And it involves dumping 9,000 tons of fancy sand off the North Carolina coast.
When visitors flock to the beach this summer in Duck, North Carolina, a small, 6-mile long town on the Outer Banks, they may catch a glimpse of a climate experiment happening among the waves.
About 1,500 feet offshore, a company called Vesta will be pouring 9,000 tons of sand into the sea and watching carefully to see what happens next. This finely crushed rock will not be of the typical Outer Banks variety. Instead, it will consist of a mineral called olivine, which should enhance the ocean’s ability to absorb carbon from the atmosphere — and lock it away for thousands of years.
That the experiment can go ahead at all marks a milestone for ocean-based carbon removal, a category of climate solutions that prod the ocean into sucking up more CO2. A big obstacle for the field has been the lack of a legal framework for permitting real-world trials — U.S. laws governing the ocean weren’t written with the prospect of intentionally altering its chemistry to address an existential environmental crisis in mind. But after an 18-month interagency review process, Vesta is now the first company with a federal permit from the U.S. Army Corps of Engineers to deploy a stand-alone carbon removal test in U.S. waters.
Though 9,000 tons may sound like a lot, this is still a relatively small-scale pilot designed to assess how effective the olivine is in driving carbon removal, as well as observe any other changes in the environment and develop methods for tracking the movement of the sand in the water. These kinds of field trials are essential to establishing which marine carbon removal methods have potential and which don’t.
“We want to measure everything very carefully at this stage and make sure that we are fully understanding the safety profile and the carbon removal data from this project,” Tom Green, Vesta’s CEO, told me. But the company has big aspirations. If things go well, he said, maybe olivine could be used for beach nourishment projects all over the country, where sand is deposited along the shore to address erosion. “Imagine the carbon removal possibilities if we did that with olivine sand,” he said. “We could quickly become the largest technique for permanent carbon removal that's out there.”
Scientists generally agree that stopping global warming this century will require both reducing emissions and taking carbon out of the atmosphere. The sheer size of the ocean and its natural ability to store vast amounts of carbon make it an enticing place to look for solutions.
Dumping thousands of tons of non-native sand into the ocean may not sound like the most convincing option — especially since the ocean is already “experiencing unprecedented destabilizing changes through massive warming, acidification, deoxygenation, and a host of resulting effects,” according to an open letter published last year and signed by hundreds of scientists. However, despite this — or perhaps because of it — the letter called for accelerating research to find out whether any of the proposed ocean-based carbon removal methods, including releasing large quantities of ground olivine, are viable.
Olivine is an abundant mineral with special properties. When it comes into contact with seawater, it drives a chemical reaction that converts CO2 gas into more stable forms of carbon that can’t readily return to the atmosphere. This in turn creates a deficit of CO2 in the surface waters, which triggers the ocean to take up more from the atmosphere in order to maintain equilibrium.
Reactions like this are happening constantly in the ocean already, but on very slow timescales. Vesta’s innovation is to speed up the process by crushing and deploying olivine strategically where the wind and waves can most efficiently weather it away.

Olivine could address the harms of CO2 pollution in more ways than one. The ocean already absorbs about 30% of the carbon released into the atmosphere each year, which has made the water more acidic and less hospitable to many of its inhabitants. But when olivine triggers these reactions, it can act as a sort of antacid. This approach to carbon removal is also known as enhancing the ocean’s alkalinity and olivine is just one of a number of different ways to do it. Another company called Planetary is experimenting with adding a different mineral, magnesium hydroxide, to the ocean. Ebb Carbon, on the other hand, is sucking up seawater and running it through a membrane to increase its alkalinity, before returning it to the tides.
Both already have field trials up and running, but instead of trying to conduct stand-alone experiments in the open ocean they’ve hitched onto existing ocean dumping permits. Ebb, for example, has set up at the Pacific Northwest National Laboratory’s facility in Sequim, Washington, where it is releasing treated seawater into wastewater that flows into the bay. Similarly, Planetary is conducting pilot projects at the wastewater outflows of a water treatment facility and power plant in Canada. Other ocean carbon removal companies, such as Los Angeles-based Captura, have opted to move abroad for their early projects and avoid the U.S. permitting puzzle altogether.
