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.

Any version of the future — even one under Trump — includes bits of the Inflation Reduction Act.
We passed a major milestone over the weekend: the one-year anniversary of President Trump’s One Big Beautiful Bill Act. That piece of legislation — which curtailed the wind and solar tax credits, ended incentives for electric vehicle buyers, and terminated a lot of green industrial policy — was signed into law on July 4, 2025. It also formally ended the era of decarbonization and climate policy experimentation that began when the United States passed the Inflation Reduction Act roughly three years earlier.
Now we’re far enough out to begin assessing the Trump law’s impact. And a fascinating new report, published today by the MIT Center for Energy and Environmental Policy Research, argues that the damage … is not as bad as one might fear — at least in the electricity sector.
The power sector has retained most of the quantifiable benefits associated with Biden’s climate law and Environmental Protection Agency rules, the new report asserts, and about two-thirds of the reductions in heat-trapping pollution expected under Biden’s policies will still happen under Trump’s. The report is called “Glass Half Full,” but its author, Lily Bermel, told me that her own conclusions went even further: “It’s not barely half full,” she said. “It’s like three-quarters full.”
We had the exclusive on the new report at Heatmap — check out our full story for more coverage, including interviews with critics of the analysis. Bermel also joined me on our Shift Key podcast to discuss her findings and what they suggest for the future of climate policy.
But in this more discursive space, I want to address head-on a question I think Bermel’s report raises: Was the Inflation Reduction Act worth it? If two-thirds of the emissions cuts expected under President Biden's policies are going to happen anyway (at least from the power sector), what was the point of those policies?
I posed this question directly to Bermel. She pointed me to a different source of MIT data: the Clean Investment Monitor, which tracks clean energy and industry investment in the United States across a range of sectors. That data shows that wind, solar, and storage investment did increase in the United States after the IRA passed, she said. “What the IRA did for wind and solar was good and impactful, but ultimately no longer necessary and worth the bang for buck,” she told me. (She added that the law’s other policies — such as its incentives for “clean firm” power plants such as geothermal that can run all day — did not go far enough.)
Ben King, a director at the Rhodium Group (which collaborates with MIT on the Clean Investment Monitor data), made another point when we chatted about the MIT report over the weekend. The new report compares visions of what the energy system will look like after Trump’s policies and Biden’s policies. But both of those scenarios contain a lot of the IRA’s policies, he said, because the solar and wind tax credits remain available in some form until the end of this decade. There simply is no version of the future that doesn’t have a lot of the IRA in it.
And that should, perhaps, reframe how we compare the emissions trajectories under Trump’s and Biden’s policies. It might sound like good news that 67% of the emissions cuts expected under Biden’s policies could still materialize under Trump’s. But it might also invite a certain nihilism — if most of the cuts were going to happen anyway, why did we have a big political fight over climate policy in the first place?
So it’s worth stating clearly that any fight over emissions or climate policy is partly about the emissions cuts that have not happened yet. Had the Inflation Reduction Act’s tax credits — or the EPA’s climate rules — been preserved, then emissions cuts might have gone even deeper than we once anticipated. In this way, there is always something proleptic about discussing emissions policy — really, you are trying to secure additional emissions reductions.
To put this another way, Bermel’s model suggests that the United States will build the same amount of offshore wind under Trump’s policies as it would under Biden’s (about 6 gigawatts). That happens, she said, because offshore wind is driven by state policy as much if not more than federal policy — and the state policy environment was souring even before Trump took office. But had Kamala Harris won in 2024, then Trump’s war on wind would never have happened, and states may have worked harder to salvage their offshore wind investments — or gone on to build even more.
There is no world, in other words, where Biden’s policies would have stood alone. Their success was always provisional, and their potential victory was always an invitation to further gains.

