Pope Francis called for the world to take action now to address climate change, calling it "a problem that can no longer be left to future generations."

The pontiff, who arrived in Washington yesterday afternoon and spoke in a White House ceremony this morning, praised President Obama for his efforts to reduce air pollution. 

The pope said Catholics in America "are committed to building a society which is truly tolerant and inclusive" and he said that religious freedom "remains one of America’s most precious possessions.”

One day before his address to Congress, the pope said he intends to "offer words of encouragement to those called to guide the nation’s political future."

“Mr. President ... I look forward to these days in your country. God Bless America," Francis concluded.
