Despite Recent Headlines, Urban Farming Is Not a Climate Villain

News Feed
Wednesday, April 3, 2024

At the end of January, multiple publications including Modern Farmer and Bloomberg ran eye-catching stories on the results of a research study published in Nature. Forbes declared that, “Urban Farming Has a Shockingly High Climate Cost,” a headline that was outright wrong in terms of the study’s findings. Earth.com led with a single, out-of-context data point: “Urban agriculture’s carbon footprint is 6x greater than normal farms.” On Instagram, urban farmers and gardeners began to express anger and frustration. Some commented on media company posts; others posted their own critiques. In February, students at the University of Michigan, where the study was conducted, organized a letter to the researchers pointing out issues with the study. The issue most cited across critiques was simple: When urban farms were separated from community gardens in the study, the higher rate of greenhouse gas emissions reported essentially disappeared. Now, two months later, national advocates for the multi-faceted benefits of growing food and green spaces in cities are working to counter what they see as harmful narratives created by a study they say had design flaws to begin with and was then poorly communicated to the public. Of special concern is funding for the U.S. Department of Agriculture’s (USDA) fledgling Office of Urban Agriculture and Innovative Production, which Congress has been shorting since it was established. A coalition of groups have been pushing to change that in the upcoming farm bill. “We hope the damage isn’t already done, but we fear that publicity around this paper will minimize the advocacy of urban farmers and partners over the past many years and possibly undermine the continued and necessary investment in urban agricultural communities,” reads a letter sent to the study authors by Michigan Food and Farming Systems, the Organic Farming Research Foundation, PASA Sustainable Agriculture, and the Ohio Ecological Food and Farm Association. “We hope the damage isn’t already done, but we fear that publicity around this paper will minimize the advocacy of urban farmers and partners over the past many years…” Their overall critiques of the study start with the sample set of “urban farms.” In a conversation with Civil Eats, lead author Jason Hawes, a Ph.D. student at the University of Michigan, said this his team compiled “the largest data set that we know of” on urban farming. It included 73 urban farms, community gardens, and individual garden sites in Europe and the United States. At each of those sites, the research team worked with farmers and gardeners to collect data on the infrastructure, daily supplies used, irrigation, harvest amounts, and social goods. That data was then used to calculate the carbon emissions embodied in the production of food at each site and those emissions were compared to carbon emissions of the same foods produced at “conventional” farms. Overall, they found greenhouse gas emissions were six times higher at the urban sites—and that’s the conclusion the study led with. But not only is 73 a tiny number compared to the data that exists on conventional production agriculture, said Omanjana Gaswami, an interdisciplinary scientist at the Union of Concerned Scientists (UCS), but lumping community gardens in with urban farms set up for commercial production and then comparing that to a rural system that has been highly tuned and financed for commercial production for centuries doesn’t make sense. “It’s almost like comparing apples to oranges,” she said. “The community garden is not set up to maximize production.” In fact, the sample set was heavily tilted toward community and individual gardens and away from urban farms. In New York City, for example, the only U.S. city represented, seven community gardens run by AmeriCorps were included. Brooklyn Grange’s massive rooftop farms—which on a few acres produce more than 100,000 pounds of produce for markets, wholesale buyers, CSAs, and the city’s largest convention center each year—were not. And what the study found was that when the small group of urban farms were disaggregated from the gardens, those farms were “statistically indistinguishable from conventional farms” on emissions. Aside from one high-emission outlier, the urban farms were carbon-competitive. “They call out the fact that that tiny sample of seven urban farms that are actually production-focused, competitive with conventional agriculture, but that one line just got buried,” said Hannah Quigley, a policy specialist at the National Sustainable Agriculture Coalition (NSAC). This aspect was especially frustrating to urban farming advocates because, as the groups who sent the letter point out, one of their biggest challenges in working with policymakers in D.C. is to get them to “regard urban farming as farming.” Hawes said he found the critiques around lumping community gardens and urban farms together “reasonable” but that he stood by the method. He hadn’t considered including backyard gardens in rural areas in the sample, he said, even though city gardens were. “We were not necessarily attempting to compare urban and rural food production,” he said. “In fact, we chose to use the word conventional specifically because it pointed to the sort of ‘conventional food supply chain,’ which is often what urban agriculture producers are attempting to intervene in.” Not only did taking the community gardens out of the picture change the emissions results, the researchers also found that 63 percent of carbon emissions at all of the sites came not from daily inputs or lack of crop efficiency but from infrastructure, such as building raised beds and trucking in soil. But using recycled materials for infrastructure cut those emissions so much, that if all the sites had done so, that would have been enough for them to close the gap and be competitive with conventional agriculture on greenhouse gas emissions. “That problem can of course be solved by upfront funding,” said Gaswami. “Then, bingo, according to the authors, you have systems with very comparable climate metrics.” Overall, Hawes said he did regret some of the ways media coverage framed the study’s results but that he didn’t feel the framing of the study itself was problematic. “In my opinion, the most important sustainability challenge of our time is climate change, and if we’re gonna talk about sustainability in the context of urban agriculture, we have to talk about carbon emissions,” he said. “The most important sustainability challenge of our time is climate change, and if we’re gonna talk about sustainability in the context of urban agriculture, we have to talk about carbon emissions.” However, while climate scientists and sustainable agriculture advocates agree that addressing the food system’s 22 percent contribution to global greenhouse emissions is critical to meeting climate goals, whether carrots are grown in gardens in Detroit and Atlanta or only on huge commercial farms in the Salinas Valley (or both) won’t likely be a deciding factor. At an event to kick off a new focus on food and agriculture last week, Project Drawdown launched a new series that will focus on food system solutions to climate change. There, Executive Director Jonathan Foley pointed out that the vast majority of food system emissions come from a few big sources: meat and dairy production, deforestation and other land use change (a large portion of which is linked to animal agriculture), and food waste. As Gaswami at UCS noted, that broader context is essential. “The authors . . . don’t at all zoom out to compare this to agriculture’s broader footprint,” Gaswami said, so even if there weren’t clear climate benefits to urban farming—which many say the study didn’t clearly conclude—prioritizing other benefits of growing things in cities might still make more sense. Especially given the climate resilience built into decentralizing and diversifying the food system. Land use is particularly interesting, Quigley at NSAC said, because city farmers and gardeners often reclaim spaces that might otherwise be paved over and developed, adding carbon-holding trees and plants. “Folks who are maintaining community gardens and green spaces in cities to help with water run-off and urban heat island effect providing safe places for community gatherings . . . these are probably people that would be very concerned with their climate impact,” she said. “Can you imagine if they’re gonna be like, ‘Oh my god, should I not be gardening?’” While NSAC did not sign on to the initial letter sent by the coalition of groups, Quigley is working with those farm groups and the members have since talked to Hawes. Disagreements on the study framing still abound, but they’re now working together on policy briefs that will be available to lawmakers if the farm bill process ever picks up again and conversations around funding urban farms are once again on the (picnic) table. “Ultimately, one of the motivations behind this study was the fact that urban agriculture is largely discussed as a really useful sustainability intervention, and this study does not take away from that conclusion,” Hawes said. “I also think that to the degree that this starts conversations about the availability of resources for urban agriculture and the support that is available to urban farmers and gardeners for creating low-carbon solutions—I’m happy with that.” Read More: Congress Puts Federal Support for Urban Farming on the Chopping Block Urban Farms Are Stepping Up Their Roles in Communities Nationwide The IPCC’s Latest Climate Report Is a Final Alarm for Food Systems, Too Supply Chain Impacts of the Key Bridge Collapse.

