World War II “corrections” live on in dubious Hadley Centre SST data from deep in the Southern Ocean

World War II “corrections” live on in dubious Hadley Centre SST data from deep in the Southern Ocean

I had been admiring Steve McIntyre’s demolition of the Steig et al 2009 claims (much promoted in the Australian media) that Antarctic was “warming after all”. I think this is the first article on Climate Audit, then several others followed into February. Try not to miss, When Harry Met Gill

It turns out there were errors in Automatic Weather Station (AWS) data, surprise, surprise.
Also enjoying reading of the discomfort from UnRealClimate as their paradigm unraveled on the world stage. While digging around in Antarctic data to check on the claims of Steig et al 2009 to have found a West Antarctic “Hot Spot”, I thought I would check first what UAH satellite lower troposphere trends showed for the region from 180 west to 60 west and south of 60 south, also what GISS land data showed for that region. Using data from the KNMI Climate Explorer.

Both GISS and UAH MSU lower troposphere agree there is no trend 1979-2008 for that region which includes the Steig et al “hot spot”, see maps at Climate Audit. You can try the sector from 70 south too, still great agreement between GISS and UAH that there is no warming.
Clearly Steig et al should have checked their data against other datasets and they might have been lead to discover the errors in their AWS data and could have saved taxpayers the trouble of paying to publish their dubious claims.

Then I was curious what SST data showed for the 120 degree sector from 180 west to 60 west and south of 60 south, which includes the Steig et al “hot spot”; I came across these odd aberrations in the latest HadISST1 data.
