On the surface, that might be great news for satellite makers, who want functioning crafts to stay in orbit for as long as possible. But there's a catch: this inability to self-clean — a result of excess CO2, which eats away at the density of the upper atmosphere — also means that [polluting](), [dangerous]() space debris stays in orbit for longer, too. "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 a [statement](), "which the long-term decline in upper atmosphere density is making even worse." ## Everyone's Problem The study, published in the journal *Geophysical Research Letters*, 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 foretell about the 50 to come. "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 [ultimately stands to lose]() if space debris gets even more out of hand. New satellites will have a difficult time working in what might pretty much become a [close-orbit junkyard](), and humans, on [the ground]() and [in spac]()e, could face life-threatening consequences. "I hope this work will help to guide appropriate action to control the space pollution problem," added Cnossen, "and ensure that the upper atmosphere remains a usable resource into the future." **READ MORE:** *[Climate change keeps space debris afloat longer]()* \[*Space.com*\] **More on space junk:** *[Russia Forced to Dodge Space Debris From When It Blew Up Satellite]()* ## Author At Futurism, I've reported extensively on the rise of AI as a cultural and business force shaping the media industry, and more broadly how those dynamics are changing how we all consume and share information and relate to one another. I'm also fascinated by public health policy and ethics, the role of emerging tech in politics and governance — and the powerful people and forces at those intersections — climate change, and the environment. My investigation on Sports Illustrated's use of AI-generated authors with fictional biographies won a 2024 Mirror Award for "Best Story on Media Coverage of Artificial Intelligence in Journalism and the Media" from Syracuse University's SI Newhouse School, I contributed to Niemen Lab's 2025 Predictions for Journalism series, and I've discussed my work for Futurism during appearances on NPR, CNN, the BBC, the CBC, and more. I grew up in rural Pennsylvania and attended the University of Massachusetts Amherst, where I played Division I field hockey for the Minutewomen as a midfielder. Since then, I've lived in New Orleans, Louisiana and Manhattan, New York. I spend my free time running, reading, perusing archival fashion, and searching for the world’s best negroni. I also have a debonair tuxedo cat, Westley, who's named after "The Princess Bride." ### Author social links [Bluesky]()
