Max Moritz regales Mike with some of the many intricacies of modern fire science. The dominant narrative in the Western US might be “long-term fire suppression is leading to severe fire seasons”. While there is some truth here, the individual fire stories are, inevitably, local. Local land use practices, building codes, vegetation stress, and climate […]

Numerical weather prediction (NWP) is like excellent coffee in the Bay Area: so common that it is now taken for granted, obscuring the decades of expertise, knowledge, and technique underlying the whole operation. In episode 77 of Forecast, Peter Bauer from the European Centre for Medium-range Weather Forecasts tells Mike about the massive and decades-long […]

Steve Running from the University of Montana helped to invent the field of large-area, quantitative ecology. Steve was also my MS and PhD advisor – a role that doubtless was the most fulfilling of his career. This August, Steve celebrates his retirement with a reunion of lab members and close colleagues — a reunion that […]

Yao Tandong tells Mike about realizing his long-held dream: working of the Tibetan Plateau, now as director of the Institute for Tibetan Plateau (ITP) Research (and much else besides!). For Tandong, it all began in 1978 when he was initially exposed to Tibetan glaciology. It cannot have been an easy path. Tandong’s parents were minimally […]

The land biosphere takes up a big chunk of atmospheric CO2 emissions. But how, where, and for how long remains an area of, ahem, active research. Or put another way, there’s a lot we STILL don’t know about how increased CO2 will manifest, or not, as an ongoing increase in the terrestrial uptake of carbon. […]

Sergey Gulev from Moscow State University grew up in the Soviet Union, forged a career as an oceanographer, and then witnessed the dissolution of much of what he and his colleagues had built. Gone were their four ocean-going ships, and the then-Russian science community was not able to capitalize on the modeling and remote sensing […]

Carl Wunsch is at the heart of many of the major advances in modern physical oceanography. The World Ocean Circulation Experiment, satellite altimetry, acoustic tomography, and Estimating the Circulation and Climate of the Ocean: all are hard to imagine without Carl’s involvement. In this extended interview, Carl tells Mike about these and many other aspects […]

Carolina Vera from the University of Buenos Aires tells Mike about her work on the South American monsoon. Relative to the Indian and Asian Monsoon, the South American Monsoon is understudied — but equally fascinating. The bulk of the land mass is centered near the equator, amplifying the role of tropical ocean-atmosphere interactions. The Andes […]

Sarah Kang from the Ulsan National Institute of Science and Technology tells Mike about her work to understand the atmospheric and oceanic dynamics that link the extratropics to the tropics. Paleoclimate research has long shown that climate perturbations with strong Northern Hemisphere imprints — like Dansgaard-Oeschger events — are associated with movements of the Intertropical […]

Jay Famiglietti from NASA’s Jet Propulsion Laboratory tells Mike about taking the plunge into using the GRACE gravity-measuring satellites for hydrology research. Keep in mind, this was at a time when hydrology was viewed as noise in the gravity signal, and that Jay was just starting off as an academic with his first graduate student, […]

Maisa Rojas from the University of Chile tells Mike about her work on regional climate modeling, paleoclimate, and the Southern Hemisphere westerlies. The story begins with Maisa’s birth in Chile, but quickly moves on to the family’s dramatic escape from Pinochet’s rebellion and immigration to Germany. Maisa returned to Chile at age 12, and then […]

World-famous economist Michael Greenstone tells Mike about his main professional mission: to apply the tools of economics to reduce human suffering. But that wasn’t always the case. No indeed. For many years, including all of college, Michael’s main goal in life was to have a career in the NBA. Happily for economics, Division III basketball […]

Kaitlin Naughten from the University of New South Wales works on one of the most pressing issues facing modern climate science: interactions between the ocean and the vast ice shelves fringing Antarctica. Existentially, this interaction has the potential to largely determine the rate and amount of sea level rise disgorging from the continent. Will it […]

I met Sonia Seneviratne from ETH Zürich at a climate conference way back in 2013. This was not long after she served as a coordinating lead author of the now-famous IPCC SREX report, which lit a spark under the field of climate extremes. Sonia tells me the back story of becoming a CLA, the ongoing […]

Speleothems — stalagmites, stalactites, flowstones — are a central tool for reconstructing past hydroclimate variability. But what, really, are they recording? Jessica Oster from Vanderbilt University walks Mike through the long, incredibly long, process of permitting, extracting, transporting, sampling, analyzing, and understanding the isotopic signals encoded in these bedeviling but transporting recorders. Succeeding in the […]

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 […]

There’s incessant talk about impostor syndrome among scientists. But paleoclimate modeler Dan Lunt from the University of Bristol actually DOES pretend to be someone he is not. Specifically, Radagast the Brown from Tolkien’s Middle Earth and Samwell Tarly from Martin’s Westeros. Madness? Only if it is mad to spend what must have been a ridiculous amount […]

Andrea Dutton from the University of Florida tells Mike about the many nuances of using corals to reconstruct past sea level. Sounds simple enough: find corals at depth z, date them to year t, and Bob’s your uncle. Yeah … no. Turns out there’s a lot more at play: 3D topography, plasticity in coral’s depth […]

Abby Swann tells Mike how plants both respond to and affect climate change. Some of this seems obvious: more CO2, more photosynthesis, bigger plants. Maybe, but there’s a lot more to it: nutrient limitations (or lack thereof!), changes in respiration, stomatal conductance downregulation, drought responses, sea ice interactions, atmospheric feedbacks, changes in land cover … […]

In episode 58 of Forecast, Mike talks with Henri Drake, Jennifer Carman, and Molly Keogh, three of the attendees at the 11th Graduate Climate Conference. The meeting itself is a great chance for grad students working on climate change — broadly defined — to get together with their immediate peers, away from, ahem, pesky senior scientists. […]

Tom Narock and Chris Jackson tell Mike about the new EarthArXiv preprint server.  The show is a bit of an oddball for Forecast, considering that the show’s usual diet is long-format interviews about a scientist’s life and research. But the launch of EarthArXiv — one of a growing series of preprint servers — could be […]

Deciphering the global carbon cycle is as fascinating as it is difficult. There are carbon fluxes in and out of the planet, all over the place, and at all time scales. Observational gaps are numerous and gaping. Uncertainties on country level emissions are increasing. Yet the global carbon budget is perhaps THE central bit of […]

Most everyone you’ve heard on Forecast has a twisty career path. But Joe McConnell took an unusually circuitous route to his current role as a leading ice core scientist. Joe bombed as a dishwasher, thrived as a post-hole digger, started a consulting company as a teenager, considered anthropology and environmental law for his studies, switched […]

In Episode 54 of Forecast, Peter Cox from the University of Exeter gives Mike the inside story about how the “emergent constraints” approach is reshaping our ability to wring every last drop of useful information from climate models. It’s a two step process. First, using climate models, establish a relationship between something you care about […]
