Computers are Causing Global Warming

At least, that is, in Nepal.  Willis Eschenbach has an interesting post looking into the claim that Nepal has seen one of the highest warming rates in the world (thus threatening Himalayan glaciers, etc etc).  It turns out there is one (1) GISS station in Nepal, and oddly enough the raw data shows a cooling trend.  Only the intervention of NASA computers heroically transforms a cooling trend into the strong warming trend we all know must really be there because Al Gore says its there and he got a Nobel Prize, didn’t he?

GISS has made a straight-line adjustment of 1.1°C in twenty years, or 5.5°C per century. They have changed a cooling trend to a strong warming trend … I’m sorry, but I see absolutely no scientific basis for that massive adjustment. I don’t care if it was done by a human using their best judgement, done by a computer algorithm utilizing comparison temperatures in India and China, or done by monkeys with typewriters. I don’t buy that adjustment, it is without scientific foundation or credible physical explanation.

At best that is shoddy quality control of an off-the-rails computer algorithm. At worst, the aforesaid monkeys were having a really bad hair day. Either way I say adjusting the Kathmandu temperature record in that manner has no scientific underpinnings at all. We have one stinking record for the whole country of Nepal, which shows cooling. GISS homogenizes the data and claims it wasn’t really cooling at all, it really was warming, and warming at four degrees per century at that

In updates to the post, Eschenbach and his readers track down what is likely driving this bizarre adjustment in the GISS methodology.
