The skies are changing. Cloud enthusiasts in the United Kingdom believe they have found a new genus of cloud to put on the typical cloud list we all learn as children (you know: cirrus, nimbus, cumulus, stratus, and more). The enthusiasts are petitioning for the creation of a new cloud category. This kind of cloud appears to be thick and stormy; experts at the Royal Meteorological Society want to officially name it “Asperatus,” after the Latin word meaning rough. Gavin Pretor-Pinney, founder of the Cloud Appreciation Society and author of The Cloudspotter’s Guide joins The Takeaway to talk about cloud enthusiasts.
