Yikes! "Don't buy any real estate near sea level"!!!

[leftchick]

Now we know: Canada melt down

:scared:

http://news.com.com/2061-11204_3-6146317.html

Using high tech monitoring devices, including satellite images, scientists have reconstructed a major climate event that occurred on August 13, 2005. That afternoon the forty-one square mile Ayles Ice Shelf broke free of Canada's Ellesmere Island. It now floats free, an ice island off northeastern Canada.

Satellite images and earthquake monitoring devices recorded the event. Nobody lives in the area so it was only digital evidence that existed. Now scientists have visited the newly formed ice island. Its position will be closely watched.

Only five Canadian ice shelves remain connected to land. And measurements show they are 90% smaller than they were a century ago.

At the recent Geophysical Union conference, one report said most Arctic ice will be gone by 2040. Don't buy any real estate near sea level.

1. I read somewhere the water level doesn't change

Because the water was supporting the ice to start with.

[Lurking Dem]

There is a displacement factor.

Ice like this that was in water will not change the sea level as it melts. Ice that was on land, however, will, and that too is melting.

[NashVegas]

10. Cold Contracts, Heat Expands

Is it not the same as it is with gases?

[Lurking Dem]

19. Actually, water expands when it forms ice.

That is why, in a weather forecast, 1 inch of forecast rain will result in 8 inches of snowfall if the temperature falls appropriately.

Fill a glass with ice and put water in it. Let it melt. The glass will not overflow.

Now if the ice is on land or solid to the ocean floor, that is a different matter.

3. not if the ice is on land

The South Pole is all land and much of nothern Canada's ice is land borne.

[Seattleman]

4. Common Sense

The ice that currently exists ON LAND may change sea levels when it melts, but sea ice should not have much effect.

[havocmom]

6. Some insurers already refusing policies for beach area homes.

When the corporations have to start taking action, one might surmise there is real trouble not too far ahead.

If ice on the sea is melting, so is ice on the land. Water levels WILL rise. ARE rising. Just this week, news of island the sea was taking back = population displaced due to rising water levels. More to come.

8. land ice vs sea ice...

<snip>

Claim: Global sea levels could rise by more than 20 feet (6 meters) with the loss of shelf ice in Greenland and Antarctica, devastating coastal areas worldwide.

There is little doubt that sea levels would rise by that much if Greenland melted.

But scientists disagree on when it could happen.

A recent Nature study suggested that Greenland's ice sheet will begin to melt if the temperature there rises by 3ºC (5.4ºF) within the next hundred years, which is quite possible, according to leading temperature-change estimates.

"It's uncertain how much warmer Greenland would get, a certain carbon dioxide level, because different climate models give different amounts of warming," said Jonathan Overpeck, director of the Institute for the Study of Planet Earth at the University of Arizona in Tucson.

But many experts agree that even a partial melting would cause a one-meter (three-foot) rise in sea levels, which would entirely submerge low-lying island countries, such as the Indian Ocean's Maldives (see Maldives map).

Claim: The Arctic Ocean could be ice-free in summer by 2050.

Some climate models are more conservative, suggesting that there will be no summer ice in the Arctic by the year 2100.

But new research shows it could take as little as 20 years for the sea ice to disappear.

14. However, it is holding back land-bound ice...

which, once the sea ice moves off or melts, will be unimpeded to the sea. In "An Inconvenient Truth", Gore says that Scientists believe that sea levels could rise as much as 20 feet from the break up of the ice shelves. That's not nuthin'.

[Amonester]

2. Ain't seen nothing yet...

Wait 'til Greenland's Glacier starts drifting away into the sea. It's gonna be this little planet's biggest mega-tsunami, and Wall Street is gonna sink for real.

Umm... Thinking about it, DON'T wait...

[mtnsnake]

5. Buy an inland hilltop in Tennessee. It could become an expensive island in the Atlantic

someday.

[Clark2008]

26. I already own one.

Lived here all my life and never expected to have sea-front property.

[shireen]

7. i wonder how people in the US are going to react to sea level rises

In the Netherlands, they've got sophisticated land reclamation efforts and flood control structures.

Would the US do the same for coastal communities? There are some options:
1) if they're rich communities, they'll be hiring Dutch engineers to protect their multi-million dollar mansions and hobby farms.
2) if they're poor or middle-class, they'll be displaced, forced to move inland.
3) maybe some people will get creative and build floating cities, unused oil rigs will go condo.
4) Landowners slightly inland from the coast will suddenly have beach-front property, driving property values so insanely high that only the rich can afford to live there. More displacement of poorer people inland.

Winners: rich people, real estate agents, mortgage brokers
Losers: poor & middle class, coastal ecosystems that took many thousands of years to develop.

Or hey! Maybe some nerdy scientist will make a giant ice machine to continually freeze sea water and dump it in the Antarctic to keep the sea level down. Kewl!

11. We will not keep our heads above water -- so to speak.

This will be the end of our pretension that we are a "first world" nation. It will be New Orleans everywhere. To many U.S. citizens, Mexico is going to start looking like a nice place to emmigrate to, and illegal immigrants from the United States will be seen as a problem in many nations, especially Canada.

