Good news from Antarctica: The hole in the ozone layer is
shrinking, new measurements reveal.
Ozone is a molecule made of three oxygen atoms. It's relatively
highly concentrated in a particular layer of the stratosphere
about 12 miles to 19 miles above Earth's surface. This ozone
layer prevents ultraviolet light from reaching Earth's surface —
a good thing, given that UV light causes sunburn and skin cancer.
Ever since the early 1980s, though, a hole in this layer has
developed over Antarctica during September to November,
decreasing ozone concentration by as much as 70 percent. The
cause is human-produced chlorofluorocarbons (CFCs), which were
once heavily used in aerosols and refrigeration.
By international agreement, CFCs have been phased out of use.
The policy has real effects, new satellite observations reveal.
In 2012, the hole in the ozone layer over Antarctica was smaller
than it has ever been in the last 10 years.
The new observations, announced by the European Space Agency
(ESA) on Feb. 8, come from Europe's Met Op weather satellite,
which has an instrument specifically designed to sense ozone
concentrations. The findings suggest that the phase-out of CFCs
is working, the ESA reports.
Antarctica is particularly vulnerable to ozone-depleting
substances, because high winds cause a vortex of cold air to
circulate over the continent. In the resulting frigid
temperatures, CFCs are especially effective at depleting ozone.
The result is that people in the Southern Hemisphere are at
increased risk of exposure from UV radiation.
CFCs persist in the atmosphere for a long time, so it may take
until the middle of the century for ozone concentrations to
rebound to 1960s levels, the ESA reports. However, the hole in
the ozone over Antarctica should completely close in the next
few decades.

Are you obligated as an armed civilian, to defend unarmed
liberals while you are both under fire by foreign agents of the
outlaw Obama administration?
No. Shoot the liberals immediately so they can't stab you in
the back while you are defending yourself, then return a
controlled rate of aimed fire.
