Scientists Find “Surprising” And “Statistically Significant” Cooling Trend Over Entire Continental Antarctica

 Surprising NOT!.  What makes this so important is that this massive climate zone is wonderfully isolated by the Circum Polar Current.  A change is both measurable and important.  Other zones all suffer from a propensity toward measurement drift caused by human activity.  Or a tree growing by a thermometer.  

This is so important because it balso tells us excess heat not coming south must be going somewhere else.  Thus we have a warming era in the Arctic.

The only explanation that i have for this is a possible bulge in the current slowly working its way around the Pole over a thousand year cycle.  One phase of its cycle induces warm water to be forced into the Arctic through the Atlantic.  good luck on proving this.

My point is that the North appears much warmer and the South is proven colder.  This is now likely to go flat for a couple of decades before reversing.

Scientists Find “Surprising” And “Statistically Significant” Cooling Trend Over Entire Continental Antarctica

East Antarctica, which covers two thirds of the South Pole, has cooled a whopping 2.8°C over the past 4 decades; West Antarctica approximately 1.6°C. ..only tiny Antarctic Peninsula saw statistically insignificant warming.

German climate website Die kalte Sonne posted its 64th climate video here and examined a new paper on Antarctica by Zhu et al (2021): “An Assessment of ERA5 Reanalysis for Antarctic Near-Surface Air Temperature

The European Center for Medium-Range Weather Forecasts (ECMWF) released its latest ERA5 reanalysis dataset in 2017 and Zhu and his researchers compared the near-surface temperature data from ERA5 and ERA-Interim with the measured data from 41 weather stations.

They found that the temperature trend from ERA5 is consistent with that from observations. The result: a cooling trend dominates East Antarctica and West Antarctica while a warming trend exists in the Antarctic Peninsula. Note that the regions of east and West Antarctica combined are vastly larger than the tiny Antarctic Peninsula.

Substantial cooling

he results are summarized as follows (cropped from Die kalte Sonne):

The table above shows East Antarctica, which covers two thirds of the continent, saw a cooling of 0.70°C per decade over the past 40 years. In total that particular region has cooled about 2.8°C since 1980.

West Antarctica has cooled at a rate of 0.42°C per decade over the past 40 years.

Die kalte Sonne finds the results “surprising” and “statistically significant”. And though the Antarctic Peninsula has warmed moderately, Die kalte Sonne sees nothing significant happening over this comparatively small region.

This of course should be seen as good news for the global warming alarmists who fear the South Pole might melt.
