A river flows in Brooklyn
A river flowed from Prospect Park through my neighborhood in South Slope, Brooklyn on Friday when we were pummeled with 7+ inches of rain in ~12 hours. I didn’t realize NYC’s floods were international news until I started getting messages from friends outside the country. With over 13 inches of rain in September, this is the 2nd wettest September since NYC began keeping weather records in 1920.
I took this photo of the flooding from my apartment at 8am. As I watched the water gushing through the streets, I thought about a conversation I had with my friend, Alex MacLennan, almost a decade ago. He told me the climate models then predicted the western half of the US would grow increasingly drier and hotter while the eastern half would be regularly flooded. How right they were.
NYC is an archipelago that sits mostly at sea-level surrounded by brackish water with the busiest shipping port in the US. Though it looms large on the national and international stages as a financial, cultural, political, and media capital, area-wise it’s small and easily overwhelmed by water.
It is, in many ways, a climate disaster waiting to happen. It’s the mostly densely populated city in the U.S. with nearly 28,000 people per square mile and has the largest population with almost 9 million people, more than double the size of the next largest city. The population doubles during the workday with as many commuters as residents. It’s also a city of hard surfaces (though we have 7 million trees and the tree canopy covers 21% of the city). Aged infrastructure and a subterranean subway that is 100+ years old further compound threats from flash flooding, coastal storms, and sea level rise. Flooding here is a crisis that must be urgently and unrelentingly addressed.
The country and world can’t afford to lose New York. While some strides have been made to protect the city from climate change, it’s not nearly enough. But all that may be changing, and fast.
There are plans underway to transform Governor’s Island in New York Harbor into the largest climate research and entrepreneurial center in the world. We desperately need this. The scale and impact of this project on our city, the country, and the world will be significant. It has to be significant because the climate crisis deepens every day.
These floods will become more frequent and intense in the coming years. We have to mitigate and adapt at the same time with nature-based solutions like biophilic architecture, mangroves, reefs, rooftop farms, and the transformation of vacant lots into bioswales. They are proven, efficient, and relatively inexpensive solutions. I hope the work at Governor’s Island can make these ideas realities.
Like all investments, nature-based solutions take time to create and scale. We have no more time to waste. We have to get started now, and it’s my hope that I can do my part to push this work forward.
