CERH researchers participated in a study that was just published in the Lancet Planetary Health. The largest study to date of the potential temperature-related health impacts of climate change has shown that as global temperatures rise, the surge in death rates during hot weather outweighs any decrease in deaths in cold weather, with many regions facing sharp net increases in mortality rates.
The article present estimates of the impact in Finland, based on the Helsinki Metropolitan mortality rates from 1994-2011. The adverse effects of increasing temperature are balanced by reduction in the effects of cold so that the net effect for the worst climate change scenario is close to zero.
