In anticipation of the UN plastics treaty talks in Paris, Australian researchers at the Minderoo Foundation release the fist-ever plastics pollution weather forecast: Up to 48 kilograms of nylon, polyester, and car tire particles are estimated to blanket greater Paris every 24 hours. Based on 2015 studies rather than real-time data, the actual numbers are likely much higher, the researchers warn. Still, the forecast app “should sharpen the focus of negotiators,” hopes Minderoo’s Marcus Gover.
