Federal funding freeze endangers climate-friendly agriculture progress

For decades, environmental and farm groups pushed Congress, the USDA and farmers to adopt new conservation programs, but progress came in incremental steps. With each Farm Bill, some lawmakers threaten to whittle down conservation programs, but they have essentially managed to survive and even expand.

The country’s largest farm lobby, the American Farm Bureau Federation, had long denied the realities of climate change, fighting against climate action and adopting official policy positions that question the scientific consensus that climate change is human-caused. Its members—the bulk of American farmers—largely adhered to the same mindset.

But as the realities of climate change have started to hit American farmers on the ground in the form of more extreme weather, and as funding opportunities have expanded through conservation and climate-focused programs, that mindset has started to shift.

“They were concerned about what climate policy meant for their operations,” Bonnie said. “They felt judged. But we said: Let’s partner up.”

The Trump administration’s rollbacks and freezes threaten to stall or undo that progress, advocacy groups and former USDA employees say.

“We created this enormous infrastructure. We’ve solved huge problems,” Bonnie added, “and they’re undermining all of it.”

“It took so long,” Stillerman said. “The idea that climate change was happening and that farmers could be part of the solution, and could build more resilient farming and food systems against that threat—the IRA really put dollars behind that. All of that is at risk now.”

Burk says he plans to continue with conservation and carbon-storing practices on his Michigan farm, even without conservation dollars from the USDA.

But, he says, many of his neighboring farmers likely will stop conservation measures without the certainty of government support.

“So many people are struggling, just trying to figure out how to pay their bills, to get the fuel to run their tractors, to plant,” he said. “The last thing they want to be doing is sitting down with someone from NRCS who says, ‘If I do these things, maybe I’ll get paid in a year.’ That’s not going to happen.”

EPA accused of faking criminal investigation to claw back climate funds

Citibank has until March 15 to provide more information on orders to freeze funding. More details on that front were shared today, however, in a court filing in a lawsuit raised by Climate United—one of eight NCIF awardees whose funding was suddenly frozen.

In a motion opposing a request for a temporary restraining order forcing Citibank to unfreeze the funds, Citibank argued that it plays only an administrative role in managing accounts.

According to Citibank, it cannot be liable for freezing the funds because it’s legally required to follow instructions from the EPA and the Department of the Treasury, and those agencies ordered Citibank “to pause all further disbursements from GGRF accounts, including those held by Climate United, until further notice.”

Citibank told the US district court that orders came to freeze the funding after “the government informed Citibank that the GGRF program was subject to an ongoing criminal investigation.”

Supposedly, the FBI received “credible information” that Climate United’s Citibank account was “involved in possible criminal violations,” allegedly including conspiracy to defraud the United States and wire fraud, Citibank’s filing said. In a footnote, Citibank said that it also “learned” that the EPA was “deeply” concerned about “matters of financial mismanagement, conflicts of interest, and oversight failures.”

So, freezing the funds was viewed as necessary, the filing alleged, to prevent “misuse of funds.” And Citibank claimed it had no authority to dispute “lawful” orders.

“Citibank is not vested with discretion to second-guess the government’s concerns regarding the ‘misconduct, waste, conflicts of interest, and potential fraud’ that the government has stated is occurring,” Citibank’s filing said.

Climate United, which describes itself as “a public-private investment fund that removes financial barriers to clean technologies,” said in a press release that freezing the funds had already harmed “hard-working Americans who are struggling to pay for groceries and keep the lights on.”

“Small businesses and developers are unable to draw committed funds for project expenses, critical programs are delayed or paused, and Climate United’s reputation as a lender is impacted,” Climate United said, rounding up stories from stakeholders already struggling through the freeze and urging, “this isn’t about politics; it’s about economics.”

What the EPA’s “endangerment finding” is and why it’s being challenged


Getting rid of the justification for greenhouse gas regulations won’t be easy.

Credit: Mario Tama/Getty Images

A document that was first issued in 2009 would seem an unlikely candidate for making news in 2025. Yet the past few weeks have seen a steady stream of articles about an analysis first issued by the Environmental Protection Agency (EPA) in the early years of Obama’s first term: the endangerment finding on greenhouse gases.

The basics of the document are almost mundane: Greenhouse gases are warming the climate, and this will have negative consequences for US citizens. But it took a Supreme Court decision to get written in the first place, and it has played a role in every attempt by the EPA to regulate greenhouse gas emissions across multiple administrations. And, while the first Trump administration left it in place, the press reports we’re seeing suggest that an attempt will be made to eliminate it in the near future.

The only problem: The science in which the endangerment finding is based on is so solid that any ensuing court case will likely leave its opponents worse off in the long run, which is likely why the earlier Trump administration didn’t challenge it.

Get comfortable, because the story dates all the way back to the first Bush administration.

A bit of history

One of the goals of the US’s Clean Air Act, first passed in 1963, is to “address the public health and welfare risks posed by certain widespread air pollutants.” By the end of the last century, it was becoming increasingly clear that greenhouse gases fit that definition. While they weren’t necessarily directly harmful to the people inhaling them—our lungs are constantly being filled with carbon dioxide, after all—the downstream effects of the warming they caused could certainly impact human health and welfare. But, with the federal government taking no actions during George W. Bush’s time in office, a group of states and cities sued to force the EPA’s hand.

That suit eventually reached the Supreme Court in the form of Massachusetts v. EPA, which led to a ruling in 2007 determining that the Clean Air Act required the EPA to perform an analysis of the dangers posed by greenhouse gases. That analysis was done by late 2007, but the Bush administration simply ignored it for the remaining year it had in office. (It was eventually released after Bush left office.)

That left the Obama-era EPA to reach essentially the same conclusions that the Bush administration had: greenhouse gases are warming the planet. And that will have various impacts—sea-level rise, dangerous heat, damage to agriculture and forestry, and more.

That conclusion compelled the EPA to formulate regulations to limit the emission of greenhouse gases from power plants. Obama’s EPA did just that, but came late enough to still be tied up in courts by the time his term ended. The regulations were also formulated before the plunge in the cost of renewable power sources, which have since led to a drop in carbon emissions that have far outpaced what the EPA’s rules intended to accomplish.

The first Trump administration formulated alternative rules that also ended up in court for being an insufficient response to the conclusions of the endangerment finding, which ultimately led the Biden administration to start formulating a new set of rules. And at that point, the Supreme Court decided to step in and rule on the Obama rules, even though everyone knew they would never go into effect.

The court indicated that the EPA needed to regulate each power plant individually, rather than regulating the wider grid, which sent the Biden administration back to the drawing board. Its attempts at crafting regulations were also in court when Trump returned to office.

There were a couple of notable aspects to that last case, West Virginia v. EPA, which hinged on the fact that Congress had never explicitly indicated that it wanted to see greenhouse gases regulated. Congress responded by ensuring that the Inflation Reduction Act’s energy-focused components specifically mentioned that these were intended to limit carbon emissions, eliminating one potential roadblock. The other thing is that, in this and other court cases, the Supreme Court could have simply overturned Massachusetts v. EPA, the case that put greenhouse gases within the regulatory framework of the Clean Air Act. Yet a court that has shown a great enthusiasm for overturning precedent didn’t do so.

Nothing dangerous?

So, in the 15 years since the EPA initially released its endangerment findings, they’ve resulted in no regulations whatsoever. But, as long as they existed, the EPA is required to at least attempt to regulate them. So, getting rid of the endangerment findings would seem like the obvious thing for an administration led by a president who repeatedly calls climate change a hoax. And there were figures within the first Trump administration who argued in favor of that.

