Climate change: Global deal reached to limit powerful greenhouse gases

Nations agreed to limit the use of HFCs,
 used in air conditioners and refrigerators.

Nearly 200 nations have reached a deal to limit the use of greenhouse gases far more powerful than carbon dioxide in a major effort to fight climate change.

The talks on hydrofluorocarbons, or HFCs, were called the first test of global will since the historic Paris Agreement to cut carbon emissions was reached last year.

HFCs are described as the world's fastest-growing climate pollutant and are used in air conditioners and refrigerators.

The agreement caps and reduces the use of HFCs in a gradual process beginning by 2019, with action by developed countries including the United States, the world's second-worst polluter.
