CCD Editor's Note: Megaplumes, especially very large ones, have an underappreciated affect on climate and climate-related events, according to James Kamis, a geologist who has been working in the field for over 40 years. Below he describes how megaplumes, a powerful geologic force, have been relegated to the back burner in the ongoing climate change debate. * * * * * Megaplumes are massive three-dimensional cells of seawater that exhibit elevated heat and chemicals properties. They are generated by the sudden expulsion of super-heated and chemically charged seawater from geographically extensive and volcanically active deep-ocean regions such as major tectonic plate boundaries or upper mantle hotspots (Figure 1). The affected ocean region exhibits increased temperatures, altered chemical composition, modified currents, and increased turbulence, all of which act to vertically mix portions of the water column.https://climatechangedispatch.com/wp-content/uploads/images_pics7_vent_white_smokers.jpg
