Helene’s winds stretch close to 500 miles across. That’s half the width of the entire Gulf of Mexico.
When Hurricane Helene began to take shape in the Gulf of Mexico, there was one factor that quickly made the storm stand out to meteorologists: its size. Helene is “unusually large,” the National Hurricane Center said; “exceptionally large,” per the Washington Post. Upon landfall, it was one of largest hurricanes in modern history, according to hurricane expert Michael Lowry — bigger than Harvey, bigger than Katrina, surpassed only by 2017’s Hurricane Irma, which was one of the costliest tropical storms on record and resulted in dozens of deaths.
Bigger does not always correlate to stronger. Discussions around the strength of a hurricane typically center on its wind speeds (which is what the categories connote) and the volume of rain it is expected to unleash. But in Helene’s case, there was both size and power — when the storm made landfall in Florida’s Big Bend region late Thursday night, it was classified as a Category 4 storm, with sustained winds of 140 miles per hour.
Florida Governor Ron DeSantis declared a state of emergency in 61 of the state’s 67 counties ahead of the storm, speaking to the breadth of damage he expects to see and the long recovery process to come. Already, images of flooded streets are circulating on social media, multiple deaths have been reported, and millions are without electricity. As Helene continues its course, it’s bringing tropical storm conditions to Alabama, Georgia, the Carolinas, and Tennessee.
In the hours and days to come, we’ll get a better understanding of how well forecasters did predicting the path and strength of this storm, a task that has become increasingly difficult. Because at the same time technology has improved oversight of these storms, with artificial intelligence models that have raised the bar for prediction accuracy and the ability to deploy radar systems as they pass overhead, climate change is altering the ingredients that feed their formation. For example, record-high temperatures in oceans have changed the behavior of storms as they form, Matt Lanza, who monitors Atlantic storm activity for The Eyewall, explained to me, resulting in more storms intensifying rapidly ahead of landfall. This has made storms like 2023’s Hurricane Idalia tougher to predict, despite being closely tracked.
Helene, too, rapidly intensified on its way to reaching land. The area of Florida where it hit, a little over 50 miles from the state capital in Tallahassee, is no stranger to storms— in just the past 13 months, Florida’s Big Bend has had to absorb the impacts of both Idalia and Hurricane Debby, each of which caused billions of dollars in damages. Still, Truchelut said Hurricane Helene could be a “truly unprecedented scenario for North Florida.” Part of the unusual force behind this storm can be attributed to another unprecedented scenario — the warmth of the water in the Gulf of Mexico. CBS News said the water surface temperature below the storm’s formation was up to 89 degrees Fahrenheit, which is as much as 4 degrees above average. This follows the overall Gulf warming trend observed by NOAA, which the agency says “increases the intensity of hurricanes.”
Another factor that allowed Helene to grow so huge so fast was the lack of wind shear, a term meteorologists use to refer to the way wind changes speed or direction or both across different elevations. Strong upper-level winds can inhibit storms from forming or growing. In Helene’s case, however, warm water was accompanied by low wind shear and plenty of moisture— conditions that aligned to provide tremendous energy for the storm’s formation. The only thing really standing in Helene’s way was its own size, Lanza noted, which would have made it more difficult for the storm to get organized and strengthen further.
The most obvious reason size matters is the footprint the storm will have on land. To give you an idea of just how large Helene is, Lowry said in his newsletter Friday that the full breadth of its winds upon landfall stretched over 450 miles across, nearly half the entire width of the Gulf of Mexico. This means the effects of the storm began long before it officially made landfall and will continue long after the eye of the storm has moved on.
Hours before Helene officially reached Florida, rain was already drenching communities in the storm’s projected path. Meanwhile, “Severe and life-threatening impacts from Helene will occur hundreds of miles from the cone confines, especially on the eastern half of the storm,” Florida meteorologist Ryan Truchelut wrote in the Tallahassee Democrat, summing up just how far-reaching Helene’s effects could be. The National Oceanic and Atmospheric Administration issued a self-described “rare news release” on Wednesday to warn of the potential for major flooding as far inland as Appalachia, some 300 miles from the Gulf Coast.
