 Climate change has been linked to increased levels of air pollutants including fine particulate matter, PM underscore 2.5. This type of pollution can cause serious health problems when people are exposed to it over long periods of time. The researchers examined data from 698 counties in the US from 1999 to 2018 to determine how much higher rates of death there were among those who have been exposed to higher levels of PM underscore 2.5. They found that people who lived in areas where the level of PM underscore 2.5 was higher experienced higher rates of death from all causes including heart disease and respiratory illnesses. The researchers also found that certain groups such as older adults, blacks and men were more likely to experience higher rates of death than others. Additionally, they found that the effect of PM underscore 2.5 on mortality varied depending on the region of the country. This article was authored by Austin Rao as or a body Mark B.
