Pope Francis Says Climate Change Cannot Be Ignored

Pope Francis said Wednesday that climate change is a problem that can't be left to future generations. Speaking deliberately in English at a White House ceremony, the pope said he was encouraged that President Barack Obama has put forward a plan to reduce air pollution. Francis urged more attention be paid to the millions in poverty now overlooked by society, quoting Martin Luther King: "We have defaulted on a promissory note, and now it is time to honor it." Francis said he will encourage Congress to guide the U.S. in fidelity to its founding principles, including religious liberty. He referred only briefly to the issue of immigration, saying that "as a son of an immigrant family, I am happy to be a guest in this country, which was largely built by such families."
