NASA/GISS has been adjusting temperatures since 2000

Thanks to emails revealed via FOIA requests, we now know that NASA’s Goddard Institute for Space Studies has been adjusting satellite temperature data since 2000.

But adjusting temperatures which way? Down? Sideways? In three-dimensional space?

I’m kidding. Of course they adjusted them up.

In another email, he reveals that NASA had inflated its temperature data since 2000 on a questionable basis. “[NASA's] assumption that the adjustments made the older data consistent with future data… may not have been correct,” he says. “Indeed, in 490 of the 1057 stations the USHCN data were up to 1C colder than the corresponding GHCN data, in 77 stations the data were the same, and in the remaining 490 stations the USHCN data were warmer than the GHCN data.”

And there’s this:

The emails reveal that GISS, like CRU, has done a poor job of preserving and managing its data. Although there is no evidence that GISS has destroyed its data, as CRU did in the late 1980s, Dr. Reto Ruedy of GISS admits in an email that “[The United States Historical Climate Network] data are not routinely kept up-to-date.”

Who cares about preserving your data when science is just a figleaf to further your agenda?
