Americans: the next climate migrants

By Oliver Milman, The Guardian, 24 Sep 2018

After her house flooded for the third year in a row, Elizabeth Boineau was ready to flee. She packed her possessions into dozens of boxes, tried not to think of the mold and mildew-covered furniture and retreated to a second-floor condo that should be beyond the reach of pounding rains and swelling seas.

Boineau is leaving behind a handsome, early 20th-century house in Charleston, South Carolina, the shutters painted in the city’s eponymous shade of deep green. Last year, after Hurricane Irma introduced 8in of water into a home Boineau was still patching up from the last flood, local authorities agreed this historic slice of Charleston could be torn down.

“I was sloshing through the water with my puppy dog, debris was everywhere,” she said. “I feel completely sunken. It would cost me around $500,000 to raise the house, demolish the first floor. I’m going to rent a place instead, on higher ground.”

Millions of Americans will confront similarly hard choices as climate change conjures up brutal storms, flooding rains, receding coastlines and punishing heat. Many are already opting to shift to less perilous areas of the same city, or to havens in other states. Whole towns from Alaska to Louisiana are looking to relocate, in their entirety, to safer ground.

The era of climate migration is, virtually unheralded, already upon America.

The population shift gathering pace is so sprawling that it may rival anything in US history. “Including all climate impacts it isn’t too far-fetched to imagine something twice as large as the Dustbowl,” said Jesse Keenan, a climate adaptation expert at Harvard University, referencing the 1930s upheaval in which 2.5 million people moved from the dusty, drought-ridden plains to California.

This enormous migration will probably take place over a longer period than the Dustbowl but its implications are both profound and opaque. It will plunge the US into an utterly alien reality. “It is very difficult to model human behaviour under such extreme and historically unprecedented circumstances,” Keenan admits.

The closest analogue could be the Great Migration--a period spanning a large chunk of the 20th century when about 6 million black people departed the Jim Crow south for cities in the north, midwest and west.

By the end of this century, sea level rise alone could displace 13 million people, according to one study, including 6 million in Florida. States including Louisiana, California, New York and New Jersey will also have to grapple with hordes of residents seeking dry ground.

“There’s not a state unaffected by this,” said demographer Mat Hauer, lead author of the research, which is predicated on a severe 6ft sea level increase. There are established migration preferences for some places--south Florida to Georgia, New York to Colorado--but in many cases people would uproot to the closest inland city, if they have the means.

“The Great Migration was out of the south into the industrialized north, whereas this is from every coastal place in the US to every other place in the US,” said Hauer. “Not everyone can afford to move, so we could end up with trapped populations that would be in a downward spiral. I have a hard time imagining what that future would be like.”

Within just a few decades, hundreds of thousands of homes on US coasts will be chronically flooded. By the end of the century, 6ft of sea level rise would redraw the coastline with familiar parts--such as southern Florida, chunks of North Carolina and Virginia, much of Boston, all but a sliver of New Orleans--missing. Warming temperatures will fuel monstrous hurricanes--like the devastating triumvirate of Irma, Maria and Harvey in 2017, followed by Florence this year--that will scatter survivors in jarring, uncertain ways.

The projections are starting to materialize in parts of the US, forming the contours of the climate migration to come.

“I don’t see the slightest evidence that anyone is seriously thinking about what to do with the future climate refugee stream,” said Orrin Pilkey, professor emeritus of coastal geology at Duke University. “It boggles the mind to see crowds of climate refugees arriving in town and looking for work and food.”

Pilkey’s new book--Sea Level Rise Along Americas Shores: The Slow Tsunami--envisions apocalyptic scenes where millions of people, largely from south Florida, will become “a stream of refugees moving to higher ground”.

“They will not be the bedraggled families carrying their few possessions on their backs as we have seen in countless photos of people fleeing wars and ethnic cleansing, most recently in Myanmar and Syria,” Pilkey states in his book. “Instead, they will be well-off Americans driving to a new life in their cars, with moving trucks behind, carrying a lifetime of memories and possessions.”

