Scientists reveal how landmark CFC ban gave planet fighting chance against global warming

New modelling by the international team of scientists paints a dramatic vision of a scorched planet Earth without the Montreal Protocol, what they call the 'World Avoided'. This study draws a new stark link between two major environmental concerns -- the hole in the ozone layer and global warming. The research team reveals that if ozone-destroying chemicals, which most notoriously include CFCs, had been left unchecked then their continued and increased use would have contributed to global air temperatures rising by an additional 2.5°C by the end of this century.