So why didn’t it happen?

That was never clear, but I’d suggest at least some members of the first Trump administration were realistic about the likely results. The effort to contest the endangerment finding was pushed by people who largely reject the vast body of scientific evidence that indicates that greenhouse gases are warming the climate. And, if anything, the evidence had gotten more decisive in the years between the initial endangerment finding and Trump’s inauguration. I expect that their effort was blocked by people who knew that it would fail in the courts and likely leave behind precedents that made future regulatory efforts easier.

This interpretation is supported by the fact that the Trump-era EPA received a number of formal petitions to revisit the endangerment finding. Having read a few (something you should not do), they are uniformly awful. References to supposed peer-reviewed “papers” turn out to be little more than PDFs hosted on a WordPress site. Other arguments are based on information contained in the proceedings of a conference organized by an anti-science think tank. The Trump administration rejected them all with minimal comment the day before Biden’s inauguration.

Biden’s EPA went back and made detailed criticisms of each of them if you want to see just how laughable the arguments against mainstream science were at the time. And, since then, we’ve experienced a few years of temperatures that are so high they’ve surprised many climate scientists.

Unrealistic

But the new head of the EPA is apparently anything but a realist, and multiple reports have indicated he’s asking to be given the opportunity to go ahead and redo the endangerment finding. A more recent report suggests two possibilities. One is to recruit scientists from the fringes to produce a misleading report and roll the dice on getting a sympathetic judge who will overlook the obvious flaws. The other would be to argue that any climate change that happens will have net benefits to the US.

That latter approach would run into the problem that we’ve gotten increasingly sophisticated at doing analyses that attribute the impact of climate change on the individual weather disasters that do harm the welfare of citizens of the US. While it might have been possible to make a case for uncertainty here a decade ago, that window has been largely closed by the scientific community.

Even if all of these efforts fail, it will be entirely possible for the EPA to construct greenhouse gas regulations that accomplish nothing and get tied up in court for the remainder of Trump’s term. But a court case could show just how laughably bad the positions staked out by climate contrarians are (and, by extension, the position of the president himself). There’s a small chance that the resulting court cases will result in a legal record that will make it that much harder to accept the sorts of minimalist regulations that Trump proposed in his first term.

Which is probably why this approach was rejected the first time around.

Elawady decided to investigate why the Houston derecho’s structural damage was so much more extensive than one might expect. He and his colleagues analyzed the impact of the derecho on five of the city’s most notable buildings: The Chevron Building Auditorium, the CenterPoint Energy Plaza, the El Paso Energy Building, the RRI Energy Plaza, and the Wedge International Tower.

The Chevron Building Auditorium, for instance, suffered significant damage to its cladding and shattered glass windows, mostly on the side facing another skyscraper: the Chevron Corporation Tower. The CenterPoint Energy Plaza’s damage to its double-skin facade was concentrated on one corner that had two tall buildings facing it, as was the damage to two corners of the El Paso Energy building. This suggested a wind-channeling effect might have played a role in that damage.

Next Elawady et al. conducted wind tunnel experiments at the FIU Natural Hazards Engineering Research Infrastructure’s “Wall of Wind” facility to determine how the winds may have specifically caused the observed damage. They placed a revolving miniature tall building in the tunnel and blasted it with wind speeds of up to 70 meters per second while placing an identical mini-model at increasing distances from the first to mimic possible interference from nearby buildings.

The results confirmed the team’s working hypothesis. “When strong winds move through a city, they can bounce due to interference between tall buildings. This increases pressure on walls and windows, making damage more severe than if the buildings were isolated,” said co-author Omar Metwally, a graduate student at FIU. For example, in the case of the Chevron Building Auditorium, the channeling effects intensified the damage, particularly at higher elevations.

“On top of this, downbursts create intense, localized forces which can exceed typical design values for hurricanes, especially on the lower floors of tall buildings,” Metwally added. The problem is only likely to worsen because of accelerating climate change. Glass facades seem to be particularly vulnerable to this kind of wind damage, and the authors suggest current design and construction guidelines for such elements should be re-evaluated as a result of their findings.

Despite court orders, climate and energy programs stalled by Trump freeze


Chief of the EPA is also trying to claw back $20 billion, citing alleged wrongdoing.

President Donald Trump’s freeze on federal funding shows little sign of thawing for climate, energy and environmental justice programs.

Despite two federal court orders directing the administration to resume distributing federal grants and loans, at least $19 billion in Environmental Protection Agency funding to thousands of state and local governments and nonprofits remained on hold as of Feb. 14, said environmental and legal advocates who are tracking the issue.

EPA Administrator Lee Zeldin has vowed to seek return of an additional $20 billion the agency invested last year in the Greenhouse Gas Reduction Fund program, calling for a Department of Justice investigation into what he characterized as a “scheme… purposefully designed to obligate all of the money in a rush job with reduced oversight.”

Environmental advocates said Zeldin was unfairly smearing the Greenhouse Gas Reduction Fund, or “green bank,” program, on which EPA worked for more than a year with the Treasury Department to design a standard financial agent arrangement—the kind the government has used many times before to collect and distribute funds.

Critics believe the Trump administration, thwarted last week in its effort to get an appeals court to reinstate its sweeping government-wide freeze on federal funding, is resorting to a new tactic—labeling individual programs as nefarious or fraudulent. Although that approach has met with some success—a federal judge last week allowed the Federal Emergency Management Agency to freeze $80 million in funding from a migrant shelter program in New York—legal experts said courts will be looking for specifics and evidence, not broad assertions that programs are improper.

“They cannot challenge an entire program based on charges of fraud and waste,” said Jillian Blanchard, a vice president of the nonprofit Lawyers for Good Government. “If they had actual concerns about fraud or waste, they would need to follow clear procedures and protocols in the regulations, going grant by grant to address this, but that’s not what’s happening here. They are challenging entire programs whole cloth without evidence.

“The executive does not have the authority to change policies simply because they don’t like them,” Blanchard said at a virtual briefing for reporters on Friday. “Congress makes the law, not the president and certainly not Elon Musk,” she said, referring to the billionaire donor whom Trump has deputized to cut government spending.

Feeling the freeze

Across the country, the spending freeze has thrown into chaos the environmental, resilience and community improvement programs that Congress authorized in the Inflation Reduction Act of 2022. Among the efforts on hold: clean drinking water, air monitoring, hurricane recovery and electric school buses.

“Real people on the ground are being hurt by the stop-start situation,” said Blanchard, whose group is working with the Natural Resources Defense Council on the cases of 230 grantees in 44 states.

Grantees are in a state of confusion because they have not heard directly from EPA, she said.

Michelle Roos, executive director of the Environmental Protection Network, a coalition of former EPA employees that is also working with Lawyers for Good Government, said many grantees are not sure what is happening because the agency’s employees have been forbidden to talk to people outside of the agency.

Several grantees reached by Inside Climate News said that they were not talking to the press, or did not want to say whether or not they could access their funding.

MDC, a nonprofit in Durham, North Carolina, along with the Hispanic Federation, was supposed to receive a $3 million environmental justice community change grant for disaster recovery and resilience programs in Latino areas of eastern North Carolina.

“We were thrilled to receive federal support to do this work, but unfortunately, like many others, we have experienced an interruption in accessing this funding,” said Clarissa Goodlett, MDC’s director of communications.

Many neighborhoods, especially those that are home to low-income, Black and Latino residents, are still rebuilding from hurricanes that hit in 2016 and 2018.

