What happened

May 5, 2026 report Colored microplastics could be making global warming worse Paul Arnold Author Sadie Harley Scientific Editor Robert Egan Associate Editor There's more bad news about microplastics.

Why it matters

We already know they pose a risk to health and can pollute ecosystems, but now researchers have discovered that tiny plastic particles drifting in Earth's atmosphere could be a significant contributor to global warming.

Common ground

According to a paper published in the journal Nature Climate Change, airborne microplastics trap nearly one-fifth as much heat as black carbon, also known as soot.
