Antarctica sea levels rising faster because of fresh water from melting glaciers, say researchers
Sea levels around Antarctica are rising faster than anywhere else in the southern ocean. The global average rise in ocean heights in the last 19 years has been 6cms, but the rise in seas around Antarctica is 2cms higher. Read full article

Disclaimer & comment rulesBut I thought the massive earthquake in Chile in 2010 created shock waves and warm water in the Antarctic to augment the already warm currents coming up under the ice and melting it?

Anyway, didn't the doomsayers from 'Global Warming', cross that out, 'Climate change' cross that out, 'The pause effect (world getting colder) will last ten years and then the rise will come back' [not as catchy is it?] predicted 200 miles rise in sea levels, or have I exaggerated it by the same amount as they lie?
Remember when Monsanto destroyed the pampa and soros moved in to frack and ruin the water supply?

Sep 09th, 2014 - 06:34 pm - Link - Report abuse 0we suggest freezing Argentina...lol
So does the fresh water lie on top of the salt water and give an increased height...?
Sep 09th, 2014 - 07:38 pm - Link - Report abuse 0Why doesn't it spread out...and keep spreading until it gives negligible increase in level...?

Sep 09th, 2014 - 10:32 pm - Link - Report abuse 0If you try to dissolve even fine salt granules in fresh, cold, water it will take an inordinate time, so yes, the fresh water floats on top of the brine (seawater which is supersaturated with salt).
And yes, eventually the fresh water becomes brine and the rise is negated.
Trying the same thing in hot water is virtually impossible because salt is almost impervious to hot water.
I would imagine they arrived at the figure by calculation: the volume of fresh ice (LxDxT of the calf) and the time it takes to be absorbed once liquid results in the thickness (the water area is a function time versus volume and the thickness a function of area versus volume).

Sep 10th, 2014 - 06:05 am - Link - Report abuse 0Tell that to Yankeeboy. He swears that fracking does no damage to the water supply of the acquifer that is the backbone of US agriculture in the entire central region of that country.
And soroes “moved” in? There is no fracking in Argentina, and won't be for a while. We take care of our treasures by not digging them out, and protect our environment.
Anyway, the rise in temperature in this region of Argentina is concerning. We should do more to mitigate the effects of warming in Antarctica, before it spreads to the rest of the country.
