Right now, every moment of every day, we humans are reconfiguring Earth’s climate bit by bit. Hotter summers and wetter storms. Higher seas and fiercer wildfires. The steady, upward turn of the dial on a host of threats to our homes, our societies and the environment around us.

We might also be changing the climate in an even bigger way.

For the past two decades, scientists have been raising alarms about great systems in the natural world that warming, caused by carbon emissions, might be pushing toward collapse. These systems are so vast that they can stay somewhat in balance even as temperatures rise. But only to a point.

When Hurricane Sandy rammed the Jersey Shore on the night of Oct. 29, 2012, saltwater fisherman Nick Honachefsky was living in Camp Osborn, a community of tiny bungalows a mile south of Mantoloking on Barnegat Bay Island. Earlier that day, Honachefsky had taken a bottle of Captain Morgan rum with him on a walk down the beach, figuring the arrival of a hurricane meant it was time to start drinking and take a few pictures. The news that cops were banging on doors, telling people who were insisting on riding out the storm that they should write their Social Security numbers on their wrists so their bodies could be identified later — plus a phone call from his worried mom — made Honachefsky decide to spend the night at an ex-girlfriend’s house on the mainland.

A few hours later, the storm’s surge roared on top of a high tide across the skinny barrier island, opening broad new inlets as the Atlantic poured up Barnegat Bay. Most of the bungalows that made up Camp Osborn, including Honachefsky’s 750-square-foot house, were washed away. A friend of Honachefsky filmed the storm’s arrival. “He’s like, ‘I think I did see your house. It was the blue one, right? Yeah, it’s floating down Route 35. It’s on fire,’” Honachefksy remembers. When he was finally able to return to the site of Camp Osborn 10 days later, Honachefsky saw 30-foot flames of gas still shooting out of the ground. “It looked like the oil fields in Kuwait,” he says. An exploding transformer had kicked off a fire that continued to burn; there was no gas shutoff valve for the island.

As the past few weeks have shown, flash floods can develop very quickly in both rural and urban areas, with mild to catastrophic impacts. That’s part of why flash floods are so critical to study, according to Andrew Kruczkiewicz, a meteorologist and senior staff researcher at the Columbia Climate School’s National Center for Disaster Preparedness. “Some parts of the world will never see potential disasters like wildfires or tropical cyclones, but there are very few areas at zero risk of flash floods,” says Kruczkiewicz. And because of the wide variability in potential impact, “it demands extra sensitivity in terms of how you communicate risk, as a run-of-the mill flash flood is very different than a 30-foot wall of water.”

Kruczkiewicz’s current research focuses on extreme weather events such as flash floods, and the application of climate and weather data and forecasting to reduce disaster risk and facilitate humanitarian action. In the following discussion, Kruczkiewicz talks about why the Texas floods were so devastating, how warning systems need to consider very different populations—e.g., recreation-seekers vs. locals—and how we might integrate both technology and local knowledge to avoid such tragedy in the future.

Nearly every county in the United States has experienced flooding in the past few decades, but just 4% of homeowners nationwide have flood insurance, according to the Federal Emergency Management Agency.

It’s what experts call the flood insurance gap. Most homeowners insurance doesn’t cover flooding. And while FEMA aid may be available to help people repair their homes after federally declared disasters, it often covers just a fraction of the costs.

That means when floodwaters come, people frequently are on their own to pick up the pieces. It’s a reality communities across the country are facing after flooding hit parts of Texas, New Mexico and North Carolina in the past week alone. In all three states, the floods were caused by extremely heavy rainfall inland — a risk that’s growing with climate change. A warmer atmosphere can hold more moisture. As temperatures rise, it’s fueling more intense rainstorms that drop more water in shorter periods of time.

The unprecedented rainfall that remnants of Hurricane Ida dumped Wednesday night made New York City’s climate vulnerabilities starkly visible, less than two weeks after Tropical Storm Henri broke previous rain records.

Boulevards across boroughs could’ve been mistaken for rivers. Yankee Stadium became a lake. Waterfalls cascaded into subway stations. 

The scenes were vastly different from those from the coastal flooding in 2012’s Superstorm Sandy, which prompted high-profile protection projects focused on waterfront areas vulnerable to storm surge and sea-level rise.

The recent deluges highlight how heavy rains have been largely left out of the equation, experts told THE CITY.

Interviews with over a half dozen experts and Staten Island residents reveal how air pollution served as a dangerous antecedent to a coronavirus outbreak that ravaged the borough and underscores the need to improve ozone smog on the Island.

…And while the North Shore — above the Staten Island Expressway — has over half the population of the rest of the borough, it has only around 30% the number of trees compared to the Island below the expressway, giving it less green space that can improve air quality, according to NYC Parks Department data.

That total could be further diminished by the creation of a BJ’s Wholesale Club that would result in the destruction of 18 acres of woodland next to the wetlands in Mariners Harbor.
