Western University expands use of meteor cameras to track contrails and tackle aviation-induced climate change ...

Condensation trails left by higher-flying, lower-carbon aircraft are proving to be disruptive across North America.

Some aircraft contrails are considered to be particularly harmful to the climate. While the EU is already considering financial charges for polluters, the airlines are pushing for more research.

Contrail • Contrails or vapor trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure, typically at aircraft cruising altitudes several kilometres/miles ...

Still, claims of weather-control technology, once confined to relatively fringe circles, have gained some traction in the Republican Party. In some states, conservative politicians have passed laws ...

Aircraft condensation trails criss-crossing the sky may be warming the planet on a normal day more than the carbon dioxide emitted by all planes since the Wright Brothers' first flight in 1903, a ...

Yet all the evidence we have seen to date has been very weak. The most common claim is simply that aircraft contrails look ‘different’, without any comparative analysis.

A persistent non-spreading contrail will stay in the sky long after the airplane has flown out of sight. It can last for a few minutes or longer than a day, and it keeps the shape of a thin line.
