[Ed. – A big middle finger from the environazis to you and your modern life. Of course, no sensible person thinks it’s actually possible to achieve the promised result of preventing 0.5 degrees C of “warming.” The very statement of the objective is meaningless gibberish.]
The deal reached in Kigali, Rwanda, comes after years of wrangling over HFCs—short for hydrofluorocarbons—and could on its own prevent a 0.5°C (0.9°F) rise in temperature by 2100.Scientists say such an achievement could be crucial to the goal laid out in last year’s Paris Agreement of holding global temperature rise below 2°C (3.6°F) by 2100. …
This week’s accord formally comes an amendment to the Montreal Protocol, an agreement crafted in 1989 to protect the ozone layer. The Montreal Protocol required countries to phase out chlorofluorocarbon—or CFC—from use in refrigerators, air conditioners and other uses because it depleted the ozone layer. Most manufacturers replaced CFC with HFCs—leading to a different, if related problem.
Now, countries party to the agreement will have to follow one of three timetables to peak and then reduce their use of HFCs. Developed countries will need to freeze their HFC production and use in 2019 with immediate reductions to follow immediately after that.
