From Phys.org, by Dorany Pineda:
Extreme heat and wildfire smoke are independently harmful to the human body, but together their impact on cardiovascular and respiratory systems is more dangerous and affects some communities more than others.
A study published Friday in the journal Science Advances said climate change is increasing the frequency of both hazards, particularly in California. The authors found that the combined harm of extreme heat and inhalation of wildfire smoke increased hospitalizations and disproportionately impacted low-income communities and Latino, Black, Asian and other racially marginalized residents.
