Dr. Cliff Kapono sometimes still surfs the way his Indigenous Hawaiian ancestors did 1,000 years ago, on a traditional wooden board and all. But the professional surfer and molecular biologist fears his descendants might not have the same privilege. The reason is the looming scarcity of surfable waves.
While climate change could be a boon for big-wave surfers, as some have highlighted, the beloved recreational side of the sport is endangered by the shifting climate. Dramatic changes are already locked in, with rising waters swallowing surf breaks and wary communities erecting sea walls that alter the shape of the coastline. But this tension — between the masses losing access to cherished resources and the few who benefit even as they lament — is not exclusive to surfers; it’s one that bedevils almost anything related to climate adaptation.
There are several ways climate change could jeopardize surfing, but the most dramatic is also the most counterintuitive: sea level rise could drown waves.
Put simply, surfing is made possible by the interplay of water and wind. Waves form as energy from gusts passes through water and underwater obstacles (shallower ocean floor, coral reefs, even a man-made jetty) trip them up, allowing the top of a wave to crest as the water below the surface slows down. Whether it’s surfable, however, depends on everything from the break’s geography to how high the tide is on any given day.
Models of future wave conditions indicate sea level rise could change the shape of waves that generations of surfers have relied on. A2017 analysis of 105 California surf spots found that 34% are at risk of “drowning” by 2100, meaning the wave will break too close to shore or not at all. Just 5% of the state’s surf spots are expected to improve, the study found.
Erosion, which will alter the shape of coastlines, is partly to blame. But surfing’s precarity also results from the larger volume of water inherent to sea level rise. Many breaks perform best at low or medium tide; but in most places, sea level rise will push high tide higher while rendering low tide unrecognizable.
Accordingly, head of the Surfrider Foundation’s coast and climate initiative Stefanie Sekich said, “millions of people … will have their surf breaks drowned before their eyes.” Sekich herself has already seen a treasured and unnamed pocket break near San Diego swallowed up by erosion.
Climate change could also result in changes in the water quality that make surfing untenable, such as algal blooms that release toxins that kill fish and irritate swimmers’ skin.
Warmer waters also can stress the coral reefs that often help shape the most reliable surf breaks. This causes them to expel the algae living within them (“bleaching”) and leaves them at risk of dying off entirely.
“A balance and a natural flow that has existed over millennia is being disrupted as a result of human interaction,” Kapono said of this suite of effects. “And change is difficult for people. It requires either time or money, patience or adaptation.”
Determining how to adapt to this change, however, involves hard choices about what we value and why. Surf communities vulnerable to coastal erosion are being forced to weigh the risk that homes could slip into the sea against the risk that new infrastructure could upend a chief reason people seek to live there in the first place: surfing, and the lifestyle and natural splendor that goes with it.
Nik Strong-Cvetich, who leads the non-profit Save the Waves Coalition, argues that surf breaks themselves have unappreciated economic power. In the last 70 years, surfing’s spread has transformed it from a spiritual and social practice for small island communities to a global sport. But towns like his own Santa Cruz, California, do not account for ridable waves when it comes to erecting sea walls, breakwaters, and other manmade structures along the shore, even though the waves are the main attraction for many tourists and transplants.
This so-called “armoring” of the coast via cement structures designed to simultaneously block the waves and prevent the shore’s slip into the sea can negatively impact intertidal ecosystems and even hasten beach erosion. The California Coastal Commission, charged with protecting coastal resources and regulating development, has accordingly become choosier about where this armoring is allowed; in recent cases, it has required owners of new coastal properties to waive their rights to future sea walls to protect their vulnerable developments.
Still, a cement-forward approach to adaptation, Strong-Cvetich said, is among climate change’s biggest threats to surfing, and to the ecosystems and economies that go hand-in-hand with the sport. His organization, Save the Waves, argues for nature-based solutions to sea level rise, such as dune restoration, and for legally protecting surf breaks.
