Pollution for All
When we talk about natural processes—especially atmospheric—nothing is too small to be irrelevant. Recently, researchers in Brazil and the United States found that nanoparticles of pollution play an outsize role in cloud formation and disruption, altering rain cycles even in pristine forest areas.
The study, published in Science Advances, showed that human-made aerosols smaller than 10 nanometers, previously thought to be too tiny to act as cloud condensation nuclei or have any influence on climate processes, can become climatically active as they swell on their way to the upper layers of Earth’s atmosphere.
