Sun Storms Deplete Ozone, Too

An anonymous reader writes "Turns out the sun itself zaps the ozone that protects us from the sun. LiveScience is reporting that the record-setting string of solar storms around Halloween in 2003 (including an X28 flare) set off a cascade of events that depleted the ozone layer over the Arctic in early 2004. In a nutshell, more nitrogen was created, and an unusually strong vortex of high-speed winds aloft brought the nitrogen down, where it contributed to cutting ozone by 60 percent over the polar region. In January, the a European scientist warned residents of the far north to basically stay out of the sun. While chlorofluorocarbons are still blamed for ozone depletion, scientists said this study shows they don't properly account for the sun's impact."