This latter point is controversial. For non-surfers it can sound an awful lot like prioritizing recreation over people’s homes. But if done well, Strong-Cvetich maintains, it is possible to both protect surfing and walk back people’s exposure to environmental hazards.
Both Save the Waves and Surfrider are joining those calling for the government to fund relocating some vulnerable coastal neighborhoods. This too is quite controversial. Several California towns have already considered and shot down “managed retreat” proposals, which many affected homeowners view as jeopardizing the value of their beachfront properties. Meanwhile, a California Legislative Analyst report found that sea level rise is projected to submerge $10 billion worth of property by 2050.
In the midst of any likely climate tragedy, there will be those that come out ahead. When it comes to surfers and climate change, one prominent story goes, the winners are the big-wave surfers.
For certain elite surfers, there may be some truth to this. The swells that launch the waves sky-high at breaks like Nazaré result largely from storm activity thousands of miles offshore; one of climate change’s knock-on effects is stronger hurricanes and surface winds, which cause those swells to carry even more energy within them. In fact, this has already begun to happen, with global wave power increasing 0.4% per year since 1948, according to a 2019 study.
In combination with sea level rise, this has the potential to fuel the monster waves that surfers like Garrett McNamara and Kai Lenny watch for.
Kurt Korte, vice president of forecasting for the surf report service Surfline, said the question of where new 100-footers could be found lingers in the back of his mind as his team monitors changing ocean conditions.
“When you see a storm system that does something a little bit atypical, or you see a shift in the general pattern from one winter to the next, you get … thinking about what that may mean,” Korte said. He expects that climate change makes uncovering the next Nazaré especially likely at higher altitudes: think Alaska, Western Canada, or Greenland.
This would be a boon for the extreme surfers that increasingly get the spotlight in documentaries like the glossy HBO documentary series 100 Foot Wave — and for the fans that devour footage of their work. But the rise of monster waves while gentler, warmer breaks are swallowed would represent a gradual sea change for surfing more broadly: from leisure activity to extreme sport, most accessible to those who can afford the training, equipment, and travel required, and increasingly unrecognizable to Kapono’s ancestors
But Li Erikson, a research geographer at the U.S. Geological Survey, notesher own team’s models paint a more nebulous picture of the big-wave future. While there are some places where waves are projected to grow taller (including at the higher latitudes), there are others where they are expected to shrink.
As is so often the case in conversations of the climate crisis’ winners and losers, treating bigger and better waves as a foregone conclusion betrays both a desire to simplify the phenomenon’s effects, and to focus on the not-that-bad-actually-perhaps-even-good elements of the story. While this might be an effective coping mechanism, it’s also one that threatens to distract us from adapting before it’s too late.
The reality of the surf community’s experience of climate change is one that mirrors our collective experience: A few will gain, while most will lose. For instance, the internet brims with articles on the few regions that will fare best when so much of the world weathers floods and drought and fires. (The area around the Great Lakes seems particularly promising.) And while climate change has already caused the number of people suffering from hunger in some of the world’s most vulnerable countries to more than double since 2017, a warming Siberia will see its lucky farmers able to produce new crops.
Preserving what we value in the face of climate change is complicated and often overwhelmed by the sheer volume of what we stand to lose. But sticking our heads in the sand and relying on a sea wall to save us only promises to compound our grief. Adaptation is the task of stemming the losses, especially while resources still abound.
“There’s a finite number of people that are really impacted by the big wave stuff,” Korte said. But when it comes to the future of the smaller coastal breaks that have lured an increasing number of surfers into the water, he added, millions stand to lose.

On the Greenhouse Gas Reduction Fund, Canada’s new prime minister, and CERAWeek
Current conditions: Firefighters successfully controlled brush fires in Long Island that prompted New York Gov. Kathy Hochul to declare a state of emergency • Brisbane, Australia, recorded its wettest day in more than 50 years • Forecasters are keeping an eye on a storm system developing across the central U.S. that could pack a serious punch this week.
