These clouds accelerate chemical reactions that break down ozone ... like the Montreal Protocol have curbed ozone depletion, the persistence of CFCs means recovery is slow but steady.

The ozone layer over Antarctica ... vulnerable to accelerated ozone depletion from chlorine accumulation. Recent research, however, has provided a glimmer of hope for the future of the ozone layer.

In 1990, Margaret Thatcher urged further support for the Montreal Protocol so that CFCs could be phased out completely and developing nations could afford ozone friendly technologies.

In 1985, scientists discovered a "hole" in the ozone layer over Antarctica that opened up during the austral spring, between September and December. This seasonal ozone depletion was suddenly ...

Research on CFCs' climate impacts beyond ozone depletion is scant, even though they can trap more heat than climate change poster child carbon dioxide, the study notes. The study's findings not ...

The study suggests that the reduction of ozone depleting substances, called chlorofluorocarbons ... might see a year when there's no ozone hole depletion at all in the Antarctic.

Later amendments to the Montreal Protocol completely phased out production of CFCs. Past studies have used statistical analyses of changes in the ozone hole’s size to argue that ozone depletion ...

These clouds accelerate chemical reactions that break down ozone molecules. In contrast, ozone depletion is minimal ...
