Captain Climate, outfitted in a red cape and leotard, and his sidekick Boy Atmosphere have been trailing the presidential candidates around New Hampshire, trying to get them to explain what they plan to do about global warming. The Captain tells reporters he has time-traveled back from 2050 and a world nearly destroyed by climate change, with the aim of helping us avert disaster. (Actually, he’s just a recent Dartmouth grad, but you didn’t hear it from us.) In other campaign news, eight environmental and human rights activists were arrested this week for staging a sit-in at the New Hampshire campaign headquarters of Vice Pres. Al Gore. The demonstrators were urging Gore to use his close ties to Occidental Petroleum to persuade the corporation not to drill for oil on the ancestral lands of the U’wa Indians in Colombia.
