Copenhagen: James Hansen fields a question, calls for phase out of coal use

Copenhagen, Denmark. March 11, 2009

James Hansen fields a question during one of the many parallel sessions during the Copenhagen climate conference, a meeting aimed at consolidating the new scientific findings that have emerged since the fourth IPCC report of 2007. He recommends phasing out coal use as part of a strategy to avoid the positive feedbacks which emerge as the climate warms.
