Overlapping Disasters Expose Harsh Climate Reality: The U.S. Is Not Ready
and In Louisiana and Mississippi, nearly one million people lack electricity and drinking water after a hurricane obliterated power lines. In California, wildfire menaces Lake Tahoe, forcing tens of thousands to flee. In Tennessee, flash floods killed at least 20; hundreds more perished in a heat wave in the Northwest. And in New York City, 7 inches of rain fell in just hours Wednesday, drowning people in their basements. Disasters cascading across the country this summer have exposed a harsh reality: The United States is not ready for the that is now becoming frequent as a result of a warming planet. These events tell us were not prepared, said Alice Hill, who oversaw planning for climate risks on the National Security Council during the Obama administration. We have built our cities, our communities, to a climate that no longer exists. In remarks Thursday, President Biden acknowledged the challenge ahead. And to the country, the past few days of Hurricane Ida and the wildfires in the West and the unprecedented and New Jersey is yet another reminder that these extreme storms and the climate crisis are here, said Mr. Biden, who noted that a $1 trillion infrastructure bill pending in Congress includes some money to gird communities against disasters. We need to do be better prepared. We need to act. The country faces two separate but interlaced problems, according to climate and resilience experts. First, governments have not spent enough time and money to brace for climate shocks that have long been predicted: everything from maintaining and fortifying electrical lines and storm water systems to clearing forests of undergrowth in order to reduce the ferocity of wildfires. Were feeling all the effects of that deferred maintenance, said Kristina Dahl, a senior climate scientist at the Union of Concerned Scientists. But theres a second, more sobering lesson: There are limits to how much the country, and the world, can adapt. And if nations dont do more to cut greenhouse gas emissions that are driving climate change, they may soon run up against the outer edges of resilience. If we already cant cope with where we are, then theres little hope that its going to improve in a warming climate, Dr. Dahl said. The countrys vulnerability in the face of extreme weather was punctuated by the downpour that flooded the countrys largest city. New York City has invested billions of dollars in storm protection since Hurricane Sandy in 2012, investments that seemed to do little to blunt the impact of the deluge. Rain poured down in furious torrents, turning the subway system into a kind of flume ride. Central Park recorded 7.19 inches of rain, nearly double the previous record set in 1927 for the same date, according to the National Weather Service, which issued the citys first-ever flash flood emergency alert. Ahead of the storm, city and state officials activated preparation plans: clearing drains, erecting flood barriers in the subway and other sensitive areas, warning the public. But the rainfall dumped more water, and faster, than what the city factored into its as an . The pattern of damage reflects the relationship between climate exposure and racial inequality: impacts were more apparent in low-income communities of color, which, because of historic inequalities, are more prone to flooding, receive less maintenance from city services, and frequently experience lax housing code enforcement. Most of those killed in New York City drowned when . Many such apartments do not meet safety requirements, but have proliferated as affordable housing for the working poor and undocumented immigrants who may fear complaining to authorities about safety violations. In one case, Tara Ramskriet, 43, and her son Nick, 22, drowned when water filled their basement apartment in the Hollis section of Queens so quickly family members could not pull them out against the flow and a wall collapsed, trapping them inside. Neighbors were outraged, saying it took fatalities to bring city inspectors to the scene. This happens all the time, said Jennifer Mooklal, 33, who lives across the street from the Ramskriets. Even if its just rain, our basement gets flooded. Weve been dealing with this problem for years and have been asking the city but no one is listening to us. Damage from extreme weather, and threats to human life, will only increase as the planet warms. For every 1.8 degrees Fahrenheit of global warming, the atmosphere holds about 7 percent more moisture, scientists . That means much heavier rainfall when storms do occur. Across the continental United States, the heaviest downpours have become more frequent and severe, . The Northeast has seen 50 percent more rainfall during the heaviest storms compared with the first half of the 20th century. New York City is particularly vulnerable to flooding. Three-fourths of the city is covered by impervious surfaces like asphalt, which means runoff is channeled into streets and sewers rather than being absorbed by the ground. And the citys century-old subway system was not designed