During the storms, rural counties in eastern North Carolina did not provide real-time emergency alerts or evacuation orders in Spanish, according to Enlace Latino NC, a Spanish-language digital news outlet.

The MDC grant would help Latinos connect with local governments to ensure their communities are included in discussions and decisions about the impact of climate disasters.

“We are investigating and pursuing whatever options and channels are available to us to ensure we can follow through on our commitment to communities in eastern North Carolina,” Goodlett said.

Dorothy Darr, executive director of the Southwest Renewal Foundation in High Point, near Greensboro, North Carolina, said she doesn’t know if the group’s $18.4 million grant is frozen. Southwest Renewal is teaming up with eight partners to support not only environmental projects—tree planting, water testing and building an urban greenway—but also workforce training and infrastructure improvements. These include upgrades to old, leaking sewer lines and inefficient HVAC systems and a new energy-efficient “cool” roof at a Guilford County school.

The money would also pay for nine new public electric vehicle charging stations, anti-littering campaigns and other improvements in historically Black and low-income neighborhoods in the southwest part of the city.

Darr said the foundation only recently received an account number from the EPA, and she plans to try to access the funds Monday.

“The grant title”—Environmental and Climate Justice Community Change Grants—”has the words ‘environment’ and ‘justice’ in it,” Darr said. “If you’re just slashing programs based on words, then we’re a sitting duck.”

In Texas, the nonprofit group Downwiders at Risk received word in a Feb. 4 letter that it had received a $500,000 EPA environmental justice “collaborative problem-solving” grant it had applied for last year. The money was to be used to install community air monitors in neighborhoods near Dallas. But the notification didn’t provide instructions on how to access the money, and no followup ever came.

Executive Director Caleb Roberts called around his local EPA office, but no one could give answers.

“People are still unsure. Our project officer at the EPA has no idea. I’ve emailed people higher up,” Roberts said. “They have no idea if things are funded or not. They are just as in the dark as we are.”

Downwinders’ award letter said they had 21 days to pull their first block of funding. If no instructions to access the money arrive before then, Robert worries they may lose it.

The city of New Haven, Connecticut, only received word on Jan. 21—the day after Trump’s inauguration—that it and its local nonprofit partners had received a $20 million environmental justice community change grant, according to Steve Winter, who heads up the city’s Office of Climate and Sustainability. But he had never been able to access the funds; the online system originally said “unavailable for payment;” that changed on Feb. 10 to “suspended.”

The money was supposed to help fund whole-home energy efficiency retrofits in a city where one-quarter of the population lives in poverty and where energy costs have skyrocketed since the start of the Russia-Ukraine war, Winter said. Connecticut, like much of New England, relies heavily on heating oil in winter—not only the most expensive home heating fuel, but the most polluting. The grants also would have helped with asbestos and mold remediation in the homes, which are necessary before energy efficiency upgrades can be done.

Winter said the city has warned its partners that they now may need to lay off staff that they’ve hired for outreach for energy efficiency programs, and the future of a community geothermal project is at risk. Also up in the air: a local food rescue organization’s plans to increase staff and food storage capacity.

“People might say, oh this environmental justice grant is some frivolous thing, but it’s about helping people with quality affordable housing, with lowering their energy bills, alleviating hunger in the community, providing affordable transportation options,” Winter said. “These are all trying to meet basic needs that also have an environmental impact.”

A “rush job” accusation

The Trump administration’s drive to root out “diversity, equity and inclusion,” or DEI programs, throughout the government has swept up environmental justice programs at EPA, even though the two are distinct policy initiatives similar only in that they often involve people of color. After taking office two weeks ago, the first employees that Zeldin announced he was eliminating from the agency were those in DEI and environmental justice programs.

“The previous Administration used DEI and Environmental Justice to advance ideological priorities, distributing billions of dollars to organizations in the name of climate equity,” Zeldin said in a statement. “This ends now. We will be good stewards of tax dollars and do everything in our power to deliver clean air, land, and water to every American, regardless of race, religion, background, and creed.”

Last week, as thousands more employees at EPA and other federal agencies were placed on administrative leave or accepted the deferred retirement offer, Zeldin escalated his critiques on environmental justice and climate programs.

In a video first posted on X, Musk’s social media platform, on Wednesday night,

Zeldin called out $20 billion for the Greenhouse Gas Reduction Fund that he said had been “parked at an outside financial institution,” suggesting that the money was given away in a “rush job” in the waning days of the Biden administration. In fact, the money in question was awarded to eight recipients in August, well before the election. The program’s defenders say it went through a rigorous selection process that began more than a year before the awards were announced.

The $20 billion falls under two programs within the EPA’s Greenhouse Gas Reduction Fund and is intended to support nonprofits and financial institutions to serve as green banks. The eight recipients, which received between $400,000 and $7 billion, are supposed to use that money to finance projects by businesses and nonprofits around the country that would cut climate pollution. Much of the money is dedicated to low-income communities, where it is often harder for businesses to raise private financing.

The recipients have already begun using the funding to support businesses, including $250 million for an electric truck financing program beginning at the ports of Los Angeles and Long Beach, $31.8 million in financing for a solar project for the University of Arkansas System and $10.8 million for solar projects on Tribal lands in Oregon and Idaho.

Unlike most of the grant recipients under the IRA, who draw down their money over time as work is completed, the green banks already received their money. Zealan Hoover, who administered IRA programs at EPA during the Biden administration, said the money was placed into bank accounts at Citibank under terms of financial agreements worked out with the Treasury Department.

Although EPA had never used such an outside financial agent before, the Treasury Department had made such agreements with outside institutions many times in the past to distribute or collect money. The system used for electronic federal tax payments, for expanding access to retirement savings and for getting money to assist businesses during the COVID-19 pandemic are just a few of the examples he cited.

“What is underway is not a good-faith effort to fight fraud,” Hoover said. “If it was, federal agencies would not be firing thousands of employees who are hired to conduct robust management and oversight of these programs.”

Zeldin said he was calling for termination of the financial agent agreement for the green bank program, and for the immediate return of the entire fund balance to the United States Treasury. He also said he was referring the issue to the EPA’s Office of the Inspector General and Congress and would “work with the U.S. Department of Justice.” In fact, EPA’s inspector general was dismissed in the early days of the Trump administration along with those at 16 other agencies. EPA’s press office said the agency currently has an acting inspector general but when asked, did not respond with that person’s name. EPA did not answer further questions on the financial agent program, referring only to Zeldin’s video post.

“The American public deserves a more transparent and accountable government than what transpired the past four years,” Zeldin said in the post. “We take our obligations under the law as seriously as it gets. I’ve directed my team to find your ‘gold bars’ and they found them. Now we will get them back inside of control of government as we pursue next steps.”

Citibank declined to comment. Each of the eight recipients of the green bank funds either declined to comment or did not reply to requests for comment.

“Hard for courts to catch up”

What happens next for the grant recipients is not entirely clear. Courts have issued temporary restraining orders to halt the funding freeze until the issue can be argued on its merits. In a five-page order issued Feb. 10, U.S. District Judge John McConnell Jr. of Rhode Island said that it was clear that the administration had in some instances continued “to improperly freeze federal funds.”

McConnell ordered the administration to “immediately end any funding pause,” but EPA and other agencies that are administering IRA climate programs, like the Department of Energy, are continuing to hold back funds.

“We’re talking about funding for families to make upgrades that help them save on their monthly energy bill, funding for people to buy energy efficient appliances and to retrofit their home so that cold air stays out in the winter and hot air stays out in the summer,” said Sen. Patty Murray, D-Wash., the vice chair of the Senate Appropriations Committee, in a briefing with reporters on Thursday. “Those programs aren’t just important to tackling the climate crisis. They are saving our families money.”

