The times they are a-changin’: The outgoing leader of Greenpeace has admitted his organization’s recent claim that the Arctic Ice will disappear by 2030 was “a mistake.”  Greenpeace made the claim in a July 15 press release entitled “Urgent Action Needed As Arctic Ice Melts,” which said there will be an ice-free Arctic by 2030 because of global warming. Under close questioning by BBC reporter Stephen Sackur on the “Hardtalk” program, Gerd Leipold, the retiring leader of Greenpeace, said the claim was wrong. “I don’t think it will be melting by 2030. … That may have been a mistake,” he said. Sackur said the claim was inaccurate on two fronts, pointing out that the Arctic ice is a mass of 1.6 million square kilometers with a thickness of 3 km in the middle, and that it had survived much warmer periods in history than the present. The BBC reporter accused Leipold and and Greenpeace of releasing “misleading information” and using “exaggeration and alarmism.”
