Climate change is often associated with illness and environmental destruction, but new research suggests that smoke from wildfires may also be linked to violence in cities.

A study published in the journal Environmental Research Letters shows a correlation between wildfire smoke and an increase in violent assaults in Seattle.

Researcher Lion Kircheis from the University of Konstanz analyzed smoke data from 2013 to 2023 and compared it with police records of assaults.

On days with heavy smoke, the number of assaults rose by nearly 4 percent.

The study also found that assaults increased by 0.5 percent for each additional microgram of fine particulate matter per cubic meter of air caused by wildfires.

During the period examined, wildfire smoke increased the concentration of fine particles in the air by an average of 7 micrograms per cubic meter.

Other explanations examined

The researchers examined whether other factors could explain the rise.

Police response times did not change on smoky days. There were also no additional reports of domestic violence.

According to the researcher, this suggests that the increase in violence is not due to reduced police efforts. Instead, the effect appears to be linked to outdoor areas where people are directly exposed to the smoke.

At the same time, the number of incidents in which police used force increased on the same days as the assaults.

Future implications

In a press release, Lion Kircheis stated that measures to address climate change and improve wildfire management may have implications for public safety beyond health concerns.

He also noted that the burden does not affect everyone equally. Outdoor workers, individuals without access to clean indoor air, and people experiencing homelessness may be particularly vulnerable.

According to the CDC, wildfire smoke is already known to affect health.

The new research suggests that the consequences may be broader, especially if wildfire seasons in North America become longer and more intense.
