COLBERT: "The temperature is so high in Phoenix, Arizona, that flights are being cancelled because it's too hot for planes, because at higher temperatures, the air has a lower density, which reduces how much lift is generated.

Forget rising sea levels and droughts, this could be the disaster that finally convinces skeptics that climate change is real: A layover in Phoenix."
