excerpt:

Climate scientist James Hansen has fired a new salvo in the climate wars. In a new paper, Hansen and colleagues warn that the current international plan to limit global warming isn’t going to be nearly enough to avert disasters like runaway ice-sheet melting and consequent sea-level rise. Hansen told reporters at a press conference yesterday that he hoped the paper—to be published online this week—would influence global climate talks this December in Paris and encourage negotiators to reconsider their goal of keeping warming to less than 2°C above preindustrial levels, a laudable but insufficient target, some scientists say.