For plants, urban heat islands don’t mimic global warming

Scientists have found that trees in cities respond to higher temperatures differently than those in forests, potentially masking climate impacts.

It’s tricky to predict precisely what the impacts of climate change will be, given the many variables involved. To predict the impacts of a warmer world on plant life, some researchers look at urban “heat islands,” where, because of the effects of urban structures, temperatures consistently run a few degrees higher than those of the surrounding rural areas. This enables side-by-side comparisons of plant responses.But a new study by researchers at MIT and Harvard University has found that, at least for forests, urban heat islands are a poor proxy for global warming, and this may have led researchers to underestimate the impacts of warming in some cases. The discrepancy, they found, has a lot to do with the limited genetic diversity of urban tree species.The findings appear in the journal PNAS, in a paper by MIT postdoc Meghan Blumstein, professor of civil and environmental engineering David Des Marais, and four others.“The appeal of these urban temperature gradients is, well, it’s already there,” says Des Marais. “We can’t look into the future, so why don’t we look across space, comparing rural and urban areas?” Because such data is easily obtainable, methods comparing the growth of plants in cities with similar plants outside them have been widely used, he says, and have been quite useful. Researchers did recognize some shortcomings to this approach, including significant differences in availability of some nutrients such as nitrogen. Still, “a lot of ecologists recognized that they weren’t perfect, but it was what we had,” he says.Most of the research by Des Marais’ group is lab-based, under conditions tightly controlled for temperature, humidity, and carbon dioxide concentration. While there are a handful of experimental sites where conditions are modified out in the field, for example using heaters around one or a few trees, “those are super small-scale,” he says. “When you’re looking at these longer-term trends that are occurring over space that’s quite a bit larger than you could reasonably manipulate, an important question is, how do you control the variables?”Temperature gradients have offered one approach to this problem, but Des Marais and his students have also been focusing on the genetics of the tree species involved, comparing those sampled in cities to the same species sampled in a natural forest nearby. And it turned out there were differences, even between trees that appeared similar.“So, lo and behold, you think you’re only letting one variable change in your model, which is the temperature difference from an urban to a rural setting,” he says, “but in fact, it looks like there was also a genotypic diversity that was not being accounted for.”The genetic differences meant that the plants being studied were not representative of those in the natural environment, and the researchers found that the difference was actually masking the impact of warming. The urban trees, they found, were less affected than their natural counterparts in terms of when the plants’ leaves grew and unfurled, or “leafed out,” in the spring.The project began during the pandemic lockdown, when Blumstein was a graduate student. She had a grant to study red oak genotypes across New England, but was unable to travel because of lockdowns. So, she concentrated on trees that were within reach in Cambridge, Massachusetts. She then collaborated with people doing research at the Harvard Forest, a research forest in rural central Massachusetts. They collected three years of data from both locations, including the temperature profiles, the leafing-out timing, and the genetic profiles of the trees. Though the study was looking at red oaks specifically, the researchers say the findings are likely to apply to trees broadly.At the time, researchers had just sequenced the oak tree genome, and that allowed Blumstein and her colleagues to look for subtle differences among the red oaks in the two locations. The differences they found showed that the urban trees were more resistant to the effects of warmer temperatures than were those in the natural environment.“Initially, we saw these results and we were sort of like, oh, this is a bad thing,” Des Marais says. “Ecologists are getting this heat island effect wrong, which is true.” Fortunately, this can be easily corrected by factoring in genomic data. “It’s not that much more work, because sequencing genomes is so cheap and so straightforward. Now, if someone wants to look at an urban-rural gradient and make these kinds of predictions, well, that’s fine. You just have to add some information about the genomes.”It's not surprising that this genetic variation exists, he says, since growers have learned by trial and error over the decades which varieties of trees tend to thrive in the difficult urban environment, with typically poor soil, poor drainage, and pollution. “As a result, there’s just not much genetic diversity in our trees within cities.”The implications could be significant, Des Marais says. When the Intergovernmental Panel on Climate Change (IPCC) releases its regular reports on the status of the climate, “one of the tools the IPCC has to predict future responses to climate change with respect to temperature are these urban-to-rural gradients.” He hopes that these new findings will be incorporated into their next report, which is just being drafted. “If these results are generally true beyond red oaks, this suggests that the urban heat island approach to studying plant response to temperature is underpredicting how strong that response is.”The research team included Sophie Webster, Robin Hopkins, and David Basler from Harvard University and Jie Yun from MIT. The work was supported by the National Science Foundation, the Bullard Fellowship at the Harvard Forest, and MIT.

Brisbane 2032 is no longer legally bound to be ‘climate positive’. Will it still leave a green legacy?

