Northern Hemisphere Winter Doom By Latitude Band

Winter temperatures in the Northern Hemisphere are dropping as much as 2.5C / decade over the last 7 years.

Yesterday my post was a look at the northern hemisphere by month over the last 7 years.

Today I am looking at the same time frame, but I am using the gridded HADCRUT4 data for Dec/Jan/Feb only. You will have to click on the image to get the full effect.

There are 7 latitude bands with yellow highlighting. The trend in those is from -.44C/decade to -2.49C/decade. And note the green 0 line. 0 is the 1961-1990 average, Anywhere the graph or trend crosses the green line it is colder than the 1961-1990 average. It was pretty cold in the 60s and 70s.

I wish I didn’t live in the 50th parallel.
