SOON AND MORNER: Sea-level rise data based on shoddy science

Got this article via junkscience.com.  The most interesting part of the article is about the climate models:

In an eagerly anticipated paper in the Journal of Climate, a group of scientists from the British Antarctic Survey documented how all of the 18 climate computer models that are used in the Fifth Assessment Report failed in the simple task of simulating the annual cycle and trends in the Antarctic sea ice extent. The authors found the majority of the climate models have too small a sea ice extent at minimum in February, while several of the models have less than two-thirds of the observed values at September maximum.

Even more devastating news is that the observed Antarctic sea ice extent over the past 30 years is showing an increasing trend, while most climate models produce decreasing sea ice extent. Such an obvious discrepancy from observed phenomena should once again cast strong suspicion upon rapid sea level change scenarios in the Fifth Assessment Report and render them void for use in public policy.
