Every six to eight years the United Nations Intergovernmental Panel on Climate Change, the IPCC, undertakes a massive review of the latest science around climate change. Right now, we are near the end of one of these cycles of scientific review.  My guest today, Ryan Hobert, is the managing director of the United Nations Foundations climate and environment team. We kick off discussing the process behind these IPCC reports before diving deep into some of the specific findings of the latest report, released Monday.
