In this paper, this framework is applied to the Global
Historical Climatology Network land temperature dataset to present a new global land
temperature reconstruction from 1800 to present with error uncertainties that include many key
effects. In so doing, we find that the global land mean temperature has increased by 0.911 ±
0.042 C since the 1950s (95% confidence for statistical and spatial uncertainties). This change is
consistent with global land-surface warming results previously reported, but with reduced
uncertainty.
“The planet has been warming,” says a new study of temperature records, conducted by Berkeley professor Richard Muller.
I wonder what he’ll be telling us next: that night follows day? That water is wet? That great white sharks have nasty pointy teeth? That sheep go “baaaa”?
There was no peer review done of this person's work and it was released through a press release, need more be said about this "study"?????

In the other temp series the temp increase is over 50% due to the adjustments alledgedly due to problems in observations, equipment, moves… In Dr. Muller’s series he apprently used similar adjustments with NO studies to verify their applicability to all the stations they are applied to. This is an unknown that makes his claim to better certainty a joke. There was also no attempt to survey ANY of the stations to determine if they have any long term biases or are even calibrated correctly… Again, GIGO.
(for our French (the France that's located in Europe) readers GIGO = Garbage In Garbage Out)
The Berkeley Earth Surface Temperature project today released some information about their research. Judith Curry, one of the co-authors, reports this here. The BBC has a story here, and the Economist reports it here.

All we have here is confirmation of warming, the first step. This has been by far the strongest part of this chain and has been for a long time. It’s already well established — as I’ve said before, we know there’s been warming since the Little Ice Age — that’s how we know it was the Little Ice Age.