“What is painfully clear is that Trump’s illegal funding freeze is causing chaos and confusion,” Murray said.

But Murray and other Democrats, who helped shepherd the IRA to passage in 2022 with no Republican votes, now have little power to force a showdown in a Congress controlled by Republicans. And although multiple studies have shown that most of the $379 billion Congress devoted to funding the clean energy transition in that legislation has flowed to Republican districts, there has been little sign so far that GOP leaders are inclined to clash with the administration. In a few instances, Republicans have sought protection for individual programs that affect their own states.

Blanchard and other legal experts said the courts will have the final say on whether the Trump administration can continue to selectively freeze federal funds. But the decisions may not come soon enough for the programs that are relying on the money they were promised.

“The problem is, as a practical matter, it’s very hard for the courts to catch up,” said Richard Lazarus, an environmental law professor at Harvard Law School. “And the impact on these communities is immediate. The place is closed down, the services aren’t provided for these communities. So the impact can be immediate and devastating, and the practical remedy may be illusory.”

Lazarus was one of the legal scholars writing about environmental justice in the 1990s, before President Bill Clinton signed the first executive order to address communities that suffer a disproportionate burden of pollution. He said that although these communities now “have a fight on their hands,” it is not a new situation for them.

“It’s not as though the government turning against their hardship is something the EJ communities don’t know,” he said. “They don’t welcome it, but they know what this is. It’s how they’ve lived their lives for decades. They fought, and they’ll continue to fight. And that’ll be fighting in cases and lawsuits, and it’ll be fighting politically.”

Man offers to buy city dump in last-ditch effort to recover $800M in bitcoins

Howells told The Times that he envisions cleaning up the site and turning it into a park, but the council’s analysis seems to suggest that wouldn’t be a suitable use. Additionally, the council noted that there aren’t viable alternative sites for the solar farm, which, therefore, must be built on the landfill site or else potentially set back the city’s climate goals.

If Howells can’t turn the landfill into a park, he suggested that he could simply clear it out so that it can be used as a landfill again.

But the Newport council does not appear to be entertaining his offer, the same way the council seemingly easily rejected his prior offer to share his bitcoin profits if granted access to dig up the landfill. When asked about Howells’ most recent offer, a council spokesperson directed The Times to a 2023 statement holding strong to the city’s claims that Howells gave up ownership of the bitcoins the moment the hard drive hit the landfill and his plans for excavation would come at “a prohibitively high cost.”

“We have been very clear and consistent in our responses that we cannot assist Mr. Howells in this matter,” the spokesperson said. “Our position has not changed.”

Howells insists his plan is “logical”

But Howells told The Guardian that it was “quite a surprise” to learn the city planned to close the landfill, reportedly in the 2025–26 financial year. This wasn’t disclosed in the court battle, he said, where the council claimed that “closing the landfill” to allow his search “would have a huge detrimental impact on the people of Newport.”

“I expected it would be closed in the coming years because it’s 80–90 percent full—but didn’t expect its closure so soon,” Howells told The Guardian. “If Newport city council would be willing, I would potentially be interested in purchasing the landfill site ‘as is’ and have discussed this option with investment partners and it is something that is very much on the table.”

After Trump killed a report on nature, researchers push ahead with release

But one word in the federal register notice describing key principles of the nature report—”inclusive”—may have triggered Trump’s decision to end it. Christopher Schell, a lead author of a chapter called “Nature and Equity in the US,” told The Times that his chapter’s focus on environmental justice may have made the project an easy target for Trump.

On day one of his administration, Trump issued executive orders rescinding Biden-era priorities and ending several environmental justice and equity initiatives in government. According to an analysis from two experts at Harvard’s energy and environmental law program, Carrie Jenks and Sara Dewey, Trump claimed, “without explanation,” that the Biden initiatives violate “longstanding Federal civil-rights laws” and “threaten the safety of American men, women, and children.”

Now “federal agencies no longer have a mandate, unless required under separate rules, to consider how their actions will disproportionately harm low-income communities, communities of color, and other vulnerable populations,” the Harvard researchers warned.

Trump contradictions in environmental orders

Grist reported on the scramble to salvage a wide range of Trump-purged climate data like the National Nature Assessment that could help protect vulnerable communities by remaining in the public sphere. That report noted that climate data access was similarly lost during Trump’s prior administration, when “as much as 20 percent of the EPA’s website became inaccessible to the public” and the government’s “use of the term ‘climate change’ decreased by more than a third.”

But even if some members of the public remain jaded from Trump’s prior administration, researchers working on the nature report told The Times that their biggest concern in moving forward with the report is that the general public views government studies as more authoritative than independent studies. The fear is that even if the report is eventually published, its impact could be watered down without the government’s involvement or endorsement.

As fires spread with alarming speed through the Pacific Palisades region of Los Angeles Tuesday, Jan. 7, a local TV news crew recorded a mountain lion trailed by two young cubs running through a neighborhood north of the fire. The three lions were about three-quarters of a mile from the nearest open space. Another TV crew captured video of a disoriented, seemingly orphaned fawn trotting down the middle of a street near the Eaton Fire in Altadena, her fur appearing singed, her gait unsteady.

Firefighters are still struggling to contain fires in Los Angeles County that have so far destroyed thousands of homes and other structures and left more than two dozen people dead. Fires and the notorious Santa Ana winds that fuel their spread are a natural part of this chaparral landscape.

But a warming world is supercharging these fires, experts say. Climate change is causing rapid shifts between very wet years that accelerate the growth of scrubland grasses and brush, leading to what’s known as “excessive fuel loading,” that hotter summers and drier falls and winters turn into easily ignited tinderbox conditions. The area where the fires are burning had “the singularly driest October through early January period we have on record,” said climate scientist Daniel Swain during an online briefing last week.

It’s too soon to know the toll these fires have taken on wildlife, particularly wide-ranging carnivores like mountain lions. But biologists worry that the growing severity and frequency of fires is outpacing wildlife’s ability to adapt.

State wildlife officials don’t want people to provide food or water for wild animals, because it can alter their behavior, spread disease, and cause other unintended effects. What wildlife need right now, they say, is to reach safe habitat as fast as they can.

Wildlife living at the interface of urban development already face many challenges, and now these fires have deprived them of critical resources, said Beth Pratt, California National Wildlife Federation regional executive director. Animals that escaped the flames have lost shelter, water, and food sources, all the things they need to survive, she said. The fires are even wiping out many of the plants butterflies and other pollinators need to feed and reproduce, she noted.

Connecting isolated patches of habitat with interventions like wildlife crossings is critical not only for building fire resilience, Pratt said, but also for protecting biodiversity long term.

Mountain lions and other wildlife adapted to the wildfires that shaped the Southern California landscape over thousands of years.

Many animals respond to cues that act as early warning signs of fire, using different strategies to avoid flames after seeing or smelling smoke plumes or hearing tree limbs crackle as they burn. Large animals, like mountain lions and deer, tend to run away from advancing flames while smaller species may try to take cover.

But now, with major fires happening every year around highly urbanized areas like LA, they can’t simply move to a nearby open space.

Daniel Blumstein, a professor of ecology and evolutionary biology at the University of California, Los Angeles, and others have exposed animals to fire-related sensory cues in experiments to study their responses.

“A variety of different species, including lizards, hear or smell these cues and modify their behavior and take defensive action to try to survive,” said Blumstein.

If you’re a lizard or small mammal, he said, getting underground in something like a burrow probably protects you from fire burning above you.

