Will America’s luck hold in 2024? The oddsmakers — that is, scientists — have a bad feeling.
Are you feeling lucky?
Americans are. Close to two-thirds say they’ve gambled in the past year; the sports pages are filled with headlines detailing the fallout of various investigations and scandals. But while there isn’t exactly a bookmaker for something like the Atlantic hurricane season, meteorologists around the country are feeling pretty good about their bets this time around.
“We could be extremely wrong and only have two hurricanes,” Philip Klotzbach, one of the authors of the Colorado State University’s 2024 forecast, which came out earlier this month and predicted a whopping 23 named storms, told me. “But I think the odds of that this year are very low, just because the Atlantic is so warm.”
Traditionally, early spring is when Americans begin to hear from agencies and universities about the upcoming Atlantic storm season. That won’t peak for another four or five months, and from the safety of April, it can be tough to muster concern about what late summer might yet inflict upon the nation’s coasts.
Still, the trickle of headlines this year has been nothing short of alarming. In addition to CSU’s prediction, North Carolina State University issued a forecast of between 15 and 20 named storms in 2024, meaning we could potentially tick well above the 1991-2020 average of 14 per year. On Wednesday, the Weather Channel upped the ante with a new estimate of 24 named storms. AccuWeather Lead Hurricane Forecaster Alex DaSilva told me his team estimates there is a 15% chance of 30 or more named storms this year — enough to break the record set in 2020 and exhaust the World Meteorological Organization pre-prepared list of 21 storm names, forcing it to dip into its new and never-before-used “supplemental” list.
Meanwhile, the National Oceanic and Atmospheric Administration is busy putting together its own forecast, a massive, multi-agency collaboration between the National Climate Prediction Center, the National Weather Service, the National Hurricane Center, and NOAA’s Atlantic Oceanographic & Meteorological Laboratory. While the government’s final prediction is still a few weeks away from being made public in May, Matthew Rosencrans, the lead hurricane season forecaster at NOAA’s Climate Prediction Center, told me the agency’s ocean team has been providing monthly briefings on the Atlantic’s record warmth to the forecasters. Of particular concern to the teams is the fact that even if the summer sea surface warms at the lowest rateof any year since 1980, 2024 will still be in the top four of all sea surface temperature years since then.
Michael Lowry, the hurricane and storm surge specialist at Miami’s WPLG Local 10 News, told me this is what has him the most alarmed. “I struggle to find a good language to say how extreme and unprecedented it is, but it’s extreme and unprecedented and almost scary, the amount of warmth that we’re looking at in the Atlantic,” he said.
Warm water, of course, is hurricane Red Bull — it can increase a storm’s destructive potential, taking forecasters by surprise. In addition to the waning El Niño and the likely start of a La Niña — which will make the wind conditions more favorable to Atlantic storm formation — all the agencies I spoke with cited the sea-surface temperatures as a concerning complication in their predictive models. Klotzbach, the CSU researcher, told me the record-warm water gives him more confidence in his models than he would otherwise have this early in April because of the strong correlation between warm waters and storm formation; DaSilva, at AccuWeather, told me it is these same temperatures that have made him concerned about the potential for rapidly intensifying storms like Hurricane Ian in 2022.
Kerry Emanuel, professor emeritus in atmospheric science at MIT, was not as impressed by the predictions, however. Putting a numerical estimate on how many hurricanes will form in the North Atlantic in a given season is “not really very interesting or practical,” he told me. “If you’re a gambler, and you’re placing a bet, OK — but if you’re a coastal resident, what you really care about is relatively intense landfalling storms.”
The more storms there are in the Atlantic in a given season, the more likely intense storms will make landfall — “but not a lot” more likely, Emanuel stressed. Because of that, when it comes to making hurricane season predictions, “I wish NOAA would knock it off because it’s intentionally misleading,” he said.
Emanuel wasn’t alone in his dismissal of the seasonal forecasts. “I’ve got to be straight with you: I think they have limited utility,” John Cangialosi, a senior hurricane specialist at the National Hurricane Center, who focuses more on tracking storms as they form, told me. “It’s sort of like in Powerball, when someone sees $30 million and is like, ‘I’m going to play if it’s $5 million or not,’” he added. “It’s so damn silly. You need to worry about this no matter what.”
That’s because describing hurricane seasons as “quiet” or “active” is really a matter of perspective, even if it makes for good headlines. For example, most people consider 2023 to have been a quiet year since almost no major storms made landfall on U.S. coasts. “But it was a very busy season; just fortunately, most of the storms stayed out at sea,” Klotzbach, of CSU, told me.
