Since the 1980s, the Earth's stratosphere has become thinner by 400 meters. If carbon dioxide emissions are not reduced, it will lose another kilometer in thickness by 2080. According to The Guardian, changes in the structure of the atmosphere can affect the operation of satellites, GPS, and radio communications.
Under the stratosphere, there is the troposphere, where we all live. The CO₂ emissions in this layer heat and expand the air, causing the lower boundary of the stratosphere to move upward. There, carbon dioxide cools the air and makes it shrink.
Scientists have already known that the troposphere is expanding as CO₂ emissions rise, so they have already hypothesized that the stratosphere is thinning. New research had proven that this is actually happening. At least since the 1980s, when the first satellite data appeared.
Prior to this scientific work, researchers believed that the stratosphere was shrinking due to ozone loss. The fewer ozone there is, the weaker this layer of the atmosphere heats up. But new data have shown that CO₂ is to blame for the thinning.
