Blatantly bogus

Says Anthony Watts:
Now, I want to be clear here. The blatantly bogus GHCN adjustment for this one station does NOT mean that the earth is not warming. It also does NOT mean that the three records (CRU, GISS, and GHCN) are generally wrong either.

This may be an isolated incident, we don't know. But every time the data gets revised and homogenized, the trends keep increasing. Now GISS does their own adjustments. However, as they keep telling us, they get the same answer as GHCN gets … which makes their numbers suspicious as well.

And CRU? Who knows what they use? We're still waiting on that one, no data yet …

What this does show is that there is at least one temperature station where the trend has been artificially increased to give a false warming where the raw data shows cooling. In addition, the average raw data for Northern Australia is quite different from the adjusted, so there must be a number of … mmm … let me say "interesting" adjustments in Northern Australia other than just Darwin.
Says chief UN climate official, Yvo de Boer: four successive reports, peer-reviewed by 2500 scientists, have endorsed the finding that global warming was almost certainly a result of human activities. "I do not believe there is any process anywhere out there that is that systematic, that thorough and that transparent."