Vesta went to Duck because it is among the most studied stretches of coastline in the country. The town is home to an Army Corps coastal field research center known for its long-term data set on the surrounding waters. “Few locations on the globe provide a better archive of wave, water, bathymetry and other forces that shape nearshore conditions,” according to the Army Corps’ website. (“Bathymetry” is the topography of the seafloor.) That means Vesta will be able to get a more accurate picture of any changes the olivine is responsible for.
When Drew Havens, the town manager in Duck, first heard about Vesta’s plans, he was skeptical. “You're dumping something into the ocean, people automatically go to, well, is it going to harm humans? Is it going to be harmful to wildlife or other living organisms?” he told me.
Though some in the town are still nervous, Havens said he has become more comfortable with the idea as the project has been rigorously reviewed by environmental protection regulators at the federal and state level. Vesta’s scientists also engaged with the town council, did an open house for members of the public, and have generally invited questions and open dialogue.
Just because regulators have determined that the risks of this pilot project are low, however, doesn’t mean using olivine for carbon removal is risk-free. For one, the rock has to be mined — in this case, from a quarry in Norway, although it is also found in the U.S. — and transported to the project site. That’s likely to produce some environmental impacts, though the company estimates that the project will ultimately remove about 10 times more CO2 from the atmosphere than the emissions associated with running the experiment, including the mining and shipping of olivine.
But the biggest risk with mined olivine is that it contains nickel, said Jaime Palter, an associate professor of oceanography at the University of Rhode Island who has no affiliation with Vesta. Nickel can act as both a nutrient and a toxin for phytoplankton, she told me, so it's important to study whether putting olivine in the ocean will result in adverse effects.
Vesta has been closely examining that possibility. In fact, the project in Duck will be the company’s second U.S. field trial. In the summer of 2022, Vesta got permission from the town of Southampton in Long Island to spread olivine on the beach as part of a larger sand replenishment project that was already in the works. Vesta’s scientists worked with local academic partners at Cornell, SUNY Stony Brook, and Hamilton College to do extensive monitoring both before and after the sand was placed, collecting data on more than 20 indicators of the effects on the water, sediment, and ecology.
The company has since published two annual reports on the project. It is still awaiting analysis of many of the samples, but so far, the results have been promising, Green said. There has been no sign of trace metal accumulation in Eastern Oysters, a species known to accumulate pollutants from their environment, for instance. There was also no significant difference in water quality between control areas and the sites with olivine, and trace metal concentrations were below the relevant EPA water quality guidelines. The area’s benthic macrofauna — critters like clams and small crustaceans that live on or near the seafloor — were as abundant and various as before.
Notably, the tests also showed evidence of an increase in alkalinity in the waters of the olivine-treated area, which is the key reaction that leads to carbon removal. But Green said there’s more work to be done in terms of calculating where and when removal may have happened.
There’s also more work to be done to understand the effects of olivine in different environments, which brings us back to Duck. There, it will be deposited in 25-foot deep water instead of on the beach, helping Vesta to further refine its data and measurement methods. The plan is to continue testing and collecting data at the site for at least two years. The company declined to comment on the budget for the project. Vesta is funded primarily by venture capital investors but also raises money for research through an affiliated nonprofit.
Vesta may have been the first to get a federal permit to run a marine carbon removal test, but it definitely won’t be the last. Nikhil Neelakantan, a senior project manager at Ocean Visions, which is a nonprofit that advocates for ocean-based climate solutions, told me there are a number of other domestic projects in the pipeline, including more than a dozen government-funded research projects. The White House also recently set up a marine carbon removal fast track action committee with the mandate to create recommendations for policy, permitting, and regulatory standards for both research and implementation.
Neelakantan said there is work to do on clarifying the role of different agencies in regulating ocean carbon removal, and which laws apply to each method.
