Causes of recent sea level rise?

Well the land ice sheets of Greenland, the Permafrost in Russia, glaciers and Antarctic glaciers and submerged ice have all been melting at a rate faster than previously measured. This water enters the oceans and of course because it is fresh, changes the salinity. In many areas, the melt water is warmer than the ocean it enters. The average global temp has risen due to man made interference, and one aspect of this is warming oceans and great amounts of CO2 being both absorbed by the oceans and ending up there due to runoff from streams and ground water, increasing the acidity a well. I don't understand exactly how water finds it's level, but the seas are rising in some places and not others.

Global warming was predicted to rise the oceans, cause droughts, floods, heavy rains, tornadoes, cyclones etc The deniers here like to ignore the truth. All you really have to do is read the news about how climate change IS affecting Bangladesh. Bangladesh has been wrought with drought, and starvation for decades and now it is a target of climate change. The bay is rising far too fast for it's people to adapt.

The more the land ice melts, the higher the oceans will rise. I think the prediction of a foot increase by 2050 is very conservative.

*****Ian...This is taken from the mnn.com link you provided. "Scientists pored over satellite data from Canada, Germany and Japan spanning from 2000 to 2011, and found that Greenland's largest glaciers, which end on land, move rather slowly, between 30 and 325 feet per year." So these unnamed scientists poored over data from Canada, Germany and Japan to determine the melt of Greenland ice sheets. How ridiculous can you get. What the pjpijh do these countries have to do with Greenland??????????? No link to the study and contains quotes by people involved who have no credentials listed.

The Science daily article, while interesting is challenging models regarding a specific eastern portion of Antarctica, the Fimbul Ice shelf. Interesting that the reported significant melting in Antartcia is in the Western portion. What I have read regaarding this is that eastern Antarctica may be stable and possibly gaining ice while the western area is melting.

If you would like to learn a little dam history from the 20th century read "Encounters with the Archdruid" John McPhee

Honestly the ars article sounds like a crock of "S" to me.

Hi Jeff

I think Trevor has posted in depth reads on how the ocean and atmospheric water budget works I think you have even taken the time to explain it How I see it is the oceans are were the densest parts of the atmosphere settle That's why they are in equilibrium " what goes up must come down" so to say. Anyway there's heaps on the net about the process. One thing I don't see much talked about is over time as the earth cools it would shrink and the crust would either push up in places or down in others this would alter the height of the water at certain places . The only way's to get a accurate measurement would be to measure from a fixed point in space or from the centre out so with today's techs there should be no question to ask, if you can get your hands on the data that is. One thing that climate change could do is speed up to a point that is recognizable to us all is the silt or rivers carry to the oceans the more rain that falls on the land the more silt (mud, salts and minerals in the natural proses) but man has added more chemicals through our farming and industrial proses which in turn alters the chemical make-up and Ph of some rivers and coastal areas and has a major Impact on the marine life. Major river delta systems have been so altered to accommodate the population at the time and can't cope with the extra catchment run off rate of today's land clearing either for farming or housing and industrial development. Any way Jeff like I said when it comes to ocean heights over a long period I go with the expansion and contraction that is created by this proses

http://www.ornl.gov/sci/radiation_transport_critic... Also J made a good point about oil extraction We use oil in or cars to help in cooling the engine more then a lubricant and oil has a much higher boiling point then water So by extracting oil out of the ground and replacing it with water will change the black-body radiation that is emitted from the earth to atmosphere and oceans at those oil extraction points Cheers

The sea level has been rising pretty steady for over 100 years. It can easily be compensated for by creating large man made lakes in low areas of the world. The central valley in California once had a lake as large as the Great Salt Lake, but it was destroyed by man. The Mississippi River floods nearly every year causing millions in damage. For less money we could build a large lake along the edge of the river that would eliminate the annual flooding and eliminate much of the sea level rise, Kill two birds with one stone. This would be environmentally very friendly, creating new habitat for bird species.

Actually the "real" cause of sea levels rising is land subsidance. You pump out billions of gallons of crude oil, it is like sucking on the straw in your malted milk.

Many other things cause land subsidance as well, such as ancient salt beds getting dissolved by subsurface waters.

Some of it is also just the crust settling down.

Of course there is no money in researching these expected events, no one would care then. However if you can make some plausible "scientific" explanation blaming man- then there is a great deal of money being pumped into that area by those who profit greatly from a motivated group of young people. Why, if you lay it on thick enough, and reward those who perpetuate the false notions- that young motivated group would be more than willing to surrender their rights and their livelyhoods "to save the planer" because it gives them a warm fuzzy feeling of accomplishment- they actually "did" something.

I suggest you read the book "I was an Ex Drug Pusher." The "science" that goes into drug approvals is discussed in that book by one who was on the inside- that same methodology is what goes on in acedemia. Professors do not keep tenure by being a good instructor- no, they must bring in money to the university- it is about profits, and professors keeping their jobs. Their students pay the price because only those who can parrot the prof get good grades.

But cite simple plain logic in a test or assignment in grade school or high school- forget- truth has no place in a dlassroom. The classroom is where you are to be indoctrinated into the new society. You are being socially engineered to believe the likes of Al Gore, even though he is lying through his teeth.

No, the sea is not rising, the notion of "waterworld" is just fanciful thinking.

Now, if you believe the earth is an absolutely closed system (it is not) but scientists want you to believe it is so thier theories stand up (they will not otherwise) then, just the simple byproducts of metabolism, one of which is water- would logically increase in volume just from the amount of life on this planet. But then, you are being conditioned to believe that the global population must be reduced- that is the ultimate goal of such "education". To get you to agree with failed logic of eugencists to eradicate the global population. Go read what Dr Pianca of UT Austin spoke about a few years ago, and yet his credentials are only as a herptologist.

Just because the UN is funding it should condemn it follow the money- because the rights you give up will be your own, you will never be of the decisionmaking circle.

Besides- there was a time when the seas were less saline, it is not the end of the earth if poles melt- it has happened numerous times before.

It's not a threat right now though, so instead of just 'investigating' we should come up with solutions. Right?

And holding true to alarmist form, omission may be your greatest asset. You also have areas along the equator and shallow ocean basins that do just the opposite.

Explore your own references in depth.

Big Gryph says "Well the land ice sheets of Greenland, the Permafrost in Russia, glaciers and Antarctic glaciers and submerged ice have all been melting at a rate faster than previously measured."

Even if you keep repeating the lie IT NEVER becomes the truth no matter how much you want it to.

I know "the model" is reality in your world, but in this world reality is reality.

I think groundwater has a big effect on the estimated sea level rise. The good news is that if we build more damns we can offset some of the effect. Building big huge damns is the environmentally friendly thing to do.

I live 941 ft above sea level so I don't really have to worry about it for a while. Suffer Bi****!

Oh yeah, you're going to get a lot of answers on this question! Or no, wait, this is the only one...and the best...right?

All the waste that is in the ocean.
