Cool Globes: Hot Ideas for a Cooler Planet is a travelling public art exhibit about global warming that for some reason is in Copenhagen right now. The exhibit “will feature over 25 super-sized Cool Globes, each conveying a different message about what ordinary citizens can do to combat global warming. The exhibit will include five-foot diameter, seven-foot-tall globes created by world renowned artists as well as local Danish artists.” Here’s a gallery. Above: “Carpool” by Cheryl Steiger.
