Bill Boos and I have something in common. Neither of us is much of a long-term planner, but we both like to take advantage of opportunities as they arise. For me, this approach led to a switch from academia to editing. For Bill, it led to an in-process move from Yale to UC Berkeley.

Bill’s career had plenty of twists and turns along the way. Namely, we almost lost him to the dark side … a career in financial consulting at Anderson (now Accenture). Happily, that path didn’t prove sufficiently interesting, and Bill landed in a terminal one-year MS program at MIT, where he started his work with Kerry Emanuel. Except it wasn’t so terminal.
Post-graduation, Bill checked out the professional job market, but quickly found that:
The best job that I’ve interviewed for is not as interesting as staying in graduate school
Things started to click with Kerry, and Bill pursued work on fairly theoretical ocean and atmospheric dynamics. But soon after graduation he published a landmark paper suggesting that a strong Indian monsoon can be generated solely by the presence of the Himalayas: no Tibetan Plateau required. I found the paper fascinating when I handled it at Nature, and it certainly stirred things up in the monsoon community.
As I’ve mentioned on the show in the past, monsoons are endlessly vexing: tantalizing but ephemeral teleconnections; busted predictions; monstrous interannual variability; conceptually simple but terribly complex in the details. One approach to disentangling the mess might be, as Bill puts it, to start off with a clear null-hypothesis:
Can we disprove the hypothesis that this year-to-year variability is just random and we’ll never be able to predict it?
Answering the question would inevitably take a renewed focus on observations, a deep dive into reconstructing past variability, and improved dynamical understanding.
One area of low-hanging fruit — or at least fruit that could be reached by a long extension pole, perhaps while teetering at the top of a rickety three-meter wooden ladder, the base of which has long been under assault by termites — is monsoon depressions. These systems, a topic of much research in the 1970s-1980s, don’t look that horrendous in comparison to typhoons, but end up generating some of the most destructive storms. Why? Bill would like to know. Me too.
Gabe Vecchi is a world-famous atmospheric scientist with a pretty simple attitude to making progress: In order to do something, you need to do it. And Gabe’s done a lot!
He was born in Boston but grew up in Venezuela, and witnessed the country’s dissolution from an intellectual magnet for South America into a dystopian nightmare. Going into the interview, I wondered about Gabe’s perspective on the anti-science, inward-looking trends we’re now seeing in the US. Are we headed for the same fate?
At this point, it’s impossible to say. But what I can say is that Gabe’s enthusiasm for science is undiminished by current politics. It was, in fact, kind of refreshing to talk to someone outside of the Bay Area echo chamber in which I live. It’s good to see science (and home renovations and new jobs) remaining at the forefront.
Gabe’s grandparents immigrated to Venezuela from Italy, and he lived there until his early teens. Ending up as a scientists might have been inevitable:
I think having [an] engineer and artist [as parents] … the only natural outcome is to be a scientist
And even though Gabe began knowing, as he says, just about nothing, he went on to make some of the major advances in atmospheric dynamics, tropical cyclones and seasonal prediction over the past couple of decades, including the now-famous modeling of a reduced zonal circulation in the equatorial Pacific.
Working in the Geophysical Fluid Dynamics Laboratory, with brilliant colleagues like Isaac Held and Suki Manabe, played a part in Gabe’s success. But still, and as so often seems to be the case, some of the big findings arose almost by accident.
By working on the still-not-fully-cracked nut of estimating changes in hurricane frequency and intensity in a warming climate, Gabe and his colleagues ended up with a modeling system with seasonal skill in regional hurricane prediction. The field is now able to resolve the small scale interactions between hurricanes and the large scale environment. Probably, as Gabe says, they wouldn’t have gotten to seasonal hurricane prediction if they’d been trying to do so:
You can’t see things if you look at them directly
As always with forecasting/prediction, it is easy to get carried away. But Gabe has a healthy skepticism for all sorts of modeling, prediction included:
Skill when applied to the past tends to be higher than skill going forward
Most importantly, one should keep a careful eye out for wild-eyed optimism or irrational exuberance:
The better you feel about it the worse it behaves … the probability of misleading yourself can be very high
Now in a multi-disciplinary department at Princeton, Gabe is looking both forwards and backwards. Forwards, to a closer collaboration with the geochemical proxy community, to unravel some of the many competing hypotheses for modern processes. Backwards, to hopefully develop a state-of-the-art yet simple climate model that could be run in a desktop machine by any interested academic, rather than at a super-computing facility.
