seeder Posted January 6, 2017 #1 Share Posted January 6, 2017 Quote ENORMOUS iceberg close to BREAKING AWAY from Antarctica risking FOUR INCH sea rise ONE of the biggest icebergs in the world is on the broke of breaking OFF from Antarctica, after a huge crack appeared. The 5,000 square kilometre block of ice, which is one of the 10 biggest ever icebergs, could spark a four inch rise in sea levels if it rips away. Scientists noticed a large rift in the Larsen C ice shelf in Western Antarctica had expanded suddenly last month. Now they warn it is “hanging on by a thread” and could break away at any moment. While the breakaway of this iceberg will not directly cause sea levels to rise, the experts behind the study from from Project Midas – a UK-based Arctic research group – believe it could leave the entire ice shelf it is attached to vulnerable to crumbling. http://www.express.co.uk/news/science/751040/iceberg-collapse-rising-sea-levels-antarctica 6 Link to comment Share on other sites More sharing options...

But it will rise and will have an effect somehow: If the entire ice shelf does collapse as a result of the departing iceberg, then it could lead to a rise in sea levels of almost four inches. Although four inches does not seem like a huge amount, between 1993 and 2014, the average sea level rose by 2.6 inches meaning that the process of rising waters will be sped up rapidly. http://www.express.co.uk/news/science/751040/iceberg-collapse-rising-sea-levels-antarctica 1 Link to comment Share on other sites More sharing options...

Most will survive, because: The largest truly land animal is a wingless midge about 13mm / 0.5 of an inch long. As the animal life is dependent on the sea and are mainly warm blooded, they tend to be pretty large as a survival technique against the extreme and relentless cold. http://www.coolantarctica.com/Antarctica fact file/antarctica_animal.php land animals can more easily reach the Arctic unlike Antarctica where animals must be able to swim or fly there across hundreds of miles of frigid and storm-prone ocean even at the narrowest point. http://www.coolantarctica.com/Antarctica fact file/arctic_animal.php But the penguins have been hit already: AN iceberg "the size of a small country" has caused 150,000 penguins to starve to death in Antarctica. http://www.express.co.uk/news/nature/644010/penguin-iceberg-colony-killed-die Edited January 6, 2017 by freetoroam 2 Link to comment Share on other sites More sharing options...

Good point and I dont know.....but the article implied with a huge chunk of ice soon to be free....it may encourage further break offs...thus....less ice sheet 2 Link to comment Share on other sites More sharing options...

back to earth Posted January 7, 2017 #12 Share Posted January 7, 2017 Not all of Antarctica has land under it. Higher temps can affect the water under the ice. Maybe there are similar types of dynamics going on there in some areas as there is in the Arctic ; the ice melts from the top, making it weigh less and float higher in the water, this in turn lets more water flow under the ice and more water means more melting, now from beneath, which makes the ice float even higher, and lets even more water through underneath and cause more melting, which makes the ice float even higher ... and so on . and not all of Antarctica is covered in ice either ; 3 Link to comment Share on other sites More sharing options...

It will be claimed as evidence of man-made climate change despite having no evidence other than computer modeling (give someone enough time they can create a computer model that will show anything they want including that unicorn farts caused something to happen) and "educated" guesses. 1 Link to comment Share on other sites More sharing options...

Frank Merton Posted January 9, 2017 #20 Share Posted January 9, 2017 This is all sea ice, so, even if it melts in the end, it will not serve to raise sea level (actually lower it a tad since ice floats and hence displaces water). However, it tells us a message -- the sea ice will go first, and is now going. The land ice is getting thinner, melting both top and bottom. We are being warned over and over, but some politicians and businessmen, with their own agendas, ignore the warnings. 2 Link to comment Share on other sites More sharing options...

We all ignore the warnings. I probably could have found a ride to work instead of driving my car. We all buy and use products with Chinese made parts. We know that factories in China pollute more than factories in most other countries. 2 Link to comment Share on other sites More sharing options...
Barkinghorse Posted January 9, 2017 #22 Share Posted January 9, 2017 As huge ships displace tons and tons of water with their drafts, I wonder if pulling all ships out of the water would lower the sea levels 2 Link to comment Share on other sites More sharing options...

I don't have all the figures needed of course so let's make a swag. There are currently about 5100 cargo vessels globally with a combined capacity of about 18 billion tons of displacement. Let's add another 1-2 billion tons for cruise ships and domestic vessels. Another 2 billion for military. Round up to 22 billion tons. The Larsen shelf is losing between 24-40 billion tons of fresh water a year, and year-over-year sea level rise is a fraction of an inch... so best guess of the effect of removing every ship from the ocean on sea levels: very little, but not zero.

That would be a logical fallacy and I know you can think better than that. Link to comment Share on other sites More sharing options...
