| The Vatican is hosting a climate change summit that will focus on the need for decisive action to combat global warming as a moral imperative and Christian duty, especially given its impact on poor people. The Protect the Earth, Dignify Humanity meeting in Rome on Tuesday is a precursor to the release of Pope Francis's encyclical on the environment, which is due out in June or July and is expected to centre on the duty of the faithful to address climate change, whatever its causes. |
