By Somini Sengupta, The New York Times. For GSS Ozone chapter 10 and Climate Change chapter 9. Excerpt: UNITED NATIONS — Hydrofluorocarbons. It’s a mouthful of a name for a chemical that keeps the turkey frozen in our refrigerators and also heats up the planet. Now, a landmark international agreement to eliminate HFCs, as the chemicals are better known, is poised to come into effect. On Friday, Sweden became the 20th country to ratify the treaty.... That meets the threshold for the agreement to enter into force... January 1, 2019. It requires every country in the world to phase out the use of HFCs, compounds that are regarded as a sort of greenhouse gas on steroids, able to trap much more heat in the atmosphere than carbon dioxide. The agreement was reached, after seven painstaking years of negotiations, in October 2016 in Kigali, the capital of Rwanda. Known as the Kigali Amendment to the Montreal Protocol, it required 20 countries to ratify it in order to go into effect — just in time for a global meeting on a broader treaty designed to protect the ozone layer, which starts next week in Montreal. ...the ratification sends a message to companies that make the compounds and to companies that use coolants in their products that they will have to come up with alternatives. ...The United States has not yet ratified the measure, ...and if it fails to ratify the agreement, it could potentially hinder the ability of American companies to sell coolants to other countries that have ratified the agreement. ...China, a leading manufacturer of household appliances that contain HFCs, hasn’t yet ratified it either, but is expected to, Mr. Zaelke said.... https://www.nytimes.com/2017/11/17/climate/hfcs-montreal-protocol.html