for a warming climate. Even on dry days, a network of pumps pours out 14 million gallons of water from its tunnels and stations. Heavy rains can overwhelm the system, as they did on Wednesday. The Metropolitan Transportation Authority in resiliency projects since Hurricane Sandy inundated the citys subways in 2012, including fortifying 3,500 subway vents, staircases and elevator shafts against flooding. Still, this weeks flash floods showed that the system remains vulnerable. One reason is that city and federal officials focused on protecting against the kind of coastal storm surge that Sandy wrought, according to Amy Chester, managing director of Rebuild by Design, a nonprofit group that works on climate resilience. But in the case of Hurricane Ida, the main threat was rainwater flowing downhill, not storm surge pushing in from the coast. So much water fell that it overwhelmed storm drains, overflowed riverbanks and poured into basements, from the hilly parts of Manhattans Washington Heights to the inland flats of Jamaica in Queens. The investments that protect against storm surge differ from those that guard against extreme rain, Ms. Chester said. Coping with severe rainfall means more places to absorb and hold water, whether thats so-called green solutions like parks, or traditional structures like underground retention tanks. And it means increasing the capacity of the sewer system to handle a greater volume of water. Because New York has mostly been spared the type of severe rainfall that occurred Wednesday, officials have made it less of a priority. Other countries have heeded the warnings of climate scientists and acted. In the Netherlands, where much of the country lies below sea level, the government strengthened flood design standards and in 2007 created a program called Room for the River, which in essence authorized the wholesale redesign and rebuilding of dozens of vulnerable watersheds around cities like Amsterdam and Rotterdam. The goal was to prepare for the sort of one-in-10,000-year floods that Dutch scientists were warning might become more frequent. In that country, government water boards have the ultimate authority over land use. If they determine an area is needed for flood protection, its residents must move. Specific taxes are dedicated to water management. There is no national flood insurance program for residents in flood zones in the Netherlands because, the Dutch argue, the governments job is to protect people from floods, not help homeowners rebuild in areas vulnerable to damage. Among other things, Room for the River created dozens of new parks, enhancing underserved neighborhoods, resettling populations living in flood zones into new homes out of harms way, and girding the nations economy in the process. Its a different story in the United States, where efforts to adapt and mitigate American cities for severe storms and rising seas have been plodding. There are many reasons: Governments reluctance to impose on private property, a legacy of racial and economic injustice, and a system of governance and regulation that often moves far slower than the hastening pace of climate change. Jainey Bavishi, director of New York Citys Mayors Office of Resiliency, said the city has spent more than $20 billion on resilience since Sandy and that work also includes some protections against extreme rainfall in addition to storm surge. The city is about to break ground on a storm water retention system in Queens. And various other programs have been created to soak up more rainfall: incentives to cover roofs and traffic medians with grass, rain gardens and other more permeable surfaces to slow down and absorb rainwater. The citys Department of Environmental Protection, which handles drainage and sewage, has been quietly working on upgrades for the system, improving and widening the catchment basins under storm grates, designing systems to separate storm water runoff from sewage, and even rushing out before storms to unclog drains. But storm water upgrades for the entire city amount to a massive, multiyear and multibillion-dollar project. It hasnt attracted federal attention and support, particularly under former President Donald J. Trump when climate change preparation was not a priority. So far, officials have upgraded the storm water capacity of just a fraction of the city. The rules that govern federal disaster money have also complicated the citys efforts to deal with extreme rain. Of the $20 billion that New York City has spent on resilience since Sandy, $15 billion came from the federal government, and much of that money had to be linked to Sandy, which meant focusing on storm surge and sea-level rise, Ms. Bavishi said. We know that intense precipitation is a risk, she said. Last nights storm underscored that cities need access to proactive federal funding to get this work done. Even with the right projects designed and funding in hand, climate change is outpacing the speed at which American communities can fortify themselves. Its happening faster than weve anticipated, said Dr. Dahl of the Union of Concerned Scientists, who is 43.
