Libby Barnes, like essentially no one else on Forecast, wanted to be a professor from age 12. Specifically, a physics professor. And indeed, climate science almost lost Libby to neutrinos. But an instrumentation disaster, and the associated personal mayhem in the research group, made Libby realize that she was geared more for solving a great many problems, not any one particular decade-long quest. Now, Libby is exploring a dizzying array of topics in climate dynamics, and we bore down into the long-running debate on arctic impacts on the mid-latitudes and subseasonal to seasonal prediction. Along the way, Libby tells Mike about her amazingly sensible — and highly intentional — approach to academia and the tenure process.
In episode 52 of Forecast, Mike and Marilyn Raphael from the University of California at Los Angeles talk about Antarctic sea ice. Arctic sea ice is, on a relative scale, well understood: observations and models show a massive decline. Antarctic sea ice is weirder. Overall, the extent of Antarctic sea ice is increasing, slightly. But this masks nearby areas with both large increases and decreases. Mike and Marilyn discuss the many mechanisms that might be underlying the interesting and somewhat bedeviling trends, as well as the multitude of ways in which Antarctic sea ice interacts with the broader climate system. We wrap up with a personal discussion of what it’s like being an introvert in science, and some ways to navigate the often-draining interpersonal demands.
