Ozone-destroying chlorine tops out
Article Abstract:
Atmospheric chemist Stephen Montska reports that atmospheric chlorine levels have peaked and begun to decline, which should enable the ozone layer to begin recovering by 2000. The decline is apparently due to the Montreal Protocol, an international agreement to restrict the use of chemicals that destroy ozone.

At quadrennial geophysics feast, earth scientists think globally
Article Abstract:
Harry van Loon and James Hurrell have linked Pacific Ocean temperature changes around 1980 with the Antarctic ozone hole. The Total Ozone Mapping Spectrometer satellite has confirmed that ozone depletion is causing a dramatic rise in UV radiation reaching the earth.

The ozone hole reaches a new low
Article Abstract:
Measurements of the ozone layer over Antarctica during the 1993 Southern Hemisphere spring reveal 15% less ozone than in 1992. Scientists blame lingering debris from the 1991 Mount Pinatubo eruption and abnormally cold temperatures at high altitudes.
