The more Hurricanes Helene and Milton we get, the harder it is to ignore the need.

As the southeastern U.S. recovers from hurricanes Helene and Milton, the destruction the storms have left behind serves to underline the obvious: The need for technologies that support climate change adaptation and resilience is both real and urgent. And while nearly all the money in climate finance still flows into mitigation tech, which seeks to lower emissions to alleviate tomorrow’s harm, at long last, there are signs that interest and funding for the adaptation space is picking up.
The emergence and success of climate resilience advisory and investment firms such as Tailwind Climate and The Lightsmith Group are two signs of this shift. Founded just last year, Tailwind recently published a taxonomy of activities and financing across the various sectors of adaptation and resilience solutions to help clients understand opportunity areas in the space. Next year, the firm’s co-founder Katie MacDonald told me, Tailwind will likely begin raising its first fund. It’s already invested in one company, UK-based Cryogenx, which makes a portable cooling vest to rapidly reduce the temperature of patients experiencing heatstroke.
As for Lightsmith, the firm held the final close of its $186 million growth equity fund for climate adaptation solutions in 2022, which co-founder and managing director Jay Koh told me is one of the first, if not the first fund with a climate resilience focus. As Koh sees it, the evolution of climate adaptation and resilience technologies can be broken up into three stages, the first being “reactive and incremental.” That’s largely where we’re at right now, he said — think rebuilding a dam higher after it’s been breached in a flood, or making a firebreak broader after a destructive wildfire. Where he’s seeing interesting companies emerge, though, is in the more proactive second stage, which often involves anticipating and preparing for extreme weather events. “Let’s do a lot more data and analytics ahead of time. Let’s deploy more weather satellites. Let’s look at deploying artificial intelligence and other technologies to do better forecasting,” Koh explained to me.
The third and final stage, he said, could be categorized as “systemic or transcendent adaptation,” which involves systems-level changes as opposed to incremental improvements. Source Global, one of Lightsmith’s portfolio companies which makes solar-powered hydropanels that produce affordable drinking water, is an example of this. As Koh told me, “It’s not simply improving the efficiency of desalination filters by 5% or 10%. It’s saying, listen, we’re going to pull water out of the air in a way that we have never done before.”
But while the activity and interest around adaptation tech may be growing, the money just isn’t there yet. “We’re easily $50 [billion] to $60 billion below where we need to be today,” MacDonald told me. “And you know, we’re on the order of around $150 [billion] to $160 billion below where we need to be by 2030.” Everyone else I spoke with echoed the sentiment. “The latest statistics are that less than 5% of total climate finance tracked on planet Earth is attributable to adaptation and climate resilience,” Koh said. “Of that, less than 2% is private investment.”
There’s a few reasons why early-stage investors especially may be hesitant to throw their weight behind adaptation tech despite the clear need in the market. Amy Francetic, co-founder and managing general partner at Buoyant Ventures, which focuses on early-stage digital solutions for climate risk, told me that the main customer for adaptation solutions is often a government entity. “Municipalities and other government contracts, they’re hard to win, they’re slow to win, and they don’t pay that much, either, which is the problem.” Francetic told me. “So it’s not a great customer to have.”
One of Buoyant’s portfolio companies, the now defunct StormSensor, reinforced this lesson for Francetic. The company used sensors to track water flow within storm and sewage systems to prevent flooding and was able to arrange pilot projects with plenty of water agencies — but few of them converted into paying contracts. “The municipalities were willing to spend money on an experiment, but not so many of them had a larger budget.” Francetic told me. The same dynamic, she said, is also at play in the utility industry, where you often hear about new tech succumbing to “death by pilot.”
It’s not all doom and gloom, though, when it comes to working with larger, risk-averse agencies. AiDash, another of Lightsmith’s portfolio companies that uses artificial intelligence to help utilities assess and address wildfire risk, has five utility partnerships, and earlier this year raised $58.5 million in an oversubscribed Series C round. Francetic and MacDonald both told me they’re seeing the conversation around climate adaptation evolve to include more industry stakeholders. In the past, Francetic said, discussing resilience and adaptation was almost seen as a form of climate doomerism. “They said, oh, why are you doing that? It shows that you’re giving up.” But now, MacDonald told me that her experience at this year’s climate week in New York was defined by productive conversations with representatives from the insurance industry, banking sector, and venture capital arena about injecting more capital into the space.
