A Q&A with Villanova’s Stephen M. Strader on the legacy of Hurricane Andrew, unsustainable development, and why building codes alone aren’t enough.

In around 12 hours, Hurricane Milton is set to make landfall within miles of Tampa Bay, a region that is home to more than 5 million people. Once a sleepy retirement community, the area has seen a major development boom in recent years fueled by Millennials and Gen Zers seeking the perks of coastal living; it was the 11th fastest-growing city of its size in the U.S. as of this spring and has been expected to continue to grow at nearly twice the rate of the rest of the country over the next five years. A third of those residents, including many of the newcomers, live in low-lying neighborhoods now under urgent evacuation notices due to the threat of “unsurvivable” storm surge, which could rise up to 15 feet.
The development boom that has made Tampa Bay so desirable is also why it’s particularly vulnerable. In an analysis of Hurricane Ian — the most expensive storm in Florida’s history, which struck just south of Milton’s projected track in 2022 — the re-insurance company Swiss Re found that if the storm had struck in the 1970s, it would have caused a third to a half as much damage. Simply put: You can’t adapt your way out of a hurricane problem.
If there is anyone to talk to about the vulnerabilities unique to Tampa Bay, it’s Stephen M. Strader, an associate professor and hazard geographer at Villanova University. Our conversation has been edited and condensed for clarity.
You shared an image on Twitter of the explosive growth in the Tampa Bay area between 1940 and 2024. Why does this make the region vulnerable to a storm like Milton? Is it just about there being more people there?
When we think about disasters, we think of the intersection of three components: a violent event, like what we have with Milton; vulnerability, or what types of people could be in the path, which could be related to racial divides, age, and gender norms; and what a lot of my work focuses on, exposure.
Exposure is just the number of people or things that we care about — businesses, schools, and things like that — that are subject to losses if an event occurs. Florida is a great example of rapid urbanization since the 1900s, and it’s rapid development in a very hazard-prone region.
It can be easy for outsiders to sit back and wonder why anyone would buy a house on the water or on a barrier island near Tampa.
There are a lot of factors that come into play when you think about where we develop and why we develop certain locations. One of the biggest pressures that we see is that it’s desirable land: In the short term, people want to live near the water. It’s beautiful! People don’t think necessarily about the risk that comes with it because they’re too focused on their dream, which is to live near the ocean.
The other side of that is, from an economic standpoint, people see it as an opportunity to have businesses and to build condos. Developers see the land and think, “How much could I buy this for and sell it for with homes on it?” This really started back with Carl Fisher, who was famous for building the Indianapolis Motor Speedway. He was a thrill-seeker, but also a businessman and developer, and he loved to go to South Florida — which is now Miami Beach, and then was swamps and mangroves and not developed at all. And he thought, Hmm, this would be a great place for people to visit for vacations and experiences. He slowly started filling in the wetlands with sand. And that’s the history of Florida's development: It continued because this was very valuable land.
There is a lot of socioeconomic pressure to develop in these areas, but we’re also starting to see it change. Those pressures are lessening because you have insurance industries now and events like this year after year.
There is another issue in Southwest Florida, which is that many of the homes were constructed before building codes were updated, right?
I tend to do a lot more work on the manufactured housing side. Before 1974, all manufactured homes were called mobile homes, and there wasn’t really a standard. Then, in 1974, the United States Department of Housing and Urban Development came in and said, “We need to increase the standards,” and they did.
Fast-forward to 1992 and Hurricane Andrew, and they realized these codes were not strong enough. Many people lived in manufactured homes that were destroyed by Andrew, which was a very windy hurricane. We think hurricanes are wind threats because of Andrew, but hurricanes are water threats, and most deaths occur because of that water. Andrew was the opposite.
Between 1992 and 1994, they updated building codes for manufactured housing, and actually, along the coastline, Florida has some of the strongest codes for manufactured homes in the country. A lot of the areas that will be affected by Milton will have those strong standards. But many homes were also grandfathered in if they were built before that time.
