OzonAction Info Team took the opportunity to tackle the issue of the Arctic ozone loss during the Antarctic Ozone Hole Side Event today.

Indeed, Professor Jonathan Pyle from University Cambridge delivered a presentation on the Arctic Ozone Loss. About 20km (13 miles) above the ground, 80% of the ozone was lost in 2011. The cause was an unusually long spell of cold weather at altitude. In cold conditions, the chlorine chemicals that destroy ozone are at their most active.