“This is an early first step, and it's exciting to see that it's finally going to come to fruition,” he said, of Vesta’s project in Duck. “I think there's momentum with this federal task force. It's going to be the first of many others that will happen soon.”

A leaked internal memo reveals why the environmental group adopted President Trump’s new name.
The Nature Conservancy, an environmental nonprofit, was told by the National Oceanic and Atmospheric Administration it had to rename a major conservation program as the “Gulf of America” or else lose federal funding, according to a leaked internal memo reviewed by Heatmap News.
For the last week, the Nature Conservancy has been pilloried by figures in the climate and environmentalist community for changing the name of its conservation program in the Gulf of Mexico region to being a “Gulf of America” restoration program, brandishing what President Donald Trump declared on his first day in office would be the new official U.S. term for the body of water. Trump’s new name has become a First Amendment firestorm as news organizations find themselves split on whether to adopt the term and the White House is punishing outlets — including the Associated Press — for continuing to use the Gulf of Mexico.
We can now exclusively reveal why the Nature Conservancy adopted this fresh Trump branding: They were allegedly pressured into it.
Jennifer Morris, CEO of the Nature Conservancy, sent an email to all staff at the organization this morning stating that the organization’s conservation program in the Gulf of Mexico was renamed to Gulf of America “after receiving clear directives from a federal agency.” “Please know that we did not make this decision lightly,” Morris wrote. Attached to the email was staff guidance claiming the nonprofit “received specific direction from NOAA that we must change all references to the new nomenclature in association with our NOAA funded work in the Gulf.”
“For example, all maps, reports, and other deliverables must use ‘Gulf of America,’ the memo stated. “We have at least $156 million in active federal grants in the region, including $45 million from NOAA alone.’ Federal funding makes up most of the organization’s work in the Gulf of Mexico, according to the memo.
In addition, the Nature Conservancy has “been advised that new proposals in the Gulf for US federal grants must conform” to Trump’s executive order adopting “Gulf of America” as the official U.S. name for that body of water, the memo stated. State governors in the Gulf region in charge of “disseminating” remaining BP oil spill recovery funds have “followed suit in support of these nomenclature changes” and there is fear a “failure to adjust” could also “jeopardize” state funding.
“Ultimately, this decision was made after reviewing all the facts and looking at what the organization felt was best to ensure we can continue our conservation programs and support our teams on the ground,” the memo stated.
Historically, NOAA has been more insulated than other agencies from political pressures like this, which has helped it maintain a global reputation as a world-class scientific meteorological body.
This ordeal, however, echoes the one other time Trump seemed to put his thumb on NOAA’s scales — an incident best known as Sharpiegate. In 2019 Trump incorrectly proclaimed Hurricane Dorian was going to hit Alabama. He went so far as to draw on a giant map with a Sharpie in the White House to show his guestimated pathway for the storm. After the NOAA office in Alabama publicly sought to reassure residents that, no, a hurricane wasn’t on the way, Trump officials pressured NOAA into backing the president, leading to the agency issuing an unsigned statement backing the claim. An inspector general report – which Trump officials reportedly sought to obstruct from seeing the light of day – ultimately found the NOAA statement violated its scientific integrity policy.
If the Gulf of America is the beginning of NOAA subservience, I’m nervous to see what happens when Trump’s version of the agency – which any day now is expected to undergo mass layoffs – pivots to climate change and renewable energy.
The Nature Conservancy did not immediately respond to a request for comment. “We can find no evidence of that, so far,” NOAA spokesman Scott Smullen said.
President Donald Trump is going to be talking rocks with his Ukrainian counterpart Volodymyr Zelenskyy during their Friday meeting in Washington, D.C., where they will sign a “very big agreement,” Trump said Wednesday.
As the Trump administration has ramped up talks to end the war in Ukraine, shift America’s strategic priorities away from Europe, and build a new relationship with Russia, it has also become intensely interested in Ukraine’s supposed mineral wealth, with Ukrainian and American negotiators working on a deal to create an investment fund for the country’s reconstruction that would be partially funded by developing the country’s mineral resources.
