The Canadian Climate Survey is tracking historical and average temperatures in cities and towns across the country, as part of an effort to put something of a local face on global climate change.
Temperature Extremes: Over the period since the 1880s, only 2 of Calgary’s 10 hottest years have occurred in the two decades since 1990. In addition, 1 of the city’s coldest years has happened in the same timespan — 1996, when the average temperature plummeted to 1.9 ˚C.
Long-Term Consequences: Since the 1980s the city’s temperatures have plateaued at 4.7 ˚C.
