Experts are worried because a long-term slow decline of ice around the north pole seems to have sharply accelerated since 2003, raising fears that the region may have passed one of the "tipping points" in global warming. In this scenario, warmer weather melts ice and drives temperatures higher because the dark water beneath absorbs more of the sun's radiation. This could make global warming quickly run out of control.
