Northern Hemisphere this time. Snow Water Equivalent.
March 2000: According to Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia,within a few years winter snowfall will become “a very rare and exciting event”.
“Children just aren’t going to know what snow is,” he said.
Snow seems to be ignoring David Viner.
I usually post Northern Hemisphere. But here is North America Snow Water Equivalent.

Northern Hemisphere Snow Water Equivalent above normal all year.
“When scientists looked at Antarctic snowfall over the past 200 years they found a “significant” increase, up to 10%.
In the decade 2001-2010, some 272 billion tons more snow fell on Antarctica per year compared with the decade 1801-1810.
This extra amount of snow is equivalent to twice the water volume of the Dead Sea, on a per year basis.”
These graphs are NH only.
Its a pity Rutgers graphing script can’t spell Hemisphere.
But …
Fall up 1,500,000 sq km
Winter up 900,000 sq km
Spring down 3,000,000

Northern Hemisphere Snow Water Equivalent above normal all year … except for the day all the snow melted (and then came back).
This a followup to this post: British Columbia Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid)
The following map shows which stations were missing (or not missing) daily Tmax data in the monthly summary for April 2015.
Blue had 0-3 days missing. Red more than 3. What saddens me is that 19 out of the 43 “red” stations were also “Normals” – which means they were reference stations.

The following maps show which grid cells (apprximately) had data in a few key years.
This is the Alberta followup the BC post. You can read the explnations.
In the terms of Tmax the coldest period in Alberta (using 5 year means) was 1972-1976.
The warmest period was 1940 – 1944. In fact it was 2C warmer in 1940-1944 than 2011 – 2015. (The 1930s were just slightly cooler than the early 40s)
You may ask why the green line of grid counts goes up and down so much. It appears there are many more stations reporting in May/Jun/Jul/Aug/Sep than in the winter.
