David Bidstrup: Greenland’s going fast!!!

There’s a man in Tasmania who runs a blog dedicated to climate catastrophes and other gloom and doom. He reports that “scientists” declared 10 billion tonnes of ice were lost from the Greenland ice sheet over 2 days last week and this would flood the state of Florida with 5 inches of water if the melt could be spread over the states area.

The “report” has all the usual climate catastrophe warnings about the end of the world – ice melts faster in the north for some reason, the “hot” winds from the recent heatwaves in Paris etc. “moved north and melted the ice”.

The table below gives the details.

When water freezes it increases in volume by 10% so 10 billion tons of ice is actually 10.88 cubic kilometres in volume. This is why melting sea ice is not a threat to sea levels. When it melts it produces 10 cubic kilometres of water. When this is spread over the area of Florida the depth is 0.059 metres or 2.3 inches so the report overstates the “problem” by 100%.

The ice sheet has a surface area of 1.71 million square kilometres. The removal of 10.88 cubic kilometres would equate to a surface level change of 0.0064 metres or quarter of an inch. I wonder how they measure these things.

The ice sheet has a volume of 2.9 million cubic kilometres. The 10.88 that “melted” comprises 0.00034% of the volume. At that rate of “melting” it would take just over 3 ½ years to lose 1 percent.

If all the two day meltwater went into the oceans the sea level rise would be 0.000028 metres or 0.0011 inches. How would you measure that?

The report does not mention that Greenland has cycles of freezing and melting and that proper records show that nothing is changing. Anyway, global cooling will fix it.

I don’t think it’s time to get out the gumboots.

    And on top of that, on an annual basis, Greenland ice INCREASES by a similar amount.

    Better still. If you convert 0.000028 metres to the everyday, you get 28 micro-metres, which is too small to be measured with a standard ruler. Basically, it is less than spilling a thimble of water on a kitchen floor.

    A classic green activist tactic straight out of the Greenpeace handbook: quote large and alarming figures, but under no circumstances put them in context so that the reader can see for themselves that they are……..inconsequential.

    Ah, so that’s why the ice cube floats on my gin and tonic, and why the glass doesn’t overflow when the ice cube melts.
    When people speak of loss from the Greenland ice sheet, do they mean from ice over the landmass, or sea ice at the periphery, I wonder?
    Thanks David – another beaut post.

    Greenland temperatures, and the icecap, are cyclic with the AMO. As you can see the AMO has an almost square wave cycle and has been on a plateau for about the last 20 years.

    You can also see pretty clearly what is going to happen when the AMO goes over its next cliff, as occurred in 1900 and 1960.

    Tezza, doing a Google search uncovers this from Answersdotcom:

    Does ice float in alcohol?
    It depends on the alcohol and the percent of alcohol in the solution in which the ice is placed. Ice has a density of 0.9167 g/cm³ at 0°C. As ethyl alcohol is the one most people think of, lets use it as an example. Ethyl alcohol (pure) has a density of 0.789 g/cm3 so ice would sink rather quickly. It is not until room temperature (20 °C) alcohol/water solutions approach 50% that the densities of the solution would be high enough for the ice to float.

    Also this link tells the Specific Gravity of various liquids, including pure water (1.000)and sea water (1.025) at 4 degC, and ethanol (0.787) at 25 degC. So at least it shows that you are not drinking 100% alcohol where the ice would sink.

    But some groups would accuse you of adding to the CO2 emissions by drinking tonic, and would direct you to Irish beers that use Nitrogen to get the every fine bubbles.

    Alcohol proof is a measure of the content of ethanol (alcohol) in an alcoholic beverage. The term was originally used in England and was equal to about 1.821 times the alcohol by volume (ABV). The UK now uses the ABV standard instead of alcohol proof. In the United States, alcohol proof is defined as twice the percentage of ABV.

    PS In the Caribbean I bought a bottle of 150 proof rum with the warning on it to not use near open flame.

    Early Warnings of Climate Change Catastrophe – 1982

    James Kane, Dept. of Energy, 2.07: “Even the pessimists the ones that predict these terrible cases, aren’t really predicting large effects for 50 years or so, so I don’t think that we should pour money on this problem in the short run.”

    Tezza, from Wikipedia.

    Bacardi 151 is a discontinued brand of highly alcoholic rum made by Bacardi Limited of Hamilton, Bermuda. It is named for its alcohol proof level of 151, that is, 75.5% alcohol by volume. This is much higher than typical rum at 35%–40%. Bacardi 151 was sold in the United States from at least 1963 until 2016, when its production was discontinued.

    I bought a bottle in 1981 for something like US$ 3.00. Dirt cheap.

    So the ocean’s rise 28 microns in two days in the nothern hemisphere due to 10km3 of ice melting. How much ice was formed in the Antartic during the same 2 days?

    I suspect that given the current polar blast effecting the southern states of Oz, at least 10km3. Its the Yin to their Yan.

    Greenland has more ice now than ever in the Holocene.
