If people have something to do with climate change, the region containing China should show warming to a significant confidence level. But how far does the human element reach and in what direction?
The region is completely on land, but there are grid points that aren't well enough covered to be part of our average.
Winter's data is all over the place. The warmest Winter in the past 56 years is in this century, but the median and the coldest winter indicators both dropped from the 1988-1999 interval. The warmest record and the coldest record rose over a degree from the first time period to the last, but the median rose about a half degree, not an impressive climb in a half century.
Spring is one of those sets of data that showed "global cooling" in the 1970s, but since then we see a warming trend. This time, the median jumps about a degree in a half century, but the highs and lows did not climb a complete degree in the same era.
Cooling then warming, every measurement showing less than a degree increase in a half century.
Not particularly impressive data.
The record Fall temperature this century is way below several high temperatures last century and all three measurement systems dropped from the 1988-1999 era to the 1999-2010 time period.
Simply enough, this is yet another region that does not show a significant warming from 1955 to 2010. The Northern Temperate Zone goes through four of the most populated slices and only two show significant warming trends.
The story isn't over, but the idea that humans are a significant cause of widespread warming trends across the planet takes a significant hit with this data.
Tomorrow, we look at regions 5 and 6, the first two of four regions that are dominated by the North Pacific.