That’s just one type of housing. My guess is that when you have a lot of rapid development since the 1990s — well, I have some questions about structural integrity since building codes can be strong but they might not be followed. And we sometimes don’t know until afterwards. A lot of what is being built are condos or McMansions — it’s basically, How fast can you build them, how cheap can you build them, and how high can you sell them? And they look great until their performance is put into question.
Insurance companies are starting to see this and ask, “How do we retrofit structures?” Structure-wise, though, I think Tampa is in a decent spot. The problem is, the water is so powerful that it’s not going to matter.
What kinds of conversations do you think Floridians should be having about development or potential redevelopment after Milton?
I’m a huge proponent of resisting the urge to build right back — the reason being that’s how you get repetitive losses. The hard part is, with a lot of insurance, if you have it, you only get provisions to build back the way you were. You don’t have the ability to improve. So what I end up telling people is, sometimes these disasters provide an opportunity to assess what we need to do from a planning standpoint. This is unsustainable development, and not just because of hurricanes, but because of rising sea levels and the stress on the environment. And unfortunately, a lot of these developments were built on top of wetlands and marshes and mangroves that used to protect the island areas as natural barriers.
The hard part is that people’s emotions are very strong after disasters, and they immediately want to return to how things were. That’s why you see people picking up the pieces the day after a storm, sometimes even when they’re injured. So we have to resist the urge as a group, and say, maybe this isn’t the time to think about rebuilding here.
Many wetland restoration projects in Florida are doing that very thing: reclaiming the environments that protected people inland. But on the other side you have developers and builders and local economies that rely on people coming to these areas, and that pressures people to come right back. Then you end up with a situation of repetitive losses and that’s why FEMA has been losing money over the years — it’s not so much that we’re putting money toward disasters but that we’re not getting value out of it, because it’s so much more likely for there to be impacts because of that exposure growth. Look at what happened after Helene and what’s going to happen with Milton: We’re splitting resources between the two. But we’re doing the best with the tools we have when there’s pressure on both sides, and considerations both economic and safety.
Is there anything else people should know about the geography of Tampa or the development risk there?
This storm is going to be different than other storms, and that’s because of the direction and intensity of it. The one thing we have to remember is that all that development — and everybody, for the most part, who isn’t 100 years old — has not experienced a hurricane of this magnitude in their life. That means everyone has the cognitive bias to say, “I’ve been through hurricanes before and was fine.” That is probably not going to be the case with this event; no one has been through this before.
What’s worrisome to me is that the trajectory of the hurricane is changing. A subtle shift north or south by 20 miles could mean a big difference for the Tampa region — if you have the right side of the hurricane push water into the Bay, it’s no different than 10 people jumping into a hot tub. The water level goes up and forces all that water into a smaller region, which is going to lead to more storm surge in Tampa Bay, Clearwater, and the St. Pete area. I don’t want to call it a “perfect storm,” but if you push all that water in there, you’re going to flood people in a way that hurricanes they’ve been through before never got close to. And I worry, if it goes south, about Fort Myers and the areas that were hit hard by Hurricane Ian. So it’s multilayered.
The good news that I’ll bring up is that we’re reeling from Helene, which means people have it in their brains about how bad this can be, which is probably causing more people to evacuate than normal. We have a problem with disaster amnesia in places where a hurricane hasn’t happened in a long time so “it’s not going to happen again.” And we forget. I remember Hurricane Katrina and what it did to New Orleans. It still has effects, but the students I’m teaching now weren’t even alive when it hit. These memories are short, and many people in Florida today weren’t there 30 years ago or 20 years ago. The only good thing to come out of Helene is that people are now aware of what can happen.

But this might all be moot thanks to the “major questions doctrine.”
Could President Trump’s expansive interpretation of the International Emergency Economic Powers Act empower a future president to, gasp, tariff carbon intensive goods?
