The curious origin of the "climate haven" myth

The term “climate haven” never made much sense. After Hurricane Helene dumped two feet of rain on western North Carolina, many major media outlets marveled at how Asheville, which had been celebrated as a climate haven, had been devastated by a climate-related disaster.

Some in the media later reported accurately that climate havens don’t actually exist. But that still raises the question: Where did this climate haven concept even come from?

Well before humans began putting billions of tons of greenhouse gasses into the atmosphere, entire populations would migrate toward better conditions in search of a place with milder weather or more fertile soil or the absence of drought. Because of its speed and scale, however, human-caused climate change is especially extreme, and everywhere will be impacted by some degree of risk. There is no completely safe haven.

Which is part of how we ended up talking about the idea of climate havens. It’s wishful thinking. At least that’s what several experts told me after Helene laid a path of destruction across the Southeast and as Hurricane Milton barreled toward Florida. As the impacts of climate change became more real and apparent, the media, as well as local leaders, started looking for a better story to tell.

“People are desperate for optimism,” said Jesse Keenan, director of the Center on Climate Change and Urbanism at Tulane University, who described the concept of climate havens as a fiction. “It gives people hope.”

Keenan actually blames himself for helping to popularize the term. For a concept that feels so widespread now, it’s surprisingly hard to find much mention of climate havens in the media before 2018. That was when the Guardian quoted Keenan in a piece about where you should move to save yourself from climate change that used the phrase “safe havens.” Buffalo, New York, and Duluth, Minnesota, were Keenan’s suggestions.

The concept gained more traction a few months later, when Mayor Byron W. Brown referred to Buffalo as a “climate refuge” in his 2019 state of the city address, followed by outlets like Bloomberg and Quartz referring to Buffalo as a climate haven. The New York Times did a whole spread on “climate-proof Duluth,” a slogan Keenan wrote as part of an economic development package commissioned by the city. He told me it was just a joke that got pulled out of context.

It’s hard to know how responsible one professor with a knack for marketing was for the mainstreaming of the climate haven concept. But it’s easy to see why local governments would latch onto it.

The US Census Bureau estimates that as climate change warms the planet over the next several decades, 100 million people will migrate into and around the US. Increased flood risk may have already pushed several million out of coastal and low-lying areas across the US, as wildfires start to raise questions about migration in the West.

Inland cities, namely those along the Rust Belt that have been losing population for years, see an opportunity to pull those people in. “The idea of a climate refuge itself is kind of an escapist fantasy,” said Billy Fleming, director of the McHarg Center at the University of Pennsylvania. “To the extent that a climate refuge even exists, it’s not a particularly physical or geophysical phenomenon. It’s social and economic.”

Fleming added that, for these would-be climate havens, attracting new residents is a means to pull in more tax revenue and create wealth for the community. “It’s about keeping the real estate machine churning,” he added, “which is the thing that pays for everything else in the city.”

The real estate industry has taken notice. Quite coincidentally, as Hurricane Helene was bearing down on the Southeast last week, Zillow announced a new feature that displays climate risk scores on listing pages alongside interactive maps and insurance requirements. Now, you can look up an address and see, on a scale of one to 10, the risk of flooding, extreme temperatures, and wildfires for that property, based on data provided by the climate risk modeling firm First Street. Redfin, a Zillow competitor, launched its own climate risk index using First Street data earlier this year.

The new climate risk scores on Zillow and Redfin can’t tell you with any certainty whether you’ll be affected by a natural disaster if you move into any given house. But this is a tool that can help guide decisions about how you might want to insure your property and think about its long-term value.

It’s almost fitting that Zillow and Redfin, platforms designed to help people find the perfect home, are doing the work to show that climate risk is not binary. There are no homes completely free of risk for the same reasons that there’s no such thing as a perfect climate haven.

Climate risk is a complicated equation that complicates the already difficult and complex calculus of buying a home. Better access to data about risk can help, and a bit more transparency about the insurance aspect of homeownership is especially useful, as the industry struggles to adapt to our warming world and the disasters that come with it.

“As we start to see insurance costs increase, all that starts to impact that affordability question,” Skylar Olsen, Zillow’s chief economist, told me. “It’ll help the housing market move towards a much healthier place, where buyers and sellers understand these risks and then have options to meet them.”

That said, knowledge of risk isn’t keeping people from moving to disaster-prone parts of the country right now. People move to new parts of the country for countless different reasons, including the area’s natural beauty, job prospects, and affordable housing. Those are a few of the reasons why high-risk counties across the country are growing faster than low-risk counties, even in the face of future climate catastrophes, which are both unpredictable and inevitable. It’s almost unfathomable to know how to prepare ourselves properly for the worst-case scenario.

“The scale of these events that we’re seeing are so beyond what humans have ever seen,” said Vivek Shandas, an urban planning professor at Portland State University. “No matter what we think might be a manageable level of preparedness and infrastructure, we’re still going to see cracks, and we’re still going to see breakages.”

That doesn’t mean we shouldn’t build sea walls or find new ways to fight wildfires. In a sense, we have the opportunity to create our own climate havens by making cities more resilient to the risks they face. We can be optimistic about that future.
