Melting Ice in Antarctica Contributing to Potentially Dangerous Rising Sea Levels

Study: Antarctic ice melting is contributing to rising sea levels
The ice in Antarctica is melting, and it’s doing so changing the sea around it. A recently published study which can be found in the Nature Geoscience Journal has revealed a concerning trend. The rate and level at which the sea is rising in the Antarctic region exceeds the global average by 2 centimeters. The study, which has taken almost 20 years to complete, utilized satellite imagery and the latest in computing technology to run the required simulations.

The researchers, from the University of Southampton, have come to the conclusion that the rapidly rising water levels in Antarctica stem from the massive influx of freshwater into the surrounding oceans. Craig Rye, the study’s lead author, was quoted with saying, “Freshwater is less dense than salt water and so in regions where an excess of freshwater has accumulated we expect a localized rise in sea level.” The authors of this study had also stated, “On the basis of the model simulations, we conclude that this sea-level rise is almost entirely related to steric adjustment, rather than changes in local ocean mass, with a halosteric rise in the upper ocean and thermosteric contributions at depth.” They continued to say, “We conclude that accelerating discharge from the Antarctic Ice Sheet has had a pronounced and widespread impact on the adjacent sub polar seas over the past two decades.”

Essentially, they are saying that the rise is attributed to a chemical reaction, in this case it would be melting ice. Winds pushing warm water under the ice is degrading the ice-sheets in the Antarctic region much faster than what prior researchers had originally thought. This latest study was conducted with collaboration from the British Antarctic Survey and the National Oceanography Center.

With fresh water raising the sea-levels, this can be especially concerning for all coastal mega cities, such as New York or Shanghai, in the distant future. According to another study published in Dec. 2013, by Anders Levermann of the Potsdam Institute for Climate Impact Research, the ice discharge in Antarctica may raise sea levels anywhere from 1 centimeter to 37 centimeters before the end of the century. So there still might be some time to pack up and move inland.

    Your story: Melting Ice in Antarctica Contributing to Potentially Dangerous Rising Sea Levels

    Are you just stupid or what? The Antarctic Ice is at an ALL TIME HIGH and growing (since we began measuring it with satellites more than 30 years ago.

    Where the hell do you get your “facts” ?

    • Kal Kurdi says:

      They’re sourced from educational studies..

    • rick says:

      Salt water is much harder to freeze than freshwater, more ice in winter is due to so much freshwater melt

    • Dr. TOBY says:

      The sea levels worldwide after the pole shift coming soon in the next 1.5 years, will rise 675 ft. within 2 years after the pole shift.

    • Mark says:

      Mike, before calling anyone stupid you should do your research.

      Antarctica is losing land ice at an alarming rate. This ice came from older snowfall and is now being lost (not being replaced) because of climate change.

      The runoff is fresh water. Fresh water freezes more easily than salt. The oceans around Antarctica are less saline and now freeze more easily than they used to so in the winter you get more ice… which melts more easily in the summer.

      Any questions?

      • Brian says:

        Mark you can start by reading real facts not the liberal bull you been reading Mike’s right. Your so called studies have been proven to be falsified to fit the point or view of the parties funding them several times. Several of the scientists from come forward and said they were told if the study didn’t said what they wanted to say that would ensure that they never get funding for any of their research ever again.

        • Chris says:

          I would love to see you source of information on this claim. It is easy to just go around making claims without any evidence. Where is yours?

    • GNB says:

      Can I join you at one of your Tea Parties, where we can discuss “facts”?

    • allworld212 says:

      Oh god. Are you nuts still around?

  • Ross says:

    Sound bites are always bad. You should read about what happens in the summer (record minimums). Fresh water freezes faster so extent can be a fooler.

    “The April Arctic minimum was 270,000sq km higher than the record April low, which occurred in 2007. The Antarctic sea ice extent anomalies were greatest in the eastern Weddell and along a long stretch of coastline south of Australia and the southeastern Indian Ocean. The centre said the increased ice extent in the Weddell Sea region appeared to be associated with a broad area of persistent easterly winds in March and April, and lower-than-average temperatures.”

  • ToddT says:

    Do you have any facts which are not statistical measures produced by rigged computer models?

    There is no way to measure “sea level” in centimeters. That is clearly a statistical average, which can be fabricated to say anything you want. Let me know when you can measure 3 or 4 feet of change, which is a large enough number to really measure.

    And a so called prediction we will have from “1 to 37” centimeters of rise in the next 100 years? Again 1 centimeter, sorry you cant actually measure that number as part of an ocean which never has a flat surface and if all we get is 1 centimeter, who cares. at that rate the sun will go red giant long before sea level rise will be an issue. Not to mention a prediction like this is like saying at least one time in the next 100 years some part of the world might have 4 extra rain drops in a 1000 years.

    Even at 37 cm, still cant really be measured. Statistically you would have to accommodate the ocean waves and tides in every area of the planetary ocean to derive something specific like 37 cm, or about a foot and a half. Again, because of the same tides and waves, storms patterns and ocean currents it is likely a place like the state of main which already has 20 ft tides will get to 21.5 feet and places already with minimal tides might see a centimeter. Basically your so called sea level rise will not be equally distributed as an average on every coastline. It will dramatically affect coast lines already dramatically affected, minimizing impact and other areas will see very little effect at all.

    • JG says:

      What is your background, which allows you to question the 20 years of research the article describes?

    • Dana Stone says:

      So, your argument is: Until the water is four-five feet deeper you won’t believe in changes in the ocean because with waves moving up and down so much, testing averages to the centimeter is impossible.

      Clever usage of head in the sand logic, I like it.

  • Rob Spooner says:

    Melting ice is not a chemical reaction.

  • Terry Remias says:

    Mr. ToddT,

    Your logic is most unacceptable. I advise a college course including Truth Functional Logic as well as learning about what others are trying to say. If you don’t understand, then do something about it like learning.

  • Gary S says:

    For those who may actually want to LEARN something:

    “Greenland and Antarctic ice sheets are losing mass at an accelerating pace . . .”
