The price of climate change is real. This crisis has already taken lives in extreme heat waves, and is increasing risks to Canadians from flooding, and from respiratory illnesses like asthma. Bold, urgent action is not only needed – the science is clear that it will make a real difference. Many of these health impacts can be prevented by scaling up efforts to adapt to climate change in an intersectional manner—both in Canadian society at large and in health systems. Strong adaptation measures can prevent potential health impacts and make health systems and facilities more resilient to climate change.