In a sense, America merely got a lucky break. While Hurricane Idalia, the strongest storm to hit Florida’s Big Bend region in 125 years, made landfall in 2023, its greatest impact was in a sparsely populated area, leading to limited damage and loss of life. On the other hand, 1992 was technically a “quiet” year for hurricane formation, but all it took was one storm — in that case, Hurricane Andrew, which killed over 60 people and was one of the costliest storms in U.S. history — to cement it in our collective memory.
Further complicating the picture that hurricane forecasts paint is, of course, climate change. The combination of record-warm Atlantic waters and a forecast for an active year makes it tempting to tie the two together. “The human mind is so good at pattern recognition that it wants to attribute a cause to every effect,” Emanuel, the MIT professor, said.
But there’s a whole cocktail of factors driving the Atlantic’s bonkers-warm temperature, including the aforementioned El Niño, which is just part of a naturally occurring global weather pattern known as ENSO; the decreasing presence of sulfur dioxide aerosols, which have a cooling effect; the Tonga volcano eruption, which might have had a temporary warming effect; and yes, greenhouse gas emissions. The lack of clarity around this larger picture has led some researchers to sound an alarm about the urgency of sharpening our understanding; climate change, however, can only confidently be credited with a small portion of the current anomalous spike in sea surface temperatures, which in turn only explains only about 35% to 40% of the changes in tropical cyclone activity.
“It’s not fair to say climate change has caused record warmth, which has caused record hurricanes,” Cangialosi, at the Climate Prediction Center, said. “Because, guess what? Next year we could be in a cool phase — and then where did climate change go?”
That’s far from saying climate change isn’t a factor at all; we just need to be careful with our scales. Besides, there are things we know are directly connected to climate change — like rising sea levels and increased rainfall — that will make hurricane landfalls deadlier in the coming decades.
Hurricane forecasts aren’t totally useless, either. For one thing, they have enormous scientific value, helping researchers better understand the amalgamation of conditions that go into the formation of a major tropical storm. Lowry, the Florida-based meteorologist, also joked they can help confirm that “my job may be a lot busier in the next few months.”
There is a public value, too: Headlines inarguably help keep the approaching season top-of-mind. This is especially important for the masses of new residents who have recently moved to the Gulf Coast and Southeastern shores — undeterred by subsidized insurance rates that don’t properly warn of the region’s risk — and might lack knowledge of how to prepare for the season.
After all, Mother Nature ultimately has the house advantage. And while America was spared a catastrophic storm in 2023, luck has a funny way of running out.

Instead of rocket fuel, they’re burning biomass.
Arbor Energy might have the flashiest origin story in cleantech.
After the company’s CEO, Brad Hartwig, left SpaceX in 2018, he attempted to craft the ideal resume for a future astronaut, his dream career. He joined the California Air National Guard, worked as a test pilot at the now-defunct electric aviation startup Kitty Hawk, and participated in volunteer search and rescue missions in the Bay Area, which gave him a front row seat to the devastating effects of wildfires in Northern California.
That experience changed everything. “I decided I actually really like planet Earth,” Hartwig told me, “and I wanted to focus my career instead on preserving it, rather than trying to leave it.” So he rallied a bunch of his former rocket engineer colleagues to repurpose technology they pioneered at SpaceX to build a biomass-fueled, carbon negative power source that’s supposedly about ten times smaller, twice as efficient, and eventually, one-third the cost of the industry standard for this type of plant.
Take that, all you founders humble-bragging about starting in a dingy garage.
“It’s not new science, per se,” Hartwig told me. The goal of this type of tech, called bioenergy with carbon capture and storage, is to combine biomass-based energy generation with carbon dioxide removal to achieve net negative emissions. Sounds like a dream, but actually producing power or heat from this process has so far proven too expensive to really make sense. There are only a few so-called BECCS facilities operating in the U.S. today, and they’re all just ethanol fuel refineries with carbon capture and storage technology tacked on.
But the advances in 3D printing and computer modeling that allowed the SpaceX team to build an increasingly simple and cheap rocket engine have allowed Arbor to move quickly into this new market, Hartwig explained. “A lot of the technology that we had really pioneered over the last decade — in reactor design, combustion devices, turbo machinery, all for rocket propulsion — all that technology has really quite immediate application in this space of biomass conversion and power generation.”
