Hansen and the “Destruction of Creation”

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% […]

Does Hansen’s Error “Matter”?

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 […]

“Lights Out Upstairs”

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. […]

A New Leaderboard at the U.S. Open

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, […]

Quantifying the Hansen Y2K Error

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 […]

Hansen’s Y2K Error

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 […]
