I recall reading a paper about this a few months ago but cannot find it. I've researched a number of sources about SLR, but they do not address the issue. What does the science tell us? | |

I refound what I was looking for in Dr Peter Hoath's guest post, "Visual Depicitions of Sea Level Rise." http://www.skepticalscience.com/Visual-depictions-of-Sea-Level-Rise.html | |

Thermal expansion would be uneven, so you wouldn't have an even sea rise. So if it was a fast melting you would get a bulge in the Atlantic for quite a few years, but if it were slower, then it would have time to distribute to the other seas/oceans. Some research: Melting Greenland Ice Sheets May Threaten Northeast United States, Canada Response of the global ocean to Greenland and Antarctic ice melting (I think this one represents an extreme case) | |

Thanks for the links. The paer that I read a few months ago was about concentrations of sea level increases in the euqatorial regions of the Pacific. One of these days I'll restumble upon it. | |

One interesting misunderstanding some people have is the difference between the speed a wave travels and the speed that water can physically move. You might get someone on a forum suggesting that water will quickly distribute across the Earth because waves travel fast. But of course a wave is primarily the transmission of energy and water isn't really moved much (it actually moves in a circular motion in the vertical plain) by a wave. Something to look out for in some discussions. | |

Bamber and Riva (2010) will answer your questions. Available free at the cryosphere. | |

No it isn't, pretty graph here!
Shows some similar characteristics to temperature - e.g. some areas have falling sea levels, but most areas are rising and the fastest rise is bigger & more widespread than the fastest fall. In reality, the total volume of sea water is going up, and eventually the 'rise' signal will swamp the 'noise' signal and the areas of falling seas will shrink... But until then, expect some of the climate liars to pounce on the few bits where it's falling and ignore everything else. |