Current conditions: Super Typhoon Bavi is slamming into Guam and the Northern Mariana Islands as the equivalent of a Category 5 hurricane, with sustained wind speeds topping 178 miles per hour • The record-shattering heat dome over the central and eastern United States is easing and shifting westward until mid July • In Europe, however, the heat is continuing, with temperatures hitting 108 degrees Fahrenheit in southern Spain over the weekend.
America’s next nuclear reactor is coming to life via resurrection. For the past two years, Holtec International has been working to bring the single reactor at the decommissioned Palisades nuclear plant in western Michigan back into service. It would be the first time in U.S. history that a permanently shuttered nuclear plant came back online. If successful, a growing list of projects are lining up to follow in Palisades’ footsteps. On Friday, Holtec announced that the Palisades crew had completed “the last of the major projects,” marking a “watershed moment” in the restoration effort. “We’re now focused on safely executing the remaining testing, verification, and operational readiness activities required before startup,” Michael Schultheis, Holtec’s vice president of the plant, said in a statement. “The plant is coming back together, and the professionalism and dedication demonstrated by our workforce continue to move the project forward.”
The news came just days after the U.S. District Court for the Western District of Michigan dismissed a lawsuit challenging the procedure by which the Nuclear Regulatory Commission approved Palisades’ restart. Started under the Biden administration, the revival project was one of the first the Trump administration allowed to move forward after taking office, part of a broader effort by the Department of Energy to spur a resurgence of reactor construction in the U.S.
Last week, the U.S. Court of Appeals for the Ninth Circuit blocked a challenge to California’s rules on emissions from industrial boilers, the latest legal victory for local regulations on planet-heating pollution from buildings. In 2024, the South Coast Air Quality Management District, the air pollution agency in charge of broad swaths of Southern California, set new restrictions on smog-causing nitrogen oxide from industrial boilers, appliances that either burn a fossil fuel such as gas or oil or use electricity to heat up water. The policy — which would slash the equivalent of half the nitrogen oxide produced by every car in Los Angeles combined — is part of the state’s long-standing effort to curb pollution. It’s not the only win for the fight to curb emissions from buildings. Since 2024, federal courts have repeatedly upheld local and state authority to regulate pollution from buildings in New York, Maryland, and Washington, D.C.
On Thursday, meanwhile, the Trump administration proposed a new rule to gut money-saving standards for appliances nationwide. “While the agency portrayed the move as bringing an end to appliance standards writ large, that is not, in fact, what it is doing,” Heatmap’s Emily Pontecorvo wrote last week. “The proposal would update the DOE’s so-called ‘Process Rule,’ which governs how the agency develops standards, adding onerous requirements that will make it much more difficult to make any changes at all.” When I spoke to the American Council for an Energy-Efficient Economy about the changes, the advocacy group told me the proposal would set minimum savings thresholds below which the new rule wouldn’t find federal support. It would also add a mandatory 180-day waiting period between before proposing new appliance standards based on novel testing procedures, require the Energy Department to show deference to industry-established standards, and force regulators to carry out extra analyses and rulemaking processes before enacting new rules.
Senator Angus King, the independent from Maine who caucuses with the Democrats, has urged the Federal Energy Regulatory Commission to reject the proposed utility megamerger between NextEra Energy and Dominion Energy. In a letter last week to the agency, King said the combination of the two giants risked putting too much power in the hands of one company. “The combination would create the largest electric utility in the United States, concentrating an unprecedented mix of merchant generation, rate-based generation, and transmission assets in the hands of a single company with a documented record of using its market position and political resources to suppress competition that threatens its merchant revenues,” King said in the letter, according to Utility Dive. Specifically, he cited NextEra’s lobbying to derail the New England Clean Energy Connect project in 2021, a transmission line to connect the Northeast’s grid to the almost entirely renewable hydroelectric system in Quebec.

Last week, the Environmental Protection Agency put out new regulatory guidance on the president’s “freedom to fix” agenda, reminding automakers of their “long-standing legal obligation to release the service information, training information, and tools necessary to diagnose and repair vehicles,” even if the driver could use what they learn to tamper with the emissions controls. Meanwhile, on Friday, President Donald Trump announced that he’d pardoned six people “who were persecuted by the Biden administration” and were either in prison or headed there for violating Clean Air Act prohibitions against rigging the vehicles’ emissions control systems. “While I know this sounds ridiculous, it is nevertheless a fact, and part of the Weaponization and Stupidity that our Country had to endure during four long years of Sleepy Joe Biden,” he wrote in a post on his Truth Social platform. “I AM SETTING THEM ALL FREE, RIGHT NOW!”
In non-emitting vehicle news, Rivian is eyeing a better sales year than expected. While the electric automaker previously said it would ship between 62,000 and 67,000 vehicles this year, it told investors on Thursday that it now expects to deliver between 65,000 and 70,000 vehicles, in what TechCrunch called “a small but potentially meaningful bump.” The announcement came the same week BYD crushed Tesla’s deliveries yet again, as I told you in my last newsletter.

