When the Pope speaks out on climate change, he's not just another world leader spouting off his pet world view. Pope Francis has the straight goods delivered fresh and hot from top officials of the Vatican science academy. When it comes to climate change that means the Potsdam Institute's Hans Joachim Schellnhuber. That's what sets the Pope apart from most leaders including our own. He not only has first rate scientific advisors, he listens to them.
That's why Francis warns our world will "go down" if our political leaders don't finally address climate change. Is anybody listening?
