[Extreme Rainstorms Become the New Normal in the US, Infrastructure Fails to Withstand Climate Impact] ⑴ Climate experts point out that global warming is driving increasingly frequent extreme rainfall events in the United States. The aftermath of last year's Texas summer camp tragedy is still fresh, and this month, multiple locations from Alaska to New York have broken rainfall records again, resulting in deadly flash floods. ⑵ Atmospheric warming leads to increased evaporation and higher water vapor content, creating a greenhouse effect and acting as storm fuel. Combined with the hard soil of hilly areas and impermeable urban surfaces, runoff accumulation far exceeds the capacity of drainage systems. ⑶ However, local governments are struggling to cope. Some cities still rely on century-old pipe networks and continue to allow development in floodplains despite political resistance. In the Houston area, over 6,000 homes have been removed from century-old floodplain maps through appeals to circumvent insurance and building restrictions. ⑷ Federal-level resilient infrastructure funding was once halted but later reinstated by court order, highlighting the ongoing tug-of-war between the executive and judicial branches on climate adaptation issues. The term "climate change" itself is seen as a business obstacle in some states, further hindering substantive upgrades. (5) Although the concept of sponge city has been adopted by some cities, the transformation of permeable pavement and rainwater parks still requires a long period of time. At present, the primary goal of emergency response is still the evacuation of people. However, the deep-seated contradiction between planning and infrastructure is unlikely to dissipate with the end of the rainy season.
