Why is the US experiencing severe wildfire smoke now?
Wildfire smoke is reaching the US mainly due to over 550 active fires in Canada, especially in Manitoba. These fires release large amounts of smoke into the atmosphere, which then travels southward, impacting air quality across many US states. The combination of these extensive wildfires and prevailing wind patterns is causing the current surge in smoke levels.

How do heatwaves make air pollution worse?
Heatwaves can worsen air pollution because high temperatures increase the formation of ground-level ozone, a harmful component of smog. Additionally, heat can cause pollutants to become more concentrated and linger longer in the air, making it more dangerous to breathe, especially for vulnerable groups like children, the elderly, and those with respiratory issues.

What can people do to protect themselves from poor air quality?
To stay safe during poor air quality days, people should limit outdoor activities, especially strenuous exercise. Staying indoors with windows closed, using air purifiers if available, and wearing masks designed to filter out smoke particles can help. It’s also important to stay hydrated and monitor local air quality reports regularly.

Will the air quality improve soon?
Air quality may improve as wildfire activity decreases and weather conditions change, but current forecasts suggest smoke and heatwaves could persist for several days. Authorities continue to monitor the situation and issue health advisories. Staying informed and following safety tips is crucial until conditions improve.

How is climate change linked to these extreme weather events?
Climate change is a major factor behind the increasing frequency and severity of wildfires and heatwaves. Rising global temperatures create drier conditions and longer fire seasons, which contribute to more intense wildfires. These events, in turn, impact air quality and public health, highlighting the urgent need to address climate change.
