Apocalyptic Scenario 7.b

Surrounding the Arctic Ocean, the continental shelf harbors thousands of gigatons of of methane in the form of methane hydrate, fire-ice. This substance, methane gas surrounded by water ice, forms when microbes eat organic sediment and release methane (like in the bowels of a bovine) which gets trapped by high water pressure and low temperature.

Were just five of these gigatons of methane to be released into the atmosphere the concentration would double methane’s current contribution of 25% of global warming.

Fifty gigatons would wreak an environmental catastrophe. Five hundred, released in a continuous stream around the Arctic would induce another PETM (Paleocene-Eocene Thermal Maximum).

Deep beneath the East Siberian Sea stretching across the straight into the Beaufort Sea and around to the Barents Sea the earth is shifting. Tectonic forces have been pulling apart the crust, magma is seeping upward, and now the once frozen methane hydrates are thawing. Swelling. Bubbling to the surface.

Vents along the Siberian coast crack open and haphazard lightening strikes have ignited the plumes of methane. Volcanoes of flame burn hundreds of meters into the sky. What doesn’t burn, drifts high into the atmosphere where it traps the reflective solar energy. The Arctic has become a tepid bath. Greenland’s ice cap and its hundreds of glaciers steam and melt. Measurements along the Eastern Seaboard measure an inch a month sea level rise.

Life is about to experience Sauna Earth.

Bring your beer and spruce brushes because we’re gonna get sweaty.
