His intellectual influences include longtime climate action skeptics — and Bill Gates’ favorite author.

Donald Trump’s nominee for Secretary of Energy, Chris Wright, is a nerd — and he’ll tell you about it. “I’m Chris Wright, and my short bio is, I started out as a science geek, I transitioned to a tech nerd, and then I’ve been an energy entrepreneur my whole life,” he told energy journalist Robert Bryce on the Power Hungry podcast in 2020. “In addition to an energy nerd, I’ve been a climate nerd for quite some time,” he said in a talk hosted by Veriten, the energy consulting firm in 2023.
This is a far cry from Trump’s first Energy Secretary, the former Texas Governor Rick Perry, who famously failed to remember on the Republican primary debate stage the third of the three agencies he sought to eliminate (it was the Department of Energy) and who reportedly didn’t know that the Energy Department’s responsibilities — and budget — then lay heavily with maintaining the country’s nuclear stockpile.
But Wright’s extensive energy experience — studying nuclear fusion at the Massachusetts Institute of Technology and working early in his career on solar and geothermal engineering (his company, Liberty Energy, the fracking powerhouse he founded in 2011, has invested in the next-generation geothermal company Fervo, and Wright sits on the board of the nuclear company Oklo) — has not won him any plaudits from environmental groups or Democrats who focus on climate change. After Trump announced his nomination, the Sierra Club called Wright a “climate denier who has profited off of polluting our communities and endangering our health and future.” Illinois Rep. Sean Casten, one of the House’s most vocal proponents of climate action, also called Wright a “climate denier who prioritizes the wants of energy producers over the needs of American consumers.”
Few Republicans — and certainly few high-level Trump appointees — are as conversant in climate and energy data as Wright. That may make him an even more effective advocate for Trump’s “energy dominance” strategy, built around increased production of fossil fuels and, almost certainly, fewer subsidies for clean energy and electrification.
Typically when a person gains some notoriety by coming out against immediate, large-scale climate action and restrictions on fossil fuel extraction, climate advocates try to link that person to the fossil fuel industry and its long history of deliberate and knowing climate denial. Wright’s associations, however, are perfectly straightforward: Liberty Energy fracks oil and gas in the United States and Canada on behalf of large oil companies. He thinks the company’s contribution to the good of the world consists of its producing more hydrocarbons — full stop.

Wright calls this philosophy “energy sobriety,” fully conceding that climate change is real while also diminishing the urgency of mounting a response. In seemingly countless speeches, interviews, and legislative testimonies, as well as in Liberty Energy’s annual “Bettering Human Lives” report — its version of an environmental, social, and governance review — Wright is perfectly comfortable acknowledging climate change while also patiently assaulting many key pillars of climate policy as it’s practiced in the United States, Europe, and other countries in the developed world seeking to sharply reduce greenhouse gas emissions.
While Wright’s written and spoken record adds up to tens of thousands of words and hours of talks, it can be distilled into a few core ideas: Energy consumption makes people better off; energy access, especially in the developing world, is a greater global challenge than climate change; and existing alternatives to hydrocarbons are not capable of replacing the status quo energy system, which still overwhelmingly relies on fossil fuels, with little prospect of a rapid transition.
He cites a wide range of thinkers, including members of a group of scholars — including the Danish political scientist Bjorn Lomborg (whose book, False Alarm, is “fantastic,” Wright said in a Liberty talk), University of Colorado science policy scholar Roger Pielke, Jr. (“a real intellectual”), and the Canadian energy scholar and historian Vaclav Smil (“the greatest energy scholar of my lifetime by far”) — who share elements of this deflationary view of climate change.
Lomborg and Pielke have long been bêtes noires of the climate movement, mostly as the subjects of years of furious back and forth in every form of media for the past two-plus decades. (Though in Pielke’s case, there was also an investigation in 2015 over alleged conflicts of interest led by House Democrat Raul Grijalva, who is retiring from Congress this year.) Lomborg has for decades argued that climate change ranks relatively low on global challenges compared to, say, global public health, while Pielke contends that many climate change policy advocates overstate what the Intergovernmental Panel on Climate Change actually says about the connection between climate change and extreme weather, a point that has made him the object of intense criticism for going on 15 years.
Smil, meanwhile, is deeply skeptical of any effort to wean the world from fossil fuels considering their role in the production of steel, cement, plastics, and fertilizers — the materials that he describes as essential to the modern world. Smil also counts among his fans Bill Gates (“Vaclav Smil is my favorite author”), who is also one of the biggest funders and promoters of climate action through his research and investment group Breakthrough Energy and funding for companies like TerraPower, which is currently building the country’s first next-generation nuclear facility in Wyoming.
