Here is an interesting splice of Moberg and satellite data. Blue is Moberg, grey is Moberg error bars, red is instrumental, all downloaded from the Nature SI; purple is satellite. At right is the post-1850 blow-up. You can see that the post-1980 satellite temperatures are high but not off the charts relative to Moberg’s reconstruction.
To even contemplate use of Moberg, the Hockey Team has to rely entirely on the splice of CRU records, rather than satellite records. Warwick Hughes and others have expressed concerns about how CRU have handled urban heat island effects and other issues. There are some very interesting issues in SST temperatures on how adjustments have been done for change-over from measuring temperatures in buckets to engine inlets, which I’ll post about some time.
A couple of years ago (before I had any notoriety), I asked Phil Jones for the data used in the UHI study published in Nature and relied upon by IPCC. Jones told me that it was on one of dozens of diskettes in his office and he couldn’t find it. I didn’t pursue the matter at the time. You may recall Phil Jones’ response to Warwick Hughes’ request for the underlying station data:
We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it.
Phil Jones’ construction of temperature data sets has been financed by the U.S. Department of Energy. Whether the CRU data sets are right or wrong, they need to be audited. I don’t see why the Hockey Team should be exempt from audit standards.
