As the planet warms, changing weather patterns are only one effect. Warming air is often more toxic, leading to asthma and even heart attacks. A better understanding of these air quality changes can help society mitigate their consequences. Georgia Tech researchers, including School of Earth and Atmospheric Sciences Professor Rodney Weber and Assistant Professor Pengfei Liu, are innovating ways to study air quality — beginning with prehistoric insights and zooming all the way to satellites in our orbit.
