KOLKATA, India, Jan. 6 (UPI) -- A new image from NASA's Earth Observatory mission shows what happens when widespread pollution meets a temperature inversion.
Currently, a massive blanket of haze hangs over the Indo-Gangetic Plain. The smog is a the result of industrial pollution and urban exhaust, as well as agricultural, cooking and trash fires. Skies in northern India and Bangladesh are darker than usual as the haze shields the sun.
