气候变化可能会增加空间碎片,到2100年将威胁多达66%的安全卫星轨道。 Climate change may increase space debris, threatening up to 66% of safe satellite orbits by 2100.

大自然可持续性新研究警告说,气候变化可能延长空间碎片的存在,从而威胁卫星的安全。 New research in Nature Sustainability warns that climate change could threaten satellite safety by prolonging the presence of space debris. 不断上升的温室气体正在导致上层大气冷却和收缩,减少碎片的拖力,并增加轨道阻塞。 Rising greenhouse gases are causing the upper atmosphere to cool and contract, reducing drag on debris and increasing orbital clutter. 这可能在高排放情景下到2100年时将安全卫星轨道减少66%,可能需要花费昂贵的碎片清除。 This could reduce safe satellite orbits by up to 66% by 2100 under high emissions scenarios, potentially requiring costly debris removal.