Brisbane 2032 was supposed to be the first ‘climate-positive’ Olympic Games. But a quiet change to the host contract puts the commitment in doubt.

When Brisbane was awarded the 2032 Olympic and Paralympic Games, it came with a widely publicised landmark promise: the world’s first “climate-positive” games. The International Olympic Committee had already announced all games would be climate-positive from 2030. It said this meant the games would be required to “go beyond” the previous obligation of reducing carbon emissions directly related to their operations and offsetting or otherwise “compensating” for the rest. In other words, achieving net-zero was no longer sufficient. Now each organising committee would be legally required to remove more carbon from the atmosphere than the games emit. This is in keeping with the most widely cited definition of climate-positive. Both Paris 2024 and Los Angeles 2028 made voluntary pledges. But Brisbane 2032 was the first contractually required to be climate-positive. This was enshrined in the original 2021 Olympic Host Contract, an agreement between the IOC, the State of Queensland, Brisbane City Council and the Australian Olympic Committee. But the host contract has quietly changed since. All references to “climate-positive” have been replaced with weaker terminology. The move was not publicly announced. This fits a broader pattern of Olympic Games promising big on sustainability before weakening or abandoning commitments over time. A quiet retreat from climate positive Research by my team has shown the climate-positive announcement sparked great hope for the future of Brisbane as a regenerative city. We saw Brisbane 2032 as a once-in-a-lifetime opportunity to radically shift away from the ongoing systemic issues underlying urban development. This vision to embrace genuinely sustainable city design centred on fostering circular economies and net positive development. It would have aligned urban development with ecological stewardship. Beyond just mitigating environmental harm, the games could have set a new standard for sustainability by becoming a catalyst to actively regenerate the natural environment. Yet, on December 7 2023, the International Olympic Committee (IOC) initiated an addendum to the host contract. It effectively downgraded the games’ sustainability obligations. It was signed by Brisbane City Council, the State of Queensland, the Australian Olympic Committee and the IOC between April and May 2024. The commitment for the 2032 Brisbane Games to be climate positive has been removed from the Olympic Host Contract. International Olympic Committee Asked about these amendments, the IOC replied it “took the decision to no longer use the term ‘climate-positive’ when referring to its climate commitments”. But the IOC maintains that: “The requirements underpinning this term, however, and our ambition to address the climate crisis, have not changed”. It said the terminology was changed to ensure that communications “are transparent and easily understood; that they focus on the actions implemented to reduce carbon emissions; and that they are aligned with best practice and current regulations, as well as the principle of continual improvement”. Similarly, a Brisbane 2032 spokesperson told The Conversation the language was changed: to ensure we are communicating in a transparent and easily understood manner, following advice from the International Olympic Committee and recommendations of the United Nations and European Union Green Claims Directive, made in 2023. Brisbane 2032 will continue to plan, as we always have, to deliver a Games that focus on specific measures to deliver a more sustainable Games. But the new wording commits Brisbane 2032 to merely “aiming at removing more carbon from the atmosphere than what the Games project emits”. Crucially, this is no longer binding. The new language makes carbon removal an optional goal rather than a contractual requirement. A stadium in Victoria Park violates the 2032 Olympic Host Contract location requirements. Save Victoria Park, CC BY Aiming high, yet falling short Olympic Games have adopted increasingly ambitious sustainability rhetoric. Yet, action in the real world typically falls short. In our ongoing research with the Politecnico di Torino, Italy, we analysed sustainability commitments since the 2006 Winter Olympics in Turin. We found they often change over time. Initial promises are either watered down or abandoned altogether due to political, financial, and logistical pressures. Construction activities for the Winter Olympic Games 2014 in Sochi, Russia, irreversibly damaged the Western Caucasus – a UNESCO World Heritage Site. Rio 2016 failed to clean up Guanabara Bay, despite its original pledge to reduce pollutants by 80%. Rio also caused large-scale deforestation and wetland destruction. Ancient forests were cleared for PyeongChang 2018 ski slopes. Our research found a persistent gap between sustainability rhetoric and reality. Brisbane 2032 fits this pattern as the original promise of hosting climate-positive games is at risk of reverting to business as usual. Victoria Park controversy In 2021, a KPMG report for the Queensland government analysed the potential economic, social and environmental benefits of the Brisbane 2032 games. It said the government was proposing to deliver the climate-positive commitment required to host the 2032 games through a range of initiatives. This included “repurposing and upgrading existing infrastructure with enhanced green star credentials”. But plans for the Olympic stadium have changed a great deal since then. Plans to upgrade the Brisbane Cricket Ground, commonly known as the Gabba, have been replaced by a new stadium to be built in Victoria Park. Victoria Park is Brisbane’s largest remaining inner-city green space. It is known to Indigenous peoples as Barrambin (the windy place). It is listed on the Queensland Heritage Register due to its great cultural significance. Page 90 of the Olympic Host Contract prohibits permanent construction “in statutory nature areas, cultural protected areas and World Heritage sites”. Local community groups and environmental advocates have vowed to fight plans for a Victoria Park stadium. This may include a legal challenge. The area of Victoria Park (64 hectares) compared with Central Park (341h), Regent’s Park (160h), Bois de Vicennes (995h). Save Victoria Park What next? The climate-positive commitment has been downgraded to an unenforceable aspiration. A new Olympic stadium has been announced in direct violation of the host contract. Will Brisbane 2032 still leave a green legacy? Greater transparency and public accountability are needed.

