I have mapped the January 2014 anomalies in the Environment Canada monthly summaries that have “normals”. The anomalies are calculated from selected stations based on the 1971-2000 average.
The size if the dot represents the size of the anomaly. The 5C black dot in the top left hand corner represents 5C difference from “normal”. Red dots are warmer than normal. Blue are cooler. And Green are 0.
Not much sign of the Polar Vortex in BC and Alberta for January. A big change from December.
The AGW cult likes to talk about “extreme weather” as if that is a new thing and all was nice and calm in the past before that evil CO2 came along. What a load of bull.
Inspired by my own post about 1930 temperatures in Canada and Steven Goddards post about “extreme weather” in Montana in 1936, I thought I should take a quick look at 1936.
Imagine you are in the middle of the worst 10 year heatwave ever in North America — the dust bowl — and along comes February 1936. The data in the graph below are monthly averages based on the 1971-2000 normals Canada uses.
The black dot in the top left hand corner is about 5C of difference above or below the normal for that month.
Of the 184 stations, 3 were above 0. 81 were more than -10C colder than normal. Animated gif of whole year at bottom. Click for bigger.

Yesterday I mapped the anomalies for 2013 using the Environment Canada monthly summaries that have “normals”. The anomalies are calculated from selected stations based on the 1971-2000 average.
Today I thought … why not 1930. I picked 1930 because I know the dustbowl occurred in the 1930s. So I assumed it would be warm at times. Remember, this is the anomaly from the 1971-2000 averages. It started out cold, but December was 3.21C warmer!
An example of the effect of the dustbowl. “In 1928, the net Farming income was $363 million; by 1933, it dropped to $11 million; and by 1937, two-thirds of the farm population of Saskatchewan was destitute.”

April was cold. December ended up very cold across the country.

Using the stations in Canada with Environment Canada calculated anomalies, here is the month of May visualized using the mean temperature for each station for each day.

The black circle in the top left corner represents a 5 Celsius anomaly from the 1971-2000 average.
Blue are below normal. Red above.
I thought I would map just the stations that were exactly average just for fun:
Doesn’t this sound ominous! “ice” retreat” has “sharply accelerated since 2004”.
“Across the Canadian Arctic Archipelago, widespread ice retreat during the 20th century has sharply accelerated since 2004.
In Sverdrup Pass, central Ellesmere Island, rapid glacier retreat is exposing intact plant communities
whose radiocarbon dates demonstrate entombment during the Little Ice Age (1550–1850 AD).”
Except …. doesn’t that mean the plant communities were thriving before 1550?
And that means the Medieval Warm Period existed. And that current ice melt is just a return to normal?

Nunavut (northern Canada) was the coldest Province/Territory in May.
Environment Canada calculates “Normals” for a subset of stations. Those are the anomalies from the 1971-2000 average.
The following barplots are of the daily anomalies (TMax and TMin) for each Nunavut station (that have Normals) averaged together.
The coldest part of the month was 6 to 7C below the 1971-2000 average. So much for the overheating Arctic.
Environment Canada calculates “Normals” for a subset of stations. Those are the anomalies from the 1971-2000 average.
I just started using the daily data this month. (The monthly summaries have proven to be unreliable)
So … using stations with Normals, here are the 100 stations with the coldest TMIN anomalies.

According to the Environment Canada “Normals” (the stations EC calculates anomalies for) , Canada was colder than the 1971-2000 average in April 2013.
The mean of all the “Normals” was -1.83C colder than 1971-2000 average.
If you look in the top left corder of the anomaly map and note the black circle represents 5C anomalies. Blue is colder than normal. Red is warmer.
The middle of the country was really, really cold. What little warmth there was, was concentrated in a handful of arctic stations.
And many of the stations had values too small to really show up on the map.
The anomaly map for April 2013 follows. Click to make it bigger.
Where do I get the data? From Environment Canada monthly summaries.
The URL for April 2013 BC data is here. You can replace BC with nothing (PROV=) or SASK or MAN etc.
I use the data with a D column value because EC calculates the anomalies for me. And because they are supposed to be better/long stations.
