Sea Level Rise Can't Be Stopped

riverat1 writes "Sea level rise won't stop for several hundred years even if we reverse global warming, according to a study published in the journal Nature Climate Change. As warmer water is mixed down into the oceans, it causes thermal expansion of the water. Under the best emissions scenario, the expected rise is 14.2 cm by 2100; under the worst, 32.2 cm from thermal expansion alone. Any water pumped from aquifers or glacial/ice sheet melt is added to that."

    It will be ok in North Carolina since their legislature said you can only use linear extrapolations of sea level rise to plan building in coastal areas. Guess they didn't get beyond simple algebra in school (no quadratic equations etc).

    Because, of course, the laws of nature obey your political ideology.

    Here's news, moron, the Universe doesn't give a fuck about Liberal vs. Conservative, Socialist vs. Capitalist. It does not fucking care. If pumping millions of years of sequestered CO2 into the atmosphere in the space of two centuries is going to cause serious climactic changes, it is absolutely fucking irrelevant who you fucking vote for, or whether you masturbate to Vladimir Lenin or Ayn Rand.

    Fucking hell, you ideological fanatics are a tiresome, mentally handicapped lot. Don't like evolution because you think it falsifies your religion. Don't like acid rain or climate change because it means there are consequences to wide-scale and uncontrolled industrial activity. Don't like regulations because it kills your particular get-rich-quick-while-fucking-the-economy scheme.

    Is there any part of you at all that isn't a selfish, greedy piece of stupidity? Is there any part of you that gives the least little fuck for anyone other than yourself? Or are you really the vile repugnant sociopathic troll you appear?

    From the parent post

    Well, we only have 88 years to deal with a foot rise in water. Damn, that's devastating, we'd better get right to work.

    From the summary

    ...32.2 cm from thermal expansion alone...

    I know it is easier to ignore reality, but I think the parent poster has gotten so used to ignoring science that he ignores the clear language in the article summary. Here is a fact: Most sea level rise will come in the end from melting glaciers. And the melting is accelerating.

    So the "twenty feet by 2100" thing is gone now then is it Mr. Gore, cause, gosh, that sure sold a lot of movies books and carbon taxes.

    Except that Gore didn't actually say twenty feet by 2100 in his movie. Here is a link to the transcript (pdf) of An Inconvenient Truth. I believe the passage that is often referred to occurs when Gore shows the maps of water inundated coast lines. Here is the transcript of that part of the movie:

    If Greenland broke up and melted, or if half of Greenland and half of West Antarctica broke up and melted, this is what would happen to the sea level in Florida. This is what would happen in the San Francisco Bay. A lot of people live in these areas. The Netherlands, the low-countries: absolutely devastating.

    The above statement is basically true. If you broke up the entire Greenland ice sheet, the rise in sea level would be catastrophic. Mr. Gore does not say this will happen in the next 100 years. It is a conditional statement. If something happens, then something else will happen. The time scale is not certain, though given recent trends in melting, three feet by 2100 is not unlikely. A basic search of recent literature will support this.

    I'm not a climatologist either but I have been interested in it for at least 30yrs. Having said that, wtf does the "MMGW" acronymn stand for?

    The only "theory" I know of concerning storms other than the obvious more heat == more turbulance is that the N. Hemisphere jet stream will ocillate more and the ocillations will move slower. This will increase the likeleyhood of Atlanitic hurricanes being "killed" by the sheraing of the jet stream, but on a global scale the monsoon rains will increase and the sub-tropic deserts will expand due to the more intense Hadley cells (Hadley cells = convection currents on either side of the equator that pump moist air up over the tropics where it dumps the moisture as rain after which the dry dry air falls down on the sub-tropical deserts). In other words heat will increase the amount of water traveling through the hydrological cycle, this is already happening as evidenced by the atmosphere already holding 4% more water vapour than it did 40yrs ago. Note also that the increase in water vapour is more evidence of a warmer planet since the atmosphere is basically chemically staurated with H20 and the only way to increase it is to raise either the temprature or the pressure (and I don't think gravity is any stronger than it was in the 70's).

    So yeah, to a certain extent the jury is still out on storms. It's pretty certain we will get more floods/snow and more droughts/heatwaves but it won't necassarily comes via hurricanes and blizzards.
