A crazy cold week in Florida brings starker contrails. But it's just winter conspiring against us, not the feds trying to ...

Some contrails can contribute to global warming. Contrails—pure ice clouds (“cirrus”) that form from aircraft exhaust under specific cold conditions—can trap heat in the atmosphere, sometimes creating ...

Contrails are clouds made of ice particles, which can be created when airplanes fly through cold, humid air. Persistent contrails are estimated to have a warming climate impact. Flight tests will ...

Contrails in the blue sky remind us of daily air traffic—and its impact on the climate. However, the effect of contrails on the climate is still only partially understood. It is assumed that they have ...

Aviation's climate impact is partly due to contrails—condensation that a plane streaks across the sky when it flies through icy and humid layers of the atmosphere. Contrails trap heat that radiates ...

Four research figures show how contrails appear in two satellite views (left) and two photographs taken from the MIT Green Building. Aviation’s climate impact is partly due to contrails — condensation ...
