File Repairing our ozone layer
In 1987, delegates from around the world signed the Montreal Protocol designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. This recent video illustrates the results of the Protocol, which is considered to be one of the most successful international environmental agreements.

Protecting the ozone layer while also preventing climate change
Forty years ago, scientists warned that a hole in the layer of ozone surrounding the earth could have serious effects on human health and the environment. This problem is being solved thanks to a global agreement to stop the use of ozone-depleting chemicals that damage the ozone layer. But now scientists are concerned that the substances used to replace these ozone-depleting chemicals are acting to trap heat inside the earth, exacerbating the greenhouse effect. Can policymakers protect the ozone layer while also helping prevent climate change?

Figure Maximum historical depletion over the south hemisphere (9 September 2000) and over the North hemisphere (15 March 2011)
Note: False-colour view of total ozone over the Arctic and Antarctic poles. The purple and blue colours indicate lowest ozone presence, while yellow and red indicate higher ozone presence. Ozone concentration is commonly measured in Dobson Units. One Dobson Unit is the number of molecules of ozone that would be required to create a layer of pure ozone 0.01 millimetres thick at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere.