The nonprofit Climate United filed a lawsuit over the weekend against the Environmental Protection Agency and Citibank for withholding $7 billion in climate funds awarded as part of the Biden administration’s Inflation Reduction Act. The move escalates a dispute over some $20 billion in grants from the IRA’s Greenhouse Gas Reduction Fund, which was designed to help mobilize private capital toward clean energy and climate solutions. President Trump’s EPA Administrator Lee Zeldin has been on a mission to claw back the funds, claiming their distribution was rushed and mismanaged. In its lawsuit, Climate United says it has been unable to access the $7 billion it was awarded, and that the EPA and Citibank have given no explanation for this. It wants a judge to order that the money be released. “We’re not trying to make a political statement here,” Beth Bafford, chief executive of Climate United, toldThe New York Times. “This is about math for homeowners, for truck drivers, for public schools — we know that accessing clean energy saves them money that they can use on far more important things.” The Trump administration has reportedly demanded that the eight organizations tapped to receive the money turn over records to the FBI and appear in federal court later this month.
Canada’s Liberal Party has elected Mark Carney, a net-zero finance advocate, to succeed Justin Trudeau as prime minister. Carney is not a career politician. Instead, he comes from the financial world, having overseen both the Bank of Canada and the Bank of England, and is an evangelist for green investment and a net-zero financial sector. He was the UN Special Envoy for Climate Action and Finance in 2019, and “has made clean energy, climate policies and economic prosperity for Canada some of the central facets of his campaign,” CNN reported. If he wins the upcoming general election, Carney will be tasked with navigating President Trump’s tariffs and making key decisions about the future of Canada’s vast natural resources, including fossil fuels and rare minerals.
The U.S. has withdrawn from yet another global climate initiative, this one aimed at helping developing nations recover from natural disasters. The United Nations loss and damage fund was one of the biggest wins to come out of COP28 in 2023, with nearly 200 countries signing on in support. It’s expected to start funding projects this year. About $740 million has been pledged so far, and the U.S. has said it will give about $17.5 million, though it’s unclear if that money will actually be handed over now. “This decision, made by the nation with the largest historical responsibility for climate change, jeopardises vital support for vulnerable countries facing irreversible climate impacts,” said Ali Mohamed, the chair of the African Group of Negotiators.
The energy industry descends on Houston, Texas, this week, for the annual CERAWeek conference. This year’s event, titled “Moving Ahead: Energy Strategies for a Complex World,” will focus on the changing global energy landscape. Key themes include shifting regulations, the turbulent oil and gas market, electrification and power demand, the rise of AI, managing emissions, and the policy outlook for renewables. According toReuters energy columnist Ron Bousso, fossil fuel executives are going into the conference with a case of “Trump buyer’s remorse” as new tariffs and geopolitical policies from the Trump administration have “created turmoil in financial markets and clouded the outlook for the global economy and energy prices.”
Argentina will observe three days of national mourning after 16 people were killed in flash flooding over the weekend triggered by unprecedented rainfall. Nearly a year’s worth of rain – about 16 inches – fell in just eight hours in the port city of Bahia Blanca in the Buenos Aires province. Many people are still missing. Environment official Andrea Dufourg said the event was a clear example of climate change. “Unfortunately this will continue to take place,” Dufourg said. “We have no other option than to prepare cities, educate citizens, and establish effective early warning systems.”
Twenty-one House Republicans have signed a letter urging the GOP to uphold the Inflation Reduction Act’s clean energy tax credits in their budget bill, warning that gutting the credits would “risk sparking an energy crisis in our country, resulting in drastically higher power bills for American families.” That’s three more than signed a similar letter during the last Congress.
While they’re getting more accurate all the time, they still rely on data from traditional models — and possibly always will.
