Cold Summer in Nunavut


A previous post explored the claim that “Nunavut is melting” and is reproduced below.  On September 6 Jane George posted at the Northwest Passage blog declaring the opposite:  As ice and snow return, summer’s over in Nunavut  “It was a cold summer.”  Excerpts below in italics with my bolds.

This map from the Canadian Ice Service shows sea ice conditions in the western part of High Arctic islands on Sept. 8. The dark blue shows a low concentration (less than 10 per cent) of ice, while white shows a high concentration (100 per cent). At this time of the year, the Arctic ice cover is the highest it has been since 2014, the National Snow and Ice Data Center said Sept. 5.

Snow has now fallen across Nunavut’s more northerly communities, from Kugluktuk to Qikiqtarjuaq, after a summer that also brought cool temperatures and heavy ice conditions to some parts of Nunavut.

“if you’re trying to get somewhere, and ice is in the way, it’s been a very bad year,” said Gilles Langis, a senior ice forecaster with the Canadian Ice Service.

It remains unclear if ice played a role in the grounding of the Ioffe Akademik on Aug. 24. The cruise ship was not sailing where it was supposed to be due to ice, according to an account by the journalist and author Ed Struzik, who was on board.

And, earlier this week, operators of the cruise vessel Hanseatic turned around and headed back east through the Northwest Passage, having decided that ice conditions were too bad to continue on to western Nunavut.

The Canadian Coast Guard also recently rescued two sailors from a smaller vessel that had run into bad ice conditions in the Bellot Strait.

Summing up the summer ice conditions in 2018, Langis said that in many areas it was “very challenging”—in parts of Hudson Bay, Hudson Strait, Baffin Bay and at various choke points in the Northwest Passage where the ice pushed in.

Ice conditions are not likely to improve.  And as for the weather, it’s not likely not to be warming up either.

“It was a cold summer,” said Brian Proctor from Environment Canada. As well, northern Canada saw above normal precipitation in many communities because of a low pressure front stalled over the North.

Iqaluit experienced its 13th coldest and 14th wettest year in 73 years, he said.

In Qikiqtarjuaq, where snow also came early, it was the seventh coldest summer in 22 years.

Previous post:  Nunavut is Melting!  Or not.

From Yale Climate Connections we heard last week about Nunavut melting and a theatrical production to spread news and concerns about this dangerous development.

“I come from a place of rugged mountains, imperial glaciers and tender-covered permafrost. But Nunavut, our land, is only as rich as it is cold, and today most of it is melting.”That’s Chantal Bilodeau, reading a passage from “Sila,” a play about the effects of climate change in the Arctic.

The characters in her play include polar bears, an Inuit goddess, scientists, and coast guard officers – all working together to save their land.

No doubt her personal experience and feelings for her Nunavut are sincere and profound. (Originally I thought it was her homeland, but in fact she is a New York playwright and translator, born in Montreal.) And there will be a large audience receptive to her concerns about global warming. (Bilodeau has writen six plays about the Arctic and founded the international network Artists And Climate Change.) But I wonder if scientific measurements support her belief that Nunavut is melting.

After all, we have learned from medical research that individual life experiences (anecdotes) may not be true more generally. That is why drugs are tested on population samples with double-blind studies: neither the patient nor the doctor knows who gets the medicine and who gets the placebo.

So I went looking for weather station records to see what is the warming trend in that region. As curiosity does so often, it led me on a journey of discovery, learning some new things, and relearning old ones with fresh implications.

Where are temperatures measured in Nunavut?

It is by far the Northernmost territory of Canada, just off the coast of Northern Greenland.

According to Environment Canada, weather is reported at 29 places in Nunavut. So I went to look at the record at Iqaluit, the capital of the territory. You get monthly normals for the period 1981 to 2010. Historical data (daily averages) can be accessed only 1 individual month/year at a time, the menu stops at 2004. Even then, some months are filled with “M” for missing. Historical data from which trends can be analyzed is hard to come by.

