Climate change may expand airport noise zones by 2050, especially in Europe, due to warmer air slowing aircraft climbs.
A new study predicts climate change will significantly increase airport noise by 2050, especially in Europe, as warmer air reduces aircraft lift and slows climb rates, prolonging noise exposure.
Researchers found takeoff climb angles could drop by up to 3% on average and as much as 7.5% on hot days, expanding the area affected by aircraft noise—particularly at the 50-decibel threshold.
In central London, about 60,000 people currently live within this noise zone, with roughly 2,500 more expected to be added due to climate and population shifts.
Low-frequency noise, which travels farther and is more disruptive, is projected to rise the most, increasing risks of stress and sleep issues.
Scientists warn that even with improved engine technology, rising temperatures will make noise management harder unless greenhouse gas emissions are reduced.
El cambio climático puede expandir las zonas de ruido de los aeropuertos en 2050, especialmente en Europa, debido a que el aire más cálido ralentiza las subidas de los aviones.
