Spending Christmas With “Dr. Doom”

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration.

I was 11 years old the year my older stepsister brought her high school boyfriend home for the first time. It was Thanksgiving 2006, and his Southern manners fit right in as we bantered between mouthfuls of cornbread stuffing, fried okra, and marshmallow-topped sweet potato casserole. Then, in the overstuffed lull before the desserts were served, my dad plunked his laptop in the center of the table. He opened it up and began clicking through a PowerPoint presentation chock full of data on ice sheet melt and global atmospheric carbon dioxide concentration. 

My stepsister’s eyes grew wide with embarrassment. In an effort to welcome her sweetheart to the family, my dad had rolled out his version of a red carpet: one of his many family lectures on the horrors of climate change. 

This wasn’t the first—or last—time my dad’s climate obsession took center stage at our family gatherings. On that particular occasion, he was doling out factoids about Arctic amplification—the prevalence of which was then a debate among climate scientists. It was just a warm-up to a typical holiday season spent quibbling over the ethics of farmed Christmas trees and openly scoffing at scientific inaccuracies during a movie theater showing of Happy Feet, the year’s seasonal offering about a dancing penguin named Mumble. A month later, on Christmas Eve, he forwarded me an email about how Santa Claus’ body would disintegrate if he were to travel through the atmosphere at the speeds necessary to meet his seasonal duties, adding a personal note: “Not to mention the emissions!”

Over the years, these tendencies earned him the family nickname “Dr. Doom”—a nod to his university professor title and compulsive need to share terrifying facts about our warming world. My dad hammed it up, interrupting his own lamentations by hooting out, “We’re all gonna die!” in a cartoonish falsetto. More than anything, it was a term of endearment. After all, we knew other households that spent their holidays arguing over whether climate change was even real.

Many of us know a Dr. Doom in our lives, or at the very least, a pessimist with a particular fixation. We each have our own ways of responding to it, such as my brother’s pragmatism, my stepmom’s knee-jerk optimism, my stepsister’s exasperation. Or, perhaps you are the doomer yourself. 

I’m usually tempted to respond with, “I see hope in the next generation.” But doomerism—a label often used to describe climate defeatists—doesn’t typically leave room to talk about a better future. It’s a contagious kind of despair, often too credible to dismiss. Nowadays, my brother and I both work in climate-related fields, undeniably thanks to Dr. Doom’s influence. But growing up, it only took a few days of dad’s soapboxing before I’d tune out of anything climate-related until the New Year.

This Christmas, as we once again prepare to pass around the cranberry sauce and discuss the end of the world, I can’t help but wonder how my dad became Dr. Doom. And in a world of rising doomerism, what influence do such tidings have on others?

My dad’s journey to becoming “Dr. Doom” started with his formal training as a tropical ecologist. Until the early 2000s, his work meant trudging through rainforests, studying photosynthesis while battling mosquitoes. Then, the wear of human activity on his surroundings became too much to bear. He switched gears and has since spent his career leap-frogging between climate education jobs—from director of an environmental science program at the University of Idaho to president of a small school in Maine, which, in 2012, he led to become the first college to divest fully from fossil fuels.

Those entrenched in science, like my dad, seem to be especially susceptible to climate despair. That’s according to experts like Rebecca Weston, the co-executive director of the Climate Psychology Alliance of North America, a community of mental health professionals trained to address the emotional and psychological challenges emerging in our warming world. Many in scientific fields, Weston says, are first to document and review the data behind irreversible loss.

The facts of the crisis are so dire that despair seems to be a hazard for many—scientists or not. After all, a study by researchers at the Yale Program on Climate Change Communication found that some 7 percent of US adults report potentially serious levels of psychological distress about climate change. Gale Sinatra, a professor of psychology at the University of Southern California’s Rossier School of Education who studies how people learn about climate change, put it more simply: “Your dad’s problem is that he knows too much.”

The issue only gets worse when the climate-informed try to share what they know. In a short-lived position in 2007 as science advisor to the Florida state government (back when then-Governor Charlie Crist would actually acknowledge “climate change”) my dad was silenced during a presentation to the legislature. A report later said that the “awkward” situation arose when a Republican senator took issue with a discussion topic that “had not yet been accepted as fact.” According to my dad, the controversy stemmed from his decision to share the famous “hockey stick” graph, a data visual that shows that global average temperatures began spiking after human societies industrialized.  

“We’re starting to understand it as moral injury,” said Kristan Childs, co-chair of a committee to support climate scientists with the Climate Psychology Alliance, referring to a psychological phenomenon that happens when people witness actions that violate their beliefs or damage their conscience. “They’ve been informing people for so long, and there’s just such a betrayal because people are not believing them, or are not doing enough to act on it.”