Another serious size-related consideration relates to the potential storm surge, or how far above average tides the water will rise. “When you have a storm this big, you’re just inherently moving a lot of water over a broader area,” Lanza said. As Hurricane Helene’s eye approached Florida, water levels easily surpassed multiple storm surge records. But what stood out to Lanza was not just that the surge was powerful, it was also that the threat of surge was so widespread. “A much smaller storm, you can still have a very large storm surge, but it’s going to be very isolated near to where it comes ashore,” he told me. “With a storm like Helene, because of its size, near and east of where it comes ashore, you’re going to have a massive storm surge — and you’re going to have a pretty big storm surge even down the coast from that.” The NHC warned that much of Florida’s Western coastline would see multiple feet of water.
Messaging the risks of these storms to an extreme weather-weary public is another challenge stemming from climate change. “Record breaking” has now become a familiar phrase for most of us, describing everything from extreme temperatures to rainfall rates. But as tropical storms become more intense, fueled by warming-influenced weather conditions, finding ways to accurately convey threats to the public is increasingly essential.
Ahead of Helene’s landfall, the NHC stressed that the storm surge would be “unsurvivable,” encouraging residents to heed evacuation orders. According to The New York Times, the warnings — paired with memories of those other recent storms — seemed to have worked, leaving Big Bend-area towns “eerily empty.” Even the local Waffle House, a business widely recognized for making its own assessments of hurricane risk, was shuttered on Thursday.
The NHC is experimenting with new graphics in hopes of better conveying risks outside of the classic “cone of uncertainty,” which illustrates the predicted path of a tropical storm’s eye. The center shared an image on social media showing inland risks from storms, not just those along the coast.
So if you noticed the NHC’s risk map for Hurricane Helene colored the entire state in a palette of watches and warnings, the reason why is twofold: Yes, the risks really are that widespread with this storm, but the agency is also trying to get better at telling you about them. And in the case of major hurricane like Helene, the more warning, the better.

It’s not just AI companies taking a beating today.
It’s not just tech stocks that are reeling after the release of Chinese artificial intelligence company DeepSeek’s open-source R1 model, which performs similarly to state-of-the-art models from American companies while using less expensive hardware far more efficiently. Energy and infrastructure companies — whose share prices had soared in the past year on the promise of powering a massive artificial intelligence buildout — have also seen their stock prices fall early Monday.
Shares in GE Vernova, which manufactures turbines for gas-fired power plants, were down 19% in early trading Monday. Since the company’s spinoff from GE last April, the share price had risen almost 200% through last Friday, largely based on optimism about its ability to supply higher electricity demand. Oklo, the advanced nuclear company backed by OpenAI chief executive Sam Altman, is down 25%, after rising almost 300% in the past year. Constellation Energy, the independent power producer that’s re-powering Three Mile Island in partnership with Microsoft, saw its shares fall almost 20% in early trading. It had risen almost 190% in the year prior to Monday.
“DeepSeek’s power implications for AI training punctures some of the capex euphoria which followed major commitments from Stargate and Meta last week,” Jefferies infrastructure analyst Graham Hunt and his colleagues wrote in a note to clients Monday. “With DeepSeek delivering performance comparable to GPT-4 for a fraction of the computing power, there are potential negative implications for the builders, as pressure on AI players to justify ever increasing capex plans could ultimately lead to a lower trajectory for data center revenue and profit growth.”
Investors fear that the proliferation of cheaper, more efficient models may hurt the prospects of technology companies — and their suppliers — that are spending tens if not hundreds of billions of dollars on artificial intelligence investments.
Just last week, both Altman and Mark Zuckerberg, the founder and chief executive of Meta, announced huge new investments in artificial intelligence infrastructure.
Altman’s OpenAI is part of Stargate, the joint venture with Microsoft and SoftBank that got a splashy White House-based announcement and promises to invest $500 billion in artificial intelligence infrastructure. There was already some skepticism of these numbers, with Altman-nemesis Elon Musk charging that certain members would be unable to fulfill their ends of the deal, Microsoft Chief Executive Satya Nadella told CNBC from Davos, “I’m good for my $80 billion.”
Zuckerberg, meanwhile, said late last week that his company was building a data center “so large it would cover a significant part of Manhattan,” which would require 2 gigawatts of electricity to power. (For scale, reactors 3 and 4 of the Vogtle nuclear plant in Georgia are a little over 1 gigawatt each.) He also said that Meta had planned up to $65 billion of capital expenditure this year.