Bill Clerico, the founder and managing partner of the venture firm Convective Capital, is also deeply familiar with the tricky dynamics of climate adaptation funding. Convective, founded in 2022, is solely dedicated to wildfire tech solutions. The firm’s portfolio companies span a range of technologies that address suppression, early identification, prevention, and insurance against damages, and are mainly looking to work with utilities, governments, and insurance companies. When I talked to Clerico back in August, he (understatedly) categorized these establishments as “not necessarily the most fast-moving or innovative.” But the bleak silver lining, he told me, is that extreme weather is forcing them to up their tempo. “There is so much destruction happening so frequently that it’s forcing a lot of these institutions to think about it totally differently and to embrace newer, more novel solutions — and to do it quickly.”
People, it seems, are starting to get real. But investors and startups alike are also just beginning to define exactly what adaptation tech encompasses and what metrics for success look like when they’re less measurable than, say, the tons of carbon sucked out of the atmosphere via direct air capture, or the amount of energy produced by a fusion reactor.
“Nobody wakes up in the morning and buys a loaf of adaptation. You don’t drive around in an adaptation or live in an adaptation,” Koh noted. “What you want is food, transport, shelter, water that is resilient and adapted to the effects of climate change.” What Koh and the team at Lightsmith have found is that many of the companies working on these solutions are hiding in plain sight. “They call themselves business continuity or water efficiency or agricultural precision technologies or supply chain management in the face of weather volatility,” Koh explained.
In this way, the scope of adaptation technology balloons far beyond what is traditionally climate-coded. Lightsmith recently invested in a Brazil-based digital health company called Beep Saude, which enables patients to get rapid, in-home diagnostics, vaccination services, and infusion therapies. It falls under the umbrella of climate adaptation tech, Koh told me, because rising temperatures, increased rainfall, and deforestation in the country have led to a rapid increase in mosquitoes spreading diseases such as dengue fever and the Zika virus.
Naturally, measuring the efficacy of solutions that span such a vast problem space means a lot of customization. “Your metric might be, how many people have asked for water in a drought-prone area?” MacDonald told me. “And with health, it might be, how many children are safe from wildfire smoke during fire season? And for ecosystems, it might be, how many hectares of ecosystem have been saved as a means to reduce storm surge?” Insurance also brings up a host of additional metrics. As Francetic told me, “we measure things like lives and livelihoods covered or addressed. We measure things like losses covered or underwriting dollars spent on this.”
No matter how you categorize it or measure it, the need for these technologies is not going away. “The drivers of adaptation and climate resilience demand are physics and time,” Koh told me. “Whoever develops climate resilience and adaptation technology will have a competitive advantage over any other company, any other society, and the faster that we can scale it up, and the smarter and more equitable we are about deploying it, the better off we will all be.”

Plus three big announcements from the annual hullabaloo.
Now in its fourth year, San Francisco Climate Week is noticeably bigger and buzzier each time I go. When I first attended in 2024, everyone was trying to shoehorn generative artificial intelligence into climate solutions. Last year, founders and funders were struggling to figure out how to deploy capital and stay afloat after Trump took a hammer to Biden-era climate incentives.
This year — which reportedly saw double 2025’s attendance, with roughly 60,000 people choosing from more than 700 events — everyone was banking on the data center buildout, the speed-to-power race, and the broader effort to squeeze more capacity out of the existing grid to save climate tech. Given that the AI race is essentially keeping the U.S. economy afloat during a tumultuous year of tariffs, war, and ongoing energy price shocks, that doesn’t look like such a bad bet, at least for now.
But it wasn’t the only issue at play. Critical minerals were another hot topic, while conversations around adaptation and resilience are finally becoming a bigger part of the picture. I also moderated a surprisingly technical panel on distributed energy resources and virtual power plants, though that inevitably managed to touch on data centers and strategies for managing AI-driven load growth, too.
At Heatmap House, our day of conversations and roundtables with leading climate thinkers, one investor mentioned he had recently backed a lab-grown meat startup – a true contrarian investment if I’ve ever seen one. And my colleague Robinson Meyer hosted a fascinating pair of back-to-back conversations on a controversial geoengineering approach known as solar radiation management, which proposes using aerosolized chemicals to reflect sunlight away from Earth. He first spoke with the CEO of Stardust Solutions, a private company actively building this tech, followed by an advocate for research into solar engineering but certainly not near-term commercial deployment.
It’s impossible to capture the exact essence of a conference with hundreds of individual events — at some level, it’s always going to be what you make of it. But as I bopped around the city shaking hands, I picked up a range of interesting perspectives, along with three pieces of news that I thought were worth unpacking here — one related to funding for critical minerals, and two focused on bringing data centers online as quickly and cleanly as possible.