Like many, my dad’s response to this was to get louder—and darker. There’s conflicting research on how different kinds of messaging can affect people’s behavior. Some studies show that those experiencing distress are also more active, while others say that emphasizing worst-case scenarios, like so-called climate “tipping points,” is an ineffective strategy that can overwhelm and de-motivate audiences instead. It can also backfire on a personal level: Listeners of the podcast “This American Life” may be familiar with a story about a climate activist dad whose zeal led to his children cutting him out of their lives

As a journalist on the climate beat, I’ve interviewed dozens of self-described “doomers,” and yet I’ve found the term is a bit of a misnomer. While many fixate on the worst possible climate scenarios, they’re generally not quitters. As Childs put it, “I don’t know anyone who’s just given up on it all.” Instead, nearly all have dedicated their lives to addressing climate change. And they can’t help but evangelize, warning everybody within earshot of the ways the coming century could change their lives. 

Throughout these interviews, I’m tacitly looking for any insight that might help my own Dr. Doom. (Recently, I accompanied my dad to a physical therapy appointment where, upon seeing a disposable blood pressure cuff, he attempted to regale his doctor with facts about the greenhouse gas emissions associated with the US health care system.) Childs might just have some. She offers a 10-step program for professionals who work in science-oriented fields, affiliated with a larger collection of support groups offered by the Good Grief Network, a nonprofit organization dedicated to processing emotions on climate change. 

“The group work is powerful because it really, really helps dissolve the sense of isolation,” Childs said. As she spoke, I shifted uncomfortably, wondering how many times my teenage tendency to tune out or respond flippantly made my dad feel I was invalidating his concerns.

The best place to start is often the hardest: acknowledging how bad the problem is. “It’s actually helpful to give people a place to share their biggest fears,” she said, adding that the typical workplace culture in scientific fields discourages expressing emotions. “Somehow some acceptance of how bad it is, and the fact that we can then still stay engaged, shifts the question to who we can be in these times.”  

Weston agrees that entirely erasing climate anxiety isn’t realistic, especially as the effects of Earth’s changing atmosphere become more apparent and frightening. Instead, her group suggests reframing ideas of what having a meaningful impact looks like. “It depends on breaking through a kind of individualist understanding of achievement. It’s about facing something that will be resolved past our own lifetimes,” she said.

My dad has spent his career chasing that elusive sense of fulfillment—never quite satisfied with the work he’s doing. But lately, he’s found a reason to stay put. In 2019, he returned to my hometown to teach climate change to undergraduates at the University of Florida. Now and again, I’ve wondered how these 18- to 22-year-olds, many of whom grew up in the increasingly red state, respond to his doomsaying.

This year, while home around Thanksgiving, I sat in on his last lecture of the semester—a doozy on how economic systems can destroy natural resources. His students seemed completely at ease—chatting with him at the beginning of class, easily participating when he asked questions. I was already surprised.

“He’s just sharing the facts,” one of his students told me, when I asked a group of them about his teaching style after the class. 

Another quickly interjected: “He’s too dogmatic. It’s super depressing, it’s super doom.” Others nodded. 

A third chimed in: “It helps me feel motivated.” 

Later that week, while I was reporting a different story at a local climate event, both his former students and local activists flagged me down to say how much they appreciated my dad’s courses and op-eds in local newspapers. 

“We need all sorts of climate communication. People are responsive to different messages,” said Ayana Elizabeth Johnson, the markedly anti-doomer author of What If We Get It Right?, a recent book that puts possibility at the center of climate action. In 2019, a Yale study on how people respond to different messaging tactics underscored this point—finding that “hope is not always good, and doubt is not always bad.”

For Johnson, getting through the climate crisis starts with who you surround yourself with. “This is not solitary work. Individual changemakers are not really a thing,” she said. “We never know the ripples that we’re going to have.”

The Christmas stockings on the mantle at my dad’s house haven’t changed in years, but the dinner conversations have. Now, instead of trying to brush aside Dr. Doom’s digressions, we lean in. Our evenings are spent butting heads over the recent climate optimism book, Not the End of the World, by data scientist Hannah Ritchie; swapping notes on heat pumps; and debating how to make the most of used-EV tax credits. My baby nephew, Auggie, of the latest generation to be saddled with our hopes and fears, brightens the room with his cooing at all manner of round fruits and toy trucks. 

Between sips from warm mugs, my dad leans back in his chair and frowns at some news on his phone’s screen. “The wheels are really coming off the wagon, kids. Humanity faces an existential threat,” he says, to no one in particular. From the next room, my stepmom calls, “The sky’s been falling since I met you, Stephen.”

It’s hard not to smile. Who knows how many people my dad has influenced, or if he will ever feel satisfied with his mission. But as his doomy, gloomy self, he’s built a community and family that share his values. At that moment, I find myself thinking of something Childs told me: “You cannot protect your kids from climate change. But you can protect them from being alone with climate change.” 

