Rocket industry could undo decades of work to save the ozone layer
The ozone layer is on track to heal within four decades, according to a recent UN report, but this progress could be undone by an upsurge in rocket launches expected during the same period.
The ozone layer protects life on Earth from the sun’s harmful ultraviolet (UV) rays.
Destruction of the ozone layer became a major international issue in 1985 when the “ozone hole” was discovered over Antarctica.

Climate damage caused by growing space tourism needs urgent mitigation
The researchers say this is of particular concern, as when the soot particles are directly injected into the upper atmosphere, they have a much greater effect on climate than other soot sources—with the particles 500 times more efficient at retaining heat.
