Business and political leaders are descending on Davos, Switzerland, for the annual World Economic Forum, which kicks off tomorrow. The forum will offer various climate-related sessions, including one led by Intergovernmental Panel on Climate Change Chair Rajendra Pachauri; one which will be a discussion between Al Gore and Bono; and one with the ominous title Beyond Kyoto: Is Collaboration Possible? Luminaries’ travel to and participation in the five-day meeting is expected to produce some 7,500 tons of greenhouse gases, 70 percent of which the forum hopes to make up for by sending solar cookers to impoverished folks in China.
