peer-reviewed study showing Northern Greenland ice melt is largely caused by mantle heat adds to the growing mountain of evidence showing how geologic forces influence our climate, and not from the trace gas carbon dioxide. Two and a half years ago, Plate Climatology Theory (PCT) was introduced, extolling that geological forces are a major driver of Earth’s climate and climate-related events, including the bottom-up (basal) melting of major ice sheets by geothermal heat flow. This new study also gives PCT even more momentum toward acceptance by mainstream scientists. At the very least, time and research should be allocated to studying PCT by the scientific community.The release of yet another
This latest study by the German Research Centre for Geosciences (GFZ) concluded that geothermal heat from an ancient and active hot spot—which lies beneath a significant portion of northern Greenland—is the primary cause for the ice sheet melting. And not atmospheric warming. This specific research not only fits well with the basic tenets of PCT, it also adds credence to a previous December 2014 CCD article, “Greenland Ice Melt Geothermal, Not Manmade.”
The new GFZ study builds on facts we already know: that Greenland lies along and is directly involved with one of the largest fault / rift zones on the planet, called the Mid-Atlantic / Mid-Arctic Rift System (see image above). This 14,000-mile-long fault zone is an upper crustal plate boundary extending from Antarctica to Russia. Along the way it and its branches pass beneath both polar ice caps and the entire length of the Atlantic Ocean.
The rift is actively pushing the continents apart, such as North America and Africa, at an astounding 2.5 centimeters per year (that’s about how fast a fingernail grows). Its awesome power is on visual display nearly every year as massive pulses of super-heated and chemically charged ash from volcanic eruptions on Iceland, which straddles the Rift.
Unseen by humans, largely because the deep ocean and the base of our polar ice sheets are almost entirely unmonitored, are other numerous and massive pulses of super-heated / chemically charged fluid from the rift. These deep ocean and sub-polar ice sheet pulses from the Mid-Atlantic / Mid Arctic Rift System are responsible for many natural changes in our climate and climate-related events as previously discussed in other Climate Change Dispatch articles: Arctic Sea Ice melting (see here), sub-glacial melting of selective Antarctic glaciers (see here), altering of the Gulf Stream Current (see here), and sub-glacial melting of selective Svalbard Island glaciers (see here).
Many “natural” changes in the climate and climate-related events are not properly explained by atmospheric forces, and are done at the expense of obvious geologically induced influences. It’s long overdue to change this narrowly focused narrative in explaining how our climate works. Climate science has been hijacked by a few at the expense of the many, and until more people start calling out these agitprop climateers, the status quo will continue.
James Edward Kamis is a Geologist and AAPG member of 42 years with a B.S. and M.S. in geology who has always been fascinated by the connection between Geology and Climate. More than 10 years of research / observation have convinced him that the Earth’s Heat Flow Engine, which drives the outer crustal plates, is also an important driver of the Earth’s climate. The Plate Climatology Theory was recently presented at the annual 2016 American Metrological Society Conference in New Orleans, LA, (see conference poster (PDF)).
