Pope Francis arrived in DC this morning for his first visit in the U.S. and he addressed the crowd at the White house following President Obama’s ‘welcome speech’. In his speech, the Pontiff reiterated his concerns over  air pollution and encouraged the President’s initiative to address it.

Mr. President, I find it encouraging that you are proposing an initiative for reducing air pollution. Accepting the urgency, it seems clear to me also that climate change is a problem which can no longer be left to a future generation. When it comes to the care of our”common home,” we are living at a critical moment of history. We still have time to make the changes needed to bring about “a sustainable and integral development, for we know that things can change” (Laudato Si’, 13). Such change demands on our part a serious and responsible recognition not only of the kind of world we may be leaving to our children, but also to the millions of people living under a system which has overlooked them. Our common home has been part of this group of the excluded which cries out to heaven and which today powerfully strikes our homes, our cities and our societies. To use a telling phrase of the Reverend Martin Luther King, we can say that we have defaulted on a promissory note and now is the time to honor it.