[MadHound]

15. The Dutch will have their own problems

Despite their sophisticated and efficient systems of dikes, pumps, etc to keep water out of their country, if the shit truly hits the fan, Holland and the other Northern European lowlands are going under. The incoming water will be too widespread and massive for them to hold back.

Most American coastal areas will be gone. Most of Florida will be under water, as will NYC, Boston, Philly, etc. etc. If you truly want to think about your safety now, think west of the Appalachian Mts.

[Amonester]

17. Yup. And don't forget to bring some good recipes on how to...

cook roots, mushrooms, and wild stuff if you're vegetarian, or some good traps if you're not.

May be helpful to have something to eat for a little while...

[leftchick]

18. exactly right

we are talking loss of some major land mass world wide. I imagine in my State of NC, Raleigh will be the new oceanfront city.

[Strelnikov_]

9. Buoyancy

A solid body immersed in a fluid will have an upward buoyant force acting on it equal to the weight of displaced fluid. This is due to the hydrostatic pressure in the fluid.

In the case of a container ship, for instance, its weight force is balanced by a buoyant force from the displaced water, allowing it to float. If more cargo is loaded onto the ship, it would sit lower in the water - displacing more water and thus receive a higher buoyant force to balance the increased weight force.

Discovery of the principle of buoyancy is attributed to Archimedes.


When the ice melts, it attains the same density as the water displaced, therefore no change in volume.


Ice on land, on the other hand . . .

Greenland - 7m
Antarctica - 60m

All land ice - 80m

12. Investing in global warming.

Your post got me thinking. I wonder if there are any mutual fund products that bet on global warming. It looks to me like there is another ice shelf called "head in the sand corporations" that is looking to fall into the ocean.

[tridim]

29. Invest in cartography companies

Lots of maps will need to be redrawn.

[n2doc]

13. South Florida is going to make New Orleans/Katrina look like a practice run

Most of Miami is only a few feet above sea level. Gonna be losing a LOT of electoral votes in the future....Hopefully people will have enough time and sense to get out before they get driven out by continuous flooding.

[gilpo]

16. The US will suffer, but China and India will have, by some estimates 100 million

people displaced if the sea level rises just 20 feet. Darfur had about 2 million refugees for comparison.

[Radio_Lady]

23. Gee, just when I was wondering how much the tidewater land and house my parents bought in 1955...

would appreciate in value over its more than $1 million value today.

[Greyhound]

27. Sounds like a good time to sell. n/t

20. Earth's first totally submerged island, 10,000 displaced

I'm not aware of any U.S. corporate media reports on this story yet. I heard about it on the Christmas Eve edition of Max and Stacy's radio show:

http://karmabanqueradio.com/?p=268
http://www.karmabanqueradio.com/podcast/kbqr241206mp3.mp3

I think they said it was an island in the Indian Ocean off the coast of India.

[electricmonk]

22. You beat me to the story

After I hit post I saw you beat me by a few minutes. :hi:

[redacted]

25. Hi electricmonk! Thanks for posting the Independent article with the link.

Didn't mean to hit the "post" button first. This story is so huge, we need as many folks as possible posting this in as many different online forums as possible. This issue must finally be getting traction if both you and I are working on it at the same time.

:yourock: :headbang: :applause:

21. Forget about your dreams of owning a tropical island too

http://news.independent.co.uk/environment/article2099971.ece"> Disappearing world: Global warming claims tropical island

-snip-
Published: 24 December 2006

Rising seas, caused by global warming, have for the first time washed an inhabited island off the face of the Earth. The obliteration of Lohachara island, in India's part of the Sundarbans where the Ganges and the Brahmaputra rivers empty into the Bay of Bengal, marks the moment when one of the most apocalyptic predictions of environmentalists and climate scientists has started coming true.

As the seas continue to swell, they will swallow whole island nations, from the Maldives to the Marshall Islands, inundate vast areas of countries from Bangladesh to Egypt, and submerge parts of scores of coastal cities.

Eight years ago, as exclusively reported in The Independent on Sunday, the first uninhabited islands - in the Pacific atoll nation of Kiribati - vanished beneath the waves. The people of low-lying islands in Vanuatu, also in the Pacific, have been evacuated as a precaution, but the land still juts above the sea. The disappearance of Lohachara, once home to 10,000 people, is unprecedented.

24. Ok I researched this a bit and yes scientists already know

that
the Islands are going to be taken by water
from somewhere??? how can islands be run over by oceans well if large pieces of Antartica is melting and Artic is melting... it means more water

Water is differrent than Ice it moves quicker

Scientists have noticed the water levels increasing at the Equator

The Sundarban Islands being overrun first scientists thought Carteret Islands off Papua New Guinea would be first so their models are not accurate
I looked on the map and there are many low lying islands

Maldives Marshall Islands and others

The island Sagar where the refugees went is being overtaken by water

How Long can the world deny Global warming
