Ozone Level Fell 5% From 1979 to 1986
|
The ozone content of Earth's atmosphere declined about 5 percent
between 1979 and 1986, according to the first report from an effort
to monitor ozone levels worldwide.
The decline was as high as 30 to 40 percent over the poles-where,
during a seasonal Antarctic "ozone hole," more than 60 percent of the
ozone was depleted-and as low as zero over the tropics. Over the
United States ozone levels were down between 0.5 and 1 percent.
Ozone molecules in the stratosphere, six to 20 miles up, absorb
much of the sun's ultraviolet light, preventing potentially harmful
amounts from reaching the ...
