2004 maximum ozone hole Researchers say the ozone hole over the Antarctic is likely to contract and may disappear by 2050 - as a result of a global reduction of chlorofluorocarbons (CFCs) and other ozone-depleting emissions. The co-author of a paper by the Danish Meteorological Institute in a May 2006 issue of Nature said: "We now have some confidence that the ozone layer is responding to the decreases in chlorine levels in the atmosphere due to the leveling off and decrease of CFCs, and most of the improvements are in agreement with what we had hoped for with the Montreal Protocol in place , " "But we are not out of the woods yet, and the ozone recovery process still faces a number of uncertainties."