At a Climate Week event, Atana Elements CEO Thomas Wilson disclosed that the critical minerals exploration startup has quietly closed its seed round, which totals $27.5 million, according to an SEC filing. The round includes participation from Earthshot Ventures, as well as Lowercarbon Capital, and Hitachi Ventures. Last year Atana officially — but stealthily — spun out of Lilac Solutions, a startup developing a cleaner method of extracting lithium from saltwater brines.
But while Lilac is focused on commercializing its novel lithium extraction technology, Atana is tackling the broader upstream mineral discovery process. Its scope includes lithium, but extends to other so-called “flowing” critical minerals dissolved in brines, such as helium, hydrogen, and copper. In the years before the spinout, Atana compiled reams of historical geological datasets — think “Soviet-era oil and gas reports,” Wilson said. It used these to train predictive artificial intelligence models designed to identify previously overlooked mineral deposits.
“You can think of Atana as somewhat analogous to Kobald, but for flowing minerals such as lithium brines rather than hard rock resources,” said Matt Logan of Earthshot Ventures at the event, hosted by the nonprofit climate tech investor Elemental Impact. Kobald similarly uses AI for minerals discovery, and following a $537 million Series C round last year, is reportedly valued at nearly $3 billion.
Atana formed as a team within Lilac back in 2019, benefiting from the more mature startup’s relatively long and well-funded runway — Lilac has raised about $315 million to date. “We have found some of the biggest deposits in the world, and we’ve drilled 19 exploration wells across three continents,” Wilson said. “Around 2% to 3%of the world’s new minerals have been found by this particular team.” That’s a huge number for a startup that’s yet to even formally launch.
To date, Atana has identified a high-grade lithium brine resource in an Argentinean salt flat and secured 1.5 million acres across Germany and Poland, where it’s conducting exploration for lithium brine deposits. While lithium is likely to remain a core market, Wilson said he’s looking forward to broadening Atana’s ambition, asking “now that we’ve been released from the Lilac lithium play, what can we do in copper, helium, hydrogen, and where can we do that in other parts of the world?”
Data center-driven load growth, speed-to-power, and grid flexibility dominated the conversation at SF Climate Week, and the much-hyped data center management platform Emerald AI came prepared with a fitting announcement: It’s partnering with Silicon Valley Power, Santa Clara’s municipally owned utility, not only to demonstrate the benefits of flexible data centers for the grid, but to actually attempt to implement a program that expedites grid interconnection for data centers with flexible loads.
The latter objective differentiates this from Emerald AI’s earlier utility pilots, which were primarily technical demonstrations of its software — proving it can slow, pause, or reroute AI workloads during periods of peak demand without disrupting critical operations, which research shows could unlock nearly 100 gigawatts of grid capacity. This new pilot appears to go a step further by explicitly linking that flexibility to interconnection outcomes. As Emerald AI’s business development lead Daniel Padilla confirmed at a panel, data centers operating flexibly in Silicon Valley Power’s territory “will get material acceleration in time-to-power.”
Santa Clara, which sits about 45 miles south of San Francisco, is a major West Coast data center hub, with roughly 58 facilities packed into 19 square miles, according to Chris Karwick, Silicon Valley Power’s assistant director of utility operations, who spoke later at the same event. Karwick confirmed that the pilot with Emerald includes a “flexible load interconnection program,” and noted that while utilities broadly recognize the need for solutions to rising data center load growth, few are eager to be first movers. “We’re the electric utility for a city. We’re not known for being innovative — we’re usually followers. So this is big for us,” he explained.
Since emerging from stealth last summer, Emerald AI has already raised $67.5 million, and is now working with Nvidia to develop a 96-megawatt flexible data center facility in Virginia called Aurora, which Padilla said is expected to come online in October.
As Heatmap’s end-of-year survey revealed, experts widely consider Meta to be among of the worst hyperscalers when it comes to its climate impact and sustainability efforts. But the company nevertheless maintains a net-zero by 2030 target, even as it continues to bring plenty of new natural gas capacity online to power its AI expansion. Now, however, the company is throwing its weight behind a markedly greener — and less proven — technology, the ultra-long duration energy storage startup Noon Energy.
Meta announced this week that it has reserved 100 gigawatt-hours of storage capacity from Noon, which completed a successful demonstration of its 100-plus-hour carbon-oxygen battery earlier this year. Noon’s system charges by breaking down CO2 and discharges by recombining it using a technology known as a reversible solid-oxide fuel cell, and is certainly one of the earliest-stage data center power technologies that Meta has supported.
“There’s an urgency now that I don’t think existed before,” Carolyn Campbell, head of clean technology innovation at Meta said at a Climate Week panel, referring to the need to deploy emerging energy tech to meet the surge in data-center driven electricity demand. She added that Meta is evaluating how its procurement strategy can help commercialize early-stage climate tech — an area it so far hasn’t backed as extensively as its peers Google and Microsoft.
