Ozone Layer Rebuilding???

Earth's formerly thin ozone layer is recovering Wed Aug 30, 6:31 PM ET

WASHINGTON (Reuters) - Earth's protective ozone layer, which was notably thinning in 1980, may be fully recovered by mid-century, climate scientists said on Wednesday.

Ozone in the stratosphere, outside the polar regions, stopped thinning in 1997, the scientists found after analyzing 25 years worth of observations.

The ozone layer shields the planet from the sun's harmful ultraviolet radiation, but human-made chemicals -- notably the chlorofluorocarbons found in some refrigerants and aerosol propellants -- depleted this stratospheric ozone, causing the protective layer to get thinner.

The scientists said the ozone layer's comeback is due in large part to compliance with an 1987 international agreement called the Montreal Protocol, which aimed to limit emissions of ozone-depleting chemicals.

    The ozone layer waxes and wanes naturally.

    The earth's temperatures wax and wane naturally as well.

    Mother Nature is an amazingly adept caretaker of the Earth, and we humans are a bit narcissistic to think that we're destroying it every time we experience a "change."
