=== (AGENDAWATCHDOG) === Earth’s stratosphere is shrinking due to greenhouse gas emissions, and it could have a devastating effect on satellite operations and GPS, experts have warned.
A study by Charles University in Prague found the region of the atmosphere from 12 to 40 miles above the Earth has been shrinking by 328ft per decade.
The team predict that over the next 60 years, under current climate change predictions, the upper part of the stratosphere could shrink by four per cent.
This would take another 3,200ft from the top of the stratosphere – enough to put some satellites at risk due to less air friction for them to operate in.
Since the 1980s, when they began observing the extent of the stratosphere, it has shrunk by about 1,300ft, but it was likely shrinking before this, they said.
This is because, before the 1980s, when Earth observing and high orbiting satellites were launched, there was not enough data from so high in the atmosphere.
According to the team behind the new discovery, if the disruption continues then it could impact satellite trajectories and their measurements.
