    German scientists say solar activity delaying ozone repairs

    According to this article, from today's Guardian, a change in solar activity will affect the rate at which the ozone layer can naturally recover:

    Martin Dameris, who led the research at the Institute for Atmospheric Physics in Wessling, said: "The ozone hole will stay around for another four to five years. We can't expect it to start to recover until 2010 and then it will take another 40 to 50 years to repair completely." Ozone depletion is a largely forgotten problem since the Montreal protocol successfully reduced levels of CFC chemicals in the atmosphere, after British scientists in Antarctica reported they were destroying ozone. But some experts have been puzzled by the layer's slow recovery.
