New Study of Glacier Melting

Postby KeithE » Fri Aug 22, 2014 9:10 pm

From the European Space Agency’s Cryostat satellite:
Greenland losing 375 cukm/year

Not a traditional “graph", William, but data nonetheless.

Antarctica losing 160 billion tonnes/year.

Total loss is 500 cukm/year.

"The contribution of both ice sheets together to sea level rise has doubled since 2009," said Angelika Humbert from Germany's Alfred Wegener Institute.

"To us, that's an incredible number," she told BBC News.

Those of us who live in the upper Midwest may be living in the place to be for people to flee rising coastal waters, and higher temps and drought in the south.

    Keith, you swallow hook, line, and, sinker nearly every hysterical AGW scaremongering headline to come down the pike. :lol: The article to which you posted the link is old news (old propaganda). It was published last May. Glaciers, not only in Antarctica, but all over the globe, have been advancing and retreating since records have been kept. Earlier this year, a paper was released that finds glaciers have been melting naturally at the same rate since 1850 with no acceleration predicted.

    Melting glaciers in West Antarctica and the Antarctic Peninsula are completely meaningless in the scheme of things. The fact of the matter is that Antarctica has been setting records sea ice extent for
    233 consecutive days. Just yesterday, that fact was posted on the Sunshine Hours website (nice graph included as documentation). Back in April, Antarctic sea ice coverage reached record levels, hitting 3.5 million square miles — the largest on record. Sea ice coverage was growing about 43,500 square miles a day, according to the National Snow and Ice Data Center (NSDC). April 2014 beats the previous sea-ice coverage record from April 2008 by a whopping 124,000 square miles. (Source...) So you want to get hysterical about a measly 160 billion tons of melting ice from Antarctic glaciers. Consider how much sea ice was being added every single day in April (43,500 square miles). I haven't done the math, but it would most certainly exceed a measly 160 billion tons...

    I'll not elaborate any further on the the record setting sea ice extent in Antarctica, but will simply post links to articles that pretty much debunk the notion that melting glaciers are somehow "proof" that AGW is wreaking havoc on Antarctica. The first one was posted yesterday that shows Antarctic sea ice has been above average for 1000 straight days Other articles are:Melting glaciers, whether they be in Antarctica, Greenland, Alaska, or wherever are meaningless insofar as proving AGW. There is no documentation whatsoever that can prove that human activity is the prime cause of melting glaciers. Such a notion is mere propaganda...

David, as I have explained numerous times, the sea ice around Antarctica is slightly increasing due to the melting of the continental Antarctica glaciers and some of that refreezes on the sea ice shelf. The article I’m talking about concerns the loss in glacier volume/weight and far greater volume than the sea ice shelf.

Overall there is a sea level rise due to this Antarctic melting and melting throughout the world that reputable scientists attribute to man’s activity.

It is true that the sea level rise rate is not very great at this time (about 1.4 Inches/decade) but it is confirmed by tidal gauge records since 1870 and independent satellite altimetry measurements since 1993.

As for projections, here is a good summary of 90 expert projections.
In the long run, sea-level rise will be one of the most serious consequences of global warming. But how fast will sea levels rise? Model simulations are still associated with considerable uncertainty – too complex and varied are the processes that contribute to the increase. A just-published (Nov 2013) survey of 90 sea-level experts from 18 countries now reveals what amount of sea-level rise the wider expert community expects. With successful, strong mitigation measures (red below), the experts expect a likely rise of 40-60 cm in this century and 60-100 cm by the year 2300. With unmitigated warming (purple below) , however, the likely range is 70-120 cm by 2100 and two to three meters by the year 2300.

Underlines mine.
