To hell with boats I just want to find a cave with the " nubile breeding stock". After that who cares.

Nah. Just sail further inland.

Think of all the obstacles on which your anchor will get stuck.
Power lines, buildings, trees, fences, the list is endless.

Yes but just think of all those uncrowded anchorages you would have access to with no danger of dragging.

tie to top of a friends house in iowa...LOL....but only if he hasnt found a way to float the dwelling.....

DOD sponsored a symposium, here is the link.

Natalia Shakhova has been studying methane release in the East Artic for quite a while. Below is the abstract from here presentation. The whole presentation can be found at the link above.

METHANE RELEASE FROM THE EAST SIBERIAN ARCTIC SHELF (ESAS) AND THE POTENTIAL FOR ABRUPT CLIMATE CHANGES

The ESAS is a unique area of Earth’s oceans for a range of reasons. (1) No comparable region has such an extensive continental shelf area (~10% of the global continental shelf area), hosting such thick sedimentary basins (up to 20 km), which provide favorable conditions for methanogenesis; (2) Most of the ESAS methane potential is represented as previously produced CH4 stored as natural gas, CH4-hydrates, and CH4-bearing fluids, ccumulated beneath and within sub-sea permafrost; (3) ESAS seabed CH4 emissions are geologically controlled; specifically, by sub-sea permafrost, which for thousands of years was stable and impermeable for gases. Permafrost failure uncorks the huge gas reservoirs, leading to large-scale releases, which are not time and temperature dependent; (4) The ESAS is a major reservoir for permafrostrelated shallow Arctic hydrates (more than 80% of existing subsea permafrost); and (5) The ESAS is very shallow, which provides a short conduit for seabed CH4 transfer to the atmosphere.

Thus, potential CH4 release from the ESAS is enormous.

Numerical models predict permafrost destabilization 5-10 kYr after inundation, depending on the duration of inundation relative to the duration of previous freezing. Currently predicted talik (i.e., thawed sediment within permafrost that permit CH4 migration) area comprises up to 3-5% of the ESAS area. Recent data suggest that at places subsea permafrost is experiencing significant changes in its thermal regime. For instance, the temperature of subsea permafrost measured in deep boreholes (down to 70 m) 20-km offshore the NW Lena delta was as warm as -1°C, while in the same area terrestrial permafrost had a much lower annual mean temperature (about -12°C).

Available geophysical data identify numerous gas seeps over extensive sea floor areas and suggest the ESAS subsea permafrost is leaking substantial CH4. Recent data collected from the ESAS illustrates substantial and widespread failures in the carbon trapping efficiency of sub-sea permafrost, leading to large-scale CH4 release. A total annual venting flux of methane to the ESAS atmosphere was estimated at ~8 Tg C- CH4, which does not include non-gradual “catastrophic event” ebullition. Such non-gradual methane pulses occur over the ESAS, but their spatial and temporal pattern is uncertain. Additional components to be incorporated to the annual flux are releases associated with: seismic and tectonic events; permafrost breaks; sediment settlement and adjustment caused by hydrate destabilization; releases from coal sea beds; storm events; deep fall convection; ice-break period; winter releases through flaw polynyas and leads.

Recently obtained observational data, confirmed by modeling

results, gives evidence that incorporation of only one component (non-gradual releases from hot spot areas) could increase reported numbers orders of magnitude.

I think the EOTWAWKI question on every experts lips is: Can zombies swim?

Consider that when fitting out your floating bunker...

Well ... I wouldn't anchor over somewhere like New York...you'd need a really good trip line.
Hey....
Imagine anchoring over the Sahara Desert.... I bet that would be good holding.

The media in particular seems to swallow computer models as certain reality, but most models are usually rubbish outside of very narrowly defined limits and ALL models massively simplify effects and neglect critical factors so that they can focus on the narrow range for which they are valid. . . .

Computer models are nice but Mother Nature has rarely if ever paid any attention to them. She does what she wants to do and is also infinitely more complex than any computer model can ever be. Just look at the daily (actually 4 times per day) GFS weather computer models (GRIBS) we cruisers use. They change dramatically from one to the other and as you get out to the end of the forecast period they are of little more use than a "trend indicator."
- - Although "end of the world" scenarios caused by global/weather shifts were covered nicely in the old thread of apparent Plankton loss, et.al.
- - "End of the world" or at least the developed western world by political or social/economic collapse is probably more relevant. Ever since Plato's time, the end of civilization has been predicted or lamented. Civilizations rise and civilizations fall, and being able to sail away on your boat to places less hazardous to your financial and physical health is a big plus.
- - It is fun to suppose a "Water World" movie situation, but I am more concerned by the chaotic and lunatic political/social trends certain first world countries. These represent a real and present danger.
