I just posted the following two comments on RealClimate.org in the
"Hit the Brakes" thread. They are somewhere after post #144.

In all this discussion, I’d like to explore one data point.

Question: When/if the polar ice caps completely melt, how much higher
will the oceans be?

Paul Blanchen and three other researchers did an analysis of Xcerat
Park in Mexico. The report (and an abstract and a short interview with
Blanchen) are in NATURE, pages 803 and 881, V458 (4/16/09).

Their focus was the sea rise change circa 121,000 years ago. They
measured that change (presumably when all polar ice had melted) at
about 7 feet.

Elsewhere on this site I’ve seen statements that the rise might be as
much as 35 feet. 7 feet MIGHT be sustainable; 35 feet clearly is not.

Does 7 feet seem reasonably accurate, or will it be more (assuming the
polar ice completely melts)?

On another part of the puzzle. John Holdren is quoted in the same
issue of NATURE (on page 819) as saying a $100 tax on carbon will
cause the price of gas to rise by 30c. That sounds affordable.
