Some 20 million Americans woke up on Monday to the news that they have just one full day to prepare for Tropical Storm Idalia, which is expected to strengthen into the first major U.S. hurricane of the season this week. The “nasty” weather is likely to begin in Florida on Tuesday night, ahead of landfall on Wednesday morning.
Though meteorologists had been carefully watching Idalia — née Invest 93L — since at least Wednesday, the storm’s rapid intensification has taken even forecasters by surprise. Idalia had grown into a tropical depression by Saturday, fully a day or two ahead of schedule, only for a NOAA reconnaissance flight on Sunday to discover it was already gusting at 65-mile-per-hour — enough for it to promptly be given status as a named tropical storm. Newly minted Idalia then intensified even further overnight on Sunday. New models show it will grow from a Category 1 hurricane on Monday night into a full-blown Category 3 hurricane “just 24 hours later.”
Needless to say, Idalia has everyone jumpy. Part of that is superstition: Storms with names that start with the letter "I" are the most frequently retired. But it also looks like Idalia is the real deal: “The number one rule of this column is not to pull the fire alarm unless there is a fire,” meteorologist Ryan Truchelut wrote for his newsletter WeatherTigeron Sunday. “Idalia is a fire. I’m pulling the alarm.” Florida Governor Ron DeSantis stressed similar urgency in an early morning news conference on Monday: “This is going to be a major hurricane,” he said, adding, “Floridians, you need to be executing your plans now. Late Tuesday, early Wednesday, it’s going to start to get really nasty.”
In an age of sophisticated weather modeling, the rapid intensification of Idalia feels like the hurricane snuck up on us. Sure enough, conditions like the record-warm Gulf of Mexico water temperatures — which Axiosdescribes as “the equivalent of a powder keg for hurricane energy” — have some experts cautioning we might not have exhausted all of Idalia’s surprises just yet.
Here are some of the most concerning variables as the storm approaches the coast.
The biggest reason to watch Idalia carefully is that it’s churning over some seriously deep warm water. The Gulf of Mexico has averaged a temperature of about 88 degrees Fahrenheit this month, which is 2.6 degrees above normal. For context, just a 1-degree rise in ocean temperature can bump up a hurricane’s winds by 15 to 20 miles per hour, meaning Idalia is essentially running on “rocket fuel,” Yale Climate Connections warns.
So we know Idalia will have ample fuel, but we don’t quite know what that means yet, since “storm intensity forecasts are notoriously hard to make, especially more than a day in advance,” as Andrew Freedman writes for Axios. But deadly Hurricanes Ian and Michael also rapidly intensified over warm waters, and “Idalia is likely to encounter waters even hotter” than they did.
Though climate change caused by human activities doesn’t increase the frequency of hurricanes, warmer oceans mean the ones that form tend to be more intense, slow, and destructive. Earlier this month, the National Hurricane Center updated its 2023 outlook from a “near-normal” season to an “above-normal” season, anticipating two to five major hurricanes. Oh, and in case you were wondering: The Atlantic, where Hurricane Franklin is chugging toward Bermuda, is really hot, too.
The biggest threat to life from to-be Hurricane Idalia looks like it will be from the storm surge. Though conditions can still worsen — particularly with a storm as seemingly unpredictable and rapidly intensifying as this one — emergency officials aren’t suggesting people in the storm’s path flee altogether, just that they get to higher grounds ASAP. “Evacuate tens of miles, not hundreds of miles,” the Executive Director of the Florida Division of Emergency Management Kevin Guthrie said.
One reason for the storm surge danger is because of the region’s “bathymetry,” meteorologist Matthew Cappucci tweeted. That is to say, the slope of the sea floor can lead to water “piling” up against the coast and being pushed inland. On top of that, emergency officials are closely watching the tides; as Florida Today notes, this week’s supermoon is making high tides even higher.
Hurricanes that approach the west coast of Florida can be “notoriously challenging” to track because of their angle, Yale Climate Connections writes. “[O]nly a slight nudge in trajectory to the right or left can change the landfall location by 50 or 100 miles.”
Idalia’s trajectory will become increasingly clear as it moves closer and closer to shore, but in the meantime, emergency officials are urging everyone both within and without the cone to be prepared for the storm. Notably, the storm surge in particular will impact areas outside of where Idalia directly hits:
One rule of thumb for hurricane season is to always keep half a tank of gas in your car. But on Sunday afternoon, Florida reported contaminated gasoline and diesel had been sold from at least 29 stations in the state in a corridor potentially stretching from Brooksville south to Fort Myers.