“But the magnitude and rapidity of these sorts of fires, and the rapidity of these fires particularly, you can’t do anything,” said Blumstein. “I expect lots of wildlife has been killed by this fire, because it just moved so fast.”

Helping wildlife during emergencies

Wildlife experts urge California residents not to provide food or water for wildlife during emergencies like the LA fires. Attracting wildlife to urban areas by providing food and water can have several unintended negative consequences.

Fire events often leave many concerned citizens wondering what they can do to help displaced or injured wildlife, said California Department of Fish and Wildlife spokesperson Krysten Kellum. The agency appreciates people wanting to help wild animals in California, she said, offering the following recommendations to best help wildlife during emergencies:

Please DO NOT provide food or water to wildlife. While this may seem well intentioned, the most critical need of wildlife during and after a wildfire is for them to find their way to safe habitat as quickly as possible. Stopping for food or water in fire zones and residential areas poses risks to them and you. Finding food and water in a specific location even one time can permanently alter an animal’s behavior. Wildlife quickly learns that the reward of receiving handouts from humans outweighs their fears of being around people. This often leads to a cycle of human-wildlife conflicts, which can easily be avoided.

CDFW also advises leaving wild animal rescue to trained professionals. If you find an orphaned, sick, or injured wild animal after a fire event, report the sighting to local CDFW staff by emailing details to R5WildlifeReport@wildlife.ca.gov. You can also contact a licensed wildlife rehabilitator. For a list of licensed rehabilitators, visit the CDFW website.

Just as human defenses didn’t work against flames fanned by winds moving 100 miles an hour, he said, “things animals might do might not be effective for something traveling so fast.”

Tuesday night, Jan. 7, Blumstein saw the Eaton Fire burning in the mountains around Altadena, about 30 miles northeast of his home in the Santa Monica Mountains. When he woke up later in the night, he saw that the “whole mountain” was on fire.

“You can’t run away from that,” he said.

An evolutionary mismatch

The Los Angeles region is the biggest metropolitan area in North America inhabited by mountain lions. City living has not been kind to the big cats.

If they don’t die from eating prey loaded with rat poison, lions must navigate a landscape so fragmented by development they often try to cross some of the busiest freeways in the world, just to find food or a mate or to avoid a fight with resident males.

It’s a lethal choice. About 70 mountain lions are killed on California roads every year, according to the UC Davis Road Ecology Center. The Los Angeles region is a hotspot for such deaths.

“Roads are the highest source of mortality in our study area,” said Jeff Sikich, a wildlife biologist with the National Park Service who has been studying the impacts of urbanization and habitat fragmentation on mountain lions in and around the Santa Monica Mountains for more than two decades.

Sikich and his team track adults and kittens that they implant with tiny transmitters. In 2023, one of those transmitters told him a three-month-old kitten had been killed on a road that cuts through the Santa Monica Mountains.

The kittens caught on video following their mom near the Palisades Fire are probably about the same age.

Lions living in the Santa Monica Mountains are so isolated from potential mates by roads and development, Sikich and other researchers reported in 2022, they face a high risk of extinction from extremely low levels of genetic diversity.

“We don’t have many lions radio collared now, but there is one adult male that uses the eastern Santa Monica Mountains, where the Palisades Fire is,” Sikich said. “I located him on Monday outside the burn area, so he’s good.”

Most of the animals don’t have radio collars, though, so Sikich can’t say how they’re doing. But if they respond to these fires like they did to previous conflagrations, they’re likely to take risks searching for food and shelter that increase their chances of fatal encounters and—if these types of fires persist—extinction.

“We learned a lot after the Woolsey Fire that happened in 2018 and burned nearly half of the Santa Monica Mountains and three-quarters of the Simi Hills,” said Sikich.

Sikich and his team had 11 lions collared at the time and lost two in the Woolsey Fire. One of the cats “just couldn’t escape the flames,” Sikich said. A second casualty, tracked as P-64 (“P” is for puma), was a remarkably resourceful male nicknamed “the culvert cat” because he’d managed to safely navigate deadly roadways to connect three different mountain ranges within his home range.

The cat traversed a long, dark tunnel under Highway 101, used by more than 350,000 cars a day, to reach a small patch of habitat north of the Santa Monica Mountains. Then he used another tunnel, made for hikers and equestrians, to reach a much larger open space to the north. But when the fire broke out, he didn’t have time to reach these escape routes.

Sikich could see from P-64’s GPS collar that he was in the Simi Hills when the fire started. He began heading south, but ran smack into a developed area, which adult males do their best to avoid, even without the chaos of evacuations and fire engines.

“So he had two options,” Sikich said. “He could have entered the urban area or turned around and go back onto the burnt landscape, which he did.”

A few weeks later, Sikich got a mortality signal from P-64’s radio collar. “We didn’t know at the time, of course, but when we found him, he had burnt paws,” he said. “So he died from the effects of the fire.”

The cat was emaciated, with smoke-damaged lungs. His burnt paws hindered his ability to hunt. He likely starved to death.

When the team compared collared cats 15 months before and after the fire, they saw that the surviving cats avoided the burned areas. Lions need cover to hunt but the area was “just a moonscape,” Sikich said. The loss of that habitat forced the cats to take greater risks, likely to find food.

Mountain lions tend to be more active around dawn and dusk, but after the fire, collared cats were more active during the day. That meant they were more likely to run into people and cross roads and even busy freeways, Sikich and his team reported in a 2022 study.

On Dec. 3, 2018, National Park Service researchers discovered the remains of P-64, who survived the flames of the Woolsey Fire but died a few weeks later. The lion was emaciated and likely starved to death, unable to hunt with burnt paws.

“We expect animals, in the long run, to adapt to the environments in which they live,” said Blumstein, who contributed to the study. In California, they adapted to coastal chaparral fires but not to fires in a fragmented habitat dominated by development. And when animals adapt to something, there can be mismatches between what they see as attractive and what’s good for them, he explained.

“Historically, being attracted to dense vegetation might have been a good thing, but if the only dense vegetation left after a fire is around people’s houses, that may not be a good thing,” he said.

Two cats tracked after the fire died of rodenticide poisoning and another was killed by a vehicle.

The cats also traveled greater distances, which put young males at greater risk of running into older males defending their territory. The cat who died on the road was the first to successfully cross the 405 interstate, the busiest in the nation, from the Santa Monica Mountains into the Hollywood Hills. Sikich knew from remote cameras that an adult male had lived there for years. Then after the fire, surveillance footage from a camera in a gated community caught that dominant male chasing the young intruder up a tree, then toward the freeway.

“He tried to head back west but wasn’t lucky this time as he crossed the 405,” Sikich said.

Add climate change-fueled fires to the list of human activity that’s threatening the survival of Southern California’s mountain lions.

Counting on wildlife crossings

When the Woolsey Fire took out half of the open space in the Santa Monica Mountains, it placed considerable stress on animals from mountain lions to monarchs, said Pratt of the National Wildlife Federation. These massive fires underscore the urgent need to connect isolated patches of habitat to boost species’ ability to cope with other stressors, especially in an urban environment, she said.

Studies by Sikich and others’ demonstrated the critical need for a wildlife crossing across Highway 101 to connect protected habitat in the Santa Monica Mountains with habitat in the Simi Hills in the north. It was at a tunnel underneath the 101 connecting those two regions that Sikich first saw the “culvert cat,” the lion with burnt paws who perished in the Woolsey Fire.

More than 20 years of research highlights the importance of connectivity in these fire-prone areas, he said, so animals can safely get across the freeways around these urban areas.

