Large hole opens in ozone layer above North Pole
This handout photo provided by The National Oceanic and Atmospheric Administration (NOAA) shows Arctic sea ice in 2013. The Arctic isn't nearly as bright and white as it used to be because of more ice melting in the ocean, and that's turning out to be a global problem, a new study says. With more dark, open water in the summer, less of the sun's heat is reflected back into space. So the entire Earth is absorbing more heat than expected, according to a study published Monday in the Proceedings of the National Academy of Sciences. (AP Photo/NOAA) | Uncredited

A large hole appeared in the ozone layer over the Arctic, one of the largest recorded in the area.

The expansive hole was caused by cold temperatures in the atmosphere above the North Pole. Clouds then formed in the atmosphere, allowing gases to interact with ultraviolet rays to produce ozone-destroying chemicals such as chlorine and bromine atoms.
