How a 1988 emissions deal helped slow climate change

"The study makes clear that efforts to reduce greenhouse gas emissions -- like a recent international plan to phase out hydrofluorocarbons, a group of cousin chemicals to CFCs that are used in air conditioners and refrigerators, and the Obama administration's move this year to impose strict new limits on emissions from power plants -- can have a big payoff," Tim McDonnell writes.
