Researchers in Japan have confirmed microplastics are present in clouds, where they are likely affecting the climate in ways that aren't yet fully understood.
In a study published in Environmental Chemistry Letters, scientists climbed Mount Fuji and Mount Oyama in order to collect water from the mists that shroud their peaks, then applied advanced imaging techniques to the samples to determine their physical and chemical properties.The team identified nine different types of polymers and one type of rubber in the airborne microplastics -- ranging in size from 7.1 to 94.6 micrometers.

These tiny fragments have been discovered inside fish in the deepest recesses of the ocean peppering Arctic sea ice and blanketing the snows on the Pyrenees mountains between France and Spain.
