Critics are saying that The Washington Post published a misleading photo of a coal plant appearing to spew pollutants to accompany an op-ed about global warming by a liberal columnist.

Post columnist Eugene Robinson argued that President Obama should devote the remainder of his time in office to global warming, using executive power when necessary. In the print edition, Robinson’s article is accompanied by a photo of a coal-fired power plant against the setting sun, spewing out what looks like smoke and other pollutants.

The caption of the AP photo reads: “Silhouetted against the sky at dusk, excess steam, along with non-scrubbed pollutants, spew from the smokestacks at Westar Energy’s Jeffrey Energy Center coal-fired power plant near St. Marys, Kansas.”