Arbor’s method is poised to be a whole lot sleeker and cheaper than the BECCS plants of today, enabling both more carbon sequestration and actual electricity production, all by utilizing what Hartwig fondly refers to as a “vegetarian rocket engine.” Because there’s no air in space, astronauts have to bring pure oxygen onboard, which the rocket engines use to burn fuel and propel themselves into the stratosphere and beyond. Arbor simply subs out the rocket fuel for biomass. When that biomass is combusted with pure oxygen, the resulting exhaust consists of just CO2 and water. As the exhaust cools, the water condenses out, and what’s left is a stream of pure carbon dioxide that’s ready to be injected deep underground for permanent storage. All of the energy required to operate Arbor’s system is generated by the biomass combustion itself.
“Arbor is the first to bring forward a technology that can provide clean baseload energy in a very compact form,” Clea Kolster, a partner and Head of Science at Lowercarbon Capital told me. Lowercarbon is an investor in Arbor, alongside other climate tech-focused venture capital firms including Gigascale Capital and Voyager Ventures, but the company has not yet disclosed how much it’s raised.
Last month, Arbor signed a deal with Microsoft to deliver 25,000 tons of permanent carbon dioxide removal to the tech giant starting in 2027, when the startup’s first commercial project is expected to come online. As a part of the deal, Arbor will also generate 5 megawatts of clean electricity per year, enough to power about 4,000 U.S. homes. And just a few days ago, the Department of Energy announced that Arbor is one of 11 projects to receive a combined total of $58.5 million to help develop the domestic carbon removal industry.
Arbor’s current plan is to source biomass from forestry waste, much of which is generated by forest thinning operations intended to prevent destructive wildfires. Hartwig told me that for every ton of organic waste, Arbor can produce about one megawatt hour of electricity, which is in line with current efficiency standards, plus about 1.8 tons of carbon removal. “We look at being as efficient, if not a little more efficient than a traditional bioenergy power plant that does not have carbon capture on it,” he explained.
The company’s carbon removal price targets are also extremely competitive — in the $50 to $100 per ton range, Hartwig said. Compare that to something like direct air capture, which today exceeds $600 per ton, or enhanced rock weathering, which is usually upwards of $300 per ton. “The power and carbon removal they can offer comes at prices that meet nearly unlimited demand,”Mike Schroepfer, the founder of Gigascale Capital and former CTO of Meta, told me via email. Arbor benefits from the fact that the electricity it produces and sells can help offset the cost of the carbon removal, and vice versa. So if the company succeeds in hitting its cost and efficiency targets, Hartwig said, this “quickly becomes a case for, why wouldn’t you just deploy these everywhere?”
Initial customers will likely be (no surprise here) the Microsofts, Googles and Metas of the world — hyperscalers with growing data center needs and ambitious emissions targets. “What Arbor unlocks is basically the ability for hyperscalers to stop needing to sacrifice their net zero goals for AI,” Kolster told me. And instead of languishing in the interminable grid interconnection queue, Hartwig said that providing power directly to customers could ensure rapid, early deployment. “We see it as being quicker to power behind-the-meter applications, because you don’t have to go through the process of connecting to the grid,” he told me. Long-term though, he said grid connection will be vital, since Arbor can provide baseload power whereas intermittent renewables cannot.
All of this could serve as a much cheaper alternative, to say, re-opening shuttered nuclear facilities, as Microsoft also recently committed to doing at Three Mile Island. “It’s great, we should be doing that,” Kolster said of this nuclear deal, “but there’s actually a limited pool of options to do that, and unfortunately, there is still community pushback.”
Currently, Arbor is working to build out its pilot plant in San Bernardino, California, which Hartwig told me will turn on this December. And by 2030, the company plans to have its first commercial plant operating at scale, generating 100 megawatts of electricity while removing nearly 2 megatons of CO2 every year. “To put it in perspective: In 2023, the U.S. added roughly 9 gigawatts of gas power to the grid, which generates 18 to 23 megatons of CO2 a year,” Schroepfer wrote to me. So having just one Arbor facility removing 2 megatons would make a real dent. The first plant will be located in Louisiana, where Arbor will also be working with an as-yet-unnamed partner to do the carbon storage.
The company’s carbon credits will be verified with the credit certification platform Isometric, which is also backed by Lowercarbon and thought to have the most stringent standards in the industry. Hartwig told me that Arbor worked hand-in-hand with Isometric to develop the protocol for “biogenic carbon capture and storage,” as the company is the first Isometric-approved supplier to use this standard.