Either way, there is endless scope for peeking under the mossy rocks of science, or looking for the structural members that we still need to install:
The things that we already know are much less interesting … if I can find something that we don’t know or that is kind of broken, then that’s great
Today’s music is from the album Anthropomorphic by Sister Sadie’s Foundry. Vocals and acoustic guitar are by geochemist Mark Pagani, who passed away in November 2016. I knew Mark just a little bit, but enough to know that he had a raging passion for science and life. At the time, I didn’t know about his wild musical chops, but they’re impressive for sure. In some ways, Gabe reminds me of Mark, and I thought the music would be a great match for today’s interview. Clips are used with the kind permission of Teresa Pagani and Michael Powers. Songs are Coming up for Air, Dry Land, and Skull and Bones. I encourage you to check out the album — it’s great!
Today’s interview, with Jory Lerback from the University of Utah, has both nothing and everything to do with climate science. I think for the first time in the history of Forecast, no one mentioned the word climate. Instead, we talked about Jory’s recent Nature Comment entitled “Journals invite too few women to referee“.

Jory’s work arose out of her time between undergraduate and graduate studies, when she worked at AGU headquarters analyzing their massive database of authors and referees.
There is some good news on the gender equity front. For the youngest cohorts of geosciences, women are at ~ 40% of corresponding authors.
But otherwise, it’s still discouraging. Overall, women are about 28% of AGU authors, yet make up only 20% of the pool of referees. So, even relative to their low representation as authors, women are even more underrepresented as referees.
The problem arises at least in part because corresponding authors recommend too few women and editors select too few women. Women also decline reviews at slightly higher rates.
At Nature, our informal analysis shows roughly similar results, although in some fields, submitting authors recommend women referees in the single digit range.
Addressing gender inequity in science is a perpetual topic, but for the specific case of referees, there is at least a practical way forward. Authors — recommend female referees! Editors — invite female referees … and when invited referees decline, ask for recommendations for appropriate female alternatives.
Alternative facts are much in the news. The idea is, of course, ridiculous. Some things are clearly facts. Pizza is delicious; cake makes me happy; serving a white Burgundy at 40 F is an abomination; you should never wear a backpack with a suit.
Much of climate science, however, is not what you would call a hard fact. Yes, we can begin with some facts, following immediately with a suite of questions on quantification and mechanism. Yes, the Greenland Ice Sheet is losing mass. But what is driving the variations in time and space, are there physical limitations to retreat rates, what are the constraints on ice sheets behavior from paleoclimate, what is the role of firn/cryoconite/black carbon?
Research moves to the open questions, which, to some, provides an opening to say that scientists don’t have the facts. For the immediate questions at hand, it is of course true that we don’t have the answers — that’s why there’s research! Let’s not lose track of the vast amount of knowledge, and the big picture facts, that we do have.
Rant over, at least for now!
Sometimes I don’t fully grasp the scope of what Forecast guests are doing until I have time to reflect, during editing or while writing the show notes. That was certainly the case with today’s guest, Nerilie Abram. Nerilie has astonishingly broad interests. She works with corals, ice cores, speleothems, and modelers on topics all over the world (literally!) from the past to the future.
Much of our discussion centered around the process by which Nerilie cracks open new topics: framing questions, conducting research, challenging her own ideas, and grinding through the review process. Over time, this is the work that ends up in the fact category. It takes, in addition to mad technique, stubbornness:
Science requires, for all sorts of reasons, people who are going to be able to stick it out in this game, to have that kind of determination … not just the skills
Facts are indeed hard to come by, and proxies can be particularly bedeviling, particularly if one takes the time to actually think about them:
When you’re dealing with indirect proxies, things can change that you’re not expecting
All of which makes me think of Nerilie as the Danny Meyer of science. What, you’re running a restaurant in a museum now? Or in Nerilie’s case, what, you had a quick talk with Nick Shackleton and now you’re off to the British Antarctic Survey? Smashing!

