We can’t do much to prevent losing more communities to wildfires, and we certainly can’t reduce the scale of fires in the boreal forest. But we can minimize the health impacts of wildfire smoke, which should help us deal with the economic impact of wildfires and other climate disasters. …First, we need to minimize the damage of PM2.5 and other particles in wildfire smoke. That would involve more airtight homes, workspaces and schools, plus air purifiers in every room and office. In new construction, air purification should be built right into the heating, ventilation and air-conditioning systems. Second, we need to start using N95 masks whenever air quality drops. …Third, we need to recognize that wildfires and heat waves can threaten electricity grids by damaging transmission lines. The remedy here would be installing enough solar power in homes and workplaces. …We will also have to prepare for long-term health consequences of wildfires.
