WHEN Tim Flannery was sacked last week as Australia’s Climate Commissioner he claimed that this last year has been the hottest on record. I don’t believe him because the raw data doesn’t support that claim, only the metadata for Australia, which has been adjusted, shows recent warming. Willis Eschenbach explains how they ‘fix the data’ in an article published back in 2009 titled ‘The Smoking Gun at Darwin Zero’ [1].
Mr Eschenbach showed how, from the hundreds of available weather recording stations in Australia, the IPCC used only three stations to cover the period 1897 to 1992 [1]. Not only were the IPCC selective in the stations used, they ‘homogenized’ the raw data from these stations before using it. Homogenization had the effect of causing a 0.7C per century falling temperature trend to show a 1.2C per century increase with the adjustments made involving a change of over 2C per century.
Mr Eschenbach made the comment that, “when those guys ‘adust’, 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.”
All five global temperature estimates show no increase, at least since 2002, fig. 1 [click on the image for a larger and clearer view]. There has been no increase in global air temperature since 1998, which was affected by the oceanographic El Nino event of that time [2].
