I thought..."Anonymous, I am not sure you are right. I thought that ice floated, with a ratio of 1 to 9. In other words, 8/9 of ice mass was above the water, with 1/9 above the water."<BR/><BR/>From Wikipedia:<BR/><BR/>"The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least to seem lighter."<BR/><BR/>Water expands when it freezes, meaning it gets less dense, meaning the same mass takes up more volume. That's why ice floats. If all the ice that floats on the sea melts, nothing happens. If you don't believe me, get a glass of water, some ice, and conduct your own experiment.<BR/><BR/>"BTW, you don't seriously expect a surge barrier to protect London from rising sea levels. The Greenwich barrier isn't there to protect us from global warming."<BR/><BR/>Lets review what I said:<BR/><BR/>"Sea level rise over the next century will come primarly from thermal expansion of the seas and will not be sufficient to flood London, though the floodgates will be operated more often to prevent tidal and/or storm driven surges up the Thames."<BR/><BR/>I think that says that the seas will rise some, and thus the floodgates will need to be used more often because the base level a surge would build upon will be higher, even though the net rise will not be enough to flood London in and of itself, all during the coming 100 years. I don't think it says that the floodgates will hold back a rise sufficient to flood London.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2948538160252327076.post-13371359114947060202007-05-09T17:44:00.000+01:002007-05-09T17:44:00.000+01:00Anonymous, I am not sure you are right.

If the polar cap melts, at least some of this melted ice would raise sea levels. Moreover, Greenland is defrosting, so the combined effects would probably cause London some problems.<BR/><BR/>BTW, you don't seriously expect a surge barrier to protect London from rising sea levels.

The Greenland ice sheet and the various Antarctic ice sheets may melt if CO2 emissions aren't reduced, but they will take much longer to do so. Sea level rise over the next century will come primarly from thermal expansion of the seas and will not be sufficient to flood London, though the floodgates will be operated more often to prevent tidal and/or storm driven surges up the Thames.<BR/><BR/>I think you are well-meaning on this issue so I suggest that you gain a better understanding of the predictions as they currently stand.Anonymousnoreply@blogger.com
