Could one pierce a bubble and syphon/concentrate the gas into a tank with a pump? Might be too late, considering how many there are and how remote they are.

edit: nm, I saw that conference where they've shown Methane releasing from the submerged Siberian plane. We're fucked.

Here is a good video about the arctic methane emergency: https://www.youtube.com/watch?v=8F9ed5E54s4 Some summary points: - Total amount of methane in the current atmosphere: ~5 gigatons - Amount of carbon preserved as methane in the arctic shelf: estimated at 100s-1000s of gigatons - Only 1% release would double the atmospheric burden of methane - Not much effort is needed to destabilize this 1% - The volume current…

Methane has a short ~5-10 year half life in the atmosphere. So, releasing 50x current methane levels over 100 years does not triple current methane levels.

In layman's terms, how much are we screwed without hope of a solution, and what is the rough timeframe before the evening news starts looking like "The Day After Tomorrow?"

I'm wondering the same thing. Should I start blowing through my 401k money now or what?

Save it for your ticket to mars.

I know it's stupid and crazy, but would carpet bombing the arctic work to burn up the methane trapped below the permafrost before it leaks out into the atmosphere and causes worse problems? Or maybe we should send out expedition crews to find and preemptively explode these methane bubbles. Perhaps the way things are going they will become too plentiful to really do anything realistic about it.

How about just spreading a bunch of methane consuming bacteria over there? Not quite suited to the environment - how about breeding some that are?

There is some hope. We could geoengineer a giant shade structure to reflect sunlight away from earth. It would cost $trillions (twelve zeros) but it could be done with current technology. And it would cool the Earth immediately. Unfortunately it would do nothing to fix ocean acidification, which threatens to starve and/or suffocate us all.

That "solution" fucking sucks. We kinda rely on the sun to grow plants and power life, you know?

Not in the deserts or the oceans, we don't.

I suspect that the interests driving denial are planning to ride the crash. There are probably developments in favorable locations. Land. Security. Infrastructure. Resources.

Does somebody have climatology models reliable enough to determine a favorable location? AFAIK, anything can go wrong anywhere.

Maybe so, but I'm sure that good guesses are possible. Basically, further from the equator, away from oceans, and higher altitude. And away from large cities. I wonder about some of those "useless" Chinese cities, for example.

Yeah, exponentials are tricky. By the time danger is clear, it's too late to do anything about it. But hey, at least this will probably be self-limiting. Disruption will arguably reduce population and industrialization, and so CO2 emissions will drop.

And then good luck rebuilding civilization now that every easily accessible resource has been mined/harvested out.

Read Stephenson's Anathem. There's lots of good stuff in cities. And in landfills.

If we can't fix, if we can't prevent, and if we cannot prepare either, then maybe we could at least preserve?

• Digitize all human knowledge and as much art/literature as you can gather (books, music, movies, shows, games, even porn and random YouTube videos and discussions on online forums :) Most of that work has already been done.

• Store it on the most resilient (and simple/repairable) storage media you can,

• Bundle it with devices that can read that data,

• Along with instructions for building/reinventing such devices, and instructions on how to interpret that data (i.e. JPEG and other file formats :)

• Also include a guide for translating the instructions. Assume that a future reader may not understand any of our current languages, or even be human at all.

• Put it all in a silo as physically strong as you can build.

• Make copies of the silo and bury one on each continent and in each ocean. Maybe even on the Moon?

• Distribute markers and maps to each silo (and instructions for opening them) all over the world.

• Let fate take its course.

All of this could be done by a few individuals and most of it won't even require a lot of money.

Useless buildings are a great supply of resources, and for certain resources they are arguably even easier to access.