Pielke called both Wright and Doug Burgum, Trump’s nominee for Secretary of the Interior and the designated head of a planned National Energy Council “super competent. They know energy, and that’s a fantastic starting point,” he told me.
“There is polarization of the climate debate, and the idea that fossil fuels are evil and the fossil industry are arch-villains — that’s part of the framing from the progressive left about how climate wars are to be fought,” Pielke said. “I’m not particularly wedded to that sort of Manichean evil vs. good framing of the debate.”
But the differences are real. Wright strongly contests much of what is the mainstream of climate policy. While he acknowledges that increased concentrations of carbon dioxide cause higher temperature, he says it’s “actually sort of slow-moving in our lifetimes” and a “relatively modest phenomenon that’s just been wildly abused for political reasons,” he said in a talk to the conservative policy group American Legislative Exchange Council.
While the Department of Energy has only limited authority over energy policy, per se, especially the permitting and public lands issues that typically concern fossil fuel companies, Wright does have some levers he can pull. He will likely act quickly to approve more export facilities for liquified natural gas, though the Energy Department’s recently released study of LNG’s long-term effects — particularly on domestic energy prices — may complicate that somewhat. Beyond that, he will inherit a massive energy research portfolio through the national labs, putting him in charge of developing the energy technology that he says are currently insufficient to replace oil and gas.
“I’ve worked on alternatives. I’d love it if fusion energy arrives,” Wright said in an interview with the conservative website Power Line. “I love energy technology, and I think there’s good things going on, but it’s now become political.”
He believes that reaching net zero greenhouse gas emissions by 2050 is “neither achievable nor humane,” he wrote in the foreword to the 2024 edition of “Bettering Human Lives.” He also disagrees with the idea of subsidizing the world’s predominant forms of alternative energy, solar and wind.
“Wind and solar are never going to be dominant sources of energy in the world,” Wright told Bryce on the 2020 podcast. The “main impact” of subsidies for wind and solar, Wright said in another 2023 podcast episode with Bryce, “is just to make our electricity grids less reliable and electricity prices more expensive, and to do nothing for the demand for oil and very little for the demand for natural gas.”
“Oil and gas make the world go round,” he added. “[People] want higher quality of lives. That’s what drives the demand for oil and gas.”
Bryce, a persistent critic of green energy policies, told me in an email that he thinks Wright is “the right person for the DOE. He’s not apologetic about being an energy humanist. Regardless of what anyone thinks about climate change, it is obvious that we are going to need a lot more energy in the future, and the majority of that new supply will come from hydrocarbons.”
While Wright’s arguments certainly have wide purchase among his peers in the energy industry executive corps, he nevertheless stands out from the rest for his willingness to express them. In contrast to the stance taken by large, multinational energy companies, which are willing at least to pay lip service to carbon reduction goals and have, at times, embraced branding and marketing strategies to make them seem like something other than oil and gas companies (e.g. ExxonMobil’s algae-based fuel initiative and BP’s notorious “Beyond Petroleum” campaign), Wright and his company see their contribution to a better world as their work extracting oil and gas.
Other executives “don’t want to deal with the criticism that will come with taking a higher-profile stance,” Bryce told me. “They don’t have time or the inclination. It takes a lot of time, courage, and conviction to engage with the media, get on the speaking circuit, and do so in a thoughtful way.”
Wright’s emphasis on the energy poverty faced by poor countries could potentially serve as a diplomatic bridge to the developing world, especially in Africa, where some observers think there’s space for the United States to start funding natural gas development through the International Development Finance Corporation. For Wright, expanding energy production — and specifically fossil fuel development — is crucial to providing cheap energy to the developing world. He mentions in almost every talk the billions of people who use wood, dung, or other biofuels on open fires to cook indoors, causing 3 million premature deaths per year.
“The biggest problem today is a third of humanity doesn’t have hydrocarbons,” Wright told Bryce in 2023. In a 2023 speech to the American Conservation Coalition, a conservative environmental group, he described strictures against financing fossil fuel development as “not just ignorant or bad policy” but “immoral.” His solution: distributing propane stoves as widely as possible, in part through his Bettering Human Lives Foundation.
