The Surprising Way Airplanes May Be Heating Up the World's Climate

Airplanes and climate changeWhen looking for evidence of humanity's hand in climate change, it's easy to spot the belchers of greenhouse gases sitting at eye level: snaking rivers of bumper-to-bumper cars, say, or vapor-shrouded smokestacks at power plants.

Few people tend to look straight up, though, which if you had done it last Friday would've yielded a jittering mess of billowy streaks.

Contrails are fascinating to look at, especially if you're a UFO conspiracy theorist who is certain that joyriding aliens are responsible. They're also a fascinating player in the warming of the planet, though to what degree is still a matter of debate.

Scientists have known that contrails influence the climate since at least the late 1960s, when two meteorologists named Nicodemus and McQuigg suggested deliberately creating a blanket of contrails over the U.S. Midwest to reduce sun stress on corn crops. In the '80s, others proposed a similar weather modification above cities so people wouldn't have to spend so much on their heating and cooling bills.

A few years ago, a team from NASA’s Langley Research Center dug up evidence that increasing masses of jet-born clouds could help account for a long period of warming in the U.S. from 1975 to 1994. It looked like the jet exhaust had added to the power of the greenhouse-gas effect, the researchers noted, suggesting that future generations will find it necessary to include airplanes in their climate models.
