Four weeks of climate data:Southern Temperate Region #4

Now we look at the temperate part of the South Pacific Ocean between New Zealand and South America.

Most of the famous South Pacific Islands are in the tropics. The best known of these islands are Easter Island, rightmost at (-105° long, -30° lat) and Pitcairn, where the Bounty mutineers settled, the second rightmost.

The low temperatures for Summer bounce around a lot, but the median shows steady increase.

Fall numbers show an increase at nearly every step.

Again, the low temperatures are bouncing around but the median grows steadily.

The cold Spring late last decade keeps this graph from showing steady increase everywhere.

Confidence of the region warming: 99.%
Confidence of decreasing rate: 65.8%
Change in median temperature from the 1955-1975 interval to the 1999-2010 interval: 0.45° C

We get a similar story to many of our regions. Yes, it's warming. No, we can't say if the rate is increasing or decreasing with any confidence and the amount of warming is in the range of a half degree Celsius in 56 years.


Tomorrow, our last two regions, Temperate South America and the temperate south Atlantic.
