Forecast: climate conversations with Michael White
Summary: Michael White, Nature's editor for climate science, chats with climate scientists about their work and lives. Guests will include everyone from grad students to the most senior people in the field. Topics will include climate change, models, paleoclimate, IPCC, projections, uncertainty, El Nino, monsoons, aerosols, sea level rise, ocean circulation, glaciology, modes of variability -- pretty much any part of the physical climate systems. Impacts and policy are also in the mix. All views are those of the host and guest.

Understanding climate models If you’ve heard about any climate cycle, it’s probably the El Niño Southern Oscillation, or ENSO. 2015/2016 is looking like it might bring a record El Niño, and media coverage is, for climate, pretty remarkable. The coverage is understandable, as weird things happen during big El Niños. The eastern tropical Pacific Ocean is anomalously warm during boreal winter. Deep convection moves away from the Western Pacific Warm Pool, and other bits of the climate system tend to shift to unusual states. Sometimes! My house in northern California might flood this winter, but then again it might not. Even though ENSO is correlated with climate variations all over the place, the explained variance is often small. Pretty much every big El Niño is its own beast, and the field is still working towards a prediction system that has skill at more than seasonal time scales. Decadal- to centennial-scale projections remain uncertain. Mat Collins, from the University of Exeter, is one of the world’s leading authorities on ENSO. As we discuss in episode 2 of Forecast, while many aspects of ENSO predictability indeed haven’t gotten much better, other aspects are now far better understood. Mat and I also discuss how working with the Intergovernmental Panel on Climate Change is like dealing with a hangover, atmospheric circulation on Mars, uncertainties in climate modeling, and how to talk to a statistician.

The highs and lows of Antarctic science For my first interview, I met with Martin Siegert, who I’ve known for a few years from meetings and a visit to the University of Edinburgh. Martin is the co-director of the Grantham Institute, a well-known climate institute based at Imperial College London, with a goal to, at least in part, bring climate science into a broader societal discussion. Martin is best known for his work as a glaciologist, particularly in Antarctica, and particularly for subglacial lakes and remote sensing. In this episode, we delve into Martin’s early life in Suffolk, his early career as a road engineer, and learn about the scientific excitement, terrible disappointment, and ongoing lessons from the Subglacial Lake Ellsworth drilling program in East Antarctica.