Dejected with frigid New York winters, Chase Twichell and her husband purchased a four-bedroom apartment in Miami Beach in 2011, with the plan of spending at least a decade basking in the sunshine. At first, keeping a pair of flip-flops on hand to deal with the flooded streets seemed an acceptable quirk, until the magnitude of the encroaching seas became apparent when the city spent $400m to elevate streets near Twichell’s abode.

Twichell began to notice water pumps were spewing plastic bags, condoms and chip packets into the bay. Friends’ balconies started getting submerged. Twichell, a poet, found apocalyptic themes creeping into her work. Last year, she sold the apartment to a French businessman and moved back to upstate New York.

“It was like end of the world stuff,” she said. “It was crazy for us to have such a big investment in such a dangerous situation.” Her neighbours initially scolded her but now several are also selling up, fretting that the real estate and insurance markets for properties like theirs will seize up.

“It was horrible but fascinating to see it,” Twichell said. “It’s like we got to see the future and it wasn’t pretty. It’s like a movie where there’s a terrible volcano that is destroying everything, only it’s much slower than that.”

A sense of fatalism is also starting to grip some local officials. Philip Stoddard, mayor of South Miami, has seen a colleague, spooked by sea level rise, move to California and some neighbours sell their houses before an expected slump in prices. Stoddard and his wife regularly discuss buying a fallback property, perhaps in Washington DC.

“Most people will wait for the problem to be bad to take action, that’s what I worry about,” he said. “We can buy a lot of time, but in the end we lose. The sea level will go over the tops of our buildings.”

Those living near the coasts will face pressures of the gradual (sea level rise) as well as dramatic (storms) nature but people inland will also be harried to move by climate change.

Farming techniques and technology have improved immeasurably since the Dustbowl but rising temperatures are still expected to diminish yields for crops such as maize, soybeans and wheat, prompting the departure of younger people from farming. By 2050, Texas county, the largest wheat-producing county in Oklahoma, could spend an extra 40 days a year above 90F (32C) compared with now.

A study published last year found that the economies of the southern states, along with parts of the west, will suffer disproportionately as temperatures rise. Wealth, and potentially people, are expected to shift north and west.

Meanwhile, cities already struggling with heat will see wealthy residents head for cooler climes. Last year, 155 people died in Phoenix due to a particularly fierce summer. Increasing heat will start testing the durability of the populace, even those shielded by air conditioning. In the western states, wildfires are getting larger, razing homes in ever more spectacular ways and choking thousands of people with carcinogenic smoke.

Further to the south, at the border, there are suggestions that people from Central America are being nudged towards the US because of drought and hurricanes in their homelands, part of a trend that will see as many as 300 million climate refugees worldwide by 2050.

“People will get very grumpy and upset with very hot temperatures,” said Amir Jina, an environmental economist at the University of Chicago who co-authored the research on economic losses. “Even if you have air conditioning, some areas start to look less habitable. By the middle of the century parts of the south-west and south-east won’t look attractive to live in.

“That insidious climate migration is the one we should worry about. The big disasters such as hurricanes will be obvious. It’s the pressures we don’t know or understand that will reshape population in the 21st century.”

Some will just grimly hang on. “With property rights as strong as they are in the US, some people may choose to go down with the ship,” said Harvard’s Keenan. “The question is whether they have the means and the options to do anything else.”

“People can usually cope with being a little less comfortable, but if you see repeated storms or severe damage to crops, that will trigger change,” said Solomon Hsiang, who researches how climate change will affect society at the University of California.

“There will be pressure to move a little north. It won’t be everyone, though, it won’t be like the great migration of wildebeest in Africa. Whole cities picking up and moving would be hugely expensive.”

Ultimately, the US will have to choose what it wants to defend and hope its ingenuity outstrips the environmental changes ranged against it. Not everyone will be able to shelter behind fortifications like the ‘big U’ planned to defend lower Manhattan. Wrenching decisions will have to be made as to what and where will be sacrificed.

“We won’t see whole areas abandoned but neighborhoods will get sparse and wild looking, the tax base will start to crumble,” said Stoddard, mayor of South Miami. “We don’t have the laws to deal with that sort of piecemeal retreat. It’s magical thinking to think someone else will buy out your property.

“We need a plan as to what will be defended because at the moment the approach is that some kid in a garage will come with a solution. There isn’t going to be a mop and bucket big enough for this problem.”