That’s the terrifying prospect Justice Neil Gorsuch, a staunch conservative who often votes in line with Trump and his administration’s positions, raised to Solicitor General D. John Sauer in Wednesday’s oral arguments in the federal court case seeking to throw out Trump’s tariffs.
In a series of questions designed to draw out what limits Sauer thought existed on executive power, Gorsuch asked, “Could the president impose a 50% tariff on gas-powered cars and auto parts to deal with the unusual and extraordinary threat from abroad of climate change?” (This echoed the language of the statute the Solicitor General cited to justify the tariffs.)
“It’s very likely that could be done,” Sauer conceded.
“I think that would have to be the logic of your view,” Gorsuch replied.
“Obviously this administration would say that’s a hoax, this is not a real crisis,” Sauer said.
“I’m sure you would,” Gorsuch said to chuckles.
“But that would be a question for Congress, under our interpretation, not the courts,” Sauer said.
Gorsuch’s questioning touched on the “major questions doctrine,” first propounded in the court’s 2022 opinion in West Virginia v. Environmental Protection Agency. In that case, which resulted in the court striking down the Obama-era Clean Power Plan power plant regulations, the conservative majority argued that “given both separation of powers principles and a practical understanding of legislative intent, the agency must point to ‘clear congressional authorization’ for the authority it claims,” which it claimed the rules lacked.
In a note to clients following the emissions rules case, the white shoe law firm Davis Polk wrote that the majority opinion “does not provide guidance for applying the major questions doctrine in future cases,” but noted that a concurrence authored by Justice Gorsuch “attempted to provide such guidance for future cases.” In said concurrence, Gorsuch wrote that the major questions doctrine could be invoked when the executive branch is dealing with a question of “great political significance” or “a significant portion of the American economy.”
Hmm!
Some progressives flagged this aspect of the tariffs case as it worked its way through the courts, pointing out that it could call into question powers that future presidents may want to use to implement expansive industrial policy, including climate policy. Some of the broader legal arguments against the tariffs, Todd Tucker of the progressive Roosevelt Institute wrote in a brief, “tilt the scales overwhelmingly against progressive priorities.”
“Limits on Trump today will bind future presidents tomorrow. This could include centrists, progressives, MAGA types, or traditional conservatives, who will need or want robust executive tools to address ruinous competitiveness or climate emergencies.”
But in pursuit of their clients’ interests, advocates for striking down the tariffs were more than happy to pick up the thread dropped by Gorsuch to make libertarian-leaning arguments about presidential powers.
“It is simply implausible that in enacting” the International Emergency Economic Powers Act, the law Trump has used to justify his retributive import taxes, “Congress handed the president the power to overhaul the entire tariff system and the American economy in the process, allowing him to set and reset tariffs or any and every product from any and every country at any and all times,” Neal Katyal, the lawyer arguing on behalf of a beer and wine distributor and a longtime figure in Democratic legal circles, said in his oral argument.
Perhaps seeking to appeal to the Republican majority on the court, Katyal returned to Justice Gorsuch’s climate change example, arguing that “if the government wins, another president could declare a ’climate emergency’ and impose huge tariffs without floors or ceilings, as Justice Gorsuch said.”
“My friend’s answer,” Katyal said, referring to Sauer, “is, ‘This administration would declare it a hoax.’ The next president may not quite say that.”
Many legal experts thought that the administration got the worse of the oral arguments and questioning of the attorneys, with conservative Justices Gorsuch and Amy Coney Barrett and Chief Justice John Roberts all asking skeptical questions of Sauer, while Justices Clarence Thomas and Samuel Alito repeatedly threw the White House argumentative lifelines, including, in Alito’s case, suggesting other laws that could justify the tariffs.
Alito even gently mocked Katyal, a Democrat who served as acting solicitor general in the Obama administration, for blatantly using conservative-tinged legal arguments about the scope of executive authority over the economy.
