Major Update: This is a quote from Reto RuedyÂ Jim Hansen on August 10, 2007 regarding the US GISS temp data:
He [McCyntire] concentrates on the US time series which (US covering less than 2% of the world)Â is so noisy and has such a large margin of error that no conclusions can be drawn from it at this point.
Excuse me? The US has the most complete coverage and the most accurate sensors out there, and it is too noisy to make any historic conclusions from? This is headline news! Go to page 36 in the pdf linked below to find this little confession.
Clarification: the admission that the US data is ‘noisy’ does come originally from Hansen, and is expanded by Reto. So it is a Hansen confession.Â - end update
Steve McCyntire noted that Judicial Watch had acquired and released a series of emails regarding the adjustments NASA GISS made to the US temp record due to some missed corrections. In their snobbish and arrogant effort to belittle those asking questions about what was the warmest year on record, they inadvertently admitted that the current warm period is not significantly greater than the warm spots seen in the US in the 1930′s and 1950′s.
The admission is found in a tidbit in one email, where GISS admits their standard deviation is 0.47Â°C (which begs the question about any warming trend measured at 0.8Â°C). Â What this means is the years, 1934, 1998, 1921, 2006, 1931, 1999, 1953, 1990, 1938 and 1939 (the top 10 ‘warmest’ years in America) are all statistically the same ‘warmth’. They all fall within the GISSN claimed standard deviation.
Which begs the question about this chart:
It would seem to me that if these years are all statistically equivalent, then today’s temps are no different than those seen in the 1930′s. Â More fun with numbers.
