Tornadoes, paralympic veterans, Sudan
We explore whether climate change has played a role in this deadly season of tornadoes. We also feature the story of an Iraq War Veteran, who became a world-class athlete. Continuing with our "Shrinking Cities" series, we visit Youngstown, Ohio, a city that is trying to cope with population loss. And New York Times East Africa Bureau Chief Jeffrey Gettleman discusses the violence in South Sudan.
