From the top of a plane wing, another airplane is seen flying above clouds in a blue sky, leaving a contrail in its wake. In spring 2023, scientists aboard a research aircraft chased an Airbus A321neo ...

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 ...

The challenge of addressing aviation’s non-carbon dioxide emissions is receiving greater attention, with the climatic impact associated with tell-tale signs in the sky coming under increased study.

Nudging aircraft onto slightly different paths to avoid contrail formation could slash climate warming due to aviation over the next 25 years almost in half, according to a new study. The analysis ...

American Airlines and Google said Thursday that they significantly reduced the climate impact of some of the airline's flights using an AI-based forecasting tool to help prevent contrails. When ...

Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails ...

Aviation’s climate impact extends beyond carbon dioxide emissions. A new study from Chalmers University of Technology and the University of Gothenburg, Sweden, and Imperial College, UK, reveals that ...

PHOENIX (AZFamily) — There have been all kinds of theories about jet contrails over the years. In reality, they have a very simple scientific explanation. You will often see a white streak trailing ...

The contrail clouds formed by jet engines contribute to global warming. In-flight measurements of the particles emitted and contrails produced by a passenger jet show that contrails are formed through ...

MORE ON WHAT CONTRAILS ARE áANDá WHAT THEY ARE NOT. YEAH. LET'S TALK ABOUT CONTRAILS. "NOT CHEMTRAILS." CONTRAILS. WE'LL DISCUSS 'CHEMTRAILS" LATER ON. BUT, YOU'VE SEEN IT BEFORE, I'M SURE. UP WAY UP ...
