If these climate change predictions come true, massive heat waves will be the norm. The map on the left shows the current situation: Most of the Prairies is shaded blue (meaning 10 or fewer days when the temperature tops 30 C) with only Palliser’s Triangle in the light-green or yellow zones (20 to 25 days of +30 C). On the right is the prediction for the years after 2050 if there isn’t a reduction in greenhouse gases — with 30 to 45 days of scorching hot weather in a typical summer. Source: Alberta Farmer.
