WSJ column forwards outdated climate info published in SuperFreakonomics

SUMMARY: Wall Street Journal columnist Bret Stephens advanced the claim made by Steven Levitt and Stephen Dubner in SuperFreakonomics -- which has recently come under criticism by economists and climate scientists for what they say are distortions in the book's climate change chapter -- that, in Stephens' words, "sea levels will probably not rise much more than 18 inches by 2100." However, this claim is apparently based on projections made in 2007 by the Intergovernmental Panel on Climate Change (IPCC) that did not include future changes in ice flow and therefore do not represent recent developments in climate science observations indicating that increased and accelerated ice sheet loss will cause sea levels to rise by more than previously projected.
