The Economist (September 24)
Arctic ice is disappearing faster than previously thought. The ice is now estimated to be just half as thick as it was 1979 “and there is probably less ice floating on the Arctic Ocean now than at any time since a particularly warm period 8,000 years ago, soon after the last ice age.” Models had predicted that summer ice would disappear by century end. Instead “at current rates of shrinkage… this looks likely to happen some time between 2020 and 2050.”
