SCIENTISTS at the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center (CPC) appear to have made a blunder with a data adjustment and splice resulting in sea surface temperatures being warmer than they would otherwise be by about 0.175 degrees C over the last two decades.

Roy Spencer, from the University of Alabama, discovered the error just a few days ago which according to meteorologist Anthony Watts, accounts for 24% of the 0.74 deg C global warming claimed for 1905-2005.

The mistake was made about 10 years ago following a request from the World Meteorological Organization for NOAA to standardize the period from which temperature anomalies are calculated.

I have puzzled as to why Australian government advisors claim sea temperatures have been increasing over the last ten years – perhaps they have been referring to sea surface temperatures and focusing on this dud data.
