研究人员提议利用货机在电线杆上方喷洒颗粒以冷却地球, 但警告这不是减排的替代品。 Researchers propose using cargo planes to spray particles above poles to cool Earth, but warn it's not a replacement for emissions cuts.

一项新的UCL研究表明,现有的货机,如波音777F号飞机,可以通过在极地区域上空喷洒颗粒来冷却地球,这一过程称为平流层喷雾。 A new UCL study suggests that existing cargo planes, like the Boeing 777F, could be used to cool the Earth by spraying particles above the polar regions, a process called stratospheric aerosol injection. 该技术涉及释放二氧化硫粒子以反映阳光,每年可能使地球冷却0.6°C。 The technique involves releasing sulfur dioxide particles to reflect sunlight, potentially cooling the planet by 0.6°C annually. 然而,该方法可能造成酸雨等问题,研究报告强调,该方法不能取代减少温室气体排放。 However, the method could cause issues like acid rain, and the study emphasizes that it is not a replacement for reducing greenhouse gas emissions.
