The two regions of the Northern Temperate Zone we looked at yesterday, the two that comprise the bulk of Asia in the Temperate Zone, did not show significant warming trends over our time period of 1955-2010, years chosen because they were both strong La Niña years. Today, we look at the last two parts of northeastern Asia, this one including Japan, both Koreas and parts of Russia and China.
The gaps we see are mostly due to regions of the grid being in the Pacific Ocean.
Winters in this region have bounced up and down, the high temperatures most noticeably showing a cooling trend in the 1970s. All our measurement standards have risen from the first interval to the last, the largest rise about a degree Celsius.
The Spring data shows a more consistent increase over time, both the lows and the median increasing steadily from time period to time period.
The Summer temperature metrics agree completely, a cooling trend in the 1975-1988 time interval and steady increase since. The difference in each measurement from the beginning interval to the most recent is only a half degree.
The Fall data shows a drop-off in the record temperature readings but a slight rising in the median and the low.
Largely due to the consistent increasing trend in the Spring and almost consistent trend in the Summer, the number of increases outnumbers the decreases 24-12 and when we put that number into the standard deviation from a 50-50 outcome, we are 95% confident this region shows a warming trend. As with many of our regions, the data showing the warming trend increasing is not conclusive.
Later today, the last Asian slice, mostly the Kamchatka peninsula and a lot of ocean.
