Landmark EIKE study of global temperature trends 1906-2005 using 2249 GISS stations concludes 0.17 UHI and a non-urban baseline warming only 0.41 degreesApril 8th, 2012 by Warwick Hughes
This global study at the European Institute for Climate and Energy (EIKE) – How Natural is the Recent Centennial Warming? – is the first that jumps to mind in over two decades by a group sceptical of AGW – that applies statistical analysis to thousands of temperature station data and concludes there is a standout UHI signal.
Andrew Bolt has an article on this – “Climate study: er, what man-made warming?”
I just hope this is the start of a determined research effort that might in the years ahead blunt the harm done to science by over two decades of the UHI infested various CRUTem versions.
