Microplastics Promote Cloud Formation, with Likely Effects on Weather and Climate

Clouds in the atmosphere can be made up of liquid water droplets, ice particles or a mixture of the two.

Microplastics Promote Cloud Formation, with Likely Effects on Weather and Climate

Clouds form when water vapor – an invisible gas in the atmosphere – sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, we show that microplastic particles can have the same effects, producing ice crystals at temperatures 5 to 10 degrees Celsius (9 to 18 degrees Fahrenheit) warmer than droplets without microplastics.

This suggests that microplastics in the air may affect weather and climate by producing clouds in conditions where they would not form otherwise.