These escalating announcements have been manna to investors in any company that provides the building blocks for large artificial intelligence systems — namely chips and energy, with companies like Nvidia, the chip designer, and power companies and energy infrastructure companies posting some of the best stock market performances last year.
But exactly how cheaper artificial intelligence plays out in terms of real investment remains to be seen. Late Sunday night Redmond, Washington-time, Nadella posted a link on X to the Wikipedia page for Jevons Paradox. The idea dates from 19th century Britain, and posits that increased efficiency in using a resource (in Jevons’ case, coal) could actually accelerate its depletion, as the resource becomes cheaper for the same economic output, encouraging more use of it (in Jevons’ case, iron).
“Jevons paradox strikes again!,” Nadella wrote. “As AI gets more efficient and accessible, we will see its use skyrocket, turning it into a commodity we just can't get enough of.”
Investors in chips and energy companies are hoping that’s the case; at least so far, the market doesn’t appear to agree.
And it just raised a $20 million round of Series B funding.
A century ago, prospectors tromped through remote areas, hoping to spot valuable, mineralized rocks simply poking out of the ground. Eventually, after they found all of the obvious stuff, they progressed to doing airborne geophysical surveys that used tools such as electromagnetic sensing to identify minerals that were just below the surface or highly concentrated. But there’s always been a lot more out there than we had the mechanisms to find. So now, companies are training artificial intelligence models on heaps of historical data to help locate untouched reserves of minerals that are key to clean energy technologies such as electric vehicle batteries and wind turbines.
One of the biggest players in this space is Earth AI, a Sydney-based startup that today announced a $20 million Series B round, bringing the company’s total investment to over $38 million since its founding in 2017. While the company had initially sought to raise $15 million in this round, investor interest was so strong that it exceeded its target by $5 million. Lead investors were Tamarack Global and Cantos Ventures.
Earth AI has a two-stage business model. First, it uses its proprietary software to locate likely deposits and purchases the mineral rights to the land. Then, it sends in its drilling rig and in-house team of geologists to produce mineral samples. The team then shows these samples to mining companies to prove that the area warrants further development and — assuming the miners are interested — sells them the mineral rights. “Because of the scarcity of this, because of the deficit of where we are and where we’re going, these price tags are $500 million to $2.5 billion,” Monte Hackett, Earth AI’s chief financial officer, told me. Huge as that may sound, it’s much less than what a mining company would typically spend doing traditional exploration themselves. This latest funding will allow the startup to purchase additional drill rigs and increase its project pipeline to over 50 sites.
“The problem is obvious,” Hackett told me. “We need $10 trillion of critical metal production by 2050. We’re producing $320 billion, a $9.7 trillion shortfall.” To better locate the trillions of dollars worth of minerals necessary for the energy transition, the startup’s CEO, geoscientist Roman Teslyuk, digitized decades of old Australian geophysical survey data, then overlaid that with remote sensing data such as satellite imagery to train a model to recognize the Earth systems and geological processes that created minerals deposits millennia ago. “Another way I like to think about it is that our algorithm looks for the geological shadow that is cast by a dense mineral body,” Hackett explained in a follow-up email.
Hackett told me that Earth AI focuses specifically on “greenfield” applications — that is, areas where no mining activity or substantial minerals exploration has previously occurred. So far, the company’s discoveries include a significant deposit of palladium, which also contains platinum and nickel, as well as a gold deposit and a molybdenum deposit. “We’re finding things that go against what has been the common sense of the industry so far,” Hackett told me, referencing the company’s palladium discovery. “There was geological consensus that there was no platinum palladium on the East Coast of Australia, and our algorithm learned what it looked like on the West Coast and then identified it on the East Coast.”
While Hackett said Earth AI is open for business anywhere, right now all of its projects are in Australia, where the company has “600 ‘x’s on our treasure map” — that is, likely areas for deposits, Hackett wrote in a follow-up email. Outlining the advantages of doing business there, he explained, “We don’t have to go somewhere where there’s unsavory working conditions or there are issues where we have to put our principles into balance. Here, everything is very regulated and above board.” Plus, mining has long been an important component of the Australian economy. “They’re incredibly efficient at doing this well. So the timeline for development is the shortest compared to other places,” Hackett told me.
This tech could have important domestic implications too, though. As the newly-inaugurated President Trump prioritizes ramping up U.S. production of critical minerals, Earth AI could one day help locate deposits here, as well. And since Australia is a close American ally, the nation could play a key role in helping wean the U.S. off of Chinese imports, providing the U.S. with critical minerals that it can’t now, or perhaps ever, produce in sufficient quantities itself.