But exactly what minerals are in Ukraine and if they’re economically viable to extract is a matter of contention.
So-called critical minerals and rare earths have a way of finding themselves in geopolitical hotspots. This is because they’re not particularly rare, but the immense capital required to cost effectively find them, mine them, and process them is.
“A lot of countries have natural resources. We don’t mine everything that exists underground. We look for projects that are economically competitive,” Gracelin Baskaran, director of the critical minerals security program at the Center for Strategic and International Studies, told me.
Baskaran pointed out, it was precisely Russia’s full-scale invasion of Ukraine that kicked the United States’ interest in building up supplies of critical minerals and rare earths outside of China — which dominates the industry — into overdrive.
“It was a fortuitous moment in that way for Ukraine’s resources, because they weren’t necessarily being mined before,” she said.
And Ukraine has done its best to promote and take advantage of its mineral resources, even if there’s some ambiguity about what exactly they are, and if they can be profitably extracted at scale.
While often conflated, critical minerals and rare earths are distinct. The so-called “rare earths” are 17 similar elements, which the U.S. Geological Survey explicitly says are “relatively abundant,” like scandium and yttrium. Critical minerals are a more amorphous group, with the USGS listing out 50 (including the rare earths) as well as commonly known minerals like titanium, nickel, lithium, tin, and graphite, with uses in batteries, alloys, semiconductors, and other high value energy, defense, and technology applications.
When countries are desperate for outside assistance or their patrons are desperate to see some return on their “investments” in military and foreign aid,as Bloomberg’s Javier Blas has pointed out, the minerals tend to show up — just look at the “$1 trillion in untapped mineral deposits” the United States identified in Afghanistan in 2010. Ten years later when the USGS looked at Afghanistan’s mineral industries, the rare earths remained untapped and instead the country was largely exporting talc and crushed marble to its neighbors.
Ukrainians have been eager to show there are economically viable and valuable minerals in the country, including a claim by one Ukrainian official in early 2022 that “about 5% of all the world’s ‘critical raw materials’ are located in Ukraine,” while a pair of Ukrainian researchers claimed there was 500,000 tons of unmined lithium oxide resources. More recently the country has claimed to have rare earths, and that President Trump has taken a special interest in.
Many industry experts doubt there’s any significant reserves of rare earths in the country, with the exception of scandium, which is used in aluminum alloys and fuel cells. Ukraine does have a significant mining industry and has produced substantial amounts of iron ore and manganese, along with reserves of graphite, titanium, cobalt, and uranium, many of which are those so-called “critical minerals” with uses for energy and defense.
“There do not appear to be hardly any economically viable rare earths in the country – that was largely a misuse of a term someone heard,” Morgan Bazillian, director of the Payne Institute and a public policy professor at the Colorado School of Mines, told me in an email.
Blas has documented a game of telephone whereby rare earths and critical minerals are conflated to make it seem like the former exists in abundance underneath Ukraine. Despite the doubts, President Trump said on Wednesday during his cabinet meeting “we’ll be really partnering with Ukraine, [in] terms of rare earth. We very much need rare earth. They have great rare earth.”
While there’s disagreement about exactly what Ukraine has to offer in terms of minerals, the interest in building up supplies of minerals is part and parcel of what is now a bipartisan priority to build up supplies and the ability to process and refine minerals used for a variety of defense, industrial, and energy applications.
To the extent the United States is able to jumpstart any new mineral operations in postwar Ukraine, it would require first repairing the country’s greatly damaged infrastructure, which has been wrecked by the very conflict that has spiked interest in the country’s mineral sector.
“Their infrastructure is decimated. Rebuilding it will be the priority, getting industry moving again will take time – including from basic services like electricity,” Bazillian told me.
And after that, much basic work needs to be done before any mining can happen, like an updated geological survey of the country, which hasn’t been done since the country was part of the Soviet Union. And all that’s before starting the process for opening a mine, something that on average takes 18 years to do.
“You need to have a geological mapping. You need to identify investors who want to go in. You need to build infrastructure,” Baskaran said.
