Animation: Ice Mass Loss on Greenland, 2003-2011

Greenlands glacier retreat was greater in the 1930's than it is today. But that would be science and you cultists don't do science. Do you....

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


We're not worried about rising sea levels. Well, we are in a seaplane.

The photos in question were taken by the seventh Thule Expedition to Greenland led by Dr Knud Rasmussen in 1932. The explorers were equipped with a seaplane, which they used to take aerial snaps of glaciers along the Arctic island's coasts.

After the expedition returned the photographs were used to make maps and charts of the area, then placed in archives in Denmark where they lay forgotten for decades. Then, in recent years, international researchers trying to find information on the history of the Greenland glaciers stumbled across them.

Taken together the pictures show clearly that glaciers in the region were melting even faster in the 1930s than they are today, according to Professor Jason Box, who works at the Byrd Polar Research Center at Ohio State uni."

Horse crap. They never bothered to measure it before so we have no idea WHAT it was like before. And as I pointed out in the other link, carbonates are MORE SOLUABLE in colder water than warm which kinda screws with your little fairytale....


"Counter to the typical increase of mineral solubility with increasing temperature observed for most minerals, many carbonate minerals are more soluble in cold water. For example, the Ksp for calcite at 0 and at 50 is 10-8.02 and 10-8.63, respectively (Garrels and Christ, 1965). These values represent about a four-fold difference in calcite solubility caused by temperature alone. A thorough discussion of the thermodynamic reactions of carbonate minerals solubilities is beyond the scope of this article. A simplified explanation for carbonate minerals being more soluble in cold water is that the dissolution reaction for carbonate minerals is exothermic, which results in higher temperatures favoring the solid phase over dissolved ions. A more detailed discussion for this unusual behavior can be found in Langmuir (1997).



In addition to an increase in solubility products with decreasing temperature, carbon dioxide is more soluble at lower temperatures, further favoring carbonate mineral dissolution in cooler environments. More carbonic acid is present in cold water at a given partial pressure of carbon dioxide (P ) and carbonic acid concentration is the controlling factor for the solubility of carbonate minerals under natural conditions. Carbon dioxide is obtained from the air or from decomposition of organic matter that releases carbon dioxide which reacts with water to form carbonic acid. These factors combine to form the calcite compensation depth (about 4,500 m) below which calcite dissolves.



When geothermal waters reach the surface of Earth and precipitate tufa, a calciumcarbonate rock, some reaction must overcome the temperature decrease or these waters would dissolve calcite rather than deposit tufa as the water cools. The required reaction is the loss of CO2 due to lower P pressure at Earth’s surface and subsequent a decrease in the amount of carbonic acid, which controls the amount of dissolved calcite (see Calcite Solubility below)."
