As I briefly discussed in a previous blog, the Paris Agreement -- the world's first comprehensive climate agreement -- came into force on November 4, 2016 (about 2 weeks before this article was written). 109 heads of sovereign states agreed to the agreement, including China and the United States. The Atlantic did a phenomenal job of summarizing the implications of the Paris Agreement, and I will first briefly summarize their points in order to contextualize the importance of this moment in history.
