Representatives of the seven Colorado River Basin states meet today at a conference in Las Vegas to discuss the details of a long-awaited plan for dealing with drought. Cities, farms, and tribal nations are negotiating voluntary cutbacks in water use to reduce the risk of Lake Mead falling to catastrophically low levels. KNAU’s Melissa Sevigny spoke with one of the conference moderators, John Fleck, a water expert from the University of New Mexico, about why this “Drought Contingency Plan” is needed.

A report from the United Nation’s Intergovernmental Panel on Climate Change says the planet has already warmed by one degree Celsius due to human activity since the Industrial Revolution and it’s on track to get hotter. Thousands of experts contributed to the report, which warns the world’s carbon emissions need to reach “net zero” by the year 2050 to avoid catastrophic environmental changes. KNAU’s Melissa Sevigny spoke with Northern Arizona University scientist Christina Schädel about the findings.
