The danger is perhaps a little overstated. I’m more worried about the effect of a Carrington event, or man-made EMP, than a methane bubble in the ocean. If our power grids go down, society will go feral within a year.
Well. Being just a few miles from the coast here in Fairhope, AL reports like this tend to grab one’s attention just a little bit.
But if it does happen those of us this close to the coast won’t have to worry about what comes next or how do we survive long term. For us there won’t be a next.
The rest of the world had better get used to the fact that they may have to fix their own problems from now on. No more US to kick around and pay the bills.
Hey you UN critters, start packing your bags and plan to move to the Middle East or somewhere in Africa.
Plenty of near extinction level events (occurred in past) that are due: Massive Solar Flare, Yellowstone Supervolcano eruption, Katla (or other large volcano) eruption causing an ice age, Worldwide Pestilence, Gamma Ray Burst, Magnetic Pole Reversal, Iran nuking Israel (not yet), large commit strike, Massive Underwater Lava Eruption, etc...
You can only die once.
EDIT: If our power grids go down, society will go feral within a year. in 90 days or less.