“When we sign a partnership agreement with a new company, does that help them with their next financing round because their investors see a different level of interest in the technology than they would have otherwise?” Campbell speculated. “Can we provide some upfront development capital to support a pilot that was maybe conceptual — going from concept to reality? So I think that’s one of the things that I’m really excited about with the Noon partnership.”
As I reported earlier this year, Noon CEO Chris Graves expects initial commercial deployments to begin as soon as next year, with early systems installed onsite to allow data centers or other large loads to draw power directly from Noon’s batteries rather than interconnecting to the grid itself. The startup’s collaboration with Meta will kick off with a 2.5-gigawatt-hour project, scheduled for completion by 2028.
Climate tech investors talk investing in moonshots at SF Climate Week.
Three climate investors walked onto a boat.
That’s not the start of a joke — it’s a description of a panel at Heatmap House, a day of conversations and roundtables with leading policymakers, executives, and investors at San Francisco Climate Week (at the Klamath, a venue made out of an old ship).
Heatmap’s Katie Brigham moderated the roundtable conversation with Prelude Ventures Managing Director Gabriel Kra, Azolla Ventures co-founder Matthew Nordan, and Toba Capital Partner Susan Su. Many of their investments are in moonshot climate technologies that other financial players might avoid.
“Things that look contrarian is kind of what we do,” said Kra. “Occasionally, there’s an idea that looks bad that’s actually a good idea.”
Prelude Ventures funds early-stage climate companies that are “weird, or non-consensus, or counter cyclical, or just ahead of the curve,” according to Kra.
Nordan, for instance, said he backs cultivated meat despite some doubts that the category will achieve widespread popularity.
“I’m presently leading an investment in a company called Pythag Technologies,” said Nordan, talking about the generative AI company focused on lab-grown meat. “It’s actually a really interesting time to invest counter-cyclically in a field like that.”
Like Nordan, Su described her firm as one that is open to unconventional choices.
“We are very weird in that we invest across lots of different categories and lots of different stages,” said Su.
One of her personal investments is in Xeno. “This company does electric motorbikes for commercial drivers, as well as swapping and energy networks in emerging markets, starting in East Africa,” she explained.
The panelists told Katie that opting for less popular investments can be rewarding because they may help fund a major breakthrough.
“We placed a couple of bets on fusion before this current melée occurred that sort of had everybody thinking that, you know, fusion was the next hot thing,” said Kra (who claimed that he intended the pun).
Nordan emphasized the gap that venture can fill, left by larger institutional investors who may shy away from high-risk technologies.
“If there are true breakthroughs out there that just may not be investable by mainstream finance at the earliest stages,” Nordan said, “not because people don’t think they’re really good ideas, but they may be crazy early-stage or kind of weird, or non-consensus, or counter-cyclical, or just ahead of the curve, it would be a real shame.”
Noise ordinances won’t necessarily stop a multi-resonant whine from permeating the area.
What did you do for Earth Day this year? I spent mine visiting a notoriously loud artificial intelligence campus in Virginia’s Data Center Alley. The experience brought home to me just how big a problem noise can be for the communities adjacent to these tech campuses – and how much further local officials have to go in learning how to deal with them.
The morning of April 22, I jumped into a Toyota Highlander and drove it out to the Vantage VA2 data center campus in Sterling, Virginia, smack dab in the middle of a large residential community. The sensation when I got out of the car was unignorable – imagine an all-encompassing, monotonous whoosh accompanied by a low rumble you can feel in your body. It sounds like a jet engine that never stops running or a household vacuum amplified to 11 running at all hours. It was rainy the day I visited and planes from nearby Dulles International Airport were soaring overhead, but neither sound could remotely eclipse the thudding, multi-resonant hum.
If you want to hear the sound for yourself, this video accurately sums it up.
After parking nearby I walked to one of the residential enclaves adjacent to VA2. One resident of a home across the street, who declined to give me her name, said she moved there before the project was completed. When asked how she felt about the noise, she told me, “It’s not as bad as it could be on the other side [of the data center], where all the equipment is.” (While the sound does get louder on the other side, I could clearly hear VA2 from her driveway.)
VA2’s noise has been causing problems for months, as documented by numerous social media posts, local news clips, and a feature published in Politico. It’s doubtful many of those living near the data center wanted it there. The project was built quite quickly – so quickly that Google Earth still shows undeveloped woodlands on the site. Per public filings, Vantage first proposed the facility in 2022 under the county’s fast-track commercial incentive program, an expedited permitting process for specific preferred industries. It was under construction as recently as October 2024, according to images captured by Google Street View.
