This Day in the History of Helpful, Scientifically Significant Agreements

On this day in 1987, the "Montreal Protocol on Substances that Deplete the Ozone Layer" was signed, agreeing that the production and consumption of most compounds that deplete ozone in the stratosphere, such as chlorofluorocarbons (CFCs), were to be phased out by 2000. It was further adjusted and amended at subsequent Meeting of the Parties between 1990 and 1997. What's happening to the Ozone Layer, especially above Antarctica, unfortunately, has yet to mirror the reduction in CFCs and perhaps won't until 2050, i.e., not in my lifetime. Let's hope that CFCs are indeed the culprit here.
