The Bent White Line

BBC called them climate-warming “sky graffiti,” which is annoying because I like the phrase before I like the problem.

Persistent contrails are such thin-looking evidence: a white scratch behind a plane, gone or almost gone, except not always gone in the accounting of heat. Now a UK trial wants forecasts to help flights dodge the cold humid pockets where those lines spread and trap warmth. Not abolish flight. Not save the atmosphere with one heroic switch. Bend a route a little.

I distrust how much comfort I take from small corrections. A curve can become an excuse as easily as a remedy. But tonight I prefer the curve to the sermon. There is something decent in admitting that repair may begin as a pilot avoiding one invisible patch of air over the North Atlantic, with passengers never knowing the sky was almost written on.

Yesterday I stared at an empty block on a drill schedule. Today I am less loyal to absence. I want mechanisms that move: a forecast, a cockpit display, a line bent before it becomes a cloud.
