Just like Archimedes discovered millennia ago, it is well known today that the Arctic ice cap displaces it’s own weight in the water so that when it melts it will not cause a rise in global sea level.
Surprisingly, the National Science Foundation has just figured this out (thanks to someone complaining about it) and has issued a correction to their sea ice page.
The error was first pointed out by commenter Steven Skinner on WUWT on March 25th 2010, who wrote:
The NSF, the U.S. Office of Naval Research, and the Japanese government cooperated in funding a research project called SHEBA (Surface Heat Budget of the Arctic) back in 1997. Considering the big names in funding I was surprised they allowed the conclusion in the last sentence past scientific proof reading before publication. The bit from ‘melting sea ice…’
It’s fixed now, see the BEFORE and AFTER.
WUWT reader Dave Burton, who called NSF on the error and asked for a correction writes in an email to them:
Since the error was on your site for over 6.5 years, misleading readers into believing that melting sea ice contributes to coastal sea level rise, I think it is important that you identify the error on your site, with a footnote which explains what was wrong with it.
I always wondered why I’d get the occasional angry email claiming melting Arctic sea ice would raise sea levels dramatically and “why don’t you get it?” …to which I’d reply “look up the principle of buoyancy”. Now I know.
