The Significance of Canadian Wildfires on Climate and Public Health

Smoke from numerous wildfires in eastern Canada has created a thick haze in the Northeast and Midwest regions of the United States. As the fires continue, there is a possibility that more smoke could reach these areas in the coming week.

Dartmouth professors Justin Mankin and Laura Paulin have shared their insights on the implications of the Canadian wildfires for climate change and public health, as well as how we should prepare for the future.

In the past, large-scale wildfires were more commonly associated with western North America, rather than the wet and green Atlantic Seaboard. However, these recent fires have demonstrated that global warming can increase the risk of wildfires regardless of the region. Professor Mankin, an expert in geography and co-lead of the NOAA Drought Task Force, explains that the fire conditions in Canada developed quickly due to below-average precipitation and above-average spring temperatures, likely influenced by global warming. While a month of below-average precipitation alone would not typically result in widespread fires, the combination of elevated temperatures and drought conditions accelerated the fire risk in just a few weeks.

According to Professor Mankin, intense wildfire seasons occur when it is hot and dry, and the recent events in Canada are no exception. The combination of a high-pressure system and warm spring temperatures resulted in reduced precipitation, drying out the forests. All it took was an ignition source and favorable winds for the fires to spread. While the exact influence of global warming on these fires is uncertain, a warming climate increases the likelihood of hot and dry conditions, which favor wildfire outbreaks.

Unlike the wildfires in the western United States, the sensitivity of wildfire to temperature and precipitation changes in eastern North America is not well known. Factors such as fire suppression practices, ecosystem health, and climate change impact the region differently. Professor Mankin emphasizes the need to recognize that even areas traditionally considered to have wet climates, like eastern Canada, can be susceptible to wildfires due to temperature changes. This event serves as a reminder that no place is immune to the widespread impacts of wildfires, including the smoke and public health burden they represent.

Professor Paulin, an expert in medicine and epidemiology, highlights the health risks associated with exposure to wildfire smoke. The recent wildfires have led to diminished air quality in the affected regions, with New York City experiencing the lowest air quality of any major city. She explains that as climate change leads to more frequent wildfires and poor air quality due to heat, humidity, and ozone, it is essential for people to understand the health effects and learn how to protect themselves. Public health tools like the air quality index can help individuals make informed decisions during such events.

It is crucial for individuals to be aware of their limitations and the seriousness of breathing in smoke. Professor Paulin advises against outdoor exercise during wildfire events, as heavy breathing increases exposure to particulate matter. Indoor activities should also be considered carefully, as burning candles or wood can further contribute to poor air quality. She suggests that healthcare professionals receive proper training on climate change and air pollution to better counsel patients and recognize symptoms of exposure.

In conclusion, the Canadian wildfires have highlighted the need for preparedness and awareness in the face of climate change-induced events. Understanding the risks and taking necessary precautions can help mitigate the impact on public health. As we navigate a changing climate, it is essential to stay informed and adapt to the challenges it presents.