Disappearing Weather Records

It turns out that Nunavut also suffered from the great purging of weather station records that was noticed by skeptics years ago.

I was aware of this because of a recent study looking at trends at stations around the Arctic circle. Arctic Warming Unalarming.  That study included graphs that showed the dramatic removal of station records in the North.  Though the depletion was not limited to the far North, many Canadian and Russian records disappeared from the global database.

The red curve is the moving 5-year average while the blue curve shows the number of stations reporting in each year. 118 stations contributed to the study. W. A. van Wijngaarden, Theoretical & Applied Climatology (2015)

Eureka, Nunavut, Canada “Last Station above latitude 65N”

Eureka got considerable attention in 2010 due to its surviving the dying out of weather stations. The phrase in quotes above reflects an observation that GISS uses Eureka data to infill across the whole Arctic Circle. That single station record is hugely magnified in its global impact in that temperature reconstruction product. Somewhat like the influence of a single tree in Yamal upon the infamous hockey stick graph.

The first High Arctic Weather Station in history, Eureka was established in April 1947 at 80-degrees north latitude in the vicinity of two rivers, which provided fresh water to the six-man United States Army Air Force team that parachuted in. They erected Jamesway huts to shelter themselves and their equipment until August, when an icebreaker reached Eureka – as it has every year since – and brought permanent buildings and supplies. For decades after that, small, all-male crews would hunker down for entire winters, going a little stir-crazy from the isolation. WUWT 2010

GHCN Records for Nunavut

It turns out that in addition to Eureka, GCHN has data for Alert and Clyde (River), but the latter two histories end in 2004 and 2010, respectively. The adjusted files have a few differences in details, but little change from the unadjusted files. The chart below shows the temperatures measured at Eureka, Nunavut, Canada 79° 98’ N, 85° 93’ W.  The other two stations tell the same story as Eureka, though temperatures at Clyde are warmer in absolute terms due to its more Southerly location.

Eureka temps4

The chart shows Annual, July and January averages along with the lifetime averages of Eureka station from 1948 through 2015.  There is slight variability, and a few years higher than average, but nothing alarming or even enough for people to sense any change.  Note also that annual averages are well below freezing, because only 3 months are above 0° C.  I suppose that someone could play with anomalies and generate a chart that looked scary, but the numbers in the record do not support fears of global warming and melting in Nunavut.


Once again we see media announcements that confuse subjective beliefs with empirical observations of objective reality.  And unfortunately, those observations are less and less available to counter the herd instincts of fearing the future and blaming someone.

    9th paragraph “As for the weather, it’s not likely not to be warming up either.” ??

      Thanks Kelvin, (named after the Lord who invented the temperature scale?) Fixed.

    This Canadian Climate Trend Site has not been updated since August 2017. I asked why.
    When I finally got an answer from one of the Scientists who assemble the information (but he isn’t responsible for publishing it), I was told that the publication procedure involves translation into both languages, descriptions of figures for people with visual impairments and formatting for multiple devices. He wasn’t sure why that is taking so long, though perhaps resources are going to new platforms, like the Open Data Portal.
    Since last winter was so cold, perhaps the Trend line just isn’t conforming to the message the Liberal Government is trying to sell the public.

    What an excellent article. Do I take it this proves we are in a Mini Iceage?

      Thanks shawnee, too soon to say. One cold summer is not yet proof that this temperature plateau is ending with cooling.

    Here’s a comment I posted on WUWT that might interest you:

    It is interesting to watch the ways the “Death Spiral Believers” keep their beliefs. Here is a study stating “uncertainty” in the models means we may have to wait 100 years before the arctic is ice free…..but it will, it will, it will be ice free….any century now.

    And here is an article by someone who was on the Akademik Ioffe when it grounded in the Arctic a couple of weeks ago. It is interesting because at no point do they mention there is more ice this year than last year. Instead they produce wonders such as, “Sea ice is still a problem, perhaps even more so as it continues to recede” because “the increasingly chaotic nature of the climate system in the Arctic is making it difficult to predict how sea ice is going to behave.”
