Four weeks of climate data: Southern Tropics Region #3

 This is the last of the Southern Tropics in the Eastern Hemisphere, covering Indonesia, New Guinea, the tropical part of Australia and a lot of the islands east of Australia. New Zealand is far to the south of this region, entirely contained in the Southern Temperate region.

There are reliable weather stations all over this region.

This is yet another region whose coldest and warmest average temperatures are not that far apart. The median shows a very steady increase, neither speeding up or slowing down.

The Fall median looks a lot like the Summer, showing steady increase but not growing faster or slower.

The Winter temperatures bounce around a little bit more, but the last two time intervals are definitely warmer than the first two.

Spring temperatures are definitely on the rise in all metrics, but that rise appears to be slowing down.

Confidence of the region warming: 99.9%
Confidence of increasing rate: 50%, neither speeding up or slowing down.

Change in median temperature from the 1955-1975 interval to the 1999-2010 interval: 0.55° C

Yet again, the trend is definitely warming, but the rise averages out to very close to 0.01° C a year, which is not catastrophically fast.

Later today, another slice of the tropical southern ocean with a lot more water than land.
