    Recently unearthed photographs taken by Danish explorers in the 1930s show glaciers in Greenland retreating faster than they are today, according to researchers.
    1930s photos show Greenland glaciers retreating faster than today ? The Register

    OK AlGore and all you chicken littles.. please explain!!!

    Maybe that's why James Lovelock has retracted his alarmist views on global warming. Noted author of the Gaia hypothesis garnered attention in 1979 with his views on the globe as a self-managing system. He now recants his position that the world is headed for catastrophic change in climate. According to an MSNBC report, Lovelock admitted, “all right, I made a mistake.” He admits that global warming is not happening as he expected. What did he expect? Along with other alarmists like Al Gore, Lovelock expected rising temperatures to force folks to live in the Arctic, the only place on earth for tolerable temperatures.

    AGAIN... I really would like AlGore et.al. "Glaciers are melting so fast that the coasts of Florida and other water fronts will be under water before 2040" ..
    explain how even with the glaciers melting that add annually the equivalent of .000056% of all the water in all the oceans!

    There are 343 quintillion gallons of water in all the oceans.
    How many gallons of water does the ocean have

    The addition of 385 billion tons of water by melting glaciers would add
    OK... the equivalent of .000056% of all the water in all the oceans!

    This is the same as 23 ounces of water in an 648,000 gallons of an Olympic pool!

    Hey stupid !

    This article compares melting to 10 years ago.

    The OP is comparing to 80 years ago.

    Wow......you just don't get it. You've got the Kool-Aid needle stuck so far up your arm you can't bend your elbow. Pay attention and digest the difference.

    Or is that possible for you ?

    It is always wise to look at the big picture. Gore seems more interested in making billions and redistributing our wealth through cap and trade policies than global warming. If he and his ilk were concerned, they'd be walking the walk. They wouldn't jet around and own several large mansions. They make a huge footprint compared to most and yet they want us to believe they are concerned.

    I look at what they do, not what they say.

    Nature Geoscience 5,37–41(2012)doi:10.1038/ngeo1349Received 21 June 2011 Accepted 14 November 2011 Published online 11 December 2011

    During the early 2000s the Greenland Ice Sheet experienced the largest ice-mass loss of the instrumental record1, largely as a result of the acceleration, thinning and retreat of large outlet glaciers in West and southeast Greenland2, 3, 4, 5. The quasi-simultaneous change in the glaciers suggests a common climate forcing. Increasing air6 and ocean7, 8 temperatures have been indicated as potential triggers. Here, we present a record of calving activity of Helheim Glacier, East Greenland, that extends back to about AD 1890, based on an analysis of sedimentary deposits from Sermilik Fjord, where Helheim Glacier terminates. Specifically, we use the annual deposition of sand grains as a proxy for iceberg discharge. Our record reveals large fluctuations in calving rates, but the present high rate was reproduced only in the 1930s. A comparison with climate indices indicates that high calving activity coincides with a relatively strong influence of Atlantic water and a lower influence of polar water on the shelf off Greenland, as well as with warm summers and the negative phase of the North Atlantic Oscillation. Our analysis provides evidence that Helheim Glacier responds to short-term fluctuations of large-scale oceanic and atmospheric conditions, on timescales of 3–10 years.

    Glaciers expand and contract naturally. Everything from the wobble of the earths axis to solar activity and geological activity effects the rate.

    All else is just human speculation.

    So, let's look at the whole article by the scientists.


    Analyzing the images, the researchers found two events that stood out most over the past 80 years: glacial retreats in 1933-34 and from 2000 to 2010. In the 30s, fewer glaciers were melting than are today, and most of those that were melting were land-terminating glaciers, meaning they had no contact with the sea.
    But those that were melting were retreating at the average rate of 65 feet per year and up to 1,225 feet per year. More than 50 percent of the glaciers in the study had similar or higher retreat rates in the 30s than they do today.

    While melting rates are not occurring as fast as they were in the 30s, more glaciers are retreating today. And, while the average ice loss is around 150 feet per year, that is because a few glaciers have very fast melting rates, driving the average up.

    Widespread retreat of glaciers has been observed along the southeastern margin of Greenland. This retreat has been associated with increased air and ocean temperatures. However, most observations are from the satellite era; presatellite observations of Greenlandic glaciers are rare. Here we present a unique record that documents the frontal positions for 132 southeast Greenlandic glaciers from rediscovered historical aerial imagery beginning in the early 1930s. We combine the historical aerial images with both early and modern satellite imagery to extract frontal variations of marine- and land-terminating outlet glaciers, as well as local glaciers and ice caps, over the past 80 years. The images reveal a regional response to external forcing regardless of glacier type, terminal environment and size. Furthermore, the recent retreat was matched in its vigour during a period of warming in the 1930s with comparable increases in air temperature. We show that many land-terminating glaciers underwent a more rapid retreat in the 1930s than in the 2000s, whereas marine-terminating glaciers retreated more rapidly during the recent warming.

    Well Lovelock is wrong! He should have stuck with his original statement.

    And you should watch this....

    [ame=http://www.youtube.com/watch?v=jqxENMKaeCU&feature=watch-now-button&wide=1]HOME - YouTube[/ame]

    If you don't have the patience to sit for 90 minutes or so and hear things that rock your beliefs you can catch good VIDEO and hear SCIENTIFIC evidence of the catastrophe looming in the arctic at 1:01:15 in this video.

    Give the whole thing a view though if you can. You could learn a lot.
