Young people are meeting in New York on Monday at the United Nations Youth Climate summit led by 16-year-old Swedish climate activist Greta Thunberg. Meanwhile, US President Donald Trump is not attending the climate summit. Instead, Trump convened a session at the UN on worldwide religious freedom and persecution. Plus, host Carol Hills speaks with Samantha Power, former UN ambassador under President Barack Obama, about the unintended consequences of the Obama administration's intervention in Libya and the failure to act decisively in Syria. And, travel company Thomas Cook is no more. The British firm, the world's oldest, announced that it is shutting down, canceling all flights and vacations and stranding hundreds of thousands of travelers.