Back in March, I told you that Chile’s most right-wing president since the fall of dictator Augusto Pinochet could take the country’s budding green hydrogen business in a different direction. Now President José Antonio Kast is doing just that. Last week, Chile’s state-owned Production Development Corporation, known by its Spanish acronym CORFO, announced plans to refocus the country’s strategy for green hydrogen on domestic use rather than exports, Hydrogen Insight reported.
China, as I have reported for you many times before, is going hard on green hydrogen, especially since the Iran War forced Beijing to ramp up efforts to find alternatives to imported fossil fuels. Here’s yet another data point: China just laid out plans to build the world’s largest green hydrogen plant using solid-oxide electrolyzers, which operate at higher temperatures. The facility will also produce, methanol, which uses hydrogen as a key ingredient. At peak capacity, the facility in rural Gansu province will produce 100,000 metric tons of renewable methanol per year for use in international shipping. Meanwhile, Spain is investing nearly $21 million into grants for hydrogen projects as the country seeks to make use of its booming solar industry. As I wrote last week, the surge in solar panels is creating problems for Spain, since its grid can’t handle all that power during peak daytime hours. Funneling that electricity into electrolyzers to make molecules that can be cleanly burned later may offer a solution.
Last month, I told you about a catchier term for the very small-scale solar panels being legalized to go on windowsills and balconies, opening the door to more apartment dwellers generating a small share of electricity themselves. That term, which I first read in Inside Climate News, is “guerilla solar.” Well, that solar rebel mindset is coming to the “Live Free or Die” state. On Thursday, New Hampshire Governor Kelly Ayotte, a Republican, put out a list of 74 bills she signed into law before Fourth of July weekend. Among them was SB-540, legalizing plug-in solar panels. The law will take effect on July 27, according to PluginSolarUS, an advocacy group.
Rob talks with Columbia’s Lily Bermel about where climate policy should go next.
Wait, is the climate policy landscape … in better shape than it looks?
Just over a year ago, President Trump passed the One Big Beautiful Bill Act. It repealed many of the Biden administration’s most aggressive climate policies, including tax credits for solar and wind energy.
Although those policies are gone, the emissions cuts they achieved remain largely intact — at least in the power sector, according to a new study that we’re covering exclusively at Heatmap. Lily Bermel, the report’s author and a visiting fellow at the Columbia Center on Global Energy Policy, argues that at least where energy generation is concerned, the glass is more than “half full.”
On this episode of Shift Key, Lily joins Rob to discuss what we learned from Biden’s big climate law, why it likely never would have achieved its projected emissions declines (at least not without a tremendous transmission buildout), and how studying its legacy changed her mind about policy going forward.

Here is an excerpt from their conversation:
Robinson Meyer: Given that the IRA, in retrospect, in the power sector, kind of resolved any economic issue you would have making a project pencil out and revealed all these non-economic issues that actually constrain development, we are now looking at a political environment where we’re switching from mourning the IRA to saying, okay, what should happen next? And my colleague Emily Pontecorvo recently wrote a story about this question. But I think one of the big questions going forward, especially if Democrats take Congress at the end of this year is, well, should they fight to restore the tax credits? I can even see a world where restoring the tax credits becomes something people insist on to get permitting reform or something.
After writing this report, did you come to the conclusion that Democrats should restore the wind and solar tax credits? Is that the most urgent priority for climate policy?
Lily Bermel: In writing this report, I became quite confident that I don’t think it’s worth the bang for buck in restoring those wind and solar tax credits, and instead that the supply side constraints are the real issue that we need to focus on. I did this lag analysis where if you take a given year, say 2031, and you see that the IRA trajectory would have deployed like more than 300 gigawatts of solar, how many years later would the [OBBBA] scenario do that? There’s only a two and a half-year lag, or gap. And so in restoring the clean energy tax credits, you are only buying back two and a half years’ worth of deployment, which, at least for me, was a lot smaller than I had thought.
Meanwhile, both scenarios have a literal cap in them about how much they can build and how fast they can build it. So even if you buy back that little two and a half-year average annual lag, you’re going to run up to the exact same ceiling. So restoring the tax credits brings you closer to that ceiling, while permitting reform will completely lift the ceiling and be a rising tide that lifts all boats.