“I wonder if you ever thought that your legacy as a constitutional advocate would be the man who revived the non-delegation argument,” referring to the idea that certain powers are too much akin to lawmaking to delegate to the executive branch, which in theory could vastly restrict the authority of regulators.
But Katyal resisted the implied contradiction and persisted in targeting the right wing of an already conservative Supreme Court.
“Heck yes,” Katyal said. “I think Justice Gorsuch nailed it on the head when saying that when you’re dealing with a statute that is this open-ended — unlike anything we’ve ever seen.”
On Massachusetts’ offshore headwinds, Biden’s gas rules, and Australia’s free power
Current conditions: The Pacific Northwest is getting blasted with winds of up to 70 miles per hour • Heavy snow is coming this week for the higher elevations in New England and upstate New York • San Cristóbal de La Laguna in the Canary Islands saw temperatures surge to 95 degrees Fahrenheit.

Democratic candidates swept to victory in key races with implications for climate change on Tuesday night. In Virginia, Democrat Abigail Spanberger — who vowed to push forward with offshore wind, new nuclear reactors, and fusion energy — seized the governor’s mansion in the first major race to be called after polls closed. In New Jersey, Democrat Mikie Sherrill, who campaigned on building new nuclear plants and pressing the state’s grid operator, PJM Interconnection, to cut electricity prices, trounced her Republican opponent. In New York City, Democrat Zohran Mamdani, who said little about energy during his campaign but came out in the last debate in favor of nuclear power, easily beat back his two rivals for Gracie Mansion. Yet the Georgia Public Service Commission's incumbent Republican Tim Echols lost his race against Democrat Alicia Johnson, a defeat for a conservative who championed construction of the only two nuclear reactors built from scratch in modern U.S. history. In what one expert called a sign of a “seismic shift” on the commission, Peter Hubbard, another Democrat running to flip a seat on the commission, also won.
At a moment when the Trump administration is “disassembling climate policy across the federal government,” Heatmap’s Emily Pontecorvo wrote, “state elections are arguably more important to climate action than ever.”
A federal judge in Washington ruled Tuesday that the Trump administration can reconsider the Biden-era approval of SouthCoast Wind off the coast of Nantucket, Massachusetts. The decision, reported in The New York Times, is a setback for the joint venture between EDP Renewables and Engie, and handed the White House a victory in what we’ve called here the administration’s “total war on wind.” Judge Tanya S. Chutkan of the U.S. District Court for the District of Columbia ruled that the project developers would not “suffer immediate and significant hardship” if the Department of the Interior’s Bureau of Ocean Energy Management were allowed to reevaluate the project’s construction and operation permits.

Meanwhile, the U.S. Court of Appeals for the D.C. Circuit upheld Biden-era Department of Energy efficiency rules for gas-fired residential furnaces and commercial water heaters in a ruling that rejected the gas industry’s challenge on Tuesday. “Overall, we find that DOE’s economic justification analysis and conclusions were robust,” the panel ruled, according to Bloomberg Law. The decision will maintain the status quo of how the agency enforces energy efficiency rules for the appliances. Under standards updated in 2021 and 2023, the Biden-era bureaucrats proposed raising efficiency levels to 95% for furnaces and using condensing model designs to heat water.
White House budget officials pressed the Environmental Protection Agency to expand its rollback of tailpipe regulations this summer as the agency sought to repeal the foundational policy that undergirds federal climate rules, E&E News reported. Documents the green newswire service obtained showed the White House Office of Management and Budget pushed the environmental regulator to weaken limits on vehicular pollution, including soot and smog-forming compounds in addition to planet-heating carbon. The EPA initially pushed back, but the documents revealed the staffers at OMB demanded the agency pursue a more aggressive rollback.