And the field work. Oh yes, the field work. Plenty of people get into geosciences for the amazing field sites. Nerilie never said that she’s in it for the travel, but it couldn’t have hurt.
I like doing Forecast for a lot of reasons. I get my fingers into the entrails of science in a way that isn’t really possible from reading submissions. I hear some appalling stories, off the record. I’m caught up in the enthusiasm of scientists for what they’re dreaming of discovering in the next decade. But, maybe most of all, I get to ask all kinds of impertinent questions that would rouse the ghost of John Maddox if done during the course of normal editor-scientist interactions.
And so it is with my interview with Noah Diffenbaugh, one of the leading investigators of extreme events in a changing climate, and a friend for over 10 years. Getting to know someone in science, especially after grad school, is weird, as huge chunks of their being remain out of view. Indeed I am often reminded of the blind men and an elephant. Perhaps before I only saw Noah’s enormous feet and extravagant tail, without realizing his true self. I am not at all sure that I do now, but at least it is clear he is a pachyderm.
Noah grew up at the Mount Madonna Center, one of the intentional communities that erupted like mushrooms from the rains of the 1960s’ spiritual and yoga movements. Most withered under divisiveness, absolutism, and isolationism. Mount Madonna, though, continues to thrive. Yes, it was, and is, a yoga and communal life center. But it is not a cult. Instead, it is open to the outside world, and has grown to support a renowned school and series of cultural events.
Mount Madonna’s sense of openness and inquiry are a clear feature of Noah’s work and collaborations. Our work together, on topics like wine and climate, grew from a short chat in an elevator during an NCAR young scientist boot camp. In general, because it’s impossible to tell which collaborations are going to work out, Noah’s default is yes.
Saying yes has clearly worked for Noah. He spent time at Purdue and is now tenured at Stanford, one of the premier universities in the world (and a very tough place to get tenure). Noah’s involved in the IPCC, regularly consults with a huge range of public and private interests, and publishes in Science and Nature. The path to the top was clear, and swift.
Except, no. Noah was an undergrad premed at Stanford. Until he failed, spectacularly, Chem 31. Then it was, almost, a degree in religious studies. But, no. Earth Systems 10 proved riveting and, fortunately for the field (and my own academic career!), Noah turned to science.
At least for a while. Upon graduation, Noah returned to Mount Madonna. He taught at the center’s school but a broader direction eluded; restlessness grew; the benefits and costs of communal life came into sharper focus.
I essentially didn’t go through adolescence and didn’t really leave home until my mid 20s when I was already married and already had a kid
For a lot of us, grad school attracts because it is something to do that seems potentially valuable, interesting and fun, without having to make an absolute choice about what, exactly, you’re committing to. So it was for Noah.
I went to grad school, and I made my grad school decision, for all the wrong reasons … if I ever said out loud my motivation and what I was thinking … I don’t think I would ever get admitted
And leaving home, surprisingly, only meant moving a few miles from Mount Madonna to UC Santa Cruz. Noah eventually settled on paleoclimate research with Lisa Sloan, but only after considering other — and wildly unrelated — options.
Since then, I think the path has been clearer, and Noah has made major contributions to our understanding of extreme heat, among many other topics. Most of our conversation, however, had a decidedly philosophical bent to it, and we wrapped up with a discussion of how the US presidential election at least had the useful outcome of prompting Noah to think about how scientists communicate statistics.
We talked for almost two hours, and still did not get to a lot of topics I wanted to cover (being the chief editor for GRL, life as an academic in Silicon Valley, gender balance in science, non-governmental funding). Editing the interview down to something reasonable took me forever, but I wanted to keep as much as possible. I think the story of Noah’s path through life and science could prove useful, especially for young scientists starting out and wondering if any of your role models also wondered … what am I doing in grad school, why did I pick this advisor, why am I studying this topic, am I really this bad at lab work. Yes. Yes they did. You too might come out the other side.
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
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
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.
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!
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 →
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.
