Regrading claim of manipulation by CRU of Siberian temperature data
“I have long suspected that this selective fiddle took place but have not assembled all the evidence.
“We know, and have published, that between 1975 and 2000 the number of weather stations was reduced from nearly 7,000 to only 3,000 with many of them in the former Soviet Union.
“The effect of this would be to produce an artificial temperature trend which we don’t see in the satellite data. So the warming of the past 30 years is likely to be an illusion.”