On disaster relief, rain in California, and solar power
Current conditions: Storm Herminia could bring fresh flooding to England and Wales, just days after Storm Éowyn • A giant iceberg is on a collision course with the island of South Georgia in the Atlantic Ocean • Phoenix, Arizona, might see rain today for the first time in 156 days.
President Trump signed an executive order establishing a review council to assess the Federal Emergency Management Agency, and said the agency needs to be “drastically” improved. The council will have no more than 20 members, and will include department heads as well as people from outside the government that are appointed by Trump himself. “These non-Federal members shall have diverse perspectives and expertise in disaster relief and assistance, emergency preparedness, natural disasters, Federal-State relationships, and budget management,” the order states. This new council will be tasked with scrutinizing the agency’s disaster relief efforts and making recommendations for improvement. Trump has slammed FEMA and the prior administration for their responses to recent natural disasters, including Hurricane Helene and the wildfires in Los Angeles. Misinformation and conspiracy theories – often floated by Republican politicians and rightwing figureheads – spread quickly in the wake of both emergencies. The executive order insists there are “serious concerns of political bias in FEMA.” While touring hurricane damage in North Carolina a few days ago, Trump suggested “getting rid of” FEMA altogether, although that would require some help from Congress. The Project 2025 playbook from the Heritage Foundation has recommended that FEMA be removed from the Department of Homeland Security, and that programs like the National Flood Insurance Program be privatized.
Rainstorms have prompted flooding alerts in parts of Los Angeles that have been left charred by recent large wildfires. The downpours are helping firefighters get a handle on the blazes that remain, with the Palisades, Eaton, and Huges fires all more than 90% contained. But the city is on edge: Too much rain could trigger landslides and flooding around burn scars. A flood advisory is in effect around the Palisades fire burn scar, and areas surrounding the Eaton fire burn scar are also on high alert. The rain could also bring “toxic runoff” – rainwater laced with the chemicals leftover from burned objects like cars and furniture. Workers have been putting improvised filters over storm drains to try to trap pollutants. The worst of the rain was expected Sunday night and Monday.
In case you missed it: The Department of Interior issued an order suspending the ability of its staff, except a few senior officials, to permit new renewables projects on public land. The document suspended the authority of “Department Bureaus and Offices” over a wide range of regular actions, including issuing “any onshore or offshore renewable energy authorization.” The suspension lasts for 60 days and can only be overridden by “a confirmed or Acting official” in a number of senior roles in the Department, including the secretary. “This step will restrict energy development, which will harm consumers and fail to meet growing electricity demand,” Jason Ryan, a spokesperson for American Clean Power, the clean energy trade group, told Heatmap in an email. “We need an ‘all-of-the-above’ energy strategy, not just a ‘some-of-the-above’ approach.”
President Trump has also requested that the Supreme Court pause all pending litigation on environmental cases, including one focusing on California’s EPA waiver to set and enforce its own vehicle emissions standards. Sources toldReuters the administration has also reassigned four Justice Department attorneys that focus on environmental issues, so that the government “speaks with one voice.”
U.S. power generation growth will be led mostly by new solar power additions over the next two years, according to the Energy Information Agency. It expects 26 gigawatts of solar to be added in 2025, down from 37 GW in 2024. Wind power additions are expected to increase by about 8 GW this year, but honestly, who knows. Meanwhile, 6% of coal generating capacity will be removed this year as coal plants are retired. U.S. energy consumption is expected to continue growing at its current rate of about 2% per year through 2026, which would mark the first three years of consecutive growth since the early 2000s.

Here’s a little bit of good news to start the week: Trade group data suggests that air-source heat pump sales outpaced those of gas furnaces by 37% in the U.S. last year – or at least through November. If confirmed, that would be the widest margin recorded, much bigger than last year’s 21%. “The data comes with a notable caveat,” Canary Mediacautioned. “Heat pumps outsold gas furnaces, but that doesn’t necessarily mean more households are choosing heat pumps over gas heating; homes often need multiple heat pump units to replace a single fossil fuel-fired appliance.”
“We spend a lot of time talking about short-term financials, but we’re building a business for the next few decades. So, eh, who cares? It’s going to be a little more challenging the next couple of years.”
