The concept of “Excess Winter Deaths” is straightforward. Winter kills.
You could save 3 people a day from dying in the winter by raising temps 5C.
If the temperature went up 5C in Ontario, it would kill 4 people a day in summer.
If the temperature went up 5C in Ontario, it would save 7 people a day in winter.
In warm seasons, each 5°C increase in daily mean temperature was associated with a 2.5% increase in nonaccidental deaths (95% confidence interval [CI] = 1.3% to 3.8%) on the day of exposure (lag 0). In cold seasons, each 5°C decrease in daily temperature was associated with a 3.0% (95% CI 1.8% to 4.2%) increase in nonaccidental deaths, which persisted over 7 days (lag 0-6). The cold-related effects (lag 0-6) were stronger for cardiovascular-related deaths (any cardiovascular death: 4.1%, 95% CI 2.3% to 5.9%; ischemic heart disease: 5.8%, 95% CI…
