Greenland Ice Sheet Melting No Faster Than Last Century

Ralph Alexander reviews a new study on Greenland’s ice sheet:

The climate doomsday machine makes much more noise about warming-induced melting of Greenland’s ice sheet than Antarctica’s, even though the Greenland sheet holds only about 10% as much ice. That’s because the smaller Greenland ice sheet is melting at a faster rate and contributes more to sea level rise. But the melt rate is no faster today than it was 90 years ago and appears to have slowed over the last few years.

Full story here.

Below is the key graph, with Ralph’s comments:

Temperature records confirm that it was just as warm in Greenland between the 1920s and 60s as now.

This latest study by Mankoff et al indicates that the ice cap was melting at a similar rate back then as well.

According to the IPCC, melting of the Greenland icesheet was contributing 0.63mm a year to sea level rise, just over two inches per century. Given that the 19thC was the coldest era in Greenland since the ice age, there should be little surprise or worry about this.

Nothing that is happening is “unprecedented”, nor is the ice loss accelerating. Indeed the opposite seems to be happening.

All indications suggest that the ice sheet will actually start growing again, when the Atlantic Multidecadal Oscillation, AMO, turns negative again.

    I’d love to see the chart with mean and SD(1&2) limits. As it is my MkI eyeball suggests that the losses have not been more than 2SD from the mean – which I was taught was the time to set an ‘action point’. But, quite happy to be wrong…

    This post from wuwt may be relevant.

      And this chart with mass recovery since 2012

      “…post from wuwt…”

      It is interesting – but not surprising – that the underlying report soon loses all focus on the new finding and automatically reverts to the mindless reiteration of dogma:

      “…the melting of the permafrost will [sic] release methane…”

      One can almost see the nervous fingers of the true believers frantically twisting their worry beads. “Come On, Catastrophe!” they keep muttering.

      Meanwhile, it is kind of chilly in the Arctic:

    Nobel Prize Winner’s Richard Feynman’s quote on the banner is oh, so prescient: “If it [a scientific hypothesis] disagrees with experiment, it’s WRONG.”

    The hypothesis is a proposed theory. Experiment and data collection follow to either prove or disprove the hypothesis.

    That is the crux of science. Either it is or it is not or cannot be explained by the data, experiments or abilities at this time. Science IS NOT settled, by ongoing.

    When I click the full story “here” link, I get an error message.

    We are not told what the upper two plots are on the chart.

    Warmists will immediately pick on the fact that peripheral glaciers are not included, so this article is useless material in any debate.

    Perhaps if I could see the full story these points would be answered, but as it is I cannot.

    There is an error in the link but I managed to open it in Firefox. Try this link:

      That is not the right paper. A search in your browser for “Science under attack” and select “Ralph Alexander” should find it – doo scroll down past the fist bit.

        That worked thanks

    The rate of sea level rise has been stable for a hundred years. All of this “ice sheet melting” talk, with no change in SLR rate observed, says they have something very wrong. Either there is no significant melting, or it has no effect on SLR. Either way, the doomsday cult has a big problem.

    We’re all being relentlessly gaslighted. At what point does this become fraud?