The National Oceanic and Atmospheric Administration has had a bruising few weeks. Deep staffing cuts at the hands of Elon Musk’s efficiency crusaders have led to concerns regarding the potential closure of facilities critical to data-gathering and weather-forecasting operations. Meteorologists have warned that this could put lives at risk, while industries that rely on trustworthy, publicly available weather data — from insurance to fishing, shipping, and agriculture — are bracing for impact. While reliable numbers are difficult to come by, the agency appears to have lost on the order of 7% to 10% of its workforce, or more than 1,000 employees. NOAA’s former deputy director, Andrew Rosenberg, wrote that Musk plans to lay off 50% of the agency, while slashing its budget by 30%.
Will that actually happen? Who the heck knows. But what we can look at are the small cracks that are already emerging, and who could step in to fill that void.
One thing that’s certain is that the National Weather Service, a division of NOAA, announced last week that it is suspending operations at a weather balloon launch site in Alaska, due to staffing shortages. The data gathered at this remote outpost helped inform the agency’s weather forecasts, which are relied upon by hundreds of millions of people, as well as many of the world’s largest companies and public agencies.
Perhaps to Musk’s department, this looks like a prime opportunity for the private sector to step up and demonstrate some nimble data gathering prowess — and indeed a startup that I’ve covered before, WindBorne, has already offered its services. The company, which makes advanced weather balloons, has offered to provide NOAA with data from its own Alaska launches for six months, at no cost. WindBorne is also one of a number of private companies creating AI-based weather models that have outperformed NOAA’s traditional, physics-based models on key metrics such as temperature, wind speed and direction, precipitation, humidity, and pressure.
All this raises the question, though, of what kind of role the private sector could and should play in the weather forecasting space overall. If the architects of Project 2025 have their way, NOAA would be “broken up and downsized,” and its National Weather Service division would “fully commercialize its forecasting operations.” If the Trump administration achieves these goals, “the Weather Service would cease to function in a way that it could meet its mandate to protect American life and property,” Daniel Swain, a climate scientist at University of California Agriculture and Natural Resources, told me.
But given that heavyweights like Google, Huawei, and Nvidia are already in the AI-based weather prediction game, along with startups such as WindBorne and Brightband, which is making weather predictions tailored to the needs of specific industries such as insurance, agriculture, or transportation, it wasn’t clear to me whether, if NOAA were to crumble, the accuracy of weather forecasts necessarily would, too. I thought that perhaps Musk, the White House’s most notorious AI enthusiast, might be thinking the same thing. So I asked around.
“There’s actually a very good argument that I think would be very uncontroversial to expand the role of the private sector, even to offload certain parts of the workflow to the private sector,” Swain told me, with regards to NOAA and its adoption — or lack thereof — of AI-based weather forecasting. But what nobody wanted was to get rid of free, publicly available government forecasts completely.
“I don’t want to have to figure out what company to trust. I just want to be able to go and open the National Weather Service and know what’s going on,” John Dean, the CEO and co-founder of WindBorne, told me.
Julian Green, the CEO and co-founder of Brightband, agreed. “The government doesn’t just forecast the weather, but it gives people alerts. And there’s regulation around whether [it tells you that] you should evacuate, or shut your factory down, or so on.” It’s not hard to imagine the ethical quandaries that could arise from a private company with a profit motive deciding who can access potentially life-saving forecasts, and for how much.
WindBorne’s and Brightband’s AI models, as well as those from tech giants such as Google, are significantly less computationally intensive to operate than those from NOAA or the other leading weather forecasting agency, the European Center for Medium-Range Weather Forecasts. These traditional models rely on supercomputers crunching complicated atmospheric equations based on the laws of physics to make their predictions.
But this doesn’t mean the physics-based models are getting replaced by AI now, or potentially ever. Government data and traditional forecasts still make up the backbone of advanced AIs, which are trained on decades of data largely gathered by NOAA satellites, weather balloons, and radar systems, and then interpreted through the lens of standard physics-based models. After training is complete, the AI models can predict what weather patterns will develop, much like ChatGPT predicts the next word in a sequence, but only after being fed a snapshot of initial weather conditions — also pulled from traditional physics-based models.
