A team led by Massachusetts Institute of Technology researchers determined that, with Earth's warming, space debris could accumulate enough to reduce the low Earth orbit area available for satellites by between a third and 82% by the year 2100, as the Associated Press detailed. The reason for this, per the study published in Nature Sustainability in March, is that climatic changes high above ground could reduce the effectiveness...
