As Rupert goes through its umpteenth day of overcast skies with intermittent rain and cold temperatures, our friends in Eastern Canada are living through a major heatwave.
But it seems the east has been seeing higher temperatures than the west for many years now. A few weeks ago, Statistics Canada released a report called Human Activity and the Environment. One of the tables in that report, compiled from data by Environment Canada, showed 2010 was the warmest year on record nationally since 1948. In the eastern regions, such as Atlantic Canada and the Northeastern Forest, 2010 was also the warmest on record; when things get to the Prairies, however, 2010 was the 23rd-warmest year on record since 1948.
The graph below shows how 2010 temperatures by Canadian region differed from the average temperature from 1948-2010. For example, Atlantic Canada’s average temperature in 2010 was 2.1 degrees warmer than the long-term average (from 1948-2010). One column to the right, the Great Lakes region was 1.9 degrees warmer than the average.
The data show that temperatures in Eastern Canada are warmer than the averages in Western Canada. But the hot spot in Canada turns out to be the north, which saw much warmer temperatures than either the East or West.
