Using computing resources at NERSC, a team led by Alan Rhoades of the Earth and Environmental Sciences area has found that if global warming reaches around 2.5 degrees Celsius compared to pre-industrial levels, mountain ranges in the California Sierra Nevada and the Andes region of Chile will produce roughly 10% less mountain water runoff, during wet and dry years, to refill reservoirs in the summer months when agriculture and mountain ecosystems most need it. The study points to carbon mitigation strategies to prevent further warming.
We hear about climate models all the time, but how many of us know how they actually work? In this episode, we peel back the curtain, discussing where these models came from, what they can do amazingly well, and their current limitations. And our guests talk about what it’s like for them, personally, when their work is doubted, minimized, or politicized. After all, climate scientists find themselves in the hot seat a lot more often than other scientists. Today’s guests are experts not only in the science itself, but with staying cool under pressure, communicating their science with the public, and laughing off the negativity.
