    The Secret of Sea Level Rise: It Will Vary Greatly By Region by Michael D. Lemonick: Yale Environment 360

    For at least two decades now, climate scientists have been telling us that CO2 and other human-generated greenhouse gases are warming the planet, and that if we keep burning fossil fuels the trend will continue. Recent projections suggest a global average warming of perhaps 3 to 4 degrees C, or 5.4 to 7 degrees F, by the end of this century.

    But those same scientists have also been reminding us consistently that this is just an average. Thanks to all sorts of regional factors — changes in vegetation, for example, or ice cover, or prevailing winds — some areas are likely to warm more than that, while others should warm less.

    What’s true for temperature, it turns out, is also true for another frequently invoked consequence of global warming. Sea level, according to the best current projections, could rise by about a meter by 2100, in large part due to melting of the Greenland and West Antarctic ice sheets. But that figure, too, is just a global average. In some places — Scotland, Iceland, and Alaska for example — it could be significantly less in the centuries to come. In others, like much of the eastern United States, it could be significantly more.

    SOTC: Sea Level

    The Contribution of the Cryosphere to Changes in Sea Level
    Global sea level rose by about 120 meters during the several millennia that followed the end of the last ice age (approximately 21,000 years ago), and stabilized between 3,000 and 2,000 years ago. Sea level indicators suggest that global sea level did not change significantly from then until the late 19th century when the instrumental record of sea level change shows evidence for an onset of sea level rise. Estimates for the 20th century show that global average sea level rose at a rate of about 1.7 millimeters per year. Satellite altimetry observations, available since the early 1990s, provide more accurate sea level data with nearly global coverage and indicate that since 1993 sea level has been rising at a rate of about 3 millimeters per year. Climate models based on the current rate of increase in greenhouse gases, however, indicate that sea level may rise at about 4 millimeters per year reaching 0.22 to 0.44 meters above 1990 levels by the period 2090-2099 (IPCC 2007).

    they dont even think we know what makes the tides.

    They just dont understand sceince.

    They prefer bible stories to seintific data and facts.

    How much is sea level rising?

    How much is sea level rising?
    Link to this pageThe skeptic argument...
    Sea level rise is exaggerated
    "We are told sea level is rising and will soon swamp all of our cities. Everybody knows that the Pacific island of Tuvalu is sinking. Around 1990 it became obvious the local tide-gauge did not agree - there was no evidence of 'sinking.' So scientists at Flinders University, Adelaide, set up new, modern, tide-gauges in 12 Pacific islands. Recently, the whole project was abandoned as there was no sign of a change in sea level at any of the 12 islands for the past 16 years." (Vincent Gray).

    What the science says...
    Select a level... Basic Intermediate
    A variety of different measurements find steadily rising sea levels over the past century.


    Sea level rises as ice on land melts and as warming ocean waters expand. Sea level rise mutually corroborates other evidence of global warming as well as being a threat to coastal habitation and environments.

    The blue line in the graph below clearly shows sea level as rising, while the upward curve suggests sea level is rising faster as time goes on. The upward curve agrees with global temperature trends and with the accelerating melting of ice in Greenland and other places.

    Because the behavior of sea level is such an important diagnostic aid for tracking climate change, skeptics seize on the sea level record in an effort to cast doubt on this evidence. Sea level bounces up and down slightly from year to year so it's possible to cherry-pick data falsely suggesting the overall trend is flat, falling or linear. You can try this yourself. Starting with two closely spaced data points on the graph below, lay a straight-edge between them and notice how for a short period of time you may create almost any slope you prefer, simply by being selective about what data points you use. Now choose data points farther apart. Notice that as your selected data points cover more time, the more your mini-graph reflects the big picture. The lesson? Always look at all the data, don't be fooled by selective presentations.

    I love seintific data. kramerific data too. I never did like georgeous data though.

    what a hypocrite you are. I still remember that Nature article on biomass that wasnt statistically significant and gave totally different results with a small change of start and end points. You agreed at the time that it shouldnt be used because of its faults but lo and behold--- you were quoting it like gospel the very next day! Your standards are showing again.

    This is hysterical stuff............as this scientist says about global warming, "Complete nonsense.......fiction...........taken from a 'cult ideology'."!!!!!!!!


    All the global warming FAITHERS predicted that Britain would be burning up all winter in 2010-2011............this guy predicted historic cold. Turns out? Coldest winter in England in like 1,000 years!!!!!:fu::boobies::fu::boobies::fu::boobies::fu:


    k00kiest thing of all? These FAITHERS truly believe this shit they post up all the time!!!!!