The contaminated gas could “increase the chances of drivers getting stranded” while “generators used in the case of storm-related power outages could also be affected,” The Washington Post reports.
All the more reason to know your zone and leave early if necessary, follow evacuation orders promptly (and arrange alternative travel if you’re concerned about your car), and be prepared for flooding.

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.”
On the Cybercab rollout, methane leaks, and Taylor Swift
Current conditions: England just had its one of its worst crop harvests ever due to extreme rainfall last winter • Nevada and Arizona could see record-breaking heat today, while freeze warnings are in effect in four northeastern states • The death toll from Hurricane Milton has climbed to 16.
Tesla unveiled a prototype of its “Cybercab” self-driving robotaxi last night at an investor event in California. The 2-seater vehicle has no steering wheel or pedals, and will feature wireless induction charging. CEO Elon Musk said the vehicle will cost less than $30,000, with the goal of starting production by 2027, depending on regulatory approvals. At the same event, Musk unveiled the autonomous “Robovan,” which can carry 20 people.

A UN expert group agreed this week on some key rules around carbon markets and carbon crediting. This will be a major topic at COP29 next month, where negotiators will be tasked with deciding how countries can use international carbon markets. As the Financial Timesexplained, a carbon market “would allow governments to claim other countries’ emission cuts towards their own climate targets by trading instruments that represent one tonne of carbon dioxide removed or saved from the atmosphere.” The experts this week said projects seeking carbon credits will have to carry out an extensive risk assessment process aimed at flagging and preventing human rights abuses and environmental harm. The assessment will be reviewed by external auditors.
The first detections from Carbon Mapper’s Tanager-1 satellite are in, just two months after the satellite launched. It spotted a 2.5-mile-long methane plume spewing from a landfill in Pakistan, which Carbon Mapper estimates could be releasing 2,600 pounds of methane per hour. It also identified a methane plume in the oilfields of the Permian Basin in Texas, estimated to be releasing 900 pounds of methane hourly. And it found a carbon dioxide plume over a coal-fired power plant in South Africa releasing roughly 1.3 million pounds of CO2 per hour.

In a press release, the company said the observations were “a preview of what’s to come as Carbon Mapper will leverage Tanager-1 to scale-up emissions observations at unprecedented sensitivity across large areas.”
As the cleanup efforts continue in the southeast after back-to-back hurricanes Helene and Milton devastated the region, pop star Taylor Swift announced she is donating $5 million to relief efforts. Specifically she has given money to a national food bank organization called Feeding America. The charity’s CEO said the funds “will help communities rebuild and recover, providing essential food, clean water, and supplies to people affected by these devastating storms.” Last week country music legend Dolly Parton said she personally donated $1 million to the Mountain Ways Foundation, and then another $1 million through her Dollywood foundation.
AccuWeather estimated that Milton caused up to $180 billion in economic losses, and Helene caused up to $250 billion in losses. Two rapid attribution studies out of Imperial College London found that human-caused climate change could be credited for roughly half the economic damages from the storms. “This analysis clearly shows that our failure to stop burning fossil fuels is already resulting in incredible economic losses,” said Dr. Friederike Otto, co-founder of World Weather Attribution.
In Rhode Island, the Providence City Council passed an amendment this week that bans the construction of new gas stations “while prioritizing the development and installation of electric vehicle charging stations.” That would make Providence the first city on the East Coast to enact such a ban. Mayor Brett Smiley could veto it, but the city council could override a veto with a two-thirds majority, The Boston Globereported. Several towns in California have already banned new gas pumps.
Chiquita has developed a new hybrid banana variety it says is resistant to some fungal diseases that have threatened the future of America’s most popular fruit. The variety is called Yelloway 1.

It’s known as the 50% rule, and Southwest Florida hates it.
After the storm, we rebuild. That’s the mantra repeated by residents, businesses and elected officials after any big storm. Hurricane Milton may have avoided the worst case scenario of a direct hit on the Tampa Bay area, but communities south of Tampa experienced heavy flooding just a couple weeks after being hit by Hurricane Helene.
While the damage is still being assessed in Sarasota County’s barrier islands, homes that require extensive renovations will almost certainly run up against what is known as the 50% rule — or, in Southwest Florida, the “dreaded 50% rule.”
