Four weeks of climate data:
Antarctica Region #2


Continuing in the Eastern half of Antarctica, as remote from humans as any part of the planet can get.


At least this region gets coverage every year from 1955 to 2010 and has 4 of the 100 grid points checking in.  Still, this is very desolate, even compared to the Arctic Circle.


The Summer clear does not show a warming trend. In fact, the record highs and the median would argue this part of Antarctica is actually cooling.


The median in Fall shows some cooling trend, the highs and lows look relatively static. This kind of bouncing around is what we expect in a time interval that is not changing significantly.


Except that the coldest Winter this century was a lot warmer than cold Winters last century, this data looks like a cooling pattern.


There hasn't been a warm Spring to match the record set in the 1970s, but the last interval this century showed a slight uptick.

Once again, if the null hypothesis is no significant change, there is not enough data to dispute it, either as a warming trend or a cooling trend.

Tomorrow, the last Eastern Hemisphere slice and the first Western Hemisphere part.
