Since I live over one thousand feet above sea level and it'll
be a long time before they're tying up at my front gate, [+] |

//This Idea is for all those people being derided as
"trailer park trash" simply because they don't live
in a fancy house.// |
|
| |
I resent the implication that I deride people
simply because they can't afford a fancy house. I
deride them for so many more reasons than that. |
|
| |
Seal evils have risen quite steadily by about 2mm
per year over the last 200 years, which would
imply that a 60 metre rise will happen by about
August of 32103. I strongly suspect that most of
the leases on mobile home plots will be due for
renewal before then. |
|
| |
I would be happy to be a house guest at your postdeluvian hovel, provided that the Seal Evils aren't too much of a problem. |
|
| |
[MaxwellBuchanan], I haven't implied at all that
you were one of those who derided people living
in mobile homes. And, regardless of whether or
not there are multiple rationales for such derision,
only one of those rationales needed to be pointed
out for this Idea. |
|
| |
Regarding the rate of sea level rise, it is not
necessarily wise to assume the trend you
described will continue at exactly the same rate.
After all, the warmer things get, the FASTER ice
melts.... |
|
| |
Remember to pack your doves. Although it may be true
that ice will melt and enter the oceans and be evaporated
more quickly by the generally warmer atmosphere. I am
not sure albedo nly one trying to correct that problem. May
take a few centuries though. |
|

[21Quest], the icecap covering Greenland is (or
was) two miles thick in places (a little more than 3
kilometers). All of it will contribute to sea-level
rise. And most of the ice in Antarctica is located
on land, not sea. I once read a science-fiction
story that included some stuff about the West
Antarctica Ice Sheet; in the story it slid off the
continent and immediately raised sea level by 18
meters or so... The 60 meters I mentioned in the
main text here is what is believed to be probable,
after all the ice-over-land melts. |
|
| |
No, you aren't missing anything except the fact that
the dudes who figured a 60+meter sea level rise have
already taken it into account; they are talking about
the effect of ice that is currently not floating on the
sea. |
|
| |
Meh, most sea level rise isn't ice melt anyway. |
|
| |
Water expands as it gets warmer, just like most
materials. The amount varies with pressure, but it's
somewhere around 52e-6/K. So a meter of sea water
only expands 52 micrometers per degree Celsius
increase, but the 10km Challenger deep adds half a
meter for the same increase. |
|
| |
Would anyone care to guess the amount by which
the coverage of the arctic ice cap has changed in the
last year? |
|
| |
It has changed by just over 500,000 square miles
since 2012. |
|
| |
If anyone thinks that's a warning sign, I have an
additional fact for them. |
|
| |
Yes. By about 30% compared to 2012. |
|
| |
No doubt a 30% growth in ice cover is a sign of the
disturbance of the ocean currents due to global
warming, in contrast to a 30% loss which would be
a sure sign of global warming. Except it hasn't
been 'global warming' for a long time and is now
'climate change', which explains why the last few
winters have been amongst the coldest in recent
memory, and why winter 2013/14 is set to be
particularly harsh. |
|
| |
We ought to be capitalizing on this new physics.
Now that warming can make things colder, whole
new energy cycles become possible. |
|
| |
98% of climate scientists support the notion of
global warming, in much the same way that 98% of
mycologists would support the idea that the
greatest threat facing mankind is killer fungi. |
|
| |
[MaxwellBuchanan], there is another factor
besides all that CO2 (and methane) that humans
have caused to be added to the atmosphere. This
factor is the Ice Age Cycle. In terms of planetary
orbital cycles, eccentricity changes, axial tilt
precession and degree-changes, etc. the Earth is
about "due" to exit
the last InterGlacial Period (which is what most
climate has been like for the past 10-15 thousand
years or so. |
|
| |
The anthropogenic aspect of Global Warming is
real, and it may be the only thing keeping us from
entering another Ice Age. Lucky us. Except, of
course, anything that can be done can also be
over-done. We shall see, which way the Global
Thermal Balance ultimately tips.... |

Max, you are mature enough to recognize that
attempting to map a trend by comparing one year's
data point, (and a particularly oddly wintered one,
that is) is disingenuous. |

Mobile homes are designed to have say 18 inches of dead dry air beneath them. Won't be there in any conversion. |

The metal frame they are built on will rust if parked next to ocean. Floating on top just means more rust faster. |

[+] trailers are pretty well naturals for a nautical conversion: standard'ish width and lengths; the unaerodynamic shape non-sequitur at water speeds; the bit underneath a good place for a fuel tank, perhaps an engine. The width limitations for a road-going vehicle compared to a lakecraft means there can be a surrounding walkway. |
|
| |
So, it's like the Kraken Wakes, but with trailers? |
|
| |
Add to all of this the natural tendency for tornadoes to seek them out, and we'll have a great time. |

//Max, you are mature enough to recognize that

|
| |
You're quite right, and I was being disingenuous. I
should take as my guide the IPCC (actually its
forerunner), under whose
auspices a statement was made in 1998 that a rise
in mean global temperatures of greater than 0.2°C
over the next decade would be a sure sign that
predictions of global warming were essentially
correct. |
|
| |
Or, I could instead take as my guide a statement
issued a few weeks ago that global warming could
only be reliably detected by monitoring
temperatures over a period of at least 25 years.
This statement was made in response to the
quietly-released finding that there has been no
net increase whatsoever in mean global
temperatures over the last 15 years. |
|
| |
Incidentally, the phrase "climate change denier"
has gained considerable currency of late. It is
interesting that this distinctive term for anyone
holding a different scientific opinion has been
closely modelled on a phrase applied to right-wing
morons who deny the existence of the holocaust. |

specific heat of water 4.2 J/g

Or, if you want clues, ice at 0C melting to water at 0C is the equivalent of an 80 degree Celsius increase. |
|
| |
When you put ice into your drink it will keep your drink at a consistent'ish 4-5C until it melts |

After the ice melts what happens ? how fast does it happen ? |

Polar ice cap measurements go back 150 years. |
