NOAA has as expected announced that June 2009 for the globe was the
second warmest June in 130 years, falling just short of 2005. NASA GISS which starts with NCDC GHCN and then adds their own special touches had this June the
second warmest on record just behind 1998.
In SHARP contrast, NASA UAH MSU satellite assessment had June virtually normal (+0.001C or 15th coldest in 31 years) and RSS (+0.075C or 14th coldest in 31 years). This is becoming a habit.
NOAA proclaimed May 2009 to be the 4th warmest for the globe in 130 years of record keeping. Meanwhile NASA UAH MSU satellite assessment showed it was the 15th coldest May in the 31 years of its record. This divergence is not new and has been growing. Just a year ago, NOAA proclaimed June 2008 to be the 8th warmest for the globe in 129 years of record keeping. Meanwhile NASA satellites showed it was the 9th coldest June in the 30 years of its record.
We have noted in the last year that NOAA has often become the warmest of the 5 major data sets in their monthly global anomalies. They were second place until they removed the USHCN UHI adjustment in 2007 and introduced a new ocean data set recently.
NOAA and the other ground based data centers would have more credibility if one of the changes resulting in a reduction of the warming trend and not an exaggeration which has been the case each and every time.
