IPCC Get It Wrong

Another set of projected vs. observed data comparisons which one can make is the rise in sea levels. The IPCC has predicted a sea level rise of about 17 mm over the time period 1990 - 2000.

We have a good dataset from the TOPEX/POSEIDON satellites, and from this data we get an average rise of 2.81 mm/yr. Or a rise of 28.1 mm over a ten year period.

The observed dataset is slightly off, as it covers the period 1993 - 2002, and as the rise in sea levels should accelerate over time, one would expect it's results to be slightly higher than the predicted values, but not by this degree. Also the satellite data is uncorrected for pressure. Once again, this may alter the results slightly. However, it isn't unreasonable at this point to say that the IPCC have underestimated the degree of rising sea levels.
