You have to recognize the irony of protesting global warming in a snowstorm with temperatures in the teens, but that's what about 50 Minnesotans did today as part of the world-wide effort to fight global warming. Persons from 30 nations are expected to participate. According to the Vancouver Sun , thousands of people also braved freezing temperatures in Montreal to join in the protest which is scheduled to coincide with a "10-day UN Climate Change Conference underway in Montreal, where officials are reviewing and updating the Kyoto Protocol on lowering greenhouse gas emissions."
