Microbes make microplastics more likely to form ice in clouds, research reveals

Tiny pieces of plastic, called microplastics, are showing up everywhere, even in the water in clouds, rain, and snow—and they may be affecting our weather and temperatures. A study published in Environmental Science & Technology and led by Hosein Foroutan, associate professor of civil and environmental engineering, found that microbes living on microplastics dramatically boost their ability to trigger ice formation in clouds.
