Watch the world choke on CO2 in eerie NASA videos of manmade emissions

Earth, with South America and the Pacific Ocean. The northern hemisphere is covered in swirls of a dusty sand color, with darker wisps reaching down into the southern half of the globe.

Earth is being choked by a thick, curling fog of carbon dioxide that coats the planet as the months go by, a series of NASA videos shows. The newly released animations visualize the astonishing scale of human carbon dioxide (CO2) emissions over a year by coloring the invisible greenhouse gas.
