Huh, that's strange.
"Space debris is becoming a rapidly growing problem for satellite operators due to the risk of collisions," Ingrid Cnossen, a research fellow at the British Antarctic Survey and the study's author, said in aEveryone's Problem, utilized research models of the entire atmosphere in order to examine how its upper sphere — a region that spans altitudes between 56 and 310 miles from the Earth's surface — has changed over the last 50 years, and what those shifts can likely...
"Changes we saw between the climate in the upper atmosphere over the last 50 years," Cnossen's statement continued, "and our predictions for the next 50 are a result of carbon dioxide emissions." Cnossen's research confirms the belief that, despite their reputation for warming the Earth's surface, greenhouse gases actually have the opposite impact on the atmosphere.
As those CO2 particles suck up the limited available heat up there, the atmosphere shrinks and cools, in an effect that ultimately makes for a smoother, longer orbit for satellites, plus the junk caused by old, defunct spacecrafts. And while satellite makers might be happy to see some crafts comfortably cruise around for longer than expected, everyone
