Greenland\’s melting!

What excellent news this is:

Research has shown that the 1.7 million kilometre square ice sheet could melt entirely over several thousand years if temperatures continue to rise unchecked, causing sea level rises of up to seven metres.

Now a study from the Met Office Hadley Centre shows that there could be thresholds in melting which, once crossed, could prevent the ice sheet from re-growing to its former extent even if the carbon dioxide concentrations driving climate change are reduced to pre-industrial levels.

Met Office scientists urged action to cut CO2 emissions now, to prevent the ice melting past the tipping points and causing large sea level rises in the coming centuries.

Climate modelling combined with a 3D simulation of the ice found that if the sheet melted by more than 15 per cent, which could occur within 300 years, it would be locked into further decline from which it could only recover to around 80% of its current size.

No, really, this is very good news indeed. Note the \”several thousand years\” and \”300 years\” in there.

Firstly, this puts the kibosh on those alarmists who keep telling us everything is going to drown next Wednesday lunchtime. Secondly, well, 300 years: one hell of a lot has happened since 1700 and we can pretty much assume that one hell of a lot will happen between now and 2300. And as for \”several thousand years\”, well, that\’s pretty much the length of western civilisation so far. You would really have to be pretty brave to say that the Second or Third dynasties of the Pharoahs should have changed their behaviour because of their effect upon us.

Further, we know from the IPCC\’s own reports that the world in 100 years is going to be between 5 and 10 times richer than it is now. Projecting on from their model (the A1 one) we can also expect that in 300 years it will be some 7,000 times richer (that looks alarming but that is indeed what a 3% annual growth rate does over the timescale if I\’ve used the calculator correctly) and if \”several thousand\”. well, the calculator breaks down but it\’s well over the 6 million times that a millenium would bring.

All of this puts Greenland melting into the category of \”we don\’t care about that\” for if it does indeed happen then it\’s so far in the future that the rich bastards there can deal with it.

Which is good news of course.

  1. Of course, the world won’t be five or ten times richer in 2100 if the IPCC get their way…

  2. I understand that Greenland went through a warm period between the 9th and 14th centuries, when the ice retreated and it was able to sustain a larger population.

    Also it seems to have withdrawn from the EC in 1985.

  3. John, yes; and while I don’t have the reference, the melting at the coasts cas been revealing the plants which grew there 1,000 years ago.

    There is a Prof who, every time he hears about retreating glaciers asks “And what did they find”?

    So far they have found the remains of farmed plants in Greenland, abandoned silver mines in the Tyrol, and fossilised trees in northern Siberia, all proof that up to a millenium ago, these areas were ice-free.

  4. Research has shown that the 1.7 million kilometre square ice sheet could melt entirely over several thousand years if temperatures continue to rise unchecked…

    This is very good news, because temperatures haven’t risen unchecked and they won’t rise unchecked.

    In fact, the world is cooling rather more rapidly than it warmed over the last century: the average temperature drop over the last ten years has wiped out the supposed rise over the last century.

    We should probably be rather more worried about the Greenland ice-sheet increasing in size…

  5. If we keep getting richer as you say, my grandkids will be living on Mars, and won’t give a stuff. Or slothing about in a dirigible because their “work” does not require them to be tethered to a city by the sea.

  6. > We should probably be rather more worried about the Greenland ice-sheet increasing in size…

    Ice Sheets need Snow to increase in size and if it’s too cold it won’t snow on them.

  7. Ice Sheets need Snow to increase in size and if it’s too cold it won’t snow on them.

    I’ve never been too convinced by the “it’s too cold to snow” argument ever since I stood outside in a Russian blizzard in minus 20 something. True, the temperature does rise quite a lot when it snows and is much colder afterwards, but it is still possible to snow when it is effing cold.

  8. Tim Newman, you are right, as anyone who lives where I do (Canada) knows all too well.

    I just love it when people with no experience express opinions. Even better, I love it when people express a horror of ‘Global Warming’ without living in a cold climate.

    I do not for a minute believe in man made ‘Global Warming’, but if I’m wrong, that’s fabulous – the entire North West Territories and Yukon available for farming. India is 1,269,338 sq mi., the NWT is 1,171,918. There is no possible scenario which will lose us all or even most of India, but in many we will gain most of the NWT.

    Shall we also consider Siberia?

    Most of the world’s usable land mass is in the north – but for our current state of Global Cooling.
