A chunk of ice 20 times bigger than Manhattan has broken off the Brunt Ice Shelf in Antarctica. Scientists from the British Antarctic Survey first detected cracks in the shelf ten years ago.» Subscribe to NBC News: http://nbcnews.to/SubscribeToNBC

  1. A76 is 4,320 km^2 or 0.03% of the total ICE CAP.

    Pine Island glacier contains 180,000 Gt of ice or 0.73% of the entire ICE CAP.

    Ooooohhhhh, SCARY!!!!!!

    Antarctica covers 14.2 E6 km^2 (NBS equivalents: 20 * Texas, 2,768 * Delaware or 163,218 * Manhattan) with an average ICE CAP thickness of 1.9 km for a volume of 2.698 E7 km^3.

    Ice has a density of 9.2 E11kg/km^3.

    The Antarctic ICE CAP (NOT sea ice!) contains 2.482 E19 kg of ice, 2.482 E16 tonne, 24.82 E6 Gt.

    Between 2002 and 2012 the Antarctic ICE CAP supposedly “lost” about 1,200 Gt or a decrease of 0.0048%, 48 ppm, per decade.

    At that rate the ICE CAP will be all gone in 206,850 years.

    I don’t plan on waiting around.

    You?

    Every year the SEA ICE swings from around 3E6 km^2 during summer to 14E6 km^2 (doubling the polar coverage) during winter.

    Thwaites glacier is 192,000 km^2 or about 1.3% of the ice cap.

    Yawn!!!!!

  2. So many intelligent people here for war want to show how powerful they are with their arms,nuclear weapons ..do they care about it do they plant a tree for save world do they have any humanity so this type of news its just a news its wont work for well-being of earth

  3. My question is, why do scientist seem to be intimidated

    The Antarctic will hit the tipping point between now and 2025 IMO.

    Why sugarcoat it or be conservative?

    The world should at least know what the worst-case scenario looks like
    .
    The soft tectonic plates of the antarctic are especially vulnerable to the massive shifts in weight from the trillions of tons of weight of the ice shelves currently anchored on the ground.

    When that weight is 'suddenly' released we will see an acceleration of ice melt that will make the last 20 years' worth of acceleration seem ridiculously small.

    Volcanic fissures, eruptions, earthquakes and tsunamis.

    What would a huge tsunami do the Antarctic ice shelf???

    Please put together a 'complete' worst-case scenario so we can prepare if it indeed happens

  4. Imagine they detected the crack 10 years ago… 10years now is so very fast, we expect more more natural climate change after 10years. Actually climate changes everyday all over the world

  5. repent and turn to jesus christ while you still can, or you know sit around and mess around while you watch the world burn and flood.

  6. People say this is the size of Hobart, but the other says the size of Brisbane. Brisbane is way bigger, that’s really concerning.

  7. John 3:16 “For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.”

  8. 2014 had the greatest ice coverage in recorded history. The only reason we're having a huge iceberg break loose is that winters have so much ice! Ah, they forgot to mention that.

  9. there was literally no point to that. could’ve just stayed together instead of being so dramatic 🙄🙄
