how come climate science has a different definition of science?
here is how GISS manufactures a warming trend in Antarctica
The close match between GISS and me after 1955 is encouraging in that it shows that theres at least one corner of the Earth where GISS hasnt seriously mutilated the raw data. But GISS bumps Antarctic warming up from little or none since 1955 to two full degrees since 1900 by extending the Antarctic record back to 1904. Heres where GISS gets the pre-1955 temperatures from:
The 1945-55 temperatures come entirely from stations on and around the Antarctic Peninsula that show much more warming than the mainland stations over the period of common record after 1955, and the 1904-44 temperatures come from a single station Base Orcadas in the South Orkneys northeast of the Antarctic Peninsula.
Projecting temperatures from the Antarctic Peninsula over the entire the entire 64-90S latitude zone, which covers an area of 25 million square kilometers, is bad enough, and projecting temperatures from a single record like Base Orcadas over a zone this large is even worse. But it gets worse yet. The map below shows where Base Orcadas is. At 60 degrees 44 minutes south latitude IT ISNT EVEN IN the 64-90S latitude zone. Its in the next GISS latitude zone up the 44-64S zone.
Its hard to see how data manipulation in the service of global warming could get much more creative than that.
