We look at the findings of a new report suggesting that climate change might make it increasingly difficult in the decades ahead to find a city suitable for hosting the Winter Olympics. We also hear how American evangelists and missionaries are whipping up anti-gay sentiment in Russia and elsewhere overseas. A young woman who escaped domestic servitude discusses America’s modern-day slavery problem. The story of how a photo-journalist got her editors in the US to pay attention to refugees from South Sudan by focusing her lens on the refugees’ shoes. And novelist Gary Shteyngart on growing up as an émigré from Soviet Russia in 1980s America.
