Josh Willis

Normally my show notes are carefully reasoned, sober discussions of the remarkable pathways forged by inspirational scientists, and their subsequent breakthroughs. Not this time. This time, I will begin with a headline about today’s Forecast victim guest, Josh Willis, that might be suitable for The Onion:

Idiot leftist scientist thrown out of school, concludes that warm water melts ice

Josh Willis

This is all true, from a certain point of view. Josh was called an idiot leftist scientist by Rush Limbaugh (a moniker enthusiastically adopted by Josh and, err, Josh’s wife), had to leave his PhD program in Physics, and is now leading the massive Oceans Melting Greenland program. But a more realistic telling is doubtless in order.

Josh grew up in Texas and completed a bachelor’s degree in Physics at the University of Houston. There, in the honors program, he met his future wife, a California native. The two soon relocated to SoCal, where Josh entered the PhD program in physics at the University of California San Diego and his wife attended medical school in Los Angeles.

Physics, however, was not to be Josh’s calling and he ultimately did not pass the departmental examinations. Although he came out with a master’s degree in physics, the experience was certainly a setback, and one that took Josh a year or two to get over.

Failure, as is so often the case, had an upside. Rather than inducing a downward spiral, the physics experience ultimately proved a huge relief for Josh, and one that led him to a vastly more fulfilling career studying oceanography at Scripps, where he worked with the great Dean Roemmich. There, Josh did some of the early work on coupling satellite altimetry with ocean observations to estimate ocean heat content.

The start of Josh’s PhD coincided almost exactly with one of the most important advances in oceanography, maybe ever: the Argo program. As Josh says

It was super exciting … it was also kind of scary … In retrospect it seems obvious, but at the time, it was almost crazy

The launch of the incredible Argo data stream created nearly new fields of inquiry, particularly into ocean heat content. But as is the case with any new data explosion, particularly when trying to bolt it onto older datasets, problems can emerge. Josh and his colleagues published a paper entitled “Recent cooling of the upper ocean“, but soon found out that the cooling was due to problems in both the earlier XBT data and software problems in a group of North Atlantic Argo floats. A correction soon followed. I completely view this as a positive, rather than negative, example of how climate science actually functions: scientists follow the data, and revise their conclusions based on new information.

Unfortunately, Josh figured out the error upon walking out the door for a Valentine’s day dinner with his wife. Dinner was a disaster, and

As retribution, my wife had business cards made that have my job title as idiot leftist scientist

Josh’s fake business card, kindly made by Josh’s wife after he botched a Valentine’s day dinner.

Now Josh is pursuing one of the main topics in sea level research: the interactions between Greenland’s marine-terminating glaciers and the surrounding ocean. Prior work had revealed some of these interactions in particular fjords, but Josh and his colleagues are now conducting systematic radar surveys of all of Greenland’s outlet glaciers, combined with sensors parachuted into the fjords. The project — Oceans Melting Greenland — is in the data collection phase, and is part of a recent special issue in Oceanography. Once complete, we should have a much better idea of how and where ice-ocean interactions are strongest, and what the implications will be for sea level rise.

Josh has a wicked sense of humor, even in the face of potential impending disaster for federally-funded climate science. Just check out Dick Dangerfield on the video section of the OMG Facebook page. I like episode 1 in particular.

Restaurants redux

My post on restaurant picks for AGU 2016 was one of the more popular blog entries to date on Forecast, so I thought I’d add a quick podcast on the same topic. I got together with two of my colleagues from Nature Chemical Biology, Mirella Bucci and Grant Miura, to talk through some of my list, and a few new additions. We recorded in the loud, reverb-laden Nature office, so the audio quality is horrendous. And I did virtually none of my usual editing. Quick and dirty, just like a good Mission burrito. Happy eating!

AGU 2016 restaurant recommendations

Due to a flood of requests (ok, one, from Amy Clement) I’m providing an update of my restaurant recommendations for AGU. Last time I mentioned that prices are up. The big update for this year is that prices are up, again, in a big way. Options are terrific, but bring your piggy bank. It can also be extremely hard to get into the more interesting restaurants. So for me, the restaurant scene really epitomizes the Bay Area: yes, you can find great, cheap stuff … but a lot of the really excellent options are far too expensive and crowded. Continue reading →

Laura Wilcox

Inequities exist throughout the scientific enterprise. Women continue to be progressively underrepresented at more senior career stages. Access to excellent research universities is unequally distributed. Representation by many minority groups is low. Nature Geoscience has an entire Focus issue on accessibility, or the lack thereof.

Jon Foley

Jonathan Foley is the Executive Director of the California Academy of Sciences, the previous director of the Institute on the Environment at the University of Minnesota and the founder of the Center for Sustainability and the Global Environment at the University of Wisconsin. In many ways, Jon is one of the foremost thinkers and actors about the science of sustainability. Continue reading →

Bronwyn Wake chief editor of Nature Climate Change

How, exactly, does one get to be an editor of a Nature-branded journal? What do we do? How do we decide what to publish? And what’s up with all our journals? In this episode of Forecast, I hash out these issues with Bronwyn Wake, the chief editor of Nature Climate Change. But don’t worry … if you’re thinking about becoming an editor, working in a bar is not a prerequisite. Continue reading →

Daniel Aldana Cohen on urban climate mitigation

Climate scientists are used to the idea of climate mitigation. But few are involved in the nitty-gritty of what climate mitigation might look like at the local or even neighborhood level. Daniel Aldana Cohen from the Department of Sociology at the University of Pennsylvania is digging into the politics and sociology of urban carbon emissions. A dizzying array of forces are at work. Continue reading →

Amelia Shevenell, big ideas and big risks

Amelia Shevenell from the University of South Florida specializes in big ideas about paleoceanography and the Antarctic Ice Sheet. She’s also keen to push the methodological envelope, which can be risky if things go pear shaped. For Amelia, though, the work resulted in papers in Science (Mg/Ca) and Nature (TEX86). Continue reading →

Scott St. George on tree rings

Tree rings are one of the key tools in paleoclimate research, and might seem like nothing more than big, woody thermometers. But tree-ring science is ever evolving, constantly debated, and — while it has answered some major questions — still grapples with making the connection to broader climate questions.

An update on the 1.5 °C warming threshold

Over the past few months I’ve discussed with a variety of guests the emerging idea of trying to keep global warming below 1.5 °C, and our family of journals has certainly been active on the topic, particularly with regard to feasibility and mitigation pathways.

From Paris Agreement climate proposals need a boost to keep warming well below 2 °C, Nature doi:10.1038/nature18307.
An example of the emissions required to get close to 1.5 (blue), versus unregulated emissions (red). There’s a lot of space in between! From Paris Agreement climate proposals need a boost to keep warming well below 2 °C, Rogelj et al., Nature doi:10.1038/nature18307.
