NASA data reveals global water crisis

Pope Francis officially released his encyclical today on Climate Change. The Papal letter was leaked earlier this week and has been very controversial. In it, the Pope says the environment is in crisis and he calls on humanity to mend the problem. The announcement comes as two new studies, based on a decade of data from NASA, reveal one-third of the World’s largest aquifers are in serious danger and most of them struggle to keep up with growing demands for fresh water. We talk about the crisis with Alexandra Richey, lead author on both aquifer studies. (Photo: Flickr/NASA)