Australia launched a new plan to force energy companies to offer free electricity to households during the day to use excess solar power and push the grid away from coal and gas. The policy, called the “Solar Sharer” plan, aims to take advantage of the country’s vast rooftop solar panels. More than 4 million of Australia’s 10.9 million households have panels, and the capacity has overtaken the nation’s remaining coal-fired power stations. The proposal, the Financial Times reported, would also extend the benefits of distributed solar resources to the country’s renters and apartment dwellers.
For years, nuclear scientists have dreamed of harnessing atomic energy from thorium, potentially shrinking radioactive waste and reducing the risk of weapons proliferation compared to uranium. In the West, that has remained largely a dream. In China, however, researchers are vaulting ahead. This week, Chinese scientists announced a major breakthrough in converting thorium to uranium in a reactor. “This marks the first time international experimental data has been obtained after thorium was introduced into a molten salt reactor, making it the only operational molten salt reactor in the world to have successfully incorporated thorium fuel,” Shanghai Institute of Applied Physics of the Chinese Academy of Sciences said in a statement.
Rob and Jesse touch base with WeaveGrid CEO Apoorv Bhargava.
Data centers aren’t the only driver of rising power use. The inexorable shift to electric vehicles — which has been slowed, but not stopped, by Donald Trump’s policies — is also pushing up electricity use across the country. That puts a strain on the grid — but EVs could also be a strength.
On this week’s episode of Shift Key, Rob and Jesse talk to Apoorv Bhargava, the CEO and cofounder of WeaveGrid, a startup that helps people charge their vehicles in a way that’s better and cleaner for the grid. They chat about why EV charging remains way too complicated, why it should be more like paying a cellphone bill than filling up at a gas station, and how the AI boom has already changed the utility sector.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: In your experience, are consumers willing to make this deal, where they get some money off on their power bill in order to change how their car works? Because it does seem to include a mindset change for people, where they’re going from thinking of their car as a machine — I mean, this is part of the broader transition to EVs. But there’s an even further mindset shift that seems to me like it would be required here, where you go from thinking about your car as a machine that you wholly own — that enables your freedom, that is ready to drive a certain amount of miles at any time — to a machine that enables you to have transportation services but also is one instantiation of the great big cloud of services and digital technologies and commodity energy products that surround us at any time.
Apoorv Bhargava: Yeah, I mean, look, I think we have seen faster adoption rates than any other consumer-side resource participating in energy has. So I feel very good about that. But ultimately, I think of this as a transition to the normal experience for folks who are going through what is a new experience altogether.
Again, similar to my cell phone plan, if this was just offered to me as a standard offering — you buy an EV, your utility offers you a plan, it’s called the EV plan — in the same way that we have EV time-of-use rates, quote-unquote. If you’re just offered an EV plan where it’s exactly the same thing — I’m going to make sure you’re fully charged every night in the way you want it to be charged, with the cleanest, cheapest, most reliable charging possible, and it’s just being taken care of.
I think what’s so hard for most folks to grok, is that the way this experience works is it’s supposed to be completely frictionless, right? You’re really supposed to not think about it. It’s actually only in the few moments where you need to change your 99% behavior to the 1% behavior — where you’re like, Oh, I need to go to the airport, or, Oh, I need to go on a road trip. That’s where you need to think about it. It’s flipped from thermostat management programs where you actually need to think about it actively in the moments where the grid is really strained.
Where we’ve overinvested, in my view —and this is a controversial view — we’ve overinvested in trying to make EVs be like gas stations or like the gas station model. We keep talking about it all the time. We’ve over-talked about range anxiety. The fact of the matter is 80% of charging still happens at home. Even in the long run, 30% of charging will happen in the workplace. 50- plus-percent will happen at home. It’s very little charging that’s gonna happen on fast charging. But we’ve talked so much, ad nauseam, about fast charging that we’ve actually forgotten that underpinning the iceberg of the electrification cost is the grid itself. And never before has the grid been so strained.
