The Rio Grande River is an important source of water for citizens of both the United States and Mexico, with millions of people depending on the waterway for drinking supplies and agriculture as it weaves its way across the shared border between the two countries. But climate change is having a deep impact on the Rio Grande, even as more people move to the region. The area surrounding the Rio Grande is experiencing longer lasting droughts, with some estimates predicting that the river will run out of water by 2060. Zoƫ Schlanger, an environmental reporter with Quartz, worked on a nine-part series with the Texas Observer that explores issues of border water and climate change. NewsHour Weekend's Hari Sreenivasan recently spoke to Schlanger about the challenges facing the Rio Grande.
