GREENLAND Part 2 of 6

Greenland Size: On most maps that we run across and use, Greenland is beyond extremely exaggerated as much larger than its physically size is by use of what is called the Mercator style of map. The Mercator style map attempts to create a flat map of the Earth resulting in exponential stretching starting at the equator reaching out to north and south poles. In the middle of a Mercator map from left to right at the equator equals 24,901 miles, while at the North or South Pole, from left to right on the top or bottom of the map equals an inch or less, that being a great stretch on the map from what is reality. Then, in order to make the land look proportionally correct, vertical stretching is applied making Greenland taller along with wider. Turning a three dimensional sphere into a flat map and maintaining accuracy is impossible. Therefore, we are stuck with using deceptive maps. The United States is 4.6 times bigger than Greenland and Africa is 14.1 times bigger than Greenland. Greenland is at its widest east to west around 1,300km (800 miles) and height from north to south around 2,670km (1660 miles). Therefore, Greenland is not small in human sense but small in the overall scope of the Earth's size.

To most, the perception of Greenland is it is much bigger than it really is.

Greenland Shape and Terrain: Greenland is overall a basin, shaped roughly like a bowl with the outer edge being mostly hills and mountains that land locks the lower altitude ice from glacial flow. The eastern and southern parts of Greenland are made up mostly of mountain ranges, while the north and west have some mountains, the altitude of the land otherwise varies from near sea level to around 1,500 meters. The large portion of the center of Greenland is 50 meters to below sea level in altitude. This is important to know when it comes to examining how glaciers flow on Greenland from the forces caused by gravity. The highest point is not the ice sheet but many mountains that include Mt. Gunnbjorn at 3,700 meters (12,139 ft), while the ice sheet highest elevation is around 3,200 meters. Greenland’s low center surrounded by high terrain is a serious obstacle to glacier flow. Across the northern hemisphere are many land masses but none have ice accumulation like Greenland, this is because of its shape, size, and surroundings, Greenland by design will retain its ice mass for a very long time, even if the temperature were to increase by 30C (54F) to 40C (72F) it would take thousands of years to loss half the ice!

Greenland is a basin preventing any serious loss of ice by glaciers.

Greenland's Ice Sheet: The Greenland Ice sheet is massive. Its length‎ is ‎2,400 km (1,500 mi), width‎ at the widest point is ‎1,100 km (680 mi), thickness‎ is ‎ 100  to 3,200 meters (~10,600 ft), and area‎ is ‎1,710,000 km2 (660,000 sq mi). The amount of ice on Greenland is 684,000 cubic miles and weighs 2,882,102,400,000,000 tons (2.88 Petatons). At first thought when hearing that the ice sheet on Greenland is melting is to find evidence that it is or is not. One would need a few decades of time and tens of millions of dollars to self analyze Greenland to validate whether the ice sheet is gaining or losing concerning mass. This is impossible for any individual. HOWEVER, there are proofs that Greenland ice sheet has been gaining accumulation and expanding. One book over 100 years ago showed a mapping of Greenland and the extent of the ice sheet at that time, the book by Albert Perry Brigham & Charles T. McFarlane, Essentials of Geography (New York, NY: American Book Company, 1916). When comparing NSIDC / NASA image of the Greenland ice sheet from 2016, there is no question that the ice sheet is considered now to cover a much larger area than 100 years ago. There are various objects giving clue to the massive accumulation, such as Glacier Girl, a plane that crashed in 1942 and recovered 50 years later. This plane was buried in the packed snow and ice 82 meters (268ft) deep in 50 years time. Other indicators of accumulation on Greenland were the DYE-2 and DYE-3 radar stations, these over 50 meter high radar stations were designed to be periodically raised above the constant accumulation on Greenland. DYE-2 was active from 1959 to 1989 was raised 32 meters while active and now has 22 meters of accumulation around it, for a total of 54 meters (177 feet) since 1959. DYE-3 active from 1959 to 1991 was raised 41 meters while active and now has 35 meters of accumulation around it, for a total of 76 meters (250 feet) since 1959; soon it will disappear under the accumulation. Another factor is that it snows almost daily on Greenland making the melt story not only difficult but also impossible. Concerning melting loss of the Ice Sheet, the Danish Meteorological Institute (DMI), reports on this daily with the average annual accumulation to include loss from melting for a gain of over 350 Gigatons per year. Therefore melting of the Greenland ice sheet is not a concern failing to keep pace with the accumulation. The real loss is supposed to come from glaciers but that must be questioned whether it is a concerning loss. Why is DMI important to the reporting of the status of the Greenland Ice Sheet? DMI is a government entity for Denmark, and Greenland is a territory of Denmark. https://www.dmi.dk/en/about/

Greenland accumulation by snow, rain (turns to ice), and condensation, is greater than its loss to melt, evaporation, and water runoff.

How much ice mass is on Greenland? This is a hard number to find in mass or weight (w=mg) but can be easily calculated from the numbers that are available. There are 684,000 cubic miles of ice on Greenland, there are 4,600,000,000 tons in a cubic mile of water, with water as 1 for density, the ice sheet has a density at a tenth less at 0.916, so the ice sheet on Greenland is 684,000 x 4,600,000,000 x 0.916 = 2,882,102,400,000,000 tons (2.88 Petatons or 2,880 Teratons or 2,880,000 Gigatons). The reason it is important to express it in Gigatons is the claimed loss by DMI is around 200 Gigatons per year, sounds big until one compares it to the total of 2,880,000 Gigatons. At 200 Gigatons per year, it would take 14,000 years for Greenland to lose all its ice and in 200 years at that rate would only equate to add one tenth of a meter (0.33 feet (4 inches)) to sea level rise, NOT MUCH. Problem for the fear mongering scientist is that the last two years of 2016-2017 and 2017- 2018, Greenland IAW DMI has had a net gain rather than the supposed average loss of 200 Gigaton. Where is this Climate Change? Where is the accelerating loss of Greenland ice from 120 years of industrial age and increased carbon dioxide? Are you starting to feel something is not right?

The Greenland Ice Sheet has a mass of 2.88 Petatons.
