This summer in Minnesota has had frequent periods of thick, smoky air brought on by Canadian wildfires. It has propelled conversations about the health impacts and climate change links, according to Minnesota News Connection.
Last week saw many parts of Minnesota under air quality alerts that limited outdoor activity due to the smoke.
Kate Knuth — founder of Democracy and Climate LLC — said longer periods of warm and dry weather are pulling moisture out of the air, spurring more wildfires across Canada. She said the recent smoke events aren't likely to be isolated.
"We need to be learning to live in a changing climate," Knuth said. "And dealing with wildfire smoke is unfortunately one of those things we need to learn to navigate here in Minnesota."
Knuth is the managing and research director for the 100% Campaign, which has pushed Minnesota policymakers to recently adopt a 100% clean energy standard.
But she added residents can do their part to spur positive change by embracing climate-friendly energy and transportation sources.
Health experts are urging people to monitor conditions and to avoid strenuous outdoor activities when the air quality is bad.
Dr. Laalitha Surapaneni, assistant professor at the University of Minnesota Medical School, said research is just starting to emerge about the health impacts of wildfires.
She noted smoke from these fires contains particulate matter also found in fossil fuel emissions.
"And so, we know that particulate matter can cause cardiovascular mortality," Surapaneni said. "It can cause development of childhood asthma, and it's also been linked to lung cancer."
Surapaneni, who is also a member of the Health Professionals for a Healthy Climate initiative, said the biggest concern is for vulnerable populations, such as those with underlying heart and lung conditions.
"The three top things would be, you know, limit time outdoors, if you do have to go outside, wear a well-fitting N95 mask. And then, try to create a clean-air room inside your house."Dr. Laalitha Surapaneni
But she said even healthier people can experience things like headaches and burning eyes. However, there are ways to protect yourself.
"The three top things would be, you know, limit time outdoors," Surapaneni said. "If you do have to go outside, wear a well-fitting N95 mask. And then, try to create a clean-air room inside your house."
That type of room blocks all outside air. For those who lack access to these protections, she said communities can establish clean-air spaces with good ventilation, such as a public library.
During periods when wildfires are prevalent, the public is urged to check local air quality reports or monitor the news media in case unhealthy smoke drifts into their region. Download the AQI index app AirNow from theU.S. Air Quality here.
