Air travel has come under fire for its potential contributions to climate change. Most people probably assume that its impact comes through carbon emissions, given that aircraft burn significant amounts of fossil fuel to stay aloft. But the carbon released by air travel remains a relatively minor part of the…

Over time, these thin lines of water evolve into “contrail cirrus” clouds that lose their linear features and become indistinguishable from the real thing.
Although low-altitude clouds tend to cool the planet by reflecting sunlight, high-altitude clouds like cirrus have an insulating effect and actually enhance warming.
To figure out the impact of these cirrus clouds, the authors created a module for an existing…