Has the UK's most loathed protest group really stopped throwing soup?

Just Stop Oil says it will disband but does this mark an end to the chaos caused by its climate protests?

Has the UK's most loathed protest group really stopped throwing soup?Justin RowlattBBC News Climate EditorJSO HandoutThe climate action group Just Stop Oil has announced it is to disband at the end of April. Its activists have been derided as attention-seeking zealots and vandals and it is loathed by many for its disruptive direct action tactics. It says it has won because its demand that there should be no new oil and gas licences is now government policy. So, did they really win and does this mark an end to the chaos caused by its climate protests?Hayley Walsh's heart was racing as she sat in the audience at the Theatre Royal Drury Lane on 27 January this year. The 42 year-old lecturer and mother of three tried to calm her breathing. Hollywood star Sigourney Weaver was onstage in her West End debut production of Shakespeare's The Tempest. But Hayley, a Just Stop Oil activist, had her own drama planned.As Weaver's Prospero declaimed "Come forth, I say," Hayley sprang from her seat and rushed the stage with Richard Weir, a 60-year-old mechanical engineer from Tyneside. They launched a confetti cannon and unfurled a banner that read "Over 1.5 Degrees is a Global Shipwreck" - a reference to the news that 2024 was the first year to pass the symbolic 1.5C threshold in global average temperature rise, and a nod to the shipwreck theme in the play. It was a classic Just Stop Oil (JSO) action. The target was high profile and would guarantee publicity. The message was simple and presented in the group's signature fluorescent orange.The reaction of those affected was also a classic response to JSO. Amid the boos and whistles you can hear a shout of "idiots". "Drag them off the stage", one audience member can be heard shouting, "I hope you [expletive] get arrested," another says.JSO is a UK-based environmental activist group that aims to end fossil fuel extraction and uses direct action to draw attention to its cause. It has been called a "criminal cult" and its activists branded "eco-loons" by the Sun. The Daily Mail has described it as "deranged" and says its members have "unleashed misery on thousands of ordinary people though their selfish antics".JSO HandoutIt is the group's road protests that have probably caused the most disruption – and public anger.The group has thrown soup at a Van Gogh in the National Gallery, exploded a chalk dust bomb during the World Snooker Championship in Sheffield, smashed a cabinet containing a copy of the Magna Carta at the British Library, sprayed temporary paint on the stones of Stonehenge and even defaced Charles Darwin's grave.But it is the group's road protests that have probably caused the most disruption – and public anger. In November 2022, 45 JSO members climbed gantries around the M25 severely disrupting traffic for over four days. People missed flights, medical appointments and exams as thousands of drivers were delayed for hours. The cost to the Metropolitan Police was put at £1.1 million.Just Stop Oil was born out of Extinction Rebellion (XR). XR – founded in 2018 - brought thousands of people onto the streets in what were dubbed "festivals of resistance". They came to a peak in April 2019, when protestors brought parts of the capital to a halt for more than a week and plonked a large pink boat in the middle of Oxford Circus.The spectacle and disruption XR caused generated massive media attention, but the police were furious. Hundreds of officers were diverted from frontline duties and by the end of 2019 the bill for policing the protests had reached £37m.And behind the scenes XR was riven by furious debates about tactics. Many inside the movement said it should be less confrontational and disruptive but a hard core of activists argued it would be more effective to double down on direct action.It became clear that there was room for what Sarah Lunnon, one of the co-founders of Just Stop Oil, calls "a more radical flank". They decided a new, more focused operation was needed, modelled on earlier civil disobedience movements like the Suffragettes, Gandhi's civil disobedience campaigns and the civil