Iceberg the Size of Delaware, Among Biggest Ever Recorded, Snaps Off Antarctica (marketwatch.com) 305

A giant iceberg about the size of Delaware that had been under scientists' watch has broken off from an ice shelf on the Antarctica Peninsula and is now adrift in the Weddell Sea. From a report: The 2,200 square-mile, trillion metric-ton section of the Larsen C ice shelf "calved" off sometime between Monday and Wednesday, a team of researchers at Swansea University's Project MIDAS has reported, citing imaging from NASA's Aqua MODIS satellite instrument. Scientists have tracked the crack for more than a decade and they warned in June that the section was "hanging by a thread." Its break, from Antarctica's fourth-largest ice shelf, changes the border shape of the peninsula forever even though the remaining ice shelf will continue to grow. "The iceberg is one of the largest recorded and its future progress is difficult to predict," said professor Adrian Luckman of Swansea University, lead investigator of the MIDAS project. "It may remain in one piece but is more likely to break into fragments. Some of the ice may remain in the area for decades, while parts of the iceberg may drift north into warmer waters."

    To build a new, unsinkable, super cruise liner ship. At least four chimneys will be required.

    they've always wanted one.
    • they've always wanted one.

      There is an awful lot of water in that iceburg. That could make a big impact on their water needs. (or any other country that were able to harvest it).

  • Nothing to see here folks.. Move along. Don't pay any attention to weeds and bugs that are moving north... Move along. Just another stupid ice thing broke in some god forsaken land. Just pay not attention.

    Hey look! The latest outrageous tweet. Keep chasing that like a dog chases the laser pointer dot.

      "Nothing to see here folks.. Move along."

      Actually in this case, its more emblematic than anything. From the BBC article:

      "What is the significance of the calving?

      In and of itself, probably very little. The Larsen C shelf is a mass of floating ice formed by glaciers that have flowed down off the eastern side of the Antarctic Peninsula into the ocean. On entering the water, their buoyant fronts lift up and join together to make a single protrusion.

      The calving of bergs at the forward edge of the shelf is a very natural behaviour. The shelf likes to maintain an equilibrium and the ejection of bergs is one way it balances the accumulation of mass from snowfall and the input of more ice from the feeding glaciers on land. ...

      But Larsen C today does not look like its siblings. Prof Helen Fricker, from the Scripps Institution of Oceanography, told BBC News: "The signs we saw at Larsen A and B - we're not seeing yet. The thinning we saw for Larsen A and B - we're not seeing. And we're not seeing any evidence for large volumes of surface meltwater on the order of what you would need to hydro-fracture the ice shelf.

      "Most glaciologists are not particularly alarmed by what's going on at Larsen C, yet. It's business as usual.""

      Obviously its great to have massive events like this to draw attention to the cause, and keep climate change at the front of peoples minds, but it seems like this isnt that big a deal. It isnt raising sea levels or single handidly causing giant problems by its calving alone.

      Just part of the program these days.

    Why use Delaware? It's less taxing [google.com] than other states!

  • "The 2,200 square-mile trillion metric-ton section".

    Please post these things in units that can be universally understood.

    How big is it in football fields?
    • How many Olympic-sized swimming pools would it fill?
    • Please post these things in units that can be universally understood.

      They did.

      For the imperialists, "2200 square mile" is a relevant unit.

      For everyone else, "trillion metric-ton" is relevant. A metric ton is 1000 kg. At about 1kg per 1000 cc, that's 1e6 cc. A trillion (1e12) of those would be 1e18 cubic centimeters. About. Every metric user should immediately identify that kind of volume.

      The only problem in combining the imperial with metric is that one is a volume and the other is an area. But let's play. 2200 square miles is about 5.7e9 square meters, if my math is rig

  • For all those people wondering what we're comparing the iceberg to. Apparently it's bigger than:

    Madrid: 604km^2
    London: 1572km^2
    Luxembourg: 2586km^2
    Twice the size of the Australian Capitol Territory: 4716km^2
    *
    Delaware: 6452km^2
    Four times** the size of the Australian Capitol Territory: 9432km^2

    * Size of iceberg actually slots in here.
    ** The twice the size and four times the size were both in the same article [news.com.au].

    Its break, from Antarctica's fourth-largest ice shelf, changes the border shape of the peninsula forever even though the remaining ice shelf will continue to grow.

    It is the use of words like this that make me wonder about the sanity of the people writing this shit.

    The headline should be: Unfathomably large chunk of ice just broke off of an ice shelf in Antarctica.

    Why would anyone care if the fucking coastline has changed? Forever. The universe is not a static place, coasts even less static than most. Why is the coastline changing forever even a part of this story?

    I am sure such insanity is being promulgated for a reason. I have no idea if it is to drive me away from, or to, whatever mouthbreathing thing they are trying to push but I am weary of it.

    Just provide facts. A VERY light touch of speculation of what it could mean is okay as long the writer specifically mentions it is speculation. It is almost as if we can't think for ourselves or something... or actively being prevented from thinking?

  • Double it and add thirty. So that's thirty-two metric Delawares.

    At the end of the video we get "It was a natural event that had been anticipated for months and was not directly caused by climate change."

    Putting this 'insignificant' piece of information at the end speaks volumes as to why people are tuning out MSM.
