As Pope Francis gets into high gear on his visit to the United States, it’s worth reviewing details and contexts in the extraordinary message to Catholics and the rest of the planet in “On Care for Our Common Home,” the encyclical he issued earlier this year.

As the world prepares for a pivotal climate conference in Paris this December, countries are offering their national plans to tackle a changing climate. These plans, known as intended nationally determined contributions (INDCs), contain details of what each country is prepared to do as part of a new global climate agreement.
