Ontario: The planet saw its warmest day on record earlier this month, and climate models predict that the severity of heat waves and poor air quality will worsen and continue to have serious consequences.
Researchers from the University of Waterloo and Toronto Metropolitan University enhanced and expanded a data collection strategy to analyse the impact on health.
They discovered that even moderate temperature increases, for example, night-time temperatures starting at 18.4 degrees Celsius, can lead to increased hospital visits and death for older adults and those with cardiorespiratory conditions.
The new method will help municipalities make a strong case for choosing which mitigation and adaptation measures to pursue to effectively respond to climate change.
The options could include planting more trees for shade, investing in our emergency warning programs, or planning to have more staff available to run ambulances, support hospitals and long-term care homes.

“Heat waves cause more deaths in Canada than any other climate hazard,” said Dr Mohamed Dardir, a postdoctoral researcher in the School of Environment, Enterprise and Development at Waterloo.
“We are getting better at being proactive and planning for climate emergencies, but we still aren’t responding to temperatures in the same way we respond to big weather events, such as floods and fires.”
The study analyzed the spring and summer in Mississauga and Brampton, Ontario. By integrating data on air quality and heat, the researchers achieved the most detailed picture of the short-term health risks impacting the vulnerable population on a municipal level.
The findings confirm there was an increase in the total deaths and hospital visits in these areas with the highest impact happening on the day of the heat and poor air quality and extending two days after these events.
In the future, the team plans to expand their analysis to include more environmental hazards, such as storms and floods, and factors including ambulatory calls across municipalities in Ontario and other provinces.

The researchers say that this work will help civil society and policymakers grasp the magnitude of these climate events and equip decision-makers to justify investments in climate resiliency.
“Much of the financial burden to mitigate the impacts of hot temperatures is left to municipalities, but the health system savings are largely experienced by provinces,” said Dr. Jeffrey Wilson, professor in the School of Environment, Enterprise and Development in Waterloo’s Faculty of Environment.
“Being able to detail the cost savings and benefits for society to implement these measures will help the two levels of government understand why working together to address heat events is important.” (ANI)
