Ron Clutz introduces a bit of sanity into the scare stories about Greenland:

 

The media blitz ahead of the Paris climate conference is well underway and you can expect sources like the New York Times to publish many stories along these lines. This one evokes the WWII headline, Paris is Burning, and it happens now to be all over Facebook.

What you get is not science, but a compelling human interest story with great photos about a team of researchers working to study rivers on the ice sheet, and then an appeal to share in their fears. A scientific report would at least provide some snippets of findings, and then provide contextual facts for people to interpret the significance of observations.

Instead of that, the story makes an incredible claim:

The scientific data he and a team of six other researchers collect here could yield groundbreaking information on the rate at which the melting of the Greenland ice sheet, one of the biggest and fastest-melting chunks of ice on Earth, will drive up sea levels in the coming decades. The full melting of Greenland’s ice sheet could increase sea levels by about 20 feet.

Not only is there no evidence presented, the article is silent about the contextual facts that contradict that claim.

Here is what you need to know, and what they should be telling you:

Of course, we must not forget that temperatures across Greenland since 2010 have been lower than they were in the 1930’s and 40’s.

Or that, according to ice cores in Greenland, the 19thC was the coldest period since the end of the Ice Age. Why anybody should be surprised a very small amount of warming since then baffles me.

    Baffled?
    You stated their motives at the beginning.

    Greenland isn’t melting this year, in fact it’s doing the opposite

    The scientific data he and a team of six other researchers collect here could yield groundbreaking information on the rate at which the melting of the Greenland ice sheet, one of the biggest and fastest-melting chunks of ice on Earth, will drive up sea levels in the coming decades. The full melting of Greenland’s ice sheet could increase sea levels by about 20 feet.

    Well, as the Greenland ice sheet accumulates ice during winter at one of the fastest rates globally, for it to remain in balance it’d be reasonable to expect it to lose it at a corresponding rate over the year. Part of that loss will be from glacial flow, but that rate is regulated by the accumulation, the more ice- the more flow. Sea level has been rising for decades, so we might expect it to do so for future decades. If the Greenland ice sheet melted, there would be a significant sea level rise.
    All in all, while their intention is to cause alarm, they are not saying anything that is beyond reason.

    This sort of ‘reporting’ is effectively little more than a projected lie. For those ’20 feet’ sea level rises to come to pass the entire Greenland ice sheet is required to melt – and that would take many thousands of years to occur.

    It’s like George Osborne triumphantly declaring ‘Only the Conservative party pledges to make every UK citizen a millionaire, with a guaranteed net worth of £1 million per person. (We’ll deliver this pledge no later than the year 4025) No body, group or organisation would be allowed to make such a preposterous claim in public or commercial life without expecting extreme censure from authorities, but what do we hear from climate experts like the RS or HadCrut? Not. A. Sound.

    They’re worthless junk headlines, which only reveal what little substance they actually have to report.

    Just watched a fascinating NOVA program: “Mystery of the Megaflood” about the creation of the Scablands of eastern Washington. 15,000 years ago, glacial Lake Missoula suddenly emptied sending as much water as Lake Superior into eastern WA. The pressure at the bottom of these tremendous ice-dams does not allow water molecules to expand and thus freeze. This leads to super-cooled water. As this water flows through minute cracks there is slight friction and enough raises the temperature which melts the cracks, enlarging them. At some point the ice dam blows out rather suddenly releasing any water buildup behind it. A geologist from Iceland discovered this mechanism for the ice-dam failures after one such episode there in the late 1990’s.

    It has nothing to do with atmospheric temperatures, but with enormous pressures created by the ice. And if there is a lake impounded behind it…….. It struck me as I watched, that places such as Greenland and Antarctica might be subject to these forces…..ya think?

    OT but slightly related.
    During speech by Lord Hunt, at the start of the broadcast of the House of Lords Climate Change debate today, the BBC put the following text on the screen.
    “According to the Met. Office, sea levels have risen by 10cm around the UK and 19cm globally A YEAR since the 1990’s”
    I suspect that what they meant was “10MM around the UK and 19MM globally, SINCE the 1990’s”.
    If so, the figures were were 200 times what they should have been.

      Yes, globally sea rise is about 1.9mm a year, not 19cm!

        So globally their figure is only 100 times the true figure, not 200!

        The incredible thing is, somebody at the BBC thought that 10cm/19cm p.a. was possible, and nobody corrected it.

        1mm and 1.9mm a year doesn’t sound nearly as impressive.

        You can see what they said on iPlayer. about 3m 35s into the programme:

        I have’t watched the rest of the debate yet, my blood pressure can’t take it.

        Thanks

        I’ve got a screen shot + will post tomorrow

    it is melting at a rate of about 287 Gt per year on average and a wide variance year to year, some with gains but most with losses (2002-2014). With a total mass of more than a million Gt, it will take a few thousand years to be gone altogether.
