And so it begins: the ordained and predictable global warming hype has shifted into high gear in preparation for the United Nations Climate Change Summit (Paris, Nov. 30-Dec. 11, 2015). As this fervent process ramps up over the next five months, advocates of the man-made global warming theory hope to accomplish the following: flood the media with supposedly consensus, pro-global warming scientific studies, lay the groundwork for a world carbon tax, and most importantly, engage global warming skeptics in a monumental climate science war.
The first battle in this climate science war concerns the cause of accelerated melting and partial collapse of Antarctica’s Larsen B Ice Shelf. Predictably, global warming advocates claim that humans are to blame citing a recent research study by the National Aeronautics and Space Administration (NASA).
Here we show that this claim and the NASA research study are incorrect and some might say misleading because they do not take into account all of the relevant information, much of it geological in nature. A list of geological information that is directly or indirectly related to the cause of Larsen B Ice Shelf melting / collapse, and not mentioned in the NASA report is as follows:
- The Larsen B Glacial area is adjacent to, and on geological trend with five active sub-ocean volcanoes (Figure 1)
- Sub-Glacial heat flow is the probable cause of basal melting of the Thwaites Glacier in the Marie Byrd Land area (Figure 1) (West Antarctic Ice Sheet Melting From Geothermal Heat, Not Global Warming).
- Mount Erebus, a 12,448 foot high land volcano located in the McMurdo Volcanic Group area, has become more active (Figure 1) (Evidence Shows Geothermal Activity Linked to West Antarctic Ice Melt). The distinctive glow of its summit lava crater is visible on NASA satellite images.
- A group of eight sub-ocean volcanoes far north of the Larsen B area have recently been identified and found to be active (Figure 1).
- The Larsen B Ice Shelf lies atop a major fault system, the giant and active 3,000 long West Antarctica Rift (Figure 1).
- Recent research and actual drilling through the thick ice sheet has led to the discovery of numerous sub-glacial hot springs, most located along the West Antarctic Rift System. These sub-glacial hot springs have created a huge interconnected network of sub-glacial freshwater streams and lakes (Evidence Shows Geothermal Activity Linked to West Antarctic Ice Melt)..
- In Greenland, the sudden and unexpected basal melting of a few selective glaciers has recently been associated with geological fault induced geothermal heat flow. (Greenland Ice Melt Geothermal, Not Manmade).
- The 2001-2007 accelerated basal melting of the Arctic Ice Sheet has been shown to be related to a series of deep ocean volcanic eruptions associated with the giant Gakkel Rift fault system (Update on Geothermal Heat and Arctic Ocean Sea Ice Melt).
- Increased basal melting of the Austfonna Glacier on the Svalbard islands located north of Iceland has been shown to be associated with basal geothermal heat flow (Fire and Ice).
- Overall the Antarctic ice sheet has grown in size for 35 years, except in a few selective areas which are related to geologically induced geothermal heating. An overwhelming number of these selective glacial melting areas are associated with the West Antarctic Rift System.
The above geological information clearly shows that the Larsen B Ice Shelf is located along an active geological system known as the West Antarctic Rift System. NASA’s failure to at least mention this fact and the probable influence of associated geothermal heat flow concerning the sudden changes in the Larsen B Ice Shelf is truly remarkable.
This is especially surprising considering that NASA has sponsored, and in some cases been directly involved in, research studies which confirm the existence of significant present day Antarctic geothermal heat flow.
Put simply, the planet has not warmed for 18.5 years, the Antarctic ice sheet has grown for the last 35 years, only selective Antarctic glaciers atop known active geological systems have melted, the Arctic ice sheet melt of 2001-2007 was related to deep ocean volcanic eruptions, and NASA has failed to mention the proven existence of Antarctica geothermal heat flow.