Essentially, these AI forecasts are built on the backs of the giants, and while their outcomes are hugely promising, they could not exist without that solid foundation. While one day, it might be possible to operate AI forecasting models without relying on traditional models, Dean and Green told me that physics-based models might always be critical for training the AI. So while their companies’ respective models have yielded impressive results, both Dean and Green nixed the idea that their companies could wholly replace the predictions made by the National Weather Service.
All of this is in flux of course, but as Green put it to me in an email, “a good mechanic doesn't throw away good older tools just because you get new tools.” Plus, as Dean explained, there are still conditions under which physics-based models tend to outperform AI, such as “really small-scale and high-res phenomena — let’s say convective events, let’s say severe thunderstorms in the Plains, or tornado formation.”
Even Project 2025’s authors point out that private industry forecasters rely on publicly available NOAA data, though it doesn’t make any reference to AI models or physics models. The document simply says that the agency “should focus on its data-gathering services” and the “efficient delivery of accurate, timely, and unbiased data to the public and to the private sector.”
There are also questions around whether AI models, trained on data from the past, will be able to predict the types of unusual and extreme weather events that are becoming more and more common in a warming world, Swain told me. “Does it fully capture those?” he asked. “There’s a lot of evidence that the answer is no.”
Lastly, NOAA’s weather model, the Global Forecast System, is simply measuring much more than the AI models do today. “It predicts so many different phenomena, like different types of snow, hail, mixing ratios, turbulence,” Dean said. “We’re building up over time to add more and more variables. But for both WindBorne and other models, it’s not the same currently as what GFS does.”
So while the Heritage Foundation might want to delegate all forecasting responsibilities to private companies, the vision I heard from the startups I talked to looked more like a mutually beneficial arrangement than the full commercialization of weather prediction, or even a clean division of labor. “It’s not privatized weather, it’s a public-private partnership,” Dean said of his ideal future, “where you get freely available forecasts from a public institution like NOAA, but they work with our industry to iterate faster and to drive more innovation.”
What everyone seems to want is simply for the government to forecast better, and today that means moving quickly to build AI-based models. NOAA has taken some steps forward, prototyping some models, bolstering its computing capabilities, and even recently partnering with Brightband to optimize its observational data to train AI models. But it remains behind other agencies in this regard. “The Chinese government and the European Center for Medium Range Weather Forecasts have done a far better job at adopting AI-based weather forecasts than NOAA has,” Dean told me. “So something does need to change at NOAA to get them to move faster.”
Indiscriminately laying off hundreds of the agency’s employees may not be the best place to start. But if there’s anything we know Musk loves, it’s AI and private sector ingenuity. So maybe, just maybe, this administration will be able to forge the kind of partnerships that can supercharge federal forecasting, while keeping NOAA’s weather predictions free and open for all. Or maybe we’ll all just be paying the big bucks to figure out when a hurricane is going to hit.
On energy transition funds, disappearing butterflies, and Tesla’s stock slump
Current conditions: Australians have been told to prepare for the worst ahead of Cyclone Alfred, and 100,000 people are already without power • Argentina’s Buenos Aires province has been hit by deadly flooding • Critical fire conditions will persist across much of west Texas through Saturday.
Many foreign aid programs have reportedly received a questionnaire from the Trump administration that they must complete as part of a review, presumably to help the government decide whether or not the groups should receive any more federal funds. One of the questions on the list, according toThe New York Times, is: “Can you confirm this is not a climate or ‘environmental justice’ project or include such elements?” Another asks if the project will “directly impact efforts to strengthen U.S. supply chains or secure rare earth minerals?” President Trump issued an executive order freezing foreign aid on his first day back in office. The Supreme Court subsequently ruled that aid must be released. The Times notes that “many of the projects under scrutiny have already fired their staff and closed their doors, because they have received no federal funds since the review process ostensibly began. … Within some organizations, there are no staff members left to complete the survey.”