Here might be the greatest challenge for advocates of climate action: Even if most of the world’s leaders have accepted the reality of anthropogenic climate change, much of the world, especially outside North America and Europe, is still eagerly increasing its use of fossil fuels. In the United States, coal plant shutdowns are being pushed out further and natural gas investment may soon pick up again to power new demand for electricity. Globally, coal use is set to grow over the next few years. That’s thanks in large part to demand from China, the world’s largest emitter and second-largest cumulative emitter behind the United States, defying predictions that demand there was near peaking. The biggest new source of oil demand is India, a country with a per-capita gross domestic product less than 1/30th of the United States.
And so the greatest danger to aggressive action to lower global emissions may not be Chris Wright and his “sober” ideas at the helm of the Department of Energy. It may be that much of the world agrees with him.

Third Way’s latest memo argues that climate politics must accept a harsh reality: natural gas isn’t going away anytime soon.
It wasn’t that long ago that Democratic politicians would brag about growing oil and natural gas production. In 2014, President Obama boasted to Northwestern University students that “our 100-year supply of natural gas is a big factor in drawing jobs back to our shores;” two years earlier, Montana Governor Brian Schweitzer devoted a portion of his speech at the Democratic National Convention to explaining that “manufacturing jobs are coming back — not just because we’re producing a record amount of natural gas that’s lowering electricity prices, but because we have the best-trained, hardest-working labor force in the history of the world.”
Third Way, the long tenured center-left group, would like to go back to those days.
Affordability, energy prices, and fossil fuel production are all linked and can be balanced with greenhouse gas-abatement, its policy analysts and public opinion experts have argued in a series of memos since the 2024 presidential election. Its latest report, shared exclusively with Heatmap, goes further, encouraging Democrats to get behind exports of liquified natural gas.
For many progressive Democrats and climate activists, LNG is the ultimate bogeyman. It sits at the Venn diagram overlap of high greenhouse gas emissions, the risk of wasteful investment and “stranded” assets, and inflationary effects from siphoning off American gas that could be used by domestic households and businesses.
These activists won a decisive victory in the Biden years when the president put a pause on approvals for new LNG export terminal approvals — a move that was quickly reversed by the Trump White House, which now regularly talks about increases in U.S. LNG export capacity.
“I think people are starting to finally come to terms with the reality that oil and gas — and especially natural gas— really aren’t going anywhere,” John Hebert, a senior policy advisor at Third Way, told me. To pick just one data point: The International Energy Agency’s latest World Energy Outlook included a “current policies scenario,” which is more conservative about policy and technological change, for the first time since 2019. That saw the LNG market almost doubling by 2050.
“The world is going to keep needing natural gas at least until 2050, and likely well beyond that,” Hebert said. “The focus, in our view, should be much more on how we reduce emissions from the oil and gas value chain and less on actually trying to phase out these fuels entirely.”
The memo calls for a variety of technocratic fixes to America’s LNG policy, largely to meet demand for “cleaner” LNG — i.e. LNG produced with less methane leakage — from American allies in Europe and East Asia. That “will require significant efforts beyond just voluntary industry engagement,” according to the Third Way memo.
These efforts include federal programs to track methane emissions, which the Trump administration has sought to defund (or simply not fund); setting emissions standards with Europe, Japan, and South Korea; and more funding for methane tracking and mitigation programs.
But the memo goes beyond just a few policy suggestions. Third Way sees it as part of an effort to reorient how the Democratic Party approaches fossil fuel policy while still supporting new clean energy projects and technology. (Third Way is also an active supporter of nuclear power and renewables.)
“We don’t want to see Democrats continuing to slow down oil and gas infrastructure and reinforce this narrative that Democrats are just a party of red tape when these projects inevitably go forward anyway, just several years delayed,” Hebert told me. “That’s what we saw during the Biden administration. We saw that pause of approvals of new LNG export terminals and we didn’t really get anything for it.”
Whether the Democratic Party has any interest in going along remains to be seen.
When center-left commentator Matthew Yglesias wrote a New York Times op-ed calling for Democrats to work productively with the domestic oil and gas industry, influential Democratic officeholders such as Illinois Representative Sean Casten harshly rebuked him.
Concern over high electricity prices has made some Democrats a little less focused on pursuing the largest possible reductions in emissions and more focused on price stability, however. New York Governor Kathy Hochul, for instance, embraced an oft-rejected natural gas pipeline in her state (possibly as part of a deal with the Trump administration to keep the Empire Wind 1 project up and running), for which she was rewarded with the Times headline, “New York Was a Leader on Climate Issues. Under Hochul, Things Changed.”
