Maximum, Mean, Whatever

The Antarctic is warming!

Well, actually, the warmest of 17 stations in the Antarctic was used to create the false impression that the entire Antarctic is warming. From the Air Vent:

There are like 1500 six figure people in the Antarctic and the primary GHCN global dataset has only one single series since 1993. The heroic global warming scientists at Rothera Point have been slaving away, reporting data for all of the Antarctic. That’s 16 years without anyone else bothering to take a temperature reading in the Antarctic for the GHCN or anyone from the GHCN making a phone call to any of the Antarctic towns for the data.

Oops, not so quick. There was data in the other series. In the GHCN’s unique value added process, (invented and widely sanctioned in the superior science of climatology) denialist data has been eliminated from the Raw data as we can see below.


So as we can see, of all the stations available in the antarctic, GHCN has chosen to use a single station on the Antarctic Peninsula to represent an entire continent of the earth for the past 17 years (red circle). But it’s not just any station, it’s a special one. Rothera Point has the single highest trend of any of the adjusted station data.
