NASA Climate Scientists predict a 3m Sealevel rise.

In what may prove to be a turning point for political action on climate change, a breathtaking new study casts extreme doubt about the near-term stability of global sea levels.

The study—written by James Hansen, NASA's former lead climate scientist, and 16 co-authors, many of whom are considered among the top in their fields—concludes that glaciers in Greenland and Antarctica will melt 10 times faster than previous consensus estimates, resulting in sea level rise of at least 10 feet in as little as 50 years. The study, which has not yet been peer-reviewed, brings new importance to a feedback loop in the ocean near Antarctica that results in cooler freshwater from melting glaciers forcing warmer, saltier water underneath the ice sheets, speeding up the melting rate. Hansen, who is known for being alarmist and also right, acknowledges that his study implies change far beyond previous consensus estimates. In a conference call with reporters, he said he hoped the new findings would be "substantially more persuasive than anything previously published." I certainly find them to be.

To come to their findings, the authors used a mixture of paleoclimate records, computer models, and observations of current rates of sea level rise, but "the real world is moving somewhat faster than the model," Hansen says.

3 meters doesn't sound a lot, but it would be absolutely devastating to coastal communities. It would make a big difference to my city, although we would have to have a rise of over 90 meters before my house was reached, but most of my town and the city would be gone at that point. Scary thought!

It is scary Stirkles. 3m is 10 feet! It would cover a lot of my city too although I am higher up than that.

It wouldn't reach me but 10 feet is approximately one storey, loads of the west coast would be toast and unworkable. Think of the extra load on bridges or roads being permanently under water... the new surge from storms *shudders*

There's islands out there now that are already barely above sea level... they'll be gone, just *poof* soon to be a new Atlantis Sad

And the hue and cry to stop pollution based warming which leads to the ice melts causing this have been going on and ignored since the 1890's

Humanity,,,,WTF is wrong with you? (present company excluded), but the majority of the population, and the greed mongers in charge that chose to pass it along for each new generation...... Evil or Very Mad

I am particularly taken by the saying: "We didn't inherit the world from our forebears, we borrowed it from our children."

So true!