Pennsylvania Governor Josh Shapiro (also a Democrat) was willing to cut a deal with Republicans in the Pennsylvania state legislature to get out of the Northeast’s carbon emissions cap and trade program, which opponents on the right argued could threaten energy production and raise prices in a state rich with fossil fuels. He also made a point of working with the White House to pressure the region’s electricity market, PJM Interconnection, to come up with a new auction mechanism to bring new data centers and generation online without raising prices for consumers.
Ruben Gallego, a Democratic Senator from Arizona (who’s also doing totally normal Senate things like having town halls in the Philadelphia suburbs), put out an energy policy proposal that called for “ensur[ing] affordable gasoline by encouraging consistent supply chains and providing funding for pipeline fortification.”
Several influential Congressional Democrats have also expressed openness to permitting reform bills that would protect oil and gas — as well as wind and solar — projects from presidential cancellation or extended litigation.
As Democrats gear up for the midterms and then the presidential election, Third Way is encouraging them to be realistic about what voters care about when it comes to energy, jobs, and climate change.
“If you look at how the Biden administration approached it, they leaned so heavily into the climate message,” Hebert said. “And a lot of voters, even if they care about climate, it’s just not top of mind for them.”
Current conditions: A foot of snow piled up on Hawaii's mountaintops • Fresh snow in parts of the Northeast’s highlands, from the New York Adirondacks to Vermont’s Green Mountains, could top 10 inches • The seismic swarm that rattled Iceland with more than 600 relatively low-level earthquakes over the course of two days has finally subsided.
Say what you will about President Donald Trump’s cuts to electric vehicles, renewables, and carbon capture, the administration has given the nuclear industry red-carpet treatment. The Department of Energy refashioned its in-house lender into a financing hub for novel nuclear projects. After saving the Biden-era nuclear funding from the One Big Beautiful Bill Act’s cleaver, the agency distributed hundreds of millions of dollars to specific small modular reactors and rolled out testing programs to speed up deployment of cutting-edge microreactors. The Department of Commerce brokered a deal with the Japanese government to provide the Westinghouse Electric Company with $80 billion to fund construction of up to 10 large-scale AP1000 reactors. But still, in private, I’m hearing from industry sources that utilities and developers want more financial protection against bankruptcy if something goes wrong. My sources tell me the Trump administration is resistant to providing companies with a blanket bailout if nuclear construction goes awry. But legislation in the Senate could step in to provide billions of dollars in federal backing for over-budget nuclear reactors. Senator Jim Risch, an Idaho Republican, previously introduced the Accelerating Reliable Capacity Act in 2024 to backstop nuclear developers still reeling from the bankruptcies associated with the last AP1000 buildout. This time, as E&E News noted, “he has a prominent Democrat as a partner.” Senator Ruben Gallego, an Arizona Democrat who stood out in 2024 by focusing his campaign’s energy platform on atomic energy and just recently put out an energy strategy document, co-sponsored the bill, which authorizes up to $3.6 billion to help offset cost overruns at three or more next-generation nuclear projects.
Nuclear generation set a new global record in 2025, the International Energy Agency said in its latest electricity outlook published last Friday. That’s largely thanks to Japan restarting reactors idled after Fukushima, France ramping up generation at its fleet, and China and India opening new plants. By 2030, however, China will account for 40% of the global increase in nuclear generation. You can see the difference in the growth rate already. Nuclear power worldwide is on track to grow by an average of 2.8% per year, more than double the 1.3% pace of the previous four years. China’s nuclear capacity, by contrast, will grow by an average of 6% per year through the end of the decade.

Roughly 22% of light-duty vehicles sold last year in the U.S. were hybrid and battery electric, up from 20% in 2024. While sales of battery-powered vehicles have fallen, demand for hybrids has only increased, according to estimates from the research firm Omdia that the U.S. Energy Information Administration highlighted in a new analysis. Electric vehicles accounted for just 2% of all registered light-duty vehicles on U.S. roads in 2024, the most recent year for which annual data is available. Sales for 2025 will show a spike, especially around September when Americans rushed to cash in on electric vehicle tax credits before Trump’s phaseout took effect.
The Department of Transportation, meanwhile, proposed boosting the domestic content requirements for federally funded electric vehicle charging stations from 55% to 100%. The Biden administration had waived some “Buy American” requirements for the $5 billion federal program to fund the infrastructure buildout. The proposal would set steep hurdles for projects, likely slowing the rollout of chargers. The agency, Reuters reported, said it believes it must “protect Americans from foreign-made EV charger components that use technology with cybersecurity vulnerabilities.”

