Hurricanes Moving Farther North to Pummel Millions More Homes in US

Hurricanes are generally poised to strike New York and neighboring states more often as storms track northward, according to the latest projections from the First Street Foundation. The non-profit estimates annual damages from high winds will increase by $1.5 billion to nearly $20 billion in 2053, with the large majority of damages remaining concentrated in Florida.

But the Mid-Atlantic will see the largest increase in maximum wind speeds — with some gusts 37 mph — while the Northeast is expected to see the highest spike in damages (87%). The top five counties by % increase in annual losses include both region: Brooklyn (Kings, NY); Nassau, NY; Monmouth, NJ; Newport News, VA; and York, VA.

That’s the bad news; the good news is that each of these counties has the resources to adapt. According to Climate Alpha’s scenario forecaster, four of the five counties are projected to shave less than 1% from their appreciation forecasts under even the worst scenario (RCP8.5) through 2040. (The exception is Brooklyn, with a 7.5% shortfall in appreciation.)

The takeaway? It’s critical to weight climate risks in context. Visit www.climatealpha.ai to sign up for a free account to see which way — and how hard — tomorrow’s wind is blowing.

Population Growth Is Making Hurricanes More Expensive

Why has the number of hurricanes causing $1 billion or more in damage more than doubled since the 1980s? And why has the total cost in damages risen eleven times?! The New York Times’ Ian Prasad Philbrick and Ashley Wu explore the “expanding bull’s-eye effect” — the tendency of population growth to make climate disasters costlier over time.

Coined by Villanova’s Steven Stader, the expanding bull’s-eye effect not only describes how urban sprawl makes regions more vulnerable to a mega-storm like #HurricaneIan, but also how development lessens the natural resilience of coastlines by transforming wetlands into impermeable asphalt.

The authors offer three potential solutions: mitigating greenhouse gas emissions; strengthening building codes; and encouraging migration away from high-risk areas. “But relocation is a tough sell,” they write. “Americans have flocked to Florida’s picturesque coast, despite its risks.”

They may not have that far to move. In our analysis of post-Ian Florida real estate trends, the Zip codes and counties poised to grow fastest in the next two decades are those farther from the coast. Read our analysis of how and why the smart money will escape the bull’s-eye.
