It’s ‘the hottest year on record’, as long as you don’t take its temperature
Sunday, December 19, 2010
We have lately heard much of the claim that 2010 will turn out to have been“the hottest year on record”. No one has done more to promote this beliefthan Dr James Hansen, head of Nasa’s Goddard Institute for Space Studies(GISS), responsible for one of the four main official global temperaturerecords.
As reported by the US blogs Real Science and Watts Up With That, in a postheaded “GISS temperatures out of line with the rest of the world”, the GISSrecord has in recent months been diverging wildly from the others. Whilethree have shown global temperatures dropping sharply, by as much as 0.3C,the GISS figures (based, despite the link to Nasa, on surface temperatures)have shot up by 0.2C.
In a second post (“Hansen’s ‘Hottest Year Ever’ is primarily based onfabricated data”), Real Science demonstrates that the parts of the worldwhich GISS shows to be heating up the most are so short of weather stationsthat only 25 per cent of the figures are based on actual temperaturereadings.
The rest are simply conjectured by GISS. This is not the firsttime Dr Hansen’s temperature record has come under expert fire. Three yearsago, GISS was forced to revise many of its figures when it was shown thatwholesale “adjustments” had been made, revising older temperatures downwardsand post-2000 figures upwards.
