Microplastics are absorbing heat in the atmosphere and contributing to global warming , a new study reveals. Microplastics are infamous for being everywhere , contaminating ecosystems and accumulating inside our bodies . Scientists have known for a while that plastics are also blown high into the atmosphere, where they are now pervasive, but it was unclear what impact they might be having up there. Study co-author Drew Shindell , a distinguished professor of Earth science at Duke University, told Live Science that the climate change impact of plastic particles is fairly small — comparable to the emissions of a small country. In numbers, this is the equivalent of around a couple of percent of the contribution from carbon dioxide (CO 2 ) — the main driver of climate change — or a couple hundredths of a degree of warming. However, the researchers' modeling was based on a limited understanding of the amount of plastic in the atmosphere, so the extent of the warming effect is uncertain.…
