What is PM2.5 and why is it dangerous?
PM2.5 refers to tiny particulate matter less than 2.5 micrometers in diameter. These particles can penetrate deep into the lungs and bloodstream, causing respiratory and cardiovascular problems. Wildfire smoke significantly increases PM2.5 levels, posing serious health risks especially for vulnerable populations.

How do wildfires impact air quality around the world?
Wildfires release large amounts of PM2.5 and other pollutants into the atmosphere, which can travel thousands of miles. This means that even areas far from the fires can experience poor air quality, leading to health issues and environmental damage globally.
-
In what ways does climate change increase wildfire risks?
Climate change causes higher temperatures and drier conditions, creating ideal environments for wildfires to ignite and spread. As global temperatures rise, the frequency and severity of wildfires are expected to increase, further worsening air pollution.
-
What technological tools are used to track wildfire pollution?
Advanced satellite technology and AI-powered tools like Climate Trace enable real-time monitoring of pollution sources. These innovations help scientists and policymakers understand the scale of wildfire emissions and develop strategies to mitigate their impact.
-
What can be done to reduce wildfire pollution and protect health?
Reducing greenhouse gas emissions, improving land management, and investing in early warning systems are key steps. Public health measures, such as air quality alerts and air filtration, can also help protect communities from the harmful effects of wildfire smoke.