But Hartwig also said that government support hasn’t yet caught up to the tech’s potential. While the Inflation Reduction Act provides direct air capture companies with $180 per ton of carbon dioxide removed, technology such as Arbor’s only qualifies for $85 per ton. It’s not nothing — more than the zero dollars enhanced rock weathering companies such as Lithos or bio-oil sequestration companies such as Charm are getting. “But at the same time, we’re treated the same as if we’re sequestering CO2 emissions from a natural gas plant or a coal plant,” Hartwig told me, as opposed to getting paid for actual CO2 removal.
“I think we are definitely going to need government procurement or involvement to actually hit one, five, 10 gigatons per year of carbon removal,” Hartwig said. Globally, scientists estimate that we’ll need up to 10 gigatons of annual CO2 removal by 2050 in order to limit global warming to 1.5 degrees Celsius. “Even at $100 per ton, 10 gigatons of carbon removal is still a pretty hefty price tag,” Hartwig told me. A $1 trillion price tag, to be exact. “We definitely need more players than just Microsoft.”
New research out today shows a 10-fold increase in smoke mortality related to climate change from the 1960s to the 2010.
If you are one of the more than 2 billion people on Earth who have inhaled wildfire smoke, then you know firsthand that it is nasty stuff. It makes your eyes sting and your throat sore and raw; breathe in smoke for long enough, and you might get a headache or start to wheeze. Maybe you’ll have an asthma attack and end up in the emergency room. Or maybe, in the days or weeks afterward, you’ll suffer from a stroke or heart attack that you wouldn’t have had otherwise.
Researchers are increasingly convinced that the tiny, inhalable particulate matter in wildfire smoke, known as PM2.5, contributes to thousands of excess deaths annually in the United States alone. But is it fair to link those deaths directly to climate change?
A new study published Monday in Nature Climate Change suggests that for a growing number of cases, the answer should be yes. Chae Yeon Park, a climate risk modeling researcher at Japan’s National Institute for Environmental Studies, looked with her colleagues at three fire-vegetation models to understand how hazardous emissions changed from 1960 to 2019, compared to a hypothetical control model that excluded historical climate change data. They found that while fewer than 669 deaths in the 1960s could be attributed to climate change globally, that number ballooned to 12,566 in the 2010s — roughly a 20-fold increase. The proportion of all global PM2.5 deaths attributable to climate change jumped 10-fold over the same period, from 1.2% in the 1960s to 12.8% in the 2010s.
“It’s a timely and meaningful study that informs the public and the government about the dangers of wildfire smoke and how climate change is contributing to that,” Yiqun Ma, who researches the intersection of climate change, air pollution, and human health at the Yale School of Medicine, and who was not involved in the Nature study, told me.
The study found the highest climate change-attributable fire mortality values in South America, Australia, and Europe, where increases in heat and decreases in humidity were also the greatest. In the southern hemisphere of South America, for example, the authors wrote that fire mortalities attributable to climate change increased from a model average of 35% to 71% between the 1960s and 2010s, “coinciding with decreased relative humidity,” which dries out fire fuels. For the same reason, an increase in relative humidity lowered fire mortality in other regions, such as South Asia. North America exhibited a less dramatic leap in climate-related smoke mortalities, with climate change’s contribution around 3.6% in the 1960s, “with a notable rise in the 2010s” to 18.8%, Park told me in an email.
While that’s alarming all on its own, Ma told me there was a possibility that Park’s findings might actually be too conservative. “They assume PM2.5 from wildfire sources and from other sources” — like from cars or power plants — “have the same toxicity,” she explained. “But in fact, in recent studies, people have found PM2.5 from fire sources can be more toxic than those from an urban background.” Another reason Ma suspected the study’s numbers might be an underestimate was because the researchers focused on only six diseases that have known links to PM2.5 exposure: chronic obstructive pulmonary disease, lung cancer, coronary heart disease, type 2 diabetes, stroke, and lower respiratory infection. “According to our previous findings [at the Yale School of Medicine], other diseases can also be influenced by wildfire smoke, such as mental disorders, depression, and anxiety, and they did not consider that part,” she told me.
Minghao Qiu, an assistant professor at Stony Brook University and one of the country’s leading researchers on wildfire smoke exposure and climate change, generally agreed with Park’s findings, but cautioned that there is “a lot of uncertainty in the underlying numbers” in part because, intrinsically, wildfire smoke exposure is such a complicated thing to try to put firm numbers to. “It’s so difficult to model how climate influences wildfire because wildfire is such an idiosyncratic process and it’s so random, ” he told me, adding, “In general, models are not great in terms of capturing wildfire.”
