From the told ya so department, comes this recently presented paper at the European Geosciences Union meeting.
Authors Steirou and Koutsoyiannis, after taking homogenization errors into account find global warming over the past century was only about one-half [0.42°C] of that claimed by the IPCC [0.7-0.8°C].
------------------------------------------------
Heres the part I really like: of 67% of the weather stations examined, questionable adjustments were made to raw data that resulted in:
increased positive trends, decreased negative trends, or changed negative trends to positive, whereas the expected proportions would be 1/2 (50%).
And
homogenation practices used until today are mainly statistical, not well justified by experiments, and are rarely supported by metadata. It can be argued that they often lead to false results: natural features of hydroclimatic times series are regarded as errors and are adjusted.

The solution to Glowbull Warming is so easy! If we could lock up Algore and put a ball gag on him that would eliminate the other half. lol
Exactly!
I always ask global warming folks why they think they know, within 1 degree even, the average world temperature in 1850. How many stations were there in the Yukon in 1850? How many in the Amazon? How many reading taken from the middle of the Pacific in 1850? How accurate were the gauges, and who thinks some guy in Alaska in the winter of 1850 was getting readings accurate to 1 degree, let alone 0.01 degree?
They just reply, “Science has proved...”
Exactly. More to the point, the whole idea of "average world temperature" is useless. What's useful, from a human point of view, is measuring the degree to which temperatures diverge from what is optimal for humans, and where.
The assumption here is that (1) there is warming, and (2) warming is always bad. If winters become less harsh in the Yukon and Siberia, and temps stay much the same elsewhere, then that would be considered "global warming", but it would be a GOOD thing.
As George Carlin said in one of his routines, “it’s 82 degrees at the airport. Which is stupid, because no one lives at the airport.”
Tell GISS Hansen that. :)
