The Rahmstorf Method
The so-called "Rahmstorf Method" for predicting accelerated sea level rise has been thoroughly
demolished by a number of other scientists, and by the progression of time. Here are some
- A Semi-Empirical Approach to Projecting Future Sea-Level Rise, by Stefan Rahmstorf (2007), in Science [full text, or here].
- Science published two highly critical comments on Rahmstorf (2007) [or here].
- Rahmstorf's response to the two critical comments on Rahmstorf (2007) [or here].
- Global Sea Level Linked to Global Temperature, by Vermeer & Rahmstorf (2009)
- Tom Moriarty has done careful, in-depth demolitions of Rahmstorf 2007 (here),
and Vermeer & Rahmstorf 2009 (here).

the giant German reinsurance company, which has a pecuniary interest in promoting climate alarmism, to justify higher reinsurance rates

"Rahmstorf (2007) presented an approach ... based on a proposed
linear relationship ... We find no such linear relationship. Although we
agree that there is considerable uncertainty in the prediction of future
sea-level rise, this approach does not meaningfully contribute to
quantifying that uncertainty."

"...this statistical analysis (Rahmstorf, 2007) is based on an
application of statistics ... violating basic assumptions of the
statistical methods used."

"In hindsight, the averaging period of 11 years that we used in the 2007 Science paper was too short
to determine a robust climate trend..."
(Stefan Rahmstorf's 2009 mea culpa, on the RealClimate blog site.)
"It turns out that Rahmstorf has pulled an elaborate practical joke on the Community..."
