Four weeks of climate data:Southern Temperate Region #6

The last region is the temperate section of the South Atlantic.

Just so we are clear, temperate islands are NOT tropical islands, and ten degrees of latitude can make a huge difference. It's cool in Tristan de Cunha and COLD in the South Georgia Islands.

A few years were taken out because only one island or the other was reporting. Taken together the Summer temperature jumped over a degree, which is definitely to be noticed.

On the other hand, the Fall median barely moved, though the record highs and lows did show a big jump.

In the Winter data, both the record high and median more of less flatline.

Spring shows increase in the high and median.

Confidence of the region warming:90.8%
Confidence of increasing rate: 79.2%
Change in median temperature from the 1955-1975 interval to the 1999-2010 interval: 0.46° C

We are not 95% confident the trend is warming here and the median composite rose less than a half degree Celsius in 56 years, which is not a serious cause for alarm.

This is the last region to look at in our Four Weeks of Climate Data, so now we will go into recap mode, looking at what regions are showing serious increases of more than a degree C from 1955-2010 and which ones are not warming as fast, starting with our six slices of the Arctic.
