Charles Koven is a staff scientist in the Climate Sciences Department and modeling lead in the NGEE-Tropics project. His research focuses on the relationship between climate change and Earth’s carbon cycle.
Jennifer Holm is a research scientist in the Climate and Ecosystem Science Division and a collaborator in the NGEE-Tropics project. Her research focuses on modeling terrestrial ecosystems, with an emphasis on tropical forests.
Michael F. Wehner is a senior scientist in the Computational Research Division researching the behavior of extreme weather events in a changing climate, especially heat waves, intense precipitation, drought, and tropical cyclones.
As the world warms, extreme weather events grow – and they also change. Berkeley Lab researchers found that climate change is shifting snowfall to rainfall on mountains across the Northern Hemisphere. Those surges of liquid water bring a distinct set of dangers, including floods, landslides, and soil erosion.
As another atmospheric river impacts California on January 4th and 5th — with more rain forecast after that — Michael Wehner, a senior scientist in the Computational Research Division at Lawrence Berkeley National Laboratory, discusses how climate change is increasing the rainfall from these drenching storms and how people can better prepare. Wehner uses observational data and advanced computer modeling to understand the behavior of extreme weather events in a changing climate, especially heat waves, intense precipitation, drought, and tropical cyclones.
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.