The United States has withdrawn from a global financing program aimed at helping poorer nations ditch fossil fuels and shift to clean energy. A spokesperson from the Treasury Department said the Just Energy Transition Partnership does not align with President Trump’s vision of American economic and environmental values. The program was launched in 2021 and has 10 donor nations, including many European countries. Its first beneficiaries were Indonesia, Senegal, South Africa, and Vietnam. The U.S. had committed more than $3 billion to Indonesia and Vietnam and nearly $2 billion to South Africa under the initiative. “The U.S. withdrawal is regrettable,” said Rachel Kyte, the U.K.’s climate envoy. “The rest of the world moves on.” In January, the Trump administration canceled $4 billion in pledges to the Green Climate Fund. “We have to plan for a world where the U.S. is not transfusing funds into the green transition,” Kyte added.
Butterfly populations in the U.S. are rapidly declining due to a combination of climate change, habitat loss, and pesticide exposure, according to a “catastrophic and saddening” new study published in the journal Science. “Butterflies are vanishing from the face of the earth,” one of the study’s co-authors told The Washington Post. The research analyzed data from 77,000 butterfly surveys and found that butterfly numbers have fallen by 22% in just 20 years across the entire country. Of the 342 butterfly species that could be analyzed for trends, 107 plummeted by more than 50% and 22 by more than 90%. Just nine species saw their numbers rise. The researchers say these numbers are likely an underestimate.
The findings underscore the crisis facing all the small, underappreciated insects that pollinate flowers and crops, control pests, maintain soil health, and play a vital role in the food chain. According to the World Wildlife Fund, up to 40% of the world’s insect species may disappear by the end of the century. The study’s lead author, ecologist Collin Edwards, said there is some hope. “Butterflies have fast life cycles,” he said. “At least one generation per year, often two or three. And each of those generations lays a ton of eggs. This means that if we make the world a more hospitable place for butterflies, butterfly species have the capacity to respond very quickly and take advantage of all our efforts.”
The Government Accountability Office yesterday said that Congress can’t review (or repeal) the Environmental Protection Agency’s waiver that lets California set its own vehicle emissions standards. The decision derails plans being spearheaded by Republicans and EPA Administrator Lee Zeldin to use the congressional review process to overturn the waiver. California’s aggressive emissions standards, which have been adopted by many other states, would effectively end the sale of fully gas-powered cars by 2035. Republicans are mulling their next move.
Tesla’s stock price has been taking a beating as resentment grows around CEO Elon Musk’s political meddling. The company’s valuation soared from around $800 billion to $1.5 trillion in December, when it became clear Musk would become the president-elect’s right hand man. Since that moment, the company’s value has fallen by more than $600 million, effectively erasing the bump in Tesla’s market cap. Shares fell by 5.6% yesterday alone, and sales are cratering abroad and in key U.S. markets like California.
As Andrew Moseman explains for Heatmap, a big drop in sales could be a double-whammy for Tesla revenue. “Recall that the company’s most reliable revenue stream is not really its sales of electric cars, but rather the carbon credits generated by those EVs under California’s auto emissions regulatory scheme, which it can sell to other automakers who’ve yet to meet their emissions targets,” Moseman says. “Tesla’s tumbling sales in the wake of Musk’s antics could reduce the amount of credits it could sell to others, since the credits are tied to sales of low-emissions vehicles.” There was more bad news for Musk today: A SpaceX Starship rocket exploded during a test flight, sending flaming debris flying across a large area and disrupting air traffic in Florida.
A new report shows that a year after London expanded its low-emissions zone, air quality in the city has improved, with nitrogen dioxide levels across 2024 down significantly:
