Some might look at this problem as Mission: Impossible. Not so, however, for the National Black Leadership Commission on Health when it comes to tackling the huge disparities that continue to exist around the health of black Americans.

The U.S. is a nation of islands--from Puerto Rico to Guam to Nantucket and more. But, the fate of these islands and the millions who live on them is at risk because of climate change. Think rising sea levels, increased frequency/intensity of storms and warming waters. My show this week is a prelude to Climate Week NYC and UN climate talks. I sit down with CBS News Weather Expert Jeff Beradelli and Arturo Garcia-Costas from NY Community Trust to assess first-hand how big this crisis really is, and what citizens can do.

What's the answer to America's obsession with guns? Will Congress take action when it returns this month in response to multiple mass shootings over the summer in Texas, Ohio and California?

Deanna Hollas, who recently was installed in the Presbyterian Church as Minister of Gun Violence Prevention, and she talks about her new mission.

The turn from summer to fall, in many ways is a call to get serious again. Time for thinking about the future? To consider how each one of us can make a difference. Cross Currents host Scott Widmeyer offers up 6 Questions for us to ponder, and hopefully take action on.
