A climate projection model for Ontario predicts an average winter temperature of 2C to 3C as early as 2071, compared to -1C to -2C, what we see today. Summer temperatures may climb from 21C up to 25C or 26C. This trend is likely to occur if we don’t do anything to curb greenhouse gas emissions.
The warming trend can lead to “more smog days and the spread of Lyme disease-carrying ticks, currently kept at bay by cold winters.”
