The Australian BoM has made much media fanfare with its claims that 2005 has been Australia’s hottest year. Coolwire 17 points out that the Climate Research Unit (CRU) at the University of Norwich, long quoted by the IPCC and the Universit of Alabama at Huntsville group compiling satellite data for the lower troposphere, both produce anomaly maps showing 1998 was warmer for Australia.
The NASA GISS group do agree with the BoM that 1998 was warmer than 2005 but they quote data from 1 Nov 2004 to 30 Nov 2005, not calendar 2005. However we count that as a point for the BoM.
UAH does not measure surface temps, and thus is an apple to the oranges of GISS and CRU. What does the other data set (NCDC, the new one) say? Could Oz "win" best of three?
