The entire state of Florida may end up on the hook for damage caused by Hurricane Idalia.
That’s because the state-run insurance company, Citizens, has hundreds of thousands of policies in the area that could be hit by the storm. The most recent National Hurricane Center forecast projects the largest storm surge just north of the heavily populated Tampa Bay area in counties where Citizens has over half the market. The center is also expecting high winds from Tampa north all the way to the state’s Big Bend region, and unlike many private insurers in the state, Citizens is willing to cover wind damage.
Citizens is designed to be backup for Floridians if they can’t get private insurance for their homes and commercial property. As more and more insurance companies leave the state or go out of business, the company has massively expanded its reach over the state’s insurance market. In 2023, Citizens expects to have 1.7 million clients with $5.1 billion in premiums, compared to under 500,000 policyholders and $877 million in premiums in 2019, according to the company’s budget report.
“The difference for this storm of a few degrees is billions of dollars to Citizens,” Jeff Brandes, a former Florida state senator and president of the Florida Policy Project, told me. If it hits Pasco or Hernando counties head-on, Brandes said, the resulting insurance claims could exhaust Citizens’ current surplus and force it to issue “special assessments” — essentially one-time bills — on the state’s policyholders, including drivers. Citizens has over 50% of the property insurance market in the two counties north of Tampa Bay, according to Brandes, meaning that substantial storm damage could incur large losses for Citizens.

Florida’s domestic property insurers have been losing money on underwriting — the difference between premiums collected and claims paid — since 2016, according to the state’s Office of Insurance Regulation. Earlier this year, another Florida insurer, United Property & Casualty Insurance Company, was declared insolvent. Farmers said in July that it would leave the state, one of several insurers to stop doing business there or go out of business entirely.
The combination of high risk from storms and an increasingly uncompetitive insurance market has led to some of the highest home insurance premiums in the nation. In Hillsborough County, homeowners pay an average premium of $2,752, while in Miami-Dade, it’s $5,665.
These high costs are driven by a combination of Florida’s, especially the coasts’, high risk of storm damage to property, and its uniquely litigious environment, which the Florida state government has tried to reform.
Citizens, however, is unlikely to face insolvency because it has an immense backstop: Floridians. If any of the company’s separate accounts are overdrawn (they’re scheduled to be combined early next year), the company can issue assessments to make up the difference.
“A devastating storm or series of smaller storms could cause a deficit in one or more account, leaving Citizens without enough money to pay all claims. If this happens, Florida law requires Citizens to charge a series of assessments until the deficit is paid,” according to the company.
The first level of assessments goes to Citizens policyholders, then a 2 percent surcharge on the premiums paid by private insurance policyholders for the company’s Coastal Account which provides coverage in specified high risk areas. The third level of assessments goes to both private and Citizens policyholders — including home and auto insurance policyholders — until the accounts are made solvent.
“Emergency Assessments can be up to 10% per account per year for each of Citizens’ three accounts. It is levied on both Citizens and non-Citizens policyholders for as many years as necessary until the deficit is resolved,” according to Citizens.
“They have this incredible assessment base,” Brandes told me. “If someone is paying $3,000 [in annual premiums], they can force you to write another for $1,200 or $1,300. Imagine people’s shock when that shows up at their door.”
Earlier this year, Citizens reported that “due to Hurricane Ian, Citizens’ financial resources have been significantly depleted,” and that its surplus had declined to just under $5 billion. This could mean that Florida policyholders could be on the hook for the state-run company: “If Florida is impacted by a storm or series of storms in 2023, Citizens will need to rely on its assessment capability and/or post‐event financing to meet its policyholder obligations,” Citizens said in the report.
“You see massive amount of socializing risk [in a state] that doesn’t want to talk about socialism,” Brandes said. “We’re the free state of Florida except for our largest liability — Citizens — which we are happy to subsidize.”

France’s deadliest heat wave since 2003 killed more than 2,700 people — and possibly as many as 5,700.
More than 5,700 excess deaths were recorded in France during this summer’s record-breaking heat wave, the country’s health agency announced today. That makes the event — which ran, by the official reckoning, from June 17 to July 2 — the country’s deadliest heat wave in more than 20 years.
That’s in line with other estimates we’ve heard. EuroMOMO, a network of European public health agencies that track excess mortality, found that the continent saw more than 10,000 excess deaths during the same period. Roughly 90% of those victims were older than 65, it said. (France’s cohort seems similar: Adults older than 75 made up about two-thirds of the victims, the government said.)
These numbers are staggering — and much larger than some astute Heatmap readers might anticipate. If you read my colleague Jeva Lange’s piece on why it’s so hard to estimate heat deaths last week, she cited a much smaller estimate: Roughly 2,700 died in France during the most recent heat wave. That tally came from Christopher Callahan, an Indiana University scientist who studies climate change’s economic and social costs.
Why is there such a gap between the figures? I emailed Callahan to find out. He shared a few thoughts. First, he uses a different (and theoretically more rigorous) method than the French government: “Our approach uses a statistical relationship between temperature and mortality to explicitly quantify how many additional deaths are associated with a given day’s temperature,” he wrote. “France’s report of excess deaths is just based on how many more people died in late June compared to previous Junes - but we don’t know if those people died because of the heat or some other factor.” (Carbon Brief recently published a Q&A on these varying approaches.)
That might mean his estimate is right, in which case France has misidentified roughly nearly 3,000 deaths. But it could also mean his model, which is trained on data from 2004 to 2019, is “missing something,” he said, like a post-Covid change to public health risk. Last year, Callahan and his colleagues used a similar model to estimate deaths from France’s worst-ever heatwave, a 2003 episode that overwhelmed morgues and killed about 16,000 people. Even 23 years ago, global warming helped make that disaster larger than it needed to be: Some 6,000 of those deaths were due to climate change, their paper found.
Either estimate of the 2026 heat wave, of course, is shattering. As Jeva wrote, even the lower figure would mean the 2026 heat wave killed as many people as died in three years of French homicides. But the divergence in estimates tells us something else too: Even as climate change breaks records and alters our world, we’re never going to quite agree on where it ends and normal randomness begins.
The AI data center boom does not seem close to ending. Google’s parent company, Alphabet, announced its second quarter results this evening, and it beat Wall Street’s expectations, nearly quadrupling its profit on a year-over-year basis. Among the drivers: Its cloud business grew 82% compared to the same quarter last year. (As I’ve written, that rapid growth is helping to turn Alphabet and other hyperscalers into light industrial firms.)
The company’s AI bets seem to be paying off so far — so Google is now planning on spending even more on data centers, energy infrastructure and AI development this year than it once anticipated. It raised its estimates of 2026 capital expenditure to $195 billion to $205 billion, which is above earlier projections and twice as much as it spent in the same category last year. 2027 could be even bigger, it signaled. The company’s shares fell slightly on the news in after-hours trading, but from an energy and climate wonk perspective, the message is clear: For now, the AI demand surge transforming the power sector — and the real economy — continues to chug along.
