An eloquent statement from the man who first announced global warming in the U.S. Congress, James Hansen, director of the NASA Goddard Institute for Space Studies, published in The Guardian. An excerpt:
". . . we have used up all slack in the schedule for actions needed todefuse the global warming time bomb. The next president and Congressmust define a course next year in which the United States exertsleadership commensurate with our responsibility for the presentdangerous situation.
Otherwise it will become impractical toconstrain atmospheric carbon dioxide, the greenhouse gas produced inburning fossil fuels, to a level that prevents the climate system frompassing tipping points that lead to disastrous climate changes thatspiral dynamically out of humanity’s control."
