Rising Seas

Here's an article about areas affected by rising seas due to climate change.
The topographical analysis sounds about right, although I will add that while areas up to 10 feet above current levels will be submerged, storm activity will make quite a lot more space beyond that unsafe to inhabit. Remember the storms are getting bigger!
Also, completely ignore the handpatting about how this will take a long time to happen. Timespans of change are being underestimated by whole orders of magnitude; things are already happening that were originally predicted for centuries in the future. The truth is, we're breaking the atmospheric integrity in ways we know nothing about, and we cannot accurately predict the degree to which we have fucked ourselves. My current estimate is that if you live within daytrip distance of a coast, it would probably be prudent to move inland.

Not happening.
So my kids are going to (maybe) raise kids in a world which is /definitely/ worse off than we are today, than we were in 1984, than we were in 1944.
Pretty soon, we're going to run out of PLANET.

As far as I'm concerned, if you're holding 80% of the wealth, you are obligated to pay 80% of the bills. Conversely if you have no resources, you have no obligations and instead are owed resources.
>> Not happening. <<
Problem.
>> So my kids are going to (maybe) raise kids in a world which is /definitely/ worse off than we are today, than we were in 1984, than we were in 1944. <<
We're already losing ground in terms of health and life expectancy, let alone standard of living.
>> Pretty soon, we're going to run out of PLANET. <<
Sadly so. Infinite growth in a finite system is the philosophy of the cancer cell, and we all know how that ends.

They're saying it'll take two centuries or more for the West Antarctic ice sheet to collapse. I don't believe it, either.

Date: 2014-05-14 09:05 pm (UTC)You possibly know I run a ongoing climate model, part of my own research, which is a sum over predictions. [basically taking an average of the best guess predictions from various sources.] I've been doing this since the 80's, in one form or another.
Based on this, and taking into account current trends and geological data, we're looking at a loss of around 45-60% of currently inhabited coastal land, and a displacement of around ~25% of the estimated population of the western hemisphere.
I'm not even going to guess the impact this will have, but combine this with a probable loss 75% of arable land due to drought and ground-water contamination by salt... well, it's not good. It's going to take some heroic measures just to prevent civilisation from imploding.

Date: 2014-05-14 10:41 pm (UTC)Which is where my job takes over. Inspiring heroes is Who I Am in the VERY large sense; but what is inspiration without knowledge? So teaching, and providing access to information, is a part of that.
Even with this, however, it's going to be desperate. Western culture barely acknowledges the dynamic of people as a single group, much less people and land in a relationship together. With that disconnect from each other and our environment in favor of a strong connection to money as a substitute relationship, how can we get enough people in power to observe the truth about what's happening and act on it effectively?
The only way is to turn everyone into heroes -- heroes who work together to turn the tide, like the stories told of the Celtic gods (who had to team up and organize who was doing what in order to win).

Thoughts
Date: 2014-05-15 01:58 am (UTC)Sadly most of the people in power are still in massive denial, and trying to convince other people that everything is fine. They sound like addicts.
>> That's basically what I'm trying to do. <<
Same here.

I have really had no luck with this.
Re: Thoughts
Date: 2014-05-16 03:17 pm (UTC)First, http://ssi.org , The Space Studies Institute. An unlikely set of heroes, if one doesn't like nerds and engineers with computers.
Founded by Professor Gerrard O'Neil, he taught civil engineering. One day, he added a "fun" calculation to his class exam: since they already knew how to calculate the specifics of a suspension bridge, do the very same calculation for a space station which was exactly a suspension bridge that was circular.
He was surprised that the answers were amazingly workable, a space habitat 25 miles across. Going on from there and relying on the math and engineering alone (no wishful thinking), he and his teams have shown exactly how we can produce our own living area in space out of the materials out there -- so that, when our Earth is not room enough, much of humanity can be living off-planet anyway.
In a nutshell: a step-by-step plan that produces space habitats from materials outside Earth's gravity well, and the habitats produce more space habitats. The first makes another, those two make two others, and those four, in another eight cycles, make a thousand of them. Each ten cycles bumps it up that way, to a million of them, to a billion of them, and ... in a matter of decades, there is more land area in the habitats than on Earth and more people living up there.
* * * * *
And my point here -- as we make our own situation on Earth even more desperate, it will be easier and easier to get the population interested in moving out into space.
----> Expect that desperation soon <----
My home town in Massachusetts was very ho-hum and in denial about an ecological disaster waiting to happen. (The town dump was polluting the water supply underground.) As nearly always is the case, by the time it becomes "undeniable" and everyone believes, it has become "far too late". (When the town's beaches and lakefronts and reservoir started smelling, they all got upset, but the worst was, and is, still yet to come.)
When the global warming crisis is undeniable, it's probably too late to stop it.
The second -- Well, Wordsmiths, Authors, and Bloggers can be screaming about the world that's coming. One really good book or movie about the refugees trying to escape ocean waves, while the rest starve looking for some place where nature still favors growing food, that could get people worried. While stories about a 23rd century in which we have SOLVED this crisis would perhaps inspire them in a direction of practical effort.
* * * * *
This is REALLY timely, given the two papers published Monday on how the West Antarctic ice sheet is melting much faster than predicted, and in an unstoppable way.

