Update: Another coastal station has been added: Novolazarevsk, so it’s 11 stations.
Over the past few years, climate alarmists have increasingly been resorting to weather-ambulance chasing, which has necessitated the trotting of the globe in the search of weather anomalies to behold as proof of man-made climate change.
But one place they have been avoiding like the plague is Antarctica as a number of studies have been showing the opposite of what what predicted earlier has been happening down at the South Pole, except for volcanic activity beneath parts of the Antarctic ice shelf.
Analysis of Antarctic stations show cooling
Today we look at 10 Antarctic station under operation in Antarctica, scattered along the Antarctic coastline and operated by various countries. These are not impacted by volcanic activity:With the 2018 data in, now is a good time to look at the long-term temperature trends of these stations. We do know that Antarctic sea ice extent has seen an impressive upward trend over the past 40 years, and so tells us cooling may be at play:
Antarctic sea ice has gained steadily over the past 40 years. Chart: Comiso et al, 2017
What follows are annual mean temperature charts of each of the 10 Antarctic stations unimpacted by volcanic activity.
Butler Island and Neumayer
Both show a clear downward trend:
Halley as well shows a downward station since 1956:
Syowa and Casey
Data from the Japan operated Syowa station and the Australia Casey stations both show no trend since 1961. Here we see no signs of any warming:
So far not a single station remote of volcanic activity has shown any warming.
The Davis station data go back 35 years and show a flat trend (very slight cooling in fact). No warming has been detected there since the great global warming scare began in the 1980s. So far 6 of the 6 stations plotted show no warming over the last several decades.
This Antarctic station shows a definite cooling trend over the past 30 years:
The Mirnyl station has been recording temperature data since 1967, i.e. more than half a century. It too is statistically flat, even showing a very slight cooling trend:
Dumont D’Urvi and Mawson
Both D’Urvi and Mawson Antarctic stations have recorded data going back to the 1950s. As the following chart tells us, there’s been no warming at these two long term stations as well.
