Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Strong Quake Strikes Baffin Bay

Posted by feww on July 8, 2009

Magnitude 6.1 Earthquake Occurred at Baffin Bay off the NW Coast of Greenland

FEWW Moderators believe magnitude of the seismicity most likely intensified as a result of icemelt in the region.

Other examples of climate-intensified natural events would be posted on this blog when they occur.
