AUSTRALIAN DATA FIDDLED BY CRU

Professor Wibjorn Karlen’s statement to CRU about Australia:

“Another example is North Australia. NASA [GHCN] only presents 3 stations covering the period 1897-1992. What kind of data is the IPCC North Australia diagram [below] based on?"





"If any trend it is a slight cooling. However, if a shorter period (1949-2005) is used, the temperature [trend] has increased substantially. The Australians have many stations and have published more detailed maps of changes and trends.”

One of the things that was revealed in the released CRU emails is that the CRU uses the Global Historical Climate Network (GHCN) dataset for its raw data. It uses three stations in North Australia as Wibjorn said, and nine stations in all of Australia, that cover the period 1900-2000. Three is not a lot of stations, but that’s all of the century-long Australian records we have in the IPCC North Australia region.


Here is the average of the RAW GHCN unadjusted data for those SAME three Northern stations at Darwin, Alice Springs and Yamba, from AIS. NO UPWARD TREND




Here are the RAW data for the 30 stations with century-long records in Northern Australia. NO UPWARD TREND





Here are the RAW data for absolutely ALL the 222 stations in Northern Australia, irrespective of length of the record. NO UPWARD TREND.





SO WHY IS CRU CHERRY-PICKING THE DATA AND THEN TORTURING IT ?

I SUPPOSE IT'S COS THEY WANT TO DEMONSTRATE THEIR THESIS OF 'ANTHROPOGENIC GLOBAL WARMING'




So what happened with the CRU/IPCC numbers?





"Before getting homogenized, temperatures (blue) in Darwin were falling at 0.7 Celsius per century … but after the homogenization (red), they were warming at 1.2 Celsius per century. And the adjustment (black) that they made was over two degrees per century … when those guys “adjust”, they don’t mess around. And the adjustment is an odd shape, with the adjustment first going stepwise, then climbing roughly to stop at 2.4C."
