(PhysOrg.com) -- Aircraft emissions can affect the properties of cirrus clouds, contributing to climate change. This was a key finding from PNNL scientist Dr. Xiaohong Liu and his colleagues from a recent study. The team concluded that black carbon and/or metallic material from airplane exhaust could affect radiant heat and climate by acting as efficient sources for making ice crystals, thus affecting the creation of cirrus clouds.
