Willis Eschenbach Does Yeoman’s Work on Climate Data

I do not know the gentleman whose name appears in the title–but I would like to. He starts out with an intro with which I think we can all agree:

People say “Yes, they destroyed emails, and hid from Freedom of information Acts, and messed with proxies, and fought to keep other scientists’ papers out of the journals … but that doesn’t affect the data, the data is still good.” Which sounds reasonable.

Then he goes to work on the data to see how good it really is. The post is long and complicated at times (as one might find when viewing a person performing trending analysis of numerical data points). However, his conclusion: that the raw data at Darwin, Australia has been severely adjusted for no supportable reason to appear as though temperatures are increasing. In his own words:

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.

Go read it all and let it sink in a bit.

Then, for desert, head on over to The Virtuous Republic for more of the same. I’m thinking that I might need to spend a bit of time looking through the data for some local weather stations tonight myself. This is where An Army of Davids that Glenn Reynolds talks about can make a difference.
