Pattern recognition of temperature trends for Antarctica from linear and nonlinear regression analyses

[摘要] There is an overwhelming evidence for the South Pole of stable temperatures, with all the latest news reporting on presently cooling temperatures and increasing ice coverage. The thermometer records for the stations of Byrd, Bellingshausen, Novolazarevskaya, Mirny, Vostok, Progress, Russkaya,Molodeznaya and Leningradskaya are analysed together with the satellite measurements of surface air temperatures and sea ice extent. The thermometer records are often scattered data biased by heat release and heat storage processes nearby the thermometer location, but globally they do not support any particularwarming trend over the full length of the records that in the best cases is 55 years long. The satellite measurements of temperatures and sea ice extent conversely clearly support a cooling trend over the 35 years of the record. The Antarctic region is undoubtely presently cooling, as the ice surrounding Antarctica is expanding, and the coolest place on Earth was recently discovered in Antarctica.
