How does the BEST temperature dataset relate to the datasets of the major climate agencies? Using the BEST monthly anomaly data and the handy Excel correlation function, since 2001 the BEST dataset matches up quite well with the NCDC and CRU data, as the adjacent chart shows.
In essence, when NCDC and CRU temperatures 'zig,' the BEST temps are probably doing the same.
And GISS temps? Not so well. In fact, it's the worst. In contrast, when BEST and the other agency anomalies are 'zigging,' GISS is likely to be 'zagging.' This GISS divergence problem also extends to its performance versus the RSS and UAH satellite datasets, as previously pointed out by skeptics.
Why doesn't the GISS dataset comport with climate reality as documented by other sources and experts? Hmmm...one thinks global warming fame and fortune is not likely to visit those who report modest or little warming.
Since it is now clear that GISS isn't up to the "BEST" standards of science, and there is no good reason for NASA to be in the temperature reporting business in the first place, it's time to fold the GISS tent and save taxpayers some money - outsource the GISS efforts to BEST and be done with it.
Now that BEST has shown GISS to be a wasteful, error-prone (remember the Y2K error) redundancy, maybe it's time to shine a bright light on the idiocy emanating from NOAA's NCDC - their temperature dataset should also be on the hot seat of scrutiny also.
Here is an agency that seemingly has the bizarre mission to change historical temperature anomalies on a monthly basis - literally, every single month. Take the very first month of the NCDC temperature dataset, January 1880. Over the past six months, NCDC has changed the January 1880 anomaly six (6) times.
- Sept. 2011 version of January 1880: -0.0443
- Aug. 2011 version of January 1880: -0.0474
- July 2011 version of January 1880: -0.0468
- June 2011 version of January 1880: -0.0444
- May 2011 version of January 1880: -0.0439
- April 2011 version of January 1880: -0.0428
And it's not just a single month they perform this type of climate science magic on. When NCDC reported the anomalies dataset for the September 2011 reporting period, NCDC had changed every single historical month's anomaly as reported in the August 2011 dataset. They changed all 1,580 months of past temperature reporting, adding in a cumulative warming of +0.0966 in a single stroke! Did we say bizarre yet?
The folks at HadCRU don't practice this blatant monthly form of "global warming" revisionism. The folks at GISS aren't constantly revising historical temperature reporting on a monthly basis. And it's hard to imagine that BEST research team would condone, let alone practice, this style of empirical climate evidence tampering.
If BEST plays their cards right and performs in an upright, objective manner, it's not hard imagining that all of the GISS and NCDC temperature measurement/reporting efforts (not necessarily climate analysis and modeling) being on the chopping block. This would likely result in the U.S. finally having a 'BEST'-of-breed global surface temperature reporting system that could be taken seriously by all sides of the debate.
