"Climate-savvy travelers are likely aware of the global impact of flying. The aviation industry is working hard to decarbonize, but carbon dioxide emissions are only half the story. Contrails—clouds of condensed water that trail behind a jet—may be just as important as carbon dioxide when it comes to global warming. This makes eliminating contrails an attractive target for climate action. New research led by scientists at the German Aerospace Center suggests that it won’t be easy: Removing soot emissions doesn’t prevent contrail formation (Nature 2026, DOI: 10.1038/s41586-026-10286-0)."
