premature deaths a year in the four cities, making it much deadlier than heat alone. Ozone, nitric and sulphur oxides, key components in the smog and haze that often hangs over the cities in the summer months, are the most deadly pollutants.

The results point to an increasingly deadly trend. "Across the study area, heat related mortality could more than double by the 2050s and triple by the 2080s," they reported. But people tend to grow accustomed to heat, and the scientists said acclimatization could blunt the impact of the rising temperatures. When they factored acclimatization into the equation, heat related mortality still climbed 70 90% by the 2050s and by 120 140% by 2080 across the study area, with slightly higher values projected for Montreal and Ottawa.
