Montreal Protocol mitigated global warming



Canberra, Dec. 11-  The 1987 Montreal Protocol, which banned substances that deplete the ozone layer, mitigated the global warming process the planet is currently experiencing, says a study by the Australian University of New South Wales.

The research, published in Environmental Research Letters, concludes that this agreement mitigated the impacts of global warming for more than three decades, overcoming some treaties aimed at improving the effects of climate change.

According to this study, it was determined that by mid-century the Earth will be, on average, at least one degree Celsius colder than it would have been without the aforementioned agreement, while the weakening is even greater in regions such as the Arctic, where warming avoided will be between three and four degrees

Chlorofluorocarbons (CFCs) are greenhouse gases thousands of times more potent than CO2, so the Montreal Protocol not only saved the ozone layer but mitigated a substantial fraction of global warming, said lead author of the article, Rishav Goyal .

In his opinion, this Protocol had a much greater impact on global warming than the Kyoto Agreement, specifically designed to reduce greenhouse gases.

In this regard, he commented that the measures adopted as part of the Kyoto Agreement will only reduce temperatures by 0.12 degrees in the middle of the century, compared to a degree of mitigation of the Montreal Protocol. (Prensa Latina)
