RC had a recent post about some errors in von S's Science '04 article. Now Salon.com has an article on it too, being nice to us. Jolly good.
The main point made is a statistical one - read RC for that. A second one is the error in the initialisation procedure for von S's model run (not sufficiently spun up back to pre-ind). This causes a drift (down) during the sim, which over-estimates the variance.
