Brazil just ratified the Paris Agreement

In order for the landmark deal to enter into force, 55 countries representing 55 percent of global emissions must ratify it. Not counting Brazil, the totals so far are 27 (mostly small, with the exception of the United States and China) countries and 39.08 percent. There's hope that the addition of the world's 7th-largest emitter will encourage other countries to get a move on. Washington Post
