There is growing evidence that plastic pollution can exacerbate the impact of many planetary boundaries, including climate change, ocean acidification, altered biogeochemical flows and biosphere integrity. We know that plastic pollution causes microplastic and nanoplastic particles to be transported in our atmosphere, however there is still a lot of uncertainty around the distribution of these particles in the atmosphere and their impacts on atmospheric warming. This new publication offers supporting evidence that plastic particles present in the atmosphere can absorb light and so may lead to increased atmospheric warming, though we need more evidence before we can confidently conclude the impacts of plastics on climate change.
