Infrastructures not built to handle warmer, wetter climates are increasingly dangerous. Jose, California, last year. Water in the basement apartments rose and seeped from the rooftops. Rain flowed on metro stations and gathered on the rails. The remnants of Hurricane Ida, which shook the Persian Gulf coast earlier this week, caused flooding in the northeast. Across the region, the death toll had risen to 40 by Thursday evening. Continuing delays in the metro and suspension.
You see, the city's infrastructure was built in the late 19th and early 20th centuries to withstand the storms that come every 5 to 10 years. Record-breaking wild storms are now an annual occurrence. What remains of Aida turns the daily commute into a troubling reminder that climate change is happening to all of us. Severe clouds of fire in the west, blackouts in Texas, storms in the south, torrential rains in the east: “Everything we said would happen 20 years ago,” says Zeke Hausfather, a climate scientist and director of climate and energy at the Success Institute. Everything at once."
Road storms have filled up. But it has also overshadowed the alternatives to targeting people from its cars: bike lanes, sidewalks, and public transit systems. For a while in New York on Thursday, everything was underwater. Pictures of water leaks in metro stations brought the crisis home. “You don't have to be someone with an understanding of infrastructure to know that this is a problem,” said Michael Horodinisano, former president of Metropolitan Capital Construction and current director of the Institute for Building Innovation. NYU "We're seeing results that, in my opinion, pay very little attention to what our infrastructure is doing."Advertising
New York experienced its first weather-related awakening nine years ago, when Hurricane Sandy swept through low-lying areas and, yes, subway stations. Since then, the city has spent about $20 million on climate change adaptation, according to the Mayor's Office of Resilience. But part of the budget was spent on solving a different problem than Ida presented: water from rivers. This week, all the wet material fell from the sky and even the threatened areas above sea level.
Aida's remains dumped all that water in the Northeast due to climate change. You might expect less rain on a warming planet, but some parts of the world, including the Northeast and Midwest of the United States, are seeing more rain. "Temperature directly affects the amount of moisture in the atmosphere before it starts to rain," Hasbro says. Cool air retains less moisture - and warmer air stores more moisture after rain. As a result, winds of 150 miles per hour are generated. As a swirling mass of hot air, Aida retained plenty of moisture. Thus, although the winds decrease with pressure on the ground, the storm carries a large amount of moisture to the north and swallows some along the way.
Climate change did not cause Hurricane Ida, but scientists know how climate change is caused by hurricanes like Ida. "This is one of the simplest physical relationships we have in climate: you heat the atmosphere for every degree Celsius, and you get about 7% moisture in the air, and that means you can get a lot of rain." ' ' , says Hauspar. Storms have become wetter over the past few decades and are expected to continue into the future. "Scientists have also shown that storms, such as Ida, have been accelerating faster in recent years due to global warming. More than 100 years ago, when engineers dreamed of a sewage system, they thought it was the worst." The system that could destroy it is a storm that may only occur once in the next ten or twenty years. But Hell certainly wasn't one in five. The standard will be like a century. p> He has studied New York, and says heavy rain is often due to the movement of small cells over the city. "So it's probably raining everywhere, but it's really heavy in a smaller area." Until the next morning, downtown was muddy and full of potholes.
Now after years of modernization, 60% of New York City is infected with M bags is a mixed wastewater system, which uses a single pipe to carry sewage and rainwater to treatment plants. During severe rainstorms, the system is rapidly compressed. The ruins of urban life - trash, plants, guns - are banned, further poisoning things. "If I get a high priest like that, I don't think he can really evacuate fast enough to prevent a flood." Drain systems are clogged, especially when a storm threatens. They are made to allow fresh air to flow into the underground spaces, but now they look like holes to let in more water. In some places, the MTA has built floodgates, which can be closed if water gets too close.
In general, cities like New York can build more green infrastructure to help solve water problems—essentially, less sidewalks and more soil. For example, you could create green spaces along the road where water seeps into storm drains before it is moved and removes debris and pollution. Los Angeles did this to get rain water. "It's been a long time," Horodinisano says. Retooling cities to deal with what is in the future, and what is in the present, will destroy one of the rarest resources: a much larger budget.
