New research shows that planes are contributing to global warming through the white, vapour trails they leave in the sky, research has found.
These trails are thin clouds of ice particles and soot and are threatening the environment as they act as ‘blankets’ trapping heat below them.
The white streaks do more damage to the climate than the carbon dioxide emitted by the aircrafts, experts suggest.
They warned the impact of the vapour trails will only get worse as air traffic is expected to quadruple by 2050.
The white streaks, also known as contrails, form high in the atmosphere when the water vapour in the plane’s exhaust condenses and freezes in the air.
