Saturday on PBS News Weekend, rescue efforts are underway in Morocco as the death toll from a devastating earthquake surpasses 1,300. Then, with gun suicides at an all-time high, we examine what can be done to reverse this sobering trend. We also look at Africa's first climate summit and what it means for the continent's future. Plus, a new report sheds light on the impact of invasive species. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