“Ukraine has undeveloped or untapped potential that could be utilized. And the question is whether that untapped potential is economically viable, and we don’t know yet.”
Current conditions: Firefighters contained a blaze in South Africa’s Table Mountain National Park that was creeping towards Cape Town • Moroccans are being asked not to slaughter sheep during Eid al-Adha this year because ongoing drought has caused a drop in herd numbers • Most of the U.S. will see “well above-average” temperatures through the end of this week.
The House voted yesterday to repeal a Biden-era fee on methane emissions generated by oil and gas operations. The Senate is likely to follow suit with a vote as soon as today. The rule, which was only finalized in November, charges producers per metric ton of excess methane released, and provides grants for infrastructure improvements to prevent leaks. Methane is a potent greenhouse gas responsible for roughly one third of the global temperature rise since the pre-industrial era. The EPA estimated the policy would prevent 1.2 million metric tons of methane from entering the atmosphere, which is roughly equivalent to taking nearly 8 million gas-powered cars off the road for a year. Congress will also vote this week on a measure repealing another recently implemented rule regarding efficiency standards for tankless gas water heaters.
President Trump said yesterday that EPA Administrator Lee Zeldin is aiming to cut 65% of the agency’s workforce. The EPA currently has about 15,000 employees, and E&E News reported that such a cut “would put the agency close to the numbers it had when it was created by President Richard Nixon.” According toReuters, the news came as a surprise to EPA union leaders. “Mr. Zeldin stated during his confirmation testimony that he pledged to enthusiastically uphold the EPA’s mission,” said Joyce Howell, executive vice president of AFGE Council 238 representing EPA employees. “So which is it? Upholding the EPA mission or imposing a reduction in force that makes upholding the EPA mission an impossibility?”
BP confirmed it will cut its investments in renewables and shift its strategy back to ramping up fossil fuel production. The radical shift represents “a major break from five years in which BP was the oil industry’s most ardent pursuer of net zero emissions and the transition to clean energy,” reportedBloomberg. BP had planned to have 50 gigawatts of renewable generation capacity by 2030 and cut oil and gas production by 40%, but CEO Murray Auchincloss said the company’s “optimism for a fast transition was misplaced.” Here is some early reaction and analysis:
New research suggests the Atlantic Meridional Overturning Circulation (AMOC) is not likely to fully collapse any time soon, but it could weaken significantly. As Heatmap’s Jeva Lange explained recently, AMOC is a current system sometimes described as the oceanic conveyor belt responsible for influencing the climate of the Northern Hemisphere. Its full collapse, triggered by rising temperatures and Arctic meltwater – would cause dramatic cooling across Europe, and scientists have been debating the likelihood of such an event for years. A recent paper predicted it could happen even within the next three decades. This new analysis from the UK’s Met Office used 34 climate models to test future warming scenarios and concluded that AMOC would still keep moving through 2100. But it also showed the current could slow down significantly, which would still have serious side effects like changing rain patterns, disrupting ocean ecosystems, and rising sea levels.
A study out this week finds that exposure to extreme heat makes older people age faster. Researchers from USC examined blood samples from 3,600 individuals aged 56 or older, looking specifically at markers indicating biological age, which is “a measure of how well the body functions at the molecular, cellular, and system levels.” The team compared this information to six years of climate data and found evidence that people exposed to repeated heat waves age more quickly. “Participants living in areas where heat days, as defined as Extreme Caution or higher levels (≥90°F), occur half the year, such as Phoenix, Arizona, experienced up to 14 months of additional biological aging compared to those living in areas with fewer than 10 heat days per year,” said USC’s Eunyoung Choi, a co-author on the study. “Even after controlling for several factors, we found this association. Just because you live in an area with more heat days, you’re aging faster biologically.”
The company behind the UK’s first new nuclear plant to be built in 20 years is considering installing 288 underwater speakers in a nearby river to deter fish from entering the plant’s water intake system. This “fish disco” would generate sounds that are louder than a jumbo jet 24 hours a day for 60 years.