Despite their few reservations, both Qiu and Ma emphasized the importance of studies like Park’s. “There are no really good solutions” to reduce wildfire PM2.5 exposure. You can’t just “put a filter on a stack” as you (sort of) can with power plant emissions, Qiu pointed out.
Even prescribed fires, often touted as an important wildfire mitigation technique, still produce smoke. Park’s team acknowledged that a whole suite of options would be needed to minimize future wildfire deaths, ranging from fire-resilient forest and urban planning to PM2.5 treatment advances in hospitals. And, of course, there is addressing the root cause of the increased mortality to begin with: our warming climate.
“To respond to these long-term changes,” Park told me, “it is crucial to gradually modify our system.”
On the COP16 biodiversity summit, Big Oil’s big plan, and sea level rise
Current conditions: Record rainfall triggered flooding in Roswell, New Mexico, that killed at least two people • Storm Ashley unleashed 80 mph winds across parts of the U.K. • A wildfire that broke out near Oakland, California, on Friday is now 85% contained.
Forecasters hadn’t expected Hurricane Oscar to develop into a hurricane at all, let alone in just 12 hours. But it did. The Category 1 storm made landfall in Cuba on Sunday, hours after passing over the Bahamas, bringing intense rain and strong winds. Up to a foot of rainfall was expected. Oscar struck while Cuba was struggling to recover from a large blackout that has left millions without power for four days. A second system, Tropical Storm Nadine, made landfall in Belize on Saturday with 60 mph winds and then quickly weakened. Both Oscar and Nadine developed in the Atlantic on the same day.

The COP16 biodiversity summit starts today in Cali, Colombia. Diplomats from 190 countries will try to come up with a plan to halt global biodiversity loss, aiming to protect 30% of land and sea areas and restore 30% of degraded ecosystems by 2030. Discussions will revolve around how to monitor nature degradation, hold countries accountable for their protection pledges, and pay for biodiversity efforts. There will also be a big push to get many more countries to publish national biodiversity strategies. “This COP is a test of how serious countries are about upholding their international commitments to stop the rapid loss of biodiversity,” said Crystal Davis, Global Director of Food, Land, and Water at the World Resources Institute. “The world has no shot at doing so without richer countries providing more financial support to developing countries — which contain most of the world’s biodiversity.”
A prominent group of oil and gas producers has developed a plan to roll back environmental rules put in place by President Biden, The Washington Post reported. The paper got its hands on confidential documents from the American Exploration and Production Council (AXPC), which represents some 30 producers. The documents include draft executive orders promoting fossil fuel production for a newly-elected President Trump to sign if he takes the White House in November, as well as a roadmap for dismantling many policies aimed at getting oil and gas producers to disclose and curb emissions. AXPC’s members, including ExxonMobil, ConocoPhillips, and Hess, account for about half of the oil and gas produced in the U.S., the Post reported.
A new report from the energy think tank Ember looks at how the uptake of electric vehicles and heat pumps in the U.K. is affecting oil and gas consumption. It found that last year the country had 1.5 million EVs on the road, and 430,000 residential heat pumps in homes, and the reduction in fossil fuel use due to the growth of these technologies was equivalent to 14 million barrels of oil, or about what the U.K. imports over a two-week span. This reduction effect will be even stronger as more and more EVs and heat pumps are powered by clean energy. The report also found that even though power demand is expected to rise, efficiency gains from electrification and decarbonization will make up for this, leading to an overall decline in energy use and fossil fuel consumption.

The world’s sea levels are projected to rise by more than 6 inches on average over the next 30 years if current trends continue, according to a new study published in the journal Nature. “Such rates would represent an evolving challenge for adaptation efforts,” the authors wrote. By examining satellite data, the researchers found that sea levels have risen by about .4 inches since 1993, and that they’re rising faster now than they were then. In 1993 the seas were rising by about .08 inches per year, and last year they were rising at .17 inches per year. These are averages, of course, and some areas are seeing much more extreme changes. For example, areas around Miami, Florida, have already seen sea levels rise by 6 inches over the last 31 years.
“As the climate crisis grows more urgent, restoring faith in government will be more important than ever.” –Paul Waldman writing for Heatmap about the profound implications of America becoming a low-trust society.
