I’ve spent some time (an inordinate amount of time) trying to figure out why GISS uses some GHCN stations and not others. Doing so has required a lot of work on GISS data sets which are nastily organized and with many seemingly ad hoc inclusions, exclusions and sloppinesses. Does any of this matter to world […]
Hansen has followed up his “Lights Out Upstairs” outburst with another outburst dismissing critics as “court jesters” with whom he will have no truck. (Lights Out is now cited on the NASA website.) His new jeremiad re-iterated the position of NASA spokesman Gavin Schmidt that U.S. errors “didn’t matter” because the U.S. was only 2% […]
There’s been quite a bit of publicity about Hansen’s Y2K error and the change in the U.S. leaderboard (by which 1934 is the new warmest U.S. year) in the right-wing blogosphere. In contrast, realclimate has dismissed it a triviality and the climate blogosphere is doing its best to ignore the matter entirely. My own view […]
Hansen has published an online letter entitled A Light On Upstairs? The letter concludes by saying: My apologies if the quick response that I sent to Andy Revkin and several other journalists, including the suggestion that it was a tempest inside somebody’s teapot dome, and that perhaps a light was not on upstairs, was immoderate. […]
There has been some turmoil yesterday on the leaderboard of the U.S. (Temperature) Open and there is a new leader. A little unexpectedly, 1998 had a late bogey and 1934 had a late birdie. (I thought that they were both in the clubhouse since the turmoil seemed to be in the 2000s.) In any event, […]
The GISS homepage formerly said: The NASA GISS Surface Temperature Analysis (GISTEMP) provides a measure of the changing global surface temperature with monthly resolution for the period since 1880, when a reasonably global distribution of meteorological stations was established. Input data for the analysis, collected by many national meteorological services around the world, is the […]
I observed recently that Hansen’s GISS series contains an apparent error in which Hansen switched the source of GISS raw from USHCN adjusted to USHCN raw for all values January 2000 and later. For Detroit Lakes MN, this introduced an error of 0.8 deg C. I’ve collated GISS raw minus USHCN adjusted for all USHCN […]
Eli Rabett and Tamino have both advocated faith-based climate science in respect to USHCN and GISS adjustments. They say that the climate “professionals” know what they’re doing; yes, there are problems with siting and many sites do not meet even minimal compliance standards, but Hansen’s software is able to “fix” the defects in the surface […]
Obviously the big issue in climate is the impact of 2 times CO2. While my own issues tend to be statistical, this site obviously attracts many readers who want to jump straight to discussion of thermodynamics and theories of atmospheric physics. Articles like G and T obviously inflame such tendencies. For some reason, people who […]
