Excerpt: The aviation industry has long been criticized for its large environmental footprint, particularly its climate-warming carbon emissions. But a new study suggests that another byproduct of airplanes—the white contrails they paint across the sky—has an even bigger warming effect, one that is set to triple by 2050. ...A 2011 study suggests that the net effect of these contrail clouds contributes more to atmospheric warming than all the carbon dioxide (CO2) produced by planes since the dawn of aviation. And those effects are predicted to get worse as air traffic—and the resulting cloud coverage—increases: Some estimates suggest global air traffic will quadruple by the year 2050....
