Ancient Antarctic ice sheet collapse could cause a global flood

[Maverick]

I thought the homo sapiens cars were foot powered? Who of thought they could have been at fault *sigh

The study, presented at the American Geophysical Union earlier this month, highlights the concerns and the risks involved if the sheet ─ which originally disappeared 125,000 years ago because of a changing climate ─ were to collapse.

Boston College paleoclimatologist Jeremy Shakun said that it may not require much for the West Antarctic ice sheet to move, which could cause ocean levels to rise as much as 8 feet per century.


Now isn't That 3 feet for every 100 years?..guess i won't worry to much about it.

In 100 years (maybe-never) those high tides will have a whole new meaning to those multi-million dollar beach front properties. Those living along the coasts, may want to move a bit further inland.

I’m 1400 ft above sea level here. Maybe in a thousand years the property will be beachfront. The bad thing about oceans rising is every time a storm gets near land it will cause massive financial damage from flooding. Considering that there are so many coastal cities it will be of major importance to our children and grandchildren.

The ice in Antarctica is and has been flowing away from the South Pole towards the sea ever since the ice was formed. The South Pole is at an elevation of 10,000 feet above sea level. Much of the land under the ice is compressed by the weight of more than 2 miles of ice.
In the late '90's and early 2000's I was involved in a drilling project on the polar plateau to measure the speed of the ice flow. What was called "fast" flowing ice traveled at a speed of something like an inch a day. Other areas flowed a couple feet per year. The average snow fall on the polar plateau is about a half inch per year and the average summer high temp is around -35. Interestingly there is a thin layer of water under that 2 miles of ice created by friction from the movement of the ice. All of this ice flows out on to the ocean and eventually it breaks off due to ocean currents and the shear weight of the ice. It has nothing to do with global warming. There is zero danger of the Antarctica ice shelf or the polar plateau melting in a thousand generations.
Near the Russian base of Vostok there is a lake under the ice that is the size of Lake Superior called Lake Vostok.

the Ocean is a power full force,,those that decide to live close to the ocean will always be at risk from storms and rising seas

 

[bigpaul]

storm surges and spring tides are always a problem if you live near the coast.

I'm shy of 4000' above SL 70 miles from the coast (way the crow fly's) It would take an awful lot of water to get to me from the ocean edge.

Isn't a century 100 years? So it could be up to 8 feet in a hundred years? Well, I figure with all this technology they can figure out what to do about it then. I won't be around to see it.

Just finished an article about floating houses (not house boats) . Sea rises, not big deal. Don't like the location, up anchor and motor (no sails) to a new location. Totally self contained house / home, power wise, not sure about sewer system. By the time this is NEEDED, it will be debugged and viable. Forget about the price of land, I guess you will just be renting GPS coordinates. Just something to keep in mind.

 

[bigpaul]

not a problem where I live, about as far as we can get away from the coast, any further and we would be heading out of the county into the next one.

I think a lot of people spend too much time reading and watching science fiction. The Antarctic ice shelf isn't going anywhere. What the "experts" don't say is that the ice shelf is floating on water, which means that it's already displaced the water. Even if the entire ice shelf melted tomorrow it wouldn't raise the sea level any. Also, the ice shelf doubles in size every winter.
These global warming nutjobs depend on people's gulliblity and ignorance to sell their BS.

I'm sure when the Sun dims in a million years, rising oceans would be the least problems for the human race. We are more likely to be hit by a meteor in our life time than the ocean rising enough to impact us, So, in mean time I going to carry on doing what I'm doing and continue wishing for some alaskan halibut at the property edge.