Pratt helped raise awareness about the need for a wildlife crossing through the #SaveLACougars campaign. She also helped raise tens of millions of dollars to build the Wallis Annenberg Wildlife Crossing, aided by P-22, the mountain lion who became world-famous as the “Hollywood cat.” P-22 lived his life within an improbably small 8-square-mile home range in LA’s Griffith Park, after crossing two of the nation’s busiest freeways.

The crossing broke ground in 2022, the same year wildlife officials euthanized P-22, after they determined the 12-year-old cat was suffering from multiple serious injuries, likely from a vehicle strike, debilitating health problems, and rodenticide poisoning.

Wildlife crossing and connectivity projects don’t just address biodiversity collapse, they also boost fire and climate resilience, Pratt said, because they give animals options, whether to escape fire, drought, or roads.

Thinking of fire as something to fight is a losing battle, she said. “It’s something we have to coexist with. And I think that we are making investments that are trying to take out a reliance on fossil fuels so that the conditions for these fires are not so severe,” she said, referring to California’s targets to slash greenhouse gas emissions within the next 20 years.

Even with the inbreeding and lethal threats from cars and rat poison, Sikich sees reason to be hopeful for the Santa Monica lion population.

For one thing, he said, “we’re seeing reproduction,” pointing to the mom with kittens seen above the Palisades fire and new litters among the females his team is following. “And the amount of natural habitat we do have is great,” he said, with plenty of deer and cover for hunting. “That’s why we still have lions.”

Supreme Court lets Hawaii sue oil companies over climate change effects

On Monday, the Supreme Court declined to decide whether to block lawsuits that Honolulu filed to seek billions in damages from oil and gas companies over allegedly deceptive marketing campaigns that hid the effects of climate change.

Now those lawsuits can proceed, surely frustrating the fossil fuel industry, which felt that SCOTUS should have weighed in on this key “recurring question of extraordinary importance to the energy industry” raised in lawsuits seeking similarly high damages in several states, CBS News reported.

Defendants Sunoco and Shell, along with 15 other energy companies, had asked the court to intervene and stop the Hawaii lawsuits from proceeding. They had hoped to move the cases out of Hawaii state courts by arguing that interstate pollution is governed by federal law and the Clean Air Act.

The oil and gas companies continue to argue that greenhouse gas emissions “flow from billions of daily choices, over more than a century, by governments, companies, and individuals about what types of fuels to use, and how to use them.” Because of this, the companies believe Honolulu was wrong to demand damages based on the “cumulative effect of worldwide emissions leading to global climate change.”

“In these cases, state and local governments are attempting to assert control over the nation’s energy policies by holding energy companies liable for worldwide conduct in ways that starkly conflict with the policies and priorities of the federal government,” oil and gas companies unsuccessfully argued in their attempt to persuade SCOTUS to grant review. “That flouts this court’s precedents and basic principles of federalism, and the court should put a stop to it.”

Everyone agrees: 2024 the hottest year since the thermometer was invented


An exceptionally hot outlier, 2024 means the streak of hottest years goes to 11.

Over the last 24 hours or so, the major organizations that keep track of global temperatures have released figures for 2024, and all of them agree: 2024 was the warmest year yet recorded, joining 2023 as an unusual outlier in terms of how rapidly things heated up. At least two of the organizations, the European Union’s Copernicus and Berkeley Earth, place the year at about 1.6° C above pre-industrial temperatures, marking the first time that the Paris Agreement goal of limiting warming to 1.5° has been exceeded.

NASA and the National Oceanic and Atmospheric Administration both place the mark at slightly below 1.5° C over pre-industrial temperatures (as defined by the 1850–1900 average). However, that difference largely reflects the uncertainties in measuring temperatures during that period rather than disagreement over 2024.

It’s hot everywhere

2023 had set a temperature record largely due to a switch to El Niño conditions midway through the year, which made the second half of the year exceptionally hot. It takes some time for that heat to make its way from the ocean into the atmosphere, so the streak of warm months continued into 2024, even as the Pacific switched into its cooler La Niña mode.

While El Niños are regular events, this one had an outsized impact because it was accompanied by unusually warm temperatures outside the Pacific, including record high temperatures in the Atlantic and unusual warmth in the Indian Ocean. Land temperatures reflect this widespread warmth, with elevated temperatures on all continents. Berkeley Earth estimates that 104 countries registered 2024 as the warmest on record, meaning 3.3 billion people felt the hottest average temperatures they had ever experienced.

Different organizations use slightly different methods to calculate the global temperature and have different baselines. For example, Copernicus puts 2024 at 0.72° C above a baseline that will be familiar to many people since they were alive for it: 1991 to 2000. In contrast, NASA and NOAA use a baseline that covers the entirety of the last century, which is substantially cooler overall. Relative to that baseline, 2024 is 1.29° C warmer.

Lining up the baselines shows that these different services largely agree with each other, with most of the differences due to uncertainties in the measurements, with the rest accounted for by slightly different methods of handling things like areas with sparse data.

Describing the details of 2024, however, doesn’t really capture just how exceptional the warmth of the last two years has been. Starting in around 1970, there’s been a roughly linear increase in temperature driven by greenhouse gas emissions, despite many individual years that were warmer or cooler than the trend. The last two years have been extreme outliers from this trend. The last time there was a single comparable year to 2024 was back in the 1940s. The last time there were two consecutive years like this was in 1878.

“These were during the ‘Great Drought’ of 1875 to 1878, when it is estimated that around 50 million people died in India, China, and parts of Africa and South America,” the EU’s Copernicus service notes. Despite many climate-driven disasters, the world at least avoided a similar experience in 2023-24.

Berkeley Earth provides a slightly different way of looking at it, comparing each year since 1970 with the amount of warming we’d expect from the cumulative greenhouse gas emissions.

A graph showing a reddish wedge, growing from left to right. A black line traces the annual temperatures, which over near the top edge of the wedge until recent years.

Relative to the expected warming from greenhouse gasses, 2024 represents a large departure. Credit: Berkeley Earth

These show that, given year-to-year variations in the climate system, warming has closely tracked expectations over five decades. 2023 and 2024 mark a dramatic departure from that track, although it comes at the end of a decade where most years were above the trend line. Berkeley Earth estimates that there’s just a 1 in 100 chance of that occurring due to the climate’s internal variability.

Is this a new trend?

The big question is whether 2024 is an exception and we should expect things to fall back to the trend that’s dominated since the 1970s, or it marks a departure from the climate’s recent behavior. And that’s something we don’t have a great answer to.

If you take away the influence of recent greenhouse gas emissions and El Niño, you can focus on other potential factors. These include a slight increase expected due to the solar cycle approaching its maximum activity. But, beyond that, most of the other factors are uncertain. The Hunga Tonga eruption put lots of water vapor into the stratosphere, but the estimated effects range from slight warming to cooling equivalent to a strong La Niña. Reductions in pollution from shipping are expected to contribute to warming, but the amount is debated.

There is evidence that a decrease in cloud cover has allowed more sunlight to be absorbed by the Earth, contributing to the planet’s warming. But clouds are typically a response to other factors that influence the climate, such as the amount of water vapor in the atmosphere and the aerosols present to seed water droplets.

It’s possible that a factor that we missed is driving the changes in cloud cover or that 2024 just saw the chaotic nature of the atmosphere result in less cloud cover. Alternatively, we may have crossed a warming tipping point, where the warmth of the atmosphere makes cloud formation less likely. Knowing that will be critical going forward, but we simply don’t have a good answer right now.

