Timely Decision Helps Save Global Climate Crisis.

Back in 1987, world leaders came together to ban chlorofluorocarbons (CFCs), which are the chemicals associated with the gigantic, gaping hole in the ozone layer that persisted for decades.

And it’s a good thing that they did. Research published in the journal Nature on Wednesday found that a world in which the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer treaty never happened, the planet would be in horrible shape. In the present-day of that hypothetical world, we would already be living through some of the worst-case, nightmare scenarios.
