Although you cannot feel it, Earth's atmosphere presses down with the force of one kilogram per square centimeter, or 14.7 pounds per square inch. That pressure works out to about a ton per square ...

Carbon Dioxide Emissions Predicted To Reduce Density Of Earth's Outermost Atmosphere By 2017. ScienceDaily . Retrieved June 4, 2025 from www.sciencedaily.com / releases / 2006 / 12 / 061211221048.htm ...

“The long-term decline in upper atmosphere density is making [the issue] even worse,” she added. NASA tracks the approximate number of objects in orbit around Earth.

However, a recent study published Sept. 23 in Geophysical Research Letters shows that increased levels of carbon dioxide will reduce the density of Earth’s upper atmosphere.

ERS-2, a satellite commissioned by the European Space Agency nearly 30 years ago, is set to reenter the Earth’s atmosphere this morning—though the ESA said this poses an extremely low risk to ...

The finding suggests that the thermosphere, the part of the atmosphere rising from 90 to 1000 kilometres above Earth, is cooling and decreasing in density by two to five per cent per decade.

Based on the planet's density, astronomers estimate that GJ 1214b would be about three-quarters water with a solid core and an atmosphere—not unlike Earth. But it seems the similarities stop there.

Lower density inthe thermosphere, which is the highest layer of the atmosphere, would reduce the drag on satellites in low Earth orbit, allowing them to stay airborne longer.
