Report of 2010 Assessment of the Scientific Assessment Panel -- UNEP

This report from the United Nations Environmental Programme's Scientific Assessment Panel finds that changes in stratospheric ozone are linked to the Earth’s climate. The report finds that over the past decade, global ozone levels, and ozone levels in the Arctic and Antarctic regions are at a turnaround point — no longer decreasing but not yet increasing. The abundances of ozone-depleting substances in the atmosphere are responding as expected to the controls of the Montreal Protocol, with many now declining in both the lower and upper atmosphere."
