How global warming could threaten satellites, according to new study
- MIT researchers found that climate change might reduce the available space for satellites in low Earth orbit by one-third to 82% by the century's end, depending on carbon pollution levels.
- The study published in Nature Sustainability explains that cooling in the upper atmosphere will lessen natural debris removal, making space more crowded due to less debris cleanup.
- Scientists emphasize the importance of understanding climate change's effects on orbits for long-term sustainability, as noted by Ingrid Cnossen from the British Antarctic Survey.
- Currently, there are 11,905 satellites orbiting Earth, with 7,356 in low Earth orbit, which are crucial for communications and navigation.

Climate Change Is Shrinking Space for Satellites
Climate change isn’t just affecting Earth, it’s reshaping space as well. A new MIT study reveals that rising greenhouse gas emissions are shrinking the thermosphere, reducing atmospheric drag and allowing space debris to linger longer, increasing the risk of collisions. - Articles from The Weather Channel
Climate Change Might Increase Satellite Collisions, Limiting How Many Can Safely Orbit Earth, Study Finds
Greenhouse gas emissions could reduce drag in the upper atmosphere, leaving more space debris in orbit and making satellites more vulnerable to damage, according to new research
Earth Orbit Is Filling Up with Junk. Greenhouse Gases Worsen the Problem.
Editor’s Note: This story was originally published by Grist. Sign up for Grist’s weekly newsletter here. At any given moment, more than 10,000 satellites are whizzing around the planet at roughly 17,000 miles per hour. This constellation of machinery is the technological backbone of modern life, making GPS, weather forecasts, and live television broadcasts possible. But space is getting crowded. Ever since the Space Age dawned in the late 1950s,…
Now climate change can impact space satellites, study claims · American Wire News
“The sky is quite literally falling,” the author of a recent study and MIT graduate said over alleged changes in the earth’s atmosphere. Human-induced greenhouse gas emissions are causing cooling and contraction in Earth’s thermosphere, leading to a long-term reduction in atmospheric density at altitudes where most satellites operate, according to a study published in Nature Sustainability. This decrease in density lowers drag on debris, extendi…