In our changing world, these conversations feel like something to be thankful for. 

A Cool New Ally in the Fight to Reduce Atmospheric Carbon: Chonkus

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration.

Tucked away in the most extreme nooks and crannies of the Earth are biodiverse galaxies of microorganisms—some that might help scour the atmosphere of the carbon dioxide mankind has pumped into it.

One microorganism in particular has captured scientists’ attention. UTEX 3222, nicknamed “Chonkus” for the way it guzzles carbon dioxide, is a previously unknown cyanobacterium found in volcanic ocean vents. A recent paper in the journal Applied and Environmental Microbiology found it boasts exceptional atmosphere-cleaning potential—even among its well-studied peers. If scientists can figure out how to genetically engineer it, this single-celled organism’s natural quirks could become supercharged into a low-waste carbon capture system.

Cyanobacteria like Chonkus, sometimes referred to by the misnomer blue-green algae, are aquatic organisms that, suck up light and carbon dioxide and turn it into food, photosynthesizing like plants. But tucked away inside their single-celled bodies are compartments that allow them to concentrate and gobble up more CO2 than their distant leafy relatives. When found in exotic environments, they can evolve unique characteristics not often found in nature. For microorganism researchers, whose field has long revolved around a handful of easy-to-manage organisms like yeast and E. coli, the untapped biodiversity heralds new possibilities.

“There’s no question we’ll keep finding really, really interesting biology in these vents. I can’t stress enough that this was just the first expedition.”

“There’s more and more excitement about isolating new organisms,” said Braden Tierney, a microbiologist and one of the lead authors of the paper that identified Chonkus. On an expedition in September 2022, Tierney and researchers from the University of Palermo in Italy dove into the waters surrounding Vulcano, an island off the coast of Sicily where volcanic vents in shallow waters provide an unusual habitat—illuminated by sunlight and yet rich with plumes of carbon-dioxide. The location yielded a veritable soup of microbial life, including Chonkus.

After Tierney retrieved flasks of the seawater, Max Schubert, the other lead author of the cyanobacteria paper and a lead project scientist at the scientific nonprofit Align to Innovate, got to work identifying the different organisms in it. Schubert said that out in the open ocean, cyanobacteria like Chonkus grow slowly and are thinly dispersed. “But if we wanted to use them to pull down carbon dioxide, we would want to grow them a lot faster,” he said, “and grow in concentrations that don’t exist in the open ocean.”

Back in the lab, Chonkus did just that—growing faster and thicker than other previously discovered cyanobacteria candidates for carbon capture systems. “When you grow a culture of bacteria, it looks like broth and the bacteria are very dilute in the culture,” Schubert said, “but we found that Chonkus would settle into this stuff that is much more dense, like a green peanut butter.”

Chonkus’ peanut butter consistency is important for the strain’s potential in green biotechnologies. Typically, biotech industries that use cyanobacteria and algae need to separate them from the water they grow in. Because Chonkus does so naturally with gravity, Schubert says, it could make the process more efficient. But there are plenty of other puzzles to solve before a discovery like Chonkus can be used for carbon capture.

CyanoCapture, a cyanobacteria carbon capture startup based in the United Kingdom, has developed a low-cost method of catching carbon dioxide that runs on biomass, housing algae and cyanobacteria in clear tubes where they can grow and filter CO2. Although Chonkus shows unique promise, David Kim, the company’s CEO and founder, said biotechnology companies need to have more control over its traits, like carbon storage, to use it successfully, and that requires finding a way to crack open its DNA.

“Oftentimes we’ll find in nature that a microbe can do something kind of cool, but it doesn’t do it as well as we need to,” said Henry Lee, CEO of Cultivarium, a nonprofit biotech startup in Watertown, Massachusetts, that specializes in genetically engineering microbes. Cultivarium has been working with CyanoCapture to help them study Chonkus but has yet to figure out how to tinker with its DNA and improve its carbon capturing attributes. “Everybody wants to juice it up and tweak it,” he said.

Since the expedition to Vulcano where Tierney scooped up Chonkus, the nonprofit he founded to explore more extreme environments around the world, the Two Frontiers Project, has also sampled hot springs in Colorado, volcanic chimneys in the Tyrrhenian Sea near Italy, and coral reefs in the Red Sea. Perhaps out there, researchers will find a chunkier Chonkus that can pack away even more carbon, microbes that can help regrow corals, or more organisms that can ease the pains of a rapidly warming world. “There’s no question we’ll keep finding really, really interesting biology in these vents,” Tierney said. “I can’t stress enough that this was just the first expedition.”

Kim noted that out of all the microbes out there, less than 0.01 percent have been studied. “They don’t represent the true arsenal of microbes that we could potentially work with to achieve humanity’s goals.”
