There has been a lot of vocal complaining from the right-wing, climate denialists about some small errors and inconsistencies in the IPCC’s 2007 Fourth Assessment Report. Scant attention has been given to significant underestimates of some impacts in the 2007 report. You don’t have to delve far into the literature on sea level rise to find that many experts find the IPCC’s estimate of 20 – 60 cm rise by centuries end to be much too low.

This article at the website Real Climate titled Sealevelgate neatly summarizes the controversy. It is by Stefan Rahmstorf, an oceanographer at the University of Potsdam in Germany.

Let me propose this maxim:

For every overstatement of man’s impact on the earth’s climate by the IPCC, there is an equal and opposite understatement of some other impact.
