    Refugee crisis?

    That, Terangeree, is what all of the panic over refugees is about, global warming producing flotillas of millions.

    “There’s so such thing as global warming, and we’re not causing it, but we don’t want the refugees that it displaces.”

    At least, that’s the tune that Abbott (dog-)whistles for the happy campers who follow him.

    Read an interesting article, “High and Dry” in the print version of New Scientist (4 May 2013). It predicts that, if the Greenland ice sheet melts, sea levels along the Greenland coast will fall by something like 100 metres. (Yes, fall.)
    The explanation is that

    any large mass on the earth’s surface exerts a significant gravitational pull on any water surrounding it.

    Even the the north of Scotland would see a 3 meter drop.
    Changing wind and current patterns will also have an effect on relative sea level rise around the world.
    Ongoing rebound after the last ice age will also have an effect. Keep in mind that places like New York that was outside of the ice sheet actually rose during the ice age (and are now sinking) because the weight of the ice pushed ground out and up from the area covered by the ice sheet.
    Buy water front property with title down to the water’s edge in Northern Scotland. Sell inNY.

    I would prefer,when I am conservation minded to dwell on engineering works like Abbot’s Point or whatever it is called.To be just opposed to it is a stuck in the mud reality means,one couldn’t get round to deciding that drenching should be a no-no,and some other simpler,proposals could in fact be cheaper.One of the contributors here talks about May and Scotland,whereas,Palmer is here now and approved,and I can tell you this.Even if I agreed with you here a 100%,as someone who has outlined design engineering before and had it taken up,I suffer a lot of angst hurt,depression about that because of outcome.I feel,only enlightened by the meerest of details,that Palmer has got it through too easy.That is both the mining matter,and the dredging matter,whereas the rail becomes a permanent thing for a long time,that does nothing but move coal ! Whereas a port doesn’t need to be dredged when concrete blocks can settle onto the port sea level.Hydraulics can lift up ships and lower them,swing them round to adjust to very harsh conditions .Concrete blocks themselves could be on definable and real sea rails..And there is no prospect that the ocean and seas are going to get less active. So why do these designers,just commit design to dredging!?If there is no way to penalise such designing because it is jointly owned by business and government,then, the equal of a penalty to the professional groups allowing this garbage design needs enacting.

    Emotional state lent itself to drenching rather than dredging.I am not doing well fighting against the senility that government and media decide is positive.There maybe other errors.

    The differential patterns of sea level rise in the Pacific over the last 20 years (the period covered by the map) are largely a product of the cluster of La Nina events since 2007 (during La Nina years, easterly winds are stronger through the tropical Pacific, and water tends to “pile up” against the ocean’s western side). There’s no particular reason to expect that pattern to persist into the future.

    Correct me if I am wrong but aren’t the gravitational effects of large masses of (impounded) water well understood from studies on large dams? Thanks for the heads-up on falling sea-levels, John D.

    Mention has been made a few times about adverse changes in sea-water pH – but what will be the likely effects on weather and on marine ecology from the diluted salinity of sea-water?
