Exposure to dangerous pollution caused by wildfires is escalating and shows no sign of abating, according to a recently published study. This comes at a time when scorching hot and dry weather conditions globally are increasing the risk of wildfire outbreaks.
The study reveals that air pollution resulting from fires can have severe health consequences, including heart and lung damage, and even death. The research further shows that the number of people exposed to significant pollution from wildfires for at least one day a year has risen by nearly 7%, reaching over 2 billion individuals between 2010 and 2019. On average, people experience almost 10 days of exposure to this pollution annually.
These findings are particularly relevant in light of the record-breaking heat the world has experienced, with this summer being recognized as the hottest on record. The devastating wildfires that have made headlines in recent months, from Maui to Greece to North America, serve as a clear reminder of the urgency to address this issue. As extreme weather events become more frequent worldwide, Australia is bracing itself for an intense bushfire season.
What is concerning is that low-income countries bear the brunt of the air pollution resulting from wildfires. The study reveals that these countries are exposed to levels of pollution that are about four times higher than those in high-income countries. Central Africa, Southeast Asia, South America, and Siberia are particularly susceptible to high risks of wildfire-induced air pollution.
The inhalation of wildfire smoke has been previously linked to detrimental health effects, such as premature labor, low birth weight, impaired lung development, and increased reliance on prescription medication during childhood. These findings highlight the need for urgent action to mitigate the impact of wildfires on air quality and public health.
