Four weeks of climate data:
Northern Temperate Region #7


The seventh slice of the Northern Temperate Zone is the first in the Western Hemisphere moving from west to east. It includes a very small part of Russia and most of the populated part of Alaska, a term I used advisedly.


Alaska is definitely not Antarctica. There are people there and we get weather readings from all over the state.


The Winter data shows the record warm season was in this century, but there is no consistent trend of warming or cooling when looking at all three yardsticks.


The Spring data again looks like it bounces around randomly with the only warming trend being no extra cold Springs since the 1980s.


The warmest Summer records show some increase, but the median and coolest data do not.


The Fall temperatures show some warming trends, but overall the data does not present a convincing trend of warming, with 18 steps upward, 16 downward and two remaining the same. The rate of change is not getting faster either.  This is another region where we cannot say with 95% confidence that we are seeing a warming trend.

Later today, region #8, which includes the rest of Alaska and much of northwest Canada, them extends southward down the Pacific coast to the central part of California.
