chlorofluorocarbons

A recent study shows that the ozone layer in the Antarctic is beginning to shrink.

A new study found that four new artificial gases have appeared in the atmosphere.

Scientists discovered ozone holes in Antarctica that are in the process of self-sufficiency, at least a decade earlier than they had previously expected.

The ozone layer is tending to be very small and is able to restore the situation in 1980 in the middle of this century, according to a recent report by UN scientists.
