lightblueline

National Geographic reports that the sea level rise in this century will be somewhere between two and a half and six and a half feet. Of course, looking at the next five-hundred years (which is what lightblueline suggests we do, since we do that anyhow for floods and earthquakes) this would translate into a rise between twelve and a half and thirty-two and a half feet. Split the difference and you have about the seven meter rise lightblueline has always been focused on.

Stefan Rahmstorf at Potsdam University (March 2007) discusses the IPCC sea level numbers:

What is included in these sea level numbers?

Let us have a look at how these numbers were derived. They are made up of four components: thermal expansion, glaciers and ice caps (those exclude the Greenland and Antarctic ice sheets), ice sheet surface mass balance, and ice sheet dynamical imbalance.

Scientific American (February 2008) outlines the risk that the major ice sheets (particularly the West Antarctic Ice Sheet) hold for potential rapid sea level rise. This piece is written by Robin Bell at Columbia University.

Key Concepts:
The land-based ice sheets of Greenland and Antarctica hold enough water to raise global sea level by more than 200 feet.

Latest scientists' views of sea level rise

Sea level rise prediction estimates are running toward the top limit and beyond the IPCC predictions.

'Losing battle?' Calif. sea level rising

The video is available above.

"Are California's beaches shrinking? According to a recent EPA report, the sea level is rising along most of the U.S. coastlines. So what does that mean for Southern California?

California's 1,100 miles of coastline is home to some of the most expensive real estate in the world.

Twenty five polar ice experts met at the University of Texas, Austin, in March of 2007 to examine the state of scientific knowledge about the potential contributions of the West Antarctic ice sheet to future sea-level rise.

The report of the West Antarctic links to Sea Level Estimation (WALSE) Workshop states that more attention needs to be paid to this element of the climate system.

The National Environmental Trust has posted a set of animations showing how the IPCC-predicted sea-level rise and a hurricane would effect cities up and down the eastern seaboard. The site has a load of educational information about climate change and its environmental effects.