Equinor is scaling back its near-term investments in carbon capture and sequestration projects as prices go up and customer demand stagnates. Despite its reputation as what the Carbon Herald called “one of the global standard-bearers for carbon capture and storage,” the Norwegian energy giant said the commercial conditions needed to justify more large-scale investments in carbon pipelines and wells were not yet there. CEO Anders Opedal said during the company’s latest earnings call that, because CCS markets were growing more slowly than previously thought, Equinor would hold off on committing more capital to new projects.
CCS had something of a moment last fall when Google agreed to finance construction of a gas plant equipped with carbon capture technology, as Heatmap’s Matthew Zeitlin wrote. But Trump’s plan to go for the climate killshot, repealing the legal underpinning of all federal regulations on planet-heating emissions, would really dampen demand for CCS in the U.S.
The new U.S.-India trade deal that will lower tariffs on Indian goods to 18% from 25% is set to bolster the country’s booming solar manufacturing industry. The pact represents what Prashant Mathur, chief executive of the solar manufacturer Saatvik Green Energy, described to PV-Tech as a “strategic turning point.” Cutting tariffs by seven percentage points “materially improves cost competitiveness, making U.S. projects more profitable and creating new demand for high-efficiency, Made-in-India products.” Gyanesh Chaudhary, the managing director of Vikram Solar, called the deal a “structural inflection point.” But the trade agreement won’t fix all the problems for Indian solar exporters. New restrictions known as Section 232 tariffs, which raise prices on imports that threaten national security by undercutting domestic manufacturers, are expected to come into effect on India’s exports of polysilicon. A separate antidumping and countervailing duty investigation into whether India is unfairly flooding the U.S. market with cheap crystalline silicon solar cells called for a duty of 123.04%, though nothing has yet been imposed.
The Trump administration, meanwhile, is setting the stage for more coal in the U.S. On Wednesday, according to Bloomberg, Trump plans to sign an executive order directing the military to buy more power from coal-fired plants in a bid to prop up the sector.
Despite Trump’s best attempts to stop it, Orsted is finishing its offshore wind farms in New England and, after that, is expected to save its money for new projects overseas. In its native Europe, the energy giant is preparing for a big multinational buildout in the North Sea. Now the Danish developer is charging ahead in a new market. Australia does not have any operating offshore wind farms. But Orsted just submitted an application for an environmental review of a 2.8 gigawatt project proposed off the coast of Gippsland, Victoria. Together with a second site Orsted started lining up in 2024, the area could host a combined 4.8 gigawatts of turbine capacity, according to Renewables Now.
Yet another fusion energy startup has officially entered the race. Inertia Enterprises, a fusion startup aimed at mimicking the technology that managed for the first time in history to generate more energy than it took to start the reaction, has raised $450 million in a Series A round. The venture firm Bessemer Venture Partners led the round, with backing from Google Ventures, Modern Capital, and Threshold Ventures. “Inertia is building on decades of science and billions of dollars invested to reach the ignition milestone that proved the science,” Jeff Lawson, the co-founder and chief executive of Inertia, said in a statement.
CarbonPlan has a new tool to measure climate risk that comes with full transparency.
On a warming planet, knowing whether the home you’re about to invest your life savings in is at risk of being wiped out by a wildfire or drowned in a flood becomes paramount. And yet public data is almost nonexistent. While private companies offer property-level climate risk assessments — usually for a fee — it’s hard to know which to trust or how they should be used. Companies feed different datasets into their models and make different assumptions, and often don’t share all the details. The models have been shown to predict disparate outcomes for the same locations.
For a measure of the gap between where climate risk models are and where consumers want them to be, look no further than Zillow. The real estate website added a “climate risk” section to its property listings in 2024 in response to customer demand — only to axe the feature a year later at the behest of an industry group that questioned the accuracy of its risk ratings.
Now, however, a new tool that assesses wildfire risk for every building in the United States aims to advance the field through total transparency. The nonprofit research group CarbonPlan launched the free, user-friendly app called Open Climate Risk on Tuesday. It allows anyone to enter an address and view a wildfire risk score, on a scale of zero to 10, along with an explanation of how it was calculated. The underlying methodology, data, and code are all public. It’s the first fully open platform of its kind, according to CarbonPlan.
