Michigan residents have experienced hazy skies and poor air quality in recent summers, primarily due to Canadian wildfires. Experts warn that this is becoming the ‘new normal.’ The smoke, containing fine particles and pollutants, poses health risks, especially for vulnerable populations. This article delves into the factors contributing to these smoky conditions, the impact of climate change, and offers guidance on how Michiganders can cope with this emerging reality.
The increasing frequency of these events underscores the need to understand the underlying causes and prepare for potential future impacts. By examining expert opinions and available data, this article aims to provide a comprehensive overview of the situation and offer practical advice for navigating smoky summers in Michigan.
Canadian Wildfires: A Major Contributor
The primary source of Michigan’s smoky skies is the surge in Canadian wildfires. A near-record fire season in Canada has resulted in vast amounts of smoke drifting southward. While some politicians have pointed fingers at Canada’s forest management, experts emphasize that the issue is more complex.
Laura Bourgeau-Chavez, a forest fire expert at Michigan Technological University, notes that Canadian officials cannot control the weather. Climate change is a significant factor, creating conditions conducive to megafires. These fires are becoming increasingly difficult to manage, regardless of forest management practices.

Climate Change: The Underlying Driver
Climate change is identified as the main driver behind the increasing frequency and intensity of wildfires. Rising temperatures, altered precipitation patterns, and prolonged droughts create ideal conditions for fires to ignite and spread rapidly. The US, as a major emitter of greenhouse gases, contributes significantly to this global problem.
Richard Rood, a professor emeritus of climate and space sciences at the University of Michigan, explains that warmer temperatures lead to earlier snowmelt, which deprives forests of moisture during dry summer months. This, coupled with warmer nights, makes it harder to contain fires.
‘Having a smoke season is becoming more routine,’ says Richard Rood, a professor emeritus of climate and space sciences at the University of Michigan.
Forest Management Practices: A Complicating Factor
Misguided forest management practices also play a role in exacerbating the wildfire situation. Decades of fire suppression have led to a buildup of dry brush and deadwood, essentially turning forests into tinderboxes. This makes fires more intense and harder to control.
Chad Papa, director of the Michigan State University Forest Carbon and Climate Program, points out that North America’s forests evolved with fire. However, suppression efforts have disrupted this natural cycle, leading to an accumulation of flammable material.
‘There is no short-term or easy fix,’ says Chad Papa, regarding solutions to forest management issues.
Impact on Michigan’s Air Quality
The smoke from these wildfires significantly impacts Michigan’s air quality. The fine particles and pollutants in the smoke can cause respiratory problems, cardiovascular issues, and other health concerns. Children, pregnant women, the elderly, and individuals with pre-existing conditions are particularly vulnerable.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) closely monitors air quality and issues alerts when necessary. Residents are advised to take precautions, such as staying indoors, using air purifiers, and wearing masks when outdoors.
Alec Kownacki, a meteorologist with EGLE, notes that wind patterns play a crucial role in determining when smoke plumes affect Michigan. While southerly winds can provide temporary relief, the wildfire season in Canada typically lasts until October, leaving ample time for smoke to return.
Strategies for Coping with Smoky Days
Given the likelihood of recurring smoky summers, Michiganders need to develop strategies for coping with poor air quality. These include:
- Closing windows and doors to minimize indoor air pollution.
- Using indoor air purifiers to filter out fine particles.
- Running air conditioners with filtration systems.
- Avoiding strenuous activities outdoors during smoky periods.
- Wearing N95 masks when outdoor exposure is unavoidable.
Richard Rood advises residents to develop a comprehensive strategy for coping with smoky days, recognizing that this may be the new normal.
The Need for Long-Term Solutions
Addressing the root causes of worsening wildfires requires long-term solutions. This includes reducing greenhouse gas emissions, implementing sustainable forest management practices, and increasing investments in wildfire prevention and suppression.
Radical changes to energy policies in the US and abroad are essential to curb climate change and mitigate the risk of future megafires. Additionally, reintroducing fire back onto the landscape through controlled burns can help reduce the buildup of flammable material.
Conclusion: Adapting to a Smoky Future
Smoky summers are becoming a recurring reality for Michigan residents, driven by Canadian wildfires and exacerbated by climate change and forest management practices. While short-term solutions can help individuals cope with poor air quality, long-term strategies are needed to address the underlying causes.
By understanding the factors contributing to these smoky conditions and taking proactive measures, Michiganders can protect their health and adapt to this emerging ‘new normal.’
