New research published in Nature Climate Change reveals that colored microplastics in the atmosphere absorb sunlight and trap heat. While the global impact is currently smaller than black carbon, the warming effect is significantly higher in plastic-dense regions like the Great Pacific Garbage Patch. Scientists found that as plastic waste breaks down and enters the air, these particles act as heat traps. This discovery suggests that current climate models may need updates to account for the warming contributions of atmospheric plastic pollution.
