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 1930s, 6 of Aroostook’s 10 hottest years have occurred in the two decades since 1990. In contrast, none of its 10 coldest years happened in the same timespan. The coldest year in that interval, 1997, was the town’s 14th-coldest year on record.
Long-Term Consequences: Since the 1980s, the town has been warming at the rate of 0.35 ˚C per decade. If the rate of warming does not change, this would mean a temperature rise of 3.5 ˚C over the coming century.