“Right now, the way science works in the climate risk space is that every model is independently developed at different companies, and we essentially have no idea what’s happening in them. We have no idea if they’re any good,” Oriana Chegwidden, a research scientist at CarbonPlan who led the creation of the tool, told me. “Our hope is that by opening this up, people will be able to start contributing, to help us learn how we can do it better.” That might mean critiquing CarbonPlan’s methods or code, for example, or re-running the model with additional data.
The score itself doesn’t tell you much other than the relative risk between one building and another. But the platform also breaks out the two inputs behind it: burn probability, or the likelihood a building will catch fire in a given year, and “conditional risk,” an estimate of how much of the building’s value would be lost if it does burn, based on projected fire intensity.
The projections are largely based on a U.S. Forest Service dataset that models fire frequency on wildlands throughout the country. CarbonPlan uses additional data on wind speed and direction to predict how a given fire might spread into an urban area.
Users can toggle between risk under the “current” climate and a “future” climate, which jumps about 20 years out. They can also see the distribution of buildings across the spectrum of risk scores at various geographic scales — by state, county, census tract, or census block.
One of CarbonPlan’s hopes is to help people become more informed consumers of climate risk data by helping them understand how it’s put together and what questions they might want to ask. While its model is more crude than others on the market, the tool is explicit about the factors that are not accounted for in the results. The loss estimates are based on a generic building, for example, and do not recognize specific traits like fire-resistant construction materials or landscaping that could make a home more fire resistant. They also don’t consider building-to-building spread. The underlying U.S. Forest Service data is also limited in that it maps vegetation across the country as it existed at the end of 2020 — any changes since then that could have reduced fire-igniting fuels, such as prescribed burns, are not incorporated.
Right now, there’s no industry standard for calculating or communicating climate risk. The Global Association of Risk Professionals recently asked 13 climate risk companies for data on floods, tropical storms, wildfires, and heat at 100 addresses to compare the outputs. The authors found there were “significant disparities,” between estimates of vulnerability and damages at the same locations. When it came to wildfires, specifically, they were unable to even compare the data, because the companies all conveyed the risk using different benchmarks.
The implications of having so many diverging methods and results extend beyond individual homebuying decisions. Insurance companies use climate risk data to set rates; publicly-traded companies use it to make disclosures to investors; policymakers use it to guide community planning and investments in adaptation. Some products might be better suited to one task or another.
Katherine Mach, an environmental science and policy professor at the University of Miami, told me the next step for the field is to have more systematic reporting requirements that help people understand how accurate the data are and what types of decisions they can be used for.
“It’s almost like we need the equivalent of industry standards,” she said. “You’re going to release a climate product? Here’s what you need to clearly communicate.”
CarbonPlan collected feedback from various likely users of the tool throughout the development process, including municipal planners, climate scientists, and consumer advocates. The group also hopes to foster an “iterative cycle of community-driven model development,” spurring other researchers to inspect the data, critique it, add to it, and spin out new versions. This is common practice in other areas of climate science, like Earth system modeling and economic modeling, and has been instrumental in advancing those fields. “There’s nothing like that for climate risk right now,” Chegwidden said.
The first step will be raising more money to support further work, but the goal is to partner with outside researchers on comparative analyses and case studies. Tracy Aquino Anderson, CarbonPlan’s interim executive director, told me they have already heard from one researcher who has a fire risk dataset that could be added to the platform. The group has also been invited to present the platform to two academic climate research groups later this spring.
The problem of black box models exists not just because the field is full of private companies that don’t want to share their code. A study published earlier this month found that only 4% of the most-cited peer-reviewed climate risk studies have made their data and code public, despite journal standards that require transparency.
“When you’re working with climate data, you’re dealing with all of these uncertainties,” Adam Pollack, an assistant professor at the University of Iowa who researches flood risk and the lead author of the paper, told me. “Researchers don’t always understand all of the assumptions that are implicit in choices that they make. That’s fine — we have methods for dealing with that. We do model intercomparisons, we do these synthesis studies as a field. The foundation of that is openness and reusability.”
Though he was not involved in the CarbonPlan project, he said it was exactly what his paper was calling for. For example, CarbonPlan’s “future” calculations are based on an extreme warming scenario that has become controversial among climate scientists. CarbonPlan didn’t choose this scenario — it’s what the Forest Service’s dataset used, and that was the only off-the-shelf data available for the entire United States. But because the underlying code is open-source, critics are free to swap it out for other data they may have access to.
“That’s what’s so great about this,” Pollack said. “People who have different values, assumptions, and expertise, can get new estimates and build a shared understanding.”
