By the 2070s, climate change will reduce snowpack and increase extreme rainfall in the Sierra Nevada and California’s reservoirs will likely be overwhelmed. That’s according to a new study by UCLA climate scientists, who predict that run-off during so-called atmospheric rivers  will increase by nearly 50 percent, leading to widespread flooding across the state. We’ll talk about the impact of climate change on Sierra weather patterns and what it all means for the state’s water supply.
