THERMAL EXPANSION of the Earth's crust due to global warming risks disturbing Arctic methane hydrates, and the process has already started, necessitating geo-engineering, argues Sam Carana, editor of the Geo-engineering Blog.
In a search for the smoking gun, locations of Arctic temperature anomalies were used to pinpoint methane emission points, which were subsequently matched with seismological data.

Extrapolation of the data points at Total Extinction Zones during which all organic life on Earth risks going extinct, due to accelerating release of methane from Arctic hydrates destabilized by Gakkel Ridge earthquake activity.
This danger necessitates geo-engineering, argues Sam Carana, insisting that temperatures of the water deep down in the Arctic Ocean need to be brought down rapidly, while carbon dioxide levels need to be brought back to 280ppm in the course of this century, as part of a comprehensive plan of action that will lead us Towards a Sustainable Economy.

Huybers and Langmuir (2009) proposed that glacially induced volcanism, triggered by the depressurization of the upper mantle increased the frequency of volcanic eruptions worldwide, and thus plays a key role in the atmospheric CO2 balance and ice‐age cycles. A link between arc volcanism and the 41 ka Milankovitch periodicity also emerges from a statistical evaluation of macroscopically visible marine tephra deposits near circum‐Pacific arcs (Jegen et al., 2010). On a more immediate scale, Tuffen (2010) concluded that ongoing glacier recession likely will result in intensification of eruptions worldwide, with a corresponding increase in associated hazards.

btw. you leave any explanation for the term Total Extinction Zone out and the planetary alignment makes no sense.
Cheers
