New York’s multi-billion plan to thwart climate change impacts

Architecture is now beginning to consider the ecological ramifications of new builds, but resiliency projects will be needed to protect cities from the more immediate impacts of climate change. On that front, plans for New York City are already well underway.

Constantly the backdrop for fictional menaces and mass destruction, whether that be at the hands of a giant marshmallow man, a rampaging gorilla, the Cloverfield monster, a tornado of sharks, or the entire cast of the Avengers, New York City is now preparing for a very real adversary: climate change.

Renowned as the economic hub of the US – as well as one of the nation’s most populous cities – New York is pre-empting worsening extreme weather events that will arrive should we fail to meet global decarbonisation targets.

During COP26, climate experts at Sky News put together illustrations of what 3C warming would do to major conurbations throughout the States, and it appears city planners in the Big Apple have gotten the message.

As it’s surrounded by some 830km of coastline, the most pertinent concern is obviously rising sea levels – which climate experts fear could consolidate between 20 and 75cm by 2050. Anywhere in this predicted range would quite literally leave areas of East Manhattan underwater.

To prevent both the worst eventualities and minor inconveniences in the foreseeable future, the East Side Coastal Resiliency Project will create protective infrastructure stretching 4km across the city border.

Mobilised by climate experts within the Mayor’s Office, $1.4bn will now see raised parklands built, as well as floodwalls, berms, and movable floodgates to create a stern line of defence against coastal storms and rising sea levels.

‘This project will keep New Yorkers safe from coastal storms and rising seas for decades to come, while also investing in amenities and improving access to public spaces on the East Side of Manhattan,’ says project spokesperson Jainey Bavishi.

A more generous budget of $20bn has been allocated to keep the city safe from climate disasters should it be required, and sewer systems are being modernised to deal with a far larger volumes of water. If the coaster barriers fail, civilians with buckets likely won’t cut it.

Though these developments aren’t yet commonplace across the wealthy west, they will inevitably sprout if our decarbonisation targets aren’t met. New York has become one of the first major cities to jump following the havoc caused by summer storms Ida and Henri, resulting in billions worth of damages and over 50 deaths.

Given our dire climate situation now, the planet’s most vital natural ecosystems are receiving the most attention. Regeneration will rightfully take precedence until the turn of the decade, but urban mechanisation will also need to grow as a last line of defence for cities.

In works of fiction New York is unrivalled in its canny ability to rebuild itself, but the reality will be starkly different if COP delegates fail to make good on their climate pledges.
