian style ... they are indisputable evidence that the "homogenized" data has been changed to fit someone's preconceptions about whether the earth is warming.

One thing is clear from this. People who say that "Climategate was only about scientists behaving badly, but the data is OK" are wrong. At least one part of the data is bad, too. The Smoking Gun for that statement is at Darwin Zero.

So once again, I'm left with an unsolved mystery. How and why did the GHCN "adjust" Darwin's historical temperature to show radical warming? Why did they adjust it stepwise? Do Phil Jones and the CRU folks use the "adjusted" or the raw GHCN dataset? My guess is the adjusted one since it shows warming, but of course we still don't know … because despite all of this, the CRU still hasn't released the list of data that they actually use, just the station list.

Another odd fact, the GHCN adjusted Station 1 to match Darwin Zero's strange adjustment, but they left Station 2 (which covers much of the same period, and as per Fig. 5 is in excellent agreement with Station Zero and Station 1) totally untouched. They only homogenized two of the three. Then they averaged them....
