<![CDATA[Grist - Comment Feed for Sea-level rise could be double IPCC projections]]> Grist Comment Feed en Comment #1 by Sam Wells http://www.grist.org/article/greenland-study/ Tue, 12 Feb 2008 11:27:53 -0800 http://www.grist.org/article/greenland-study/1 Good point, but IPCC said ice model was bad

I think any prediction a century out is rather bogus, but it is true the rate of existing erosion of arctic ice and northern glacial ice is at a much faster rate than anticipated by IPCC.

One thing causes me some difficulty because most polar ice melt models assume the Earth is flat; that is, if "x" many billion tons of glacier ice melts, the ocean would rise uniformly as "y" in millimeters per year, similar to pouring water into a cookie sheet for baking.

Well the Earth is not flat, nor is it perfectly spherical. Trust me, the ocean turns out to be quite lumpy.