rights movement in the US.The group was formally launched on Valentine's Day, 2022. It was a very different animal to XR. Instead of thousands of people taking part in street carnivals, JSO's actions involved a few committed activists. A small strategy group oversaw the campaign and meticulously planned its activities. A mobilisation team worked to recruit new members, and another team focused on supporting activists after they were arrested.Getty ImagesJust Stop Oil protesters invading a Rugby matchThe dozens of actions the group has carried out generated lots of publicity, but also massive public opposition. There were confrontations between members of the public and protestors and an outcry from politicians across all the main political parties.The police said they needed more powers to deal with this new form of protest and they got them. New offences were created including interfering with national infrastructure, "locking on" – chaining or gluing yourself to something – and tunnelling underground. Causing a public nuisance also became a potential crime – providing the police with a powerful new tool to use against protestors who block roads.In the four years since it was formed dozens of the group's supporters have been jailed. Five activists were handed multi-year sentences for their role in the M25 actions in 2022. Those were reduced on appeal earlier this month but are still the longest jail terms for non-violent civil disobedience ever issued.Senior JSO members deny the crackdown had anything to do with the group's decision to "hang up the hi-vis" – as its statement this week announcing the end of campaign put it.JSO's public position is that it has won its battle. "Just Stop Oil's initial demand to end new oil and gas is now government policy, making us one of the most successful civil resistance campaigns in recent history," the group claimed.The government has said it does not plan to issue any new licences for oil and gas production but strongly denies its policies have a link to JSO. Furthermore, the Prime Minister's official spokesperson told journalists: "We have been very clear when it comes to oil and gas that it has a future for decades to come in our energy mix."And the group's wider goal – to end the production of oil and gas – has manifestly not been achieved. The members of the group I spoke to for this article all agree the climate crisis has deepened.AFPA protest at the Aston Martin showroom in central LondonIn the face of stiffer sentences, some climate campaigners have said they will turn to more clandestine activities. One new group says it plans a campaign of sabotage against key infrastructure. In a manifesto published online it says it plans to "kickstart a new phase of the climate activist movement, aiming to shut down key actors of the fossil fuel economy."That's not a direction the JSO members I spoke to said they wanted to go. Sarah Lunnon said a key principle of JSO and the civil disobedience movement generally was that activists would take responsibility for their actions. One of the first questions new joiners were asked is whether they would be willing to be locked up."As corporations and billionaires corrupt political systems across the world, we need a different approach. "We are creating a new strategy, to face this reality and to carry our responsibilities at this time," the group says, suggesting they may be planning to form a new movement.JSO's most high-profile figure, Roger Hallam, is one of the five activists convicted for their role in the M25 protests. In a message from his prison cell he acknowledged that JSO has only had a "marginal impact". That is "not due to lack of trying," he said. The failure lay with the UK's "elites and our leaders" who had walked away from their responsibility to tackle the climate crisis, Hallam claimed. A hint perhaps that the group's new focus might be on the political system itself.JSO has said its last protest – to be held at the end of April – will mark "the end of soup on Van Goghs, cornstarch on Stonehenge and slow marching in the streets". But don't believe it. When pressed, the JSO members I spoke to said they may well turn back to disruptive tactics but under a new name and with a new and as yet unspecified objective.

