Save the Ozone!
</hdr>
<body>
<p>Man-made chemicals keep dissolving earth's shield against UV
rays
</p>
<p> Production of cfcs--the chemicals that attack earth's
precious atmospheric ozone layer and are being phased out by
international agreement--is falling even faster than expected.
That's the good news. The bad news is that cfcs already released
are still drifting up through the atmosphere. New satellite
data, reported in the current Nature, show that ozone levels
over some northern parts of Canada, Scandinavia and Russia were
10% lower this winter than they were just one year ago.
</p>
<p> Since ozone loss can increase the amount of ultraviolet
radiation reaching earth's surface, the risk of skin cancer may
be rising in northern latitudes, as it probably is in
southernmost climes. Scientists hope the level of cfcs in the
upper atmosphere will peak around the year 2000 and then
diminish. What they don't know is how much ozone will be left,
whether the areas of severe ozone depletion will expand toward
population centers, and how dangerous a 21st century day in the
sun will be.