Date: 2014-05-17 12:29 pm (UTC)The bit about writing stories about the-horrid-world-to-come is still worth doing.
o The ABC TV special "Earth 2100" (based
on the graphic novel) was a pretty
good dramatization of how the Global
Warming issue could mess everything up
(still on youtube, still on vimeo at
http://vimeo.com/79730798 ).
o Stanley Kramer got people to worry
about our ability to thoroughly mess up
the planet with the film
"On the Beach"; Linus Pauling called it
"the film that saved the world".

>> areas up to 10 feet above current levels will be submerged, storm activity will make quite a lot more space beyond that unsafe to inhabit. Remember the storms are getting bigger!
Too many people, too little planet. Eventually moving people off planet (please remember to check SSI's math, the numbers are correct) will indeed alleviate the global strain on the ecosystem. Meanwhile, no storms and flooding or seas in the space habitats.
>> we're breaking the atmospheric integrity in ways we know nothing about
See the above, but also we will learn a lot about how atmospheric systems work when we've had to manage a couple of our own that we've created.
>> the lifebearing resources will still have to come mostly or wholly from Earth...
There is water and oxygen (and everything else we need) out there to be mined -- and that's the approach presented.
>> it's the Jedi Tree problem; we must face whatever we bring with us.
Which is true whether we go or not.
Yes...
Date: 2014-05-15 01:47 am (UTC)Yeah, I've been doing that since my toddler years. It's frustrating how little progress I've made. But I follow the Oracle rules: It is my job to present information. What other people do with it is their responsibility.
>> Even with this, however, it's going to be desperate. Western culture barely acknowledges the dynamic of people as a single group, much less people and land in a relationship together. <<
Yes, that's a problem.
>> With that disconnect from each other and our environment in favor of a strong connection to money as a substitute relationship, how can we get enough people in power to observe the truth about what's happening and act on it effectively? <<
We can't and they aren't. There isn't time to change the whole cultural paradigm before the biosphere collapses to a lower level of stable function. There's too much cultural momentum in the current direction.
>> The only way is to turn everyone into heroes -- heroes who work together to turn the tide, like the stories told of the Celtic gods (who had to team up and organize who was doing what in order to win). <<
That's something else I try to promote, again with minimal success. Being a hero is WORK. People these days don't want to do that. They flee when I ask them to do even basic things.
Feel free to prompt for heroic teamwork, though. I'm happy to fantasize about it.

Date: 2014-05-15 09:17 pm (UTC)They didn't make it sounds like horrible, onerous work, but they did make it seem like work. I appreciated that. (And I mourn how few stories talk about that. A fighter doesn't need to practice daily, but will know there needs to be regular practice or one starts to lose one's edge. If you've practiced a lot of sparring, an ordinary punch/kick/thrust/swing/parry (should that end with a SPROING and a bent back beak?) seems comfortably slow; as practice recedes, they start to seem faster and faster again.
Re: Yes...
Date: 2014-05-15 09:39 pm (UTC)That sounds great. I wrote one poem about the apprentices of several adventurers getting rudely shocked by how dangerous the trade could be and how much work it took to prepare for, but now I can't find the darn thing.
>> They didn't make it sounds like horrible, onerous work, but they did make it seem like work. I appreciated that. <<
That's good to hear. I made a point of this in Polychrome Heroics, where some poems such as "Through the Haze" show Damask practicing, and others like "The Hall of Mirrors" show different kinds of preparation.

Agreed. Feel free to ask for things like this in any of my relevant prompt calls.

Date: 2014-05-15 02:01 am (UTC)A secondary point is of course that although your average sea level will rise X amount thanks to global climate change, the highest level will actually be some function of X, and thus higher. The maths is pretty frightful, but since tides are basically this large bulge of water sploshing around the oceans, if you increase the average hight of the sea itself the the volume of the bulge increases as the cube power... which is a complex way of saying your high tides get a lot higher if you increase your average sea level just a bit. [actually it's a lot more complicated than that].
But a rough back of the envelope calculation by way of example, a 10ft rise in sea levels means that whereas normally you'd get a coast line that would see a 4ft difference in tides, you'd see a 35ft tidal difference

Date: 2014-05-15 01:00 pm (UTC)A storm surge [S] can be upto three times [300% increased] above this average level[A] so if Ht is 4ft above A, then S is ~12ft. [although the actual amount is dependent on a lot of variables, so that's just a ballpark figure]
However, the separate point I made was that if you raise A by 10ft, then Ht-A is also increased by a complex factorial [which is calculated using the equation for area under a curve, in 3D to give the volume of the tidal bulge] But essentially it means that by increasing the average sea level by a little, you increase where the high tide is by a lot.
(no subject)
Date: 2014-05-15 04:44 pm (UTC)This is where you are putting it badly. "Relative to average sea level, a storm surge can be 300% higher than high tide" expresses this more clearly. The base sea level does not give you anything to have 300% of; you need that *and* the high tide level.
And yes, please do provide the calculus formulas for the increased high tide level -- my 3W+T was based loosely on your "300%" assertion, but now it sounds like you meant the 300% increase of storm surge over high tide to be a constant factor, but the increase in the high tide level over the average level as the average level increases is you are asserting is ...?

None of which ever satisfy them no matter how much exhaustive detail one goes into... and then when you give up in disgust they claim victory and say you cannot prove what you said.
Well, sorry, but I'm not playing that game mate. I've answered your question, if you genuinely want better answers then A; get a maths degree and work it out for yourself, or B: google it. I'm not your search engine or tutor.