Amid Trump Cuts, Climate Researchers Wait for the Ax to Fall

Climate experts whose research is funded by federal grants hide, whisper and wait for their jobs to disappear

Climate Researchers Wait for the Ax to FallClimate experts whose research is funded by federal grants hide, whisper and wait for their jobs to disappearBy Ariel Wittenberg, Chelsea Harvey & E&E News The Trump administration has slashed jobs and funding at the National Institutes of Health. Mark Wilson/Newsmakers/Getty ImagesCLIMATEWIRE | The National Institutes of Health has canceled grants for research on diversity, Covid-19 and vaccines. Climate scientists are hoping their work won’t be next — but fear it could be.“We are holding our breaths because we know we are on their list of targets,” said Marsha Wills-Karp, chair of the Johns Hopkins University Department of Environmental Health and Engineering. “It feels like it’s been slash and burn. We are hopeful they won’t get to climate, but we know it’s not likely.”Researchers in her department have received NIH grants to study the effects of wildfire air pollution on preterm birth rates and how hotter weather is affecting the health of babies at birth, measured by their weight and potential complications. They’re also studying how climate change is affecting nutrition.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

But there’s reason to think they could be, and soon.Earlier this week, ProPublica reported on an internal NIH memo that outlined how the agency will no longer fund research on the health effects of climate change. It followed a story in Mother Jones showing that NIH had ended three climate-related programs, including the Climate Change and Health Initiative. The program was created in 2022 and has had annual congressional appropriations of $40 million, according to a December NIH report that was taken offline by the agency earlier this year.“HHS is taking action to terminate research funding that is not aligned with NIH and HHS priorities,” said Emily Hilliard, a department spokesperson.“As we begin to Make America Healthy Again, it’s important to prioritize research that directly affects the health of Americans,” she added. “We will leave no stone unturned in identifying the root cause of the chronic disease epidemic as part of our mission to Make America Healthy Again.”She did not respond to questions about whether HHS believes that research into the health effects of heat and other types of extreme weather are aligned with agency priorities or whether HHS believes that heat waves affect the health of Americans. NIH did not respond to a request for comment.Heat is the No. 1 weather-related killer in the U.S., according to the Centers for Disease Control and Prevention, an agency within HHS. Heat caused or contributed to at least 2,300 deaths in 2023, CDC records show.In addition to turbocharging temperatures, climate change can affect people's health by increasing the prevalence of vector-borne diseases and the number of wildfires, whose smoke has been shown to increase asthma and cause cardiovascular problems.Those connections have long been studied with funding from the National Institutes of Environmental Health Sciences. Then in 2022, NIH broadened the scope of federal funding for climate health research, directing each of the agency’s 26 centers and institutes to study the dangers of climate change. At the time, the agency said “a mounting number of assessments and reports provide undeniable evidence that climate change is resulting in … direct and indirect consequences for human health and well-being.”Most of the climate researchers contacted by POLITICO's E&E News declined to talk publicly about their funding, citing concerns about their grants being rescinded if they spoke to the media.One researcher who was awarded federal funding said some experts in the climate and health field are pausing work related to their grants, like hiring.Others have turned down speaking requests because they're concerned about attracting attention from the Trump administration. Their work often focuses on how extreme weather has disproportional effects on the health of communities of color, according to several researchers who were granted anonymity for fear of retribution. One said that they declined a speaking invitation to avoid “accidentally us[ing] language we are not supposed to and then be told our language is not compliant with various executive orders” on diversity and equality.“We’ve been told we need to comply with those executive orders as federal grantees, but it’s hard to do if you are funded for something that the name is something you are not allowed to say,” the researcher said. “No one wants to do a social media post or a webinar or an event that might get them in trouble.”An annual conference hosted by NIH, Boston University and the Harvard School of Public Health was postponed earlier this month.Linda Birnbaum, who led the National Institutes of Environmental Health Sciences until 2017, said that during the first Trump administration, researchers were able to circumvent directives by wording grant applications as “climate and health” rather than “climate change.”“It worked then. I don’t think that will work anymore,” she said.Reprinted from E&E News with permission from POLITICO, LLC. Copyright 2025. E&E News provides essential news for energy and environment professionals.