In flood zone-situated communities eligible to receive insurance from the National Flood Insurance Program, any renovations to repair “substantial damage” — defined as repairs whose cost exceeds 50% of the value of the structure (not the land, which can often be quite valuable due to its proximity to the water) — must bring the entire structure “into compliance with current local floodplain management standards.” In practice, this typically means elevating the home above what FEMA defines as the area’s “base flood elevation,” which is the level that a “100-year-flood” would reach, plus some amount determined by the building code.
The rule almost invites conflict. Because just as much as local communities and homeowners want to restore things to the way they were, the federal government doesn’t want to insure structures that are simply going to get destroyed. On Siesta Key, where Milton made landfall, the base flood elevation ranges from 7 feet to 9 feet, meaning that elevating a home to comply with flood codes could be beyond the means — or at least the insurance payouts — of some homeowners.
“You got a 1952 house that’s 1,400 square feet, and you get 4 feet of water,” Jeff Brandes, a former state legislator and president of the Florida Policy Project, told me on Wednesday, explaining how the rule could have played out in Tampa. “That means new kitchens and new bathrooms, all new flooring and baseboards and drywall to 4 or 5 feet.” That kind of claim could easily run to $150,000, which might well surpass the FEMA threshold. “Now all of the sudden you get into the 50% rule that you have the entire house up to current code levels. But then you have to do another half-a-million above what [insurance] paid you.”
Simple probability calculations show that a 100-year flood (which is really a flood elevation that has a 1-in-100 chance of occurring every year) has a more than 25% chance of occurring during the lifetime of a mortgage. If you browse Siesta Key real estate on Zillow, much of it is given a 100% chance of flooding sometime over the course of a 30-year mortgage, according to data analysis by First Street.
Sarasota County as a whole has around 62,000 NFIP policies with some $16.6 billion in total coverage (although more than 80% percent of households have no flood insurance at all). Considering that flood insurance is required in high-risk areas for federally-backed mortgages and for new homeowners insurance policies written by Florida’s state backed property insurer of last resort, Citizens, FEMA is likely to take a close interest in whether communities affected by Milton and Helene are complying with its rules.
If 2022’s Hurricane Ian is any indication, squabbles over the 50% rule are almost certain to emerge — and soon.
Earlier this year, FEMA told Lee County, which includes Fort Myers and Cape Coral, that it was rescinding the discount its residents and a handful of towns within it receive on flood insurance because, the agency claimed, more than 600 homeowners had violated the 50% rule after Hurricane Ian. Following an outcry from local officials and congressional representatives, FEMA restored the discount.
In their efforts to avoid triggering the rule, homeowners are hardly rogue actors. Local governments often actively assist them.
FEMA had initiated a similar procedure in Lee County the year before, threatening to drop homeowners from the flood insurance program for using possibly inaccurate appraisals to avoid the 50% rule before eventually relenting. The Fort Myers News Press reported that the appraisals were provided by the county, which was deliberately “lowering the amount that residents could use to calculate their repairs or rebuilds” to avoid triggering the rule.
Less than a month after Ian swept through Southwest Florida, Cape Coral advised residents to delay and slow down repairs for the same reason, as the rule there applied to money spent on repairs over the course of a year. Some highly exposed coastal communities in Pinellas County have been adjusting their “lookback rules” — the period over which repairs are totaled to see if they hit the 50% rule — to make them shorter so homeowners are less likely to have to make the substantive repairs required.
This followed similar actions by local governments in Charlotte County. As the Punta Gordon Sun put it, “City Council members learned the federal regulation impacts its homeowners — and they decided to do something about it.” In the Sarasota County community of North Port, local officials scrapped a rule that added up repair costs over a five-year period to make it possible for homeowners to rebuild without triggering elevation requirements.
When the 50% rule “works,” it can lead to the communities most affected by big storms being fundamentally changed, both in terms of the structures that are built and who occupies them. The end result of the rebuilding following Helene and Milton — or the next big storm to hit Florida’s Gulf Coast — or the one after that, and so on — may be wealthier homeowners in more resilient homes essentially serving as a flood barrier for everyone else, and picking up more of the bill if the waters rise too high again.
Florida’s Gulf Coast has long been seen as a place where the middle class can afford beachfront property. Elected officials’ resistance to the FEMA rule only goes to show just how important keeping a lid on the cost of living — quite literally, the cost of legally inhabiting a structure — is to the voters and residents they represent.
Still, said Brandes, “There’s the right way to come out of this thing. The wrong way is to build exactly back what you built before.”
