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 from the planet’s surface, and while the magnitude of this impact is uncertain, several studies suggest contrailsContinue Reading