Climate goals

There’s an equally unsatisfying answer to what this means for our chance of hitting climate goals. The stretch goal of the Paris Agreement is to limit warming to 1.5° C, because it leads to significantly less severe impacts than the primary, 2.0° target. That’s relative to pre-industrial temperatures, which are defined using the 1850–1900 period, the earliest time where temperature records allow a reconstruction of the global temperature.

Unfortunately, all the organizations that handle global temperatures have some differences in the analysis methods and data used. Given recent data, these differences result in very small divergences in the estimated global temperatures. But with the far larger uncertainties in the 1850–1900 data, they tend to diverge more dramatically. As a result, each organization has a different baseline, and different anomalies relative to that.

As a result, Berkeley Earth registers 2024 as being 1.62° C above preindustrial temperatures, and Copernicus 1.60° C. In contrast, NASA and NOAA place it just under 1.5° C (1.47° and 1.46°, respectively). NASA’s Gavin Schmidt said this is “almost entirely due to the [sea surface temperature] data set being used” in constructing the temperature record.

There is, however, consensus that this isn’t especially meaningful on its own. There’s a good chance that temperatures will drop below the 1.5° mark on all the data sets within the next few years. We’ll want to see temperatures consistently exceed that mark for over a decade before we consider that we’ve passed the milestone.

That said, given that carbon emissions have barely budged in recent years, there’s little doubt that we will eventually end up clearly passing that limit (Berkeley Earth is essentially treating it as exceeded already). But there’s widespread agreement that each increment between 1.5° and 2.0° will likely increase the consequences of climate change, and any continuing emissions will make it harder to bring things back under that target in the future through methods like carbon capture and storage.

So, while we may have committed ourselves to exceed one of our major climate targets, that shouldn’t be viewed as a reason to stop trying to limit greenhouse gas emissions.

study:-warming-has-accelerated-due-to-the-earth-absorbing-more-sunlight

Study: Warming has accelerated due to the Earth absorbing more sunlight

The concept of an atmospheric energy imbalance is pretty straightforward: We can measure both the amount of energy the Earth receives from the Sun and how much energy it radiates back into space. Any difference between the two results in a net energy imbalance that’s either absorbed by or extracted from the ocean/atmosphere system. And we’ve been tracking it via satellite for a while now as rising greenhouse gas levels have gradually increased the imbalance.

But greenhouse gases aren’t the only thing having an effect. For example, the imbalance has also increased in the Arctic due to the loss of snow cover and retreat of sea ice. The dark ground and ocean absorb more solar energy compared to the white material that had previously been exposed to the sunlight. Not all of this is felt directly, however, as a lot of the areas where it’s happening are frequently covered by clouds.

Nevertheless, the loss of snow and ice has caused the Earth’s reflectivity, termed its albedo, to decline since the 1970s, enhancing the warming a bit.

Vanishing clouds

The new paper finds that the energy imbalance set a new high in 2023, with a record amount of energy being absorbed by the ocean/atmosphere system. This wasn’t accompanied by a drop in infrared emissions from the Earth, suggesting it wasn’t due to greenhouse gases, which trap heat by absorbing this radiation. Instead, it seems to be due to decreased reflection of incoming sunlight by the Earth.

While there was a general trend in that direction, the planet set a new record low for albedo in 2023. Using two different data sets, the teams identify the areas most effected by this, and they’re not at the poles, indicating loss of snow and ice are unlikely to be the cause. Instead, the key contributor appears to be the loss of low-level clouds. “The cloud-related albedo reduction is apparently largely due to a pronounced decline of low-level clouds over the northern mid-latitude and tropical oceans, in particular the Atlantic,” the researchers say.

Seagrass is fantastic at carbon capture—and it’s at risk of extinction


An underwater gardening experiment along the East Coast aims at restoration.

In late September, seagrass ecologist Alyssa Novak pulled on her neoprene wetsuit, pressed her snorkel mask against her face, and jumped off an oyster farming boat into the shallow waters of Pleasant Bay, an estuary in the Cape Cod National Seashore in Massachusetts. Through her mask she gazed toward the sandy seabed, about 3 feet below the surface at low tide, where she was about to plant an experimental underwater garden of eelgrass.

Naturally occurring meadows of eelgrass—the most common type of seagrass found along the East Coast of the United States—are vanishing. Like seagrasses around the world, they have been plagued for decades by dredging, disease, and nutrient pollution from wastewater and agricultural runoff. The nutrient overloads have fueled algal blooms and clouded coastal waters with sediments, blocking out sunlight the marine plants need to make food through photosynthesis and suffocating them.

The United Nations Environment Program reports more than 20 of the world’s 72 seagrass species are on the decline. As a result, an estimated 7 percent of these habitats are lost each year.

In the western Atlantic, some eelgrass meadows have been reduced by more than 90 percent in the last 100 years, according to The Nature Conservancy, an environmental nonprofit that works to protect lands and waters around the world.

Now, rising sea surface temperatures caused by global warming are pushing the plant to the brink of extinction. Novak, a research assistant professor at Boston University who has studied eelgrass in New England for more than a decade, and a multidisciplinary team of scientists in different states are trying their best to make sure this does not become reality.

Together, they are working to restore eelgrass populations in coastal parks from Maine to North Carolina using a novel approach that has never been tried before with a marine plant: assisted migration.

“We’re trying to identify thermo-tolerant individuals up and down the East Coast and try to move them into areas where the populations are stressed by increases in sea surface temperature, so that we can give those populations a chance of surviving into the future,” Novak said.

Typically, eelgrass thrives in water temperatures between 60° and 68° Fahrenheit, according to Novak. In the last 20 years, sea surface temperatures in the Northeast have warmed faster than the global ocean and exceeded that safe range, mostly due to human activity like burning fossil fuels, according to NOAA Fisheries, a federal agency charged with managing and protecting marine resources in the US.

Around 77° Fahrenheit the plants become stressed and struggle to photosynthesize, said Novak. Around 82° they begin to expire. “That’s when the plants no longer can handle the heat stress, and they end up dying,” she said. And it’s getting hotter.

In recent years, she said, water temperatures along the East Coast have surpassed 82° during peak summer months. By 2050, they are expected to increase in the Northeast by two degrees, she said.

The common garden experiment

Anticipating the deadly forecast for eelgrass, The Nature Conservancy brought together a group of scientists in 2022 to figure out how they might change the plant’s trajectory. Together, the experts on seagrasses, corals, agriculture, forestry, and plant genetics explored options based on what had been done to address the effects of climate change on other ecosystems.

“We wanted to figure out what the solutions were that different groups had come up with, and from those, which ones might apply to the seagrass world,” said Boze Hancock, senior marine restoration scientist with The Nature Conservancy’s global oceans team.

Prolonged marine heatwaves and coral disease have prompted some scientists to experiment with cross-breeding and replanting heat-resistant corals in warming waters, for example. In some cases they have removed whole coral colonies from their natural habitat to preserve their genetics in land-based biobanks.

One of the workshop invitees, biologist Thomas Whitham, shared with the group how he’s used a scientific research tool called the “common garden experiment” to restore deciduous Fremont cottonwood forests that have been dying off in Arizona due to rising temperatures and drought.

The experiments involve collecting plants from different locations and moving them to designated locations to observe how they respond to new environmental conditions. In the case of Fremont cottonwoods, Whitham said the technique has proven vital to identifying trees with specific genetic traits that make them more heat and drought resilient. Cuttings from these trees are now being planted in areas where less resilient trees died off to restore the species in a process known as “assisted migration.”