Noise is one of the most common issues associated with data centers. At least a third of all conflicts over data centers are over noise complaints, and noise is the number one reason for opposition in cases where projects were ultimately canceled, according to Heatmap Pro data.
This issue goes back almost a decade. In 2019, residents of the Phoenix ex-urb Chandler, Arizona, became irate after a loud monotonous hmmmm began emanating from a CyrusOne data center. In that case, CyrusOne traced the noise back to chilling fans, and the company reduced the sound with muffling devices.
Chandler wound up adopting a new ordinance in 2023 requiring sound mitigation measures to prevent companies from exceeding certain ambient noise levels in the surrounding areas. That did nothing to improve the mood of the people who live there, however. Now Chandler, once known as a potential data center development hub, is now firmly in the anti- camp. The city council unanimously rejected a proposed $2.5 billion data center campus in December over noise concerns, despite an expensive lobbying push backed by former Arizona Senator Kyrsten Sinema.
As data centers spread across the U.S., noise is becoming an ever-more-common complaint. You can hear the familiar hum at a DataOne data center project in Vineland, New Jersey. DataOne told us they “understand concerns about ambient noise in the area” and are operating within the limits of local noise ordinances.
The hum is also in Dowegiac, Michigan, where people living nearby are calling their new Hyperscale Data facility a “noise trap,” with little explanation to date for the issue. Hyperscale Data did not respond to a request for comment.
And the hum is in Mount Pleasant, Wisconsin, where the sound from a new Microsoft data center campus rises above any din from rain. The hyperscaling giant is doing more to mitigate the issue than I’m used to seeing from data center developers, however.
On April 15, the company published an update on its own internal investigations into noise complaints. “Although the facility noise levels meet the requirements set by local ordinance, we take this feedback seriously and understand the impact this has had on our neighbors,” the update read. “We anticipated that our systems would need adjustments and create some noise as part of the datacenter startup, but we did not expect the tonal quality of the sound to travel as far as it has.”
To address the noise, Microsoft said it was “manually adjusting the cooling fans” to reduce noise, and that “we expect this change to address community concerns about the tonal humming.” On top of that, the company said it will install “additional sound reduction components” to “provide even further reductions in measured sound levels.” A Microsoft spokesperson told me in an email: “We’ve identified the source of the noise concerns and have implemented changes to significantly reduce sound from our facility.”
It isn’t cooling fans causing the noise at Vantage’s VA2 in Virginia, however. The sound, according to media reports, is coming from gas turbines powering the data center.
VA2 is one of the first in Virginia to function entirely off-grid, a design companies are adopting in order to avoid lengthy grid connection processes. Company spokesman Mark Freeman told me the facility is “fully compliant with all local noise ordinances, and this has been verified by third-party sound studies.”
“Additionally, in line with our commitment, we are actively working with third-party engineers to explore additional sound mitigation options,” Freeman continued. Freeman said “Our goal is to further reduce noise levels where possible and continue to foster a positive environment for everyone.”
Here’s the thing, though: I visited the Vantage campus after initially hearing from the company, and it was loud. Very loud.
I did not bring a decibel meter with me, so I cannot know whether they were operating within legal limits that day. What I do know is that noise ordinances struggle to properly capture sounds in multiple frequency ranges, making high and low frequencies challenging to regulate, according to the Environmental and Energy Study Institute, a bipartisan non-profit think tank. Officials representing Loudon County, where VA2 is located, have acknowledged that the local ordinance may need to change in order to address the most distressing frequencies from the data center campus.
“We can change the zoning ordinance and noise ordinance,” Loudon County supervisor Mike Turner told local TV station WUSA9 last week. “Noise can be mitigated. I just don’t believe that the noise problem cannot be solved.”
I wrote Freeman, the Vantage spokesman, to tell him I had visited the VA2 campus and found the noise to be “quite foul.” He replied soon after, telling me that Vantage is going “above and beyond what is required in order to address concerns from nearby residents.” The company is using “targeted enhancements to turbine-related equipment such as dampening equipment, enclosure inlets and enclosure exhausts.” These measures “represent meaningful progress and will help us better evaluate the effectiveness of the broader solutions under consideration.” Freeman also said the company is “actively assessing additional options” focused on “targeted frequency ranges.”
As we continue to track local regulation of data centers, I’m we’ll see many more cases like VA2, in which obtrusive sound prompts forms of regulation we may have never seen before.
Or, people will just hear these noises and say no to more data centers.
