Occasional Thoughts on Climate Change

Hey Charlie,

 I looked and looked at this and still can’t see how this doesn’t have errors. What am I missing? Am I having a brain fart? Is this the # of days within March 1-22, 2026, with highs of 80+?

 I came back and looked again to see if my brain had been missing something. I still don’t see how a good portion of the #s on the map aren’t off. Is this mislabeled?

 

I believe that's the ranking, not the number of days.

Thanks, Don. Now it makes sense if the words “ranking of” are added before # of days of 80+.

I should have been clearer. The chart I posted is the ranking of the number of days over 80, with #1 being the highest. Below is the number of 80+ days on which the ranking is based.

In addition to Fairbanks, cities such as Anchorage and Yellowknife, NW Territories as well as the area in between and surrounding have a chance to have their all time record coldest Marches. That’s ~2,000 miles long and ~400 miles wide area or ~800K square miles, which is ~18% of the combined square miles in Canada and Alaska or ~25% of the size of the lower 48!

 Does anyone have a link to monthly records for Canadian cities and more specifically Yellowknife? Anyone have a link to maps showing historic temperature anomalies by month for Canada like we have for the US?

 Yellowknife in March of 2026:

Mean temp March 1-23: -26C

Normal for entire month: -16C

Here's Yellowknife's coldest March:

That translates into a monthly mean temperature of -17.6°F.

Thanks, Don! This tells me that Yellowknife won’t be as cold this month as it was in March of 1964.
 
 Unlike 2026, that month was post El Nino, opposite of 2026. That month was also quite cold further N, N of 80N (<-30C):

 

Compare that to the current March so far, which is ~-20C or >10C warmer!!

 It looks like that finally Phoenix didn’t 100. It was “only” 99 today.

The most extreme March heatwave on record in the United States is now concluding. Additional monthly records were set today. Below is a selection of March records that matched or beat April records during the unprecedented heatwave.