“We’ve planted many thousands, tens of thousands, of trees using this common garden approach,” said Whitham, a Regents’ professor in the department of biological sciences at Northern Arizona University. It could work for eelgrass too, he told the group.

They could collect seeds from eelgrass populations in the south and plant them in cooler northern waters alongside local seeds and, in effect, identify plants that have a propensity to thrive in warmer temperatures.

Workshop participants were eager to try, said attendee Jonathan Lefcheck, a research ​scientist at the University of Maryland Center for Environmental Science who has studied seagrasses in the Chesapeake Bay for more than 15 years. “If we do nothing, it’s likely that seagrass—eelgrass—will be extirpated all the way up to New York in the next 50 years,” he said. And with it, all the services it provides to wildlife and humans.

Underwater forests

Eelgrass provides critical habitat for hundreds of species.

“It’s the forest under the water in the estuaries,” said Bradley Peterson, a professor of marine science at Stony Brook University’s School of Marine and Atmospheric Sciences who helped initiate the workshops in collaboration with The Nature Conservancy.

Scientists believe seagrasses evolved from terrestrial plants 70 to 100 millions years ago. “When they went into the marine world, they brought all the machinery they had with them for the terrestrial world, real seeds, real flowers, and real roots,” said Peterson, who is working to restore eelgrass near Long Island.

Its green grass blades, which can grow up to a couple feet long, offer food and shelter to horseshoe crabs, seahorses, and fish of all sizes that weave through its mazes. Little shrimp pollinate the plant’s flowers like “bees of the sea,” said Lefcheck. For bigger fish, “it’s this beautiful buffet,” he said. “You get this whole ecosystem that’s built up around this habitat that’s just sort of gently swaying there underneath the waves.”

In New England, eelgrass is vital for commercial scallop and oyster fisheries. Same for the Atlantic cod. “The cod industry is massive, so if you start losing that habitat, then your commercial fisheries go,” Novak said.

You also lose important coastline protection. Seagrass helps prevent erosion and buffers shorelines from flooding and storm surge. It can reduce wave energy by 50 percent, according to Novak. It also improves water quality and clarity by filtering pollutants and storing excess nutrients, reducing the prevalence of bacteria that can cause coral disease or contaminate seafood. “If you lose eelgrass, you’re going to have dirtier waters,” she said. Global warming could also be exacerbated.

Seagrasses sequester up to 18 percent of carbon stored in the ocean, capturing it 35 times faster than tropical rainforests, according to the World Wide Fund for Nature. The New York Department of State, Office of Planning, Development and Community Infrastructure reports each acre of seagrass can potentially sequester the same amount of carbon emitted by a car driving nearly 4,000 miles each year. But when this unique marine habitat is destroyed, carbon that has been stored in the plant’s roots and sediments—sometimes for thousands of years—is released back into the atmosphere, said Novak.

Sharing seeds

To have a chance at repopulating eelgrass along the East Coast, scientists like Novak, Peterson, and Lefcheck realized they would have to share information and collaborate across state borders—something to which academics are not always accustomed, according to Novak.

“It’s not our nature to share information that freely, because we’re supposed to be focusing on publishing,” she said. But the crisis at hand had inspired a change in the status quo. “We’re a team,” she said. “We’re about saving the eelgrass and doing what’s best for this ecosystem.”

They call the regional effort HEAT (Helping Eelgrass Adapt to Temperature). In the last year, participants have been working together to identify the best possible sites for planting common gardens along the East Coast. So far, they’ve homed in on several national parks: the Cape Cod National Seashore, Fire Island National Seashore in New York, Assateague Island in Maryland and Cape Hatteras and Cape Lookout national seashores in North Carolina.

“We want to set ourselves up for some success and use the information we have about these parks to guide our decision-making and make sure we’re putting these in places where they might have enough light, where they won’t have as many human impacts,” said Lefcheck.

They’ve also begun collecting and sharing seeds. “We’re sharing actual plants with each other for genomics, and then we’re also sharing seeds with each other for doing our common gardens and for experiments,” Novak said.

This past year Novak sent samples of eelgrass plants collected in Massachusetts to the University of North Carolina Wilmington for Stephanie Kamel, a professor in the department of biology and marine biology at the university, to analyze. Kamel is looking for plants that have specific genetic markers that might make them more resilient to challenging environmental conditions like warmer temperatures and lower light, which is becoming an increasing problem as sea levels rise due to global warming pushing the plants deeper underwater. Currently, she’s analyzing the DNA of 800 eelgrass plants from 60 meadows along the East Coast. “We’re going to have this sort of unprecedented level of detail about genomic variation across the range of Zostera (eelgrass),” said Kamel.

This information could be used to help collaborators figure out which seeds they should plant in different locations based on their specific environmental conditions and challenges, said Jessie Jarvis, a seagrass ecologist and professor who works with Kamel at the University of North Carolina Wilmington.

“It’s almost like a dating app for seagrass,” Jarvis said. “You could be a little bit smarter about picking your source populations to match what your restoration needs are, rather than just kind of throwing seeds from everywhere and hoping that something works.”

In the meantime, though, common gardening remains the most practical tool to figure out which plants from which locations may be the best stock for future eelgrass populations. This past year Kamel and Jarvis piloted a common garden experiment in North Carolina and Virginia.

“We took those seeds from what we thought were, quote, unquote, good sources (in North Carolina), and we actually moved them to Virginia. And then we took some Virginia seeds and moved them to North Carolina to actually see what would happen in terms of growth,” said Kamel. While it’s still too early to draw firm conclusions from the experiment, Kamel said preliminary results seem promising. “There are really encouraging signs that we have been able to find some genomic changes associated with temperature resilience,” she said.

Others are following suit. This past spring, Novak and Peterson harvested reproductive eelgrass shoots filled with seeds while snorkeling and scuba diving in Acadia National Park in Maine and Cape Cod, Nantucket, Gloucester in Massachusetts. Lefcheck harvested in Maryland. “What we do is harvest them before they’ve released the seeds, because the seeds are tiny, like the size of a pinhead,” Lefcheck said. The shoots are then held in saltwater tanks until the seeds drop and can easily be collected and stored until it’s time to plant them.

It’s best to wait to plant eelgrass in the early fall, after most of the late summer storms have passed, according to Novak, who spent several days planting seeds in Pleasant Bay and nearby East Harbor this September with a team including a biologist from the National Park Service and a representative from the Mashpee Wampanoag Tribe. To get to the Pleasant Bay site, they motored out onto the water on an oyster farming boat. “The oyster farmers are interested in the project because our site is adjacent to their farm and they recognize that healthy beds are important to sustaining their livelihood,” Novak said.

Before getting wet, Novak and her team ran through their gardening plan. “We do dry runs on land, just to get everybody organized, but it’s not the same when you get into the water,” she said. “You’re trying to hold things underwater. You can’t see as well, even if you have a mask on.”

They would establish two 25-meter transect lines and then plant seeds from different donor sites in New York and Massachusetts. Nantucket was one of them. “We knew conditions were warmer at that particular site, so we said, let’s, let’s test them at Cape Cod,” she said.

Up to 500 seeds from each location would be planted by releasing them into the water column from a test tube or dropping tea bags filled with the seeds that would meander their way down to the seabed into 1-meter plots.

It was a slow process, Novak said, requiring hyper organization to make sure it’s clear which seeds have been planted where so that they can be monitored. In January, she will return to the sites to see if the plants are germinating. Then in the spring she’ll really be able to measure growth and compare how the different plants are faring in comparison to one another. “By next summer, we should have genomics for all of our populations, so that should really be guiding our efforts at that point,” she said.
