New research sheds light on health effects of wildfire smoke

A new UCLA study found that more people that previously counted die each year in California from long-term wildfire smoke exposure. The research, published in the journal Science Advances, found that inhaling fine particulate matter from wildfires contributed to as many as 55,700 deaths between 2008-2018. KTVU's Heather Holmes and Alex Savidge discuss the findings with UCLA professor of environmental health sciences and senior author of the study, Michael Jerrett.
