An Iceberg As Big As Delaware–Should We Be Worrying?

An iceberg as big as Delaware!   For those of you that are saying, “what’s a Delaware,?” — it is the second smallest State of the USA’s 50 States.   Even so, an iceberg that big is really impressive.  If it ran into the Titanic, the ship’s orchestra would probably not have had time to play for the people before the ship sank. (That’s from the movie– I am not sure the orchestra really played while the ship sank.)

Around 12 July this year, this huge piece of ice broke off from the Larson C ice shelf in Antarctica. The iceberg, named A68, has an area of 5800 km² (2239 miles²).  The authorities say it is the 5th largest berg in history. Because the continent of Antarctica is so inhospitable, it wasn’t till 1821 when an American seal hunter became the first person to actually put foot on this continent. History, in…

    Update on the Larsen-C iceberg breakaway
    August 2, 2017

    While Antarctic ice shelves are in direct contact with both the atmosphere and the surrounding oceans, and thus subject to changes in environmental conditions, they also go through repeated internally-driven cycles of growth and collapse.

    Note: ‘internally-driven’

    I can’t help wondering if it is a requirement for climate scientists to have a blind spot that prevents them seeing anything more than 30 years in the past.

    The blind spot appears be associated with ‘climate’ for some reason and may be the cause of the climate change/global warming stupidity.

  4. The US mainstream media refers to the ‘Delaware-size’ label likely because the far-left in the US (including members of the media) are bi-coastal with the majority on the east coast … and to say the iceberg is the size of California’s San Bernardino County would be a bit hokey. And for not especially informed Europeans who think the US is huge and thus all its states are huge, the ‘Delaware-size’ label still works out well. Basically, our media propagandists are not totally stupid when it comes to effective messaging to the uniformed. It’s one more reason why the media was comparing Larsen C to a cork — let it loose and the whole Antarctic flows into the sea.

    Two things you won’t see: any mainstream media outlining the Larsen C on an Antarctica map that’s superimposed over a map of Australia, or over any other continent map for relative size comparison; or any explanation of how the main polar cap of Antarctica can possibly flow unfettered out of the now-uncorked area of where Larsen C was.

    Ironic how the ‘Green Industrial Complex’, using the mainstream media, claims folks on our side employ deception to push our ‘agenda,’ isn’t it?

    NASA Study: Mass Gains of Antarctic Ice Sheet Greater than Losses
    Antarctic Peninsula

    A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

    The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

    According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.
    . . .
    Zwally’s team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.
