Melting Icebergs etc = Sea level rises.?

Dear Sir:\n\nYes, you have all the facts correct in your mind...\n\nWhat I see that you haven't got a good grip on is the \nsize of the problem.\n\nThe glaciers that the scientists are talking about extend for hundreds and hundreds of miles, and they are solid ice. They are presently sitting on solid ground and moving towards the water in a slow march, maybe 5 feet per day. These huge masses of ice are hundreds of feet high. So, the water they contain is just a massive amount of liquid when it melts. The terms gallons or liters is not applied to liquid in that huge of a mass. Terms like cubic miles is probably more appropriate. So when you talk about adding 2,000,000 cubic miles of water to the seas, some real changes in water level will probably result.\n\nIn the USA, a lot of homes and businesses are located at places where the elevation above the current sea level marks are only 1 to 3 feet.  High winds or storm surges could endanger places even higher up than that. In the area around New Orleans, La., the city is actually below sea level and is dry only because of a huge system of dikes that actually failed in a recent hurricane. As a result the city of New Orleans and much of the surrounding towns went under water.  Rebuilding, Clean-up, and repopulation could only begin after the waters receeded to their normal levels and the dikes were repaired, pumps placed back into service to clear out water behind the dikes, etc. \n\nWhat the scientists are suggesting is that in the future these flood waters might not receed...they will just stay there, and the flooded areas will stay flooded from now on...WOW.  That is a doozie to think about.

You take all the temperatures across the globe and average them out and compare to the same day and time every year and when the average is steadily getting higher, like it is, its called global warming.\n\nThe ice caps start to melt, sea level rises, climate changes.  Just a whole lot of fun stuff like that.

There are theories about a new ice age created by a magnetic reversal of the poles. Polar ice caps melting is bad, but there is no impending doom. If you feel so strongly about this you should get started on your ark.

I'm not sure if the sea level rise is that dramatic. There are a lot of different predictions being bandied about. The estimate from the telegraph is that there will be a 20ft rise by 2600. The rise this century is expected to be about 1m.

First off:  There are no magnetic anomalies in the Devil's Triangle.\n\nFor something to raise global sea levels by 300 feet, it would need to have a volume of 1.07 x 10^17 cubic meters.  A spherical meteor that size would be 355 miles across.  I think someone might have noticed something like that.

why not get a pipe from the bottom of the ocean to space and pump water into space to save the sea level rising. a few boats aint gonna help

When ocean levels rise the water must go somewhere.  So, the water covers up land.  Thus, if ice caps in the artic melt many of our coastal areas will eventually be covered in water... including New York, Boston, etc.

i believe that it will be awful with global warming and everything. it will get warmer which means that sea levels will rise.but people will invent all sorts of new things to stop that from happening people might also be able to live longer because of all the medicines.

The weather changes will have already happened if they're enough to make the icebergs melt.  \n\nRaising the temperature of the earth 8 degrees, sea levels will rise, flooding coastal areas. Heat waves will be more frequent and more intense. Droughts and wildfires will occur more often. Disease-carrying mosquitoes will expand their range. And species will be pushed to extinction.\n\nMore and more intense rainstorms and hurricanes.  Sea level rise will result in loss of coastal wetlands and barrier islands, and a greater risk of flooding in coastal communities.

The Pacific and Atlantic Oceans have different heights with the highest sea surface in the Western Pacific. But don't worry about all that Pacific water rushing into the Atlantic and flooding the Texas coast.\n\nAs far as equalizing levels, this has occurred but introduces an idea that many people find hard to imagine. The difference in heights is a result of a "dynamic equilibrium". Dynamic means changing, but equilibrium means balance, which we usually think of as no change. How can this be? Think of an unchanging balance as one like you can find on a scale where you place the same weight on both sides and it will balance -- always and forever. There is no new weight added or removed, no energy added or removed. This is Static equilibrium, an unchanging balance. A dynamic equilibrium involves the balance of changes. Imagine on your scale that you have cups instead of weights. Each cup the same size and is being dripped into and overflows but it will still balance if the fluid dripping in and out balances on both sides. Here there is a dynamic equilibrium with changes in mass or weight. If we want to imagine an equilibrium that also includes energy, let's have one side of the scale have a smaller cup than the other. Water drips in and overflows, but the two sides can never balance because the two cups can never hold the same amount of water. This gets a little complicated, so hang in there. The cups can't balance each other with weight alone. The lighter cup will go up and the heavy cup will go down. You can make a dynamic equilibrium by pushing down on the lighter cup. Now you have two cups with different amounts of water that balance. Hmmm? This can only happen with the addition of energy.\n\nThis is similar to how the sea surface heights can be different -- there is a dynamic equilibrium. It is indeed affected by the rotation of the Earth which is where some of the energy used to maintain the balance comes from. More comes from the Sun and its heat. The energy acts through winds on the sea surface and currents which tend to cause water to "pile up" where currents are swift. Imagine the surface of your morning juice in its cup. If you swirl that juice, the surface is no longer 'level' but slanted (and the slant rotates with the swirl). This slant is maintained as long as you continue to swirl the cup. You have an equilibrium that requires energy. The moment you stop adding energy by swirling, the surface of the juice levels out. It is now a static system with a static equilibrium that is simple to understand.\n\nThere is a huge science project (yes, scientists do science projects too) called TOPEX/Poseidon that looks at the sea surface (and other ocean information) from orbiting satellites. And there are oceanographers who specialize in studying the sea surface and what causes it to be different from flat. Some of this information is available on the Internet including really cool pictures made from satellite information.

When the ice was floating on water, the water had lifted by certain level..tht level was equal to the weight of the ice..s when the ice melts , the water level wont increase since the water from icemelt is equal to the earlier weight of the ice ...and the water on which ice was floating had already risen to accomadate tht weight..so it wont rise again when the ice melts...

The iceberg has more potential energy, because there is so much mass being held off the ground. (That energy comes from "frustrated gravity," which is pulling down but not bringing the ice any closer.)\n\nThe flame and match has more active energy, which means that it will RUN OUT of energy sooner than the iceberg will.

The artic ice shelf IS melting .Not a myth .Polar bears ARE drowning .Artic communities have experienced increased flooding and evacs.Worst droughts out west since the thirties.There is abundant evidence of glaciers retreating.The science is out there and I will believe scientific evidence and experience  over people who want to bury their heads in the sand and stupidly do nothing any day of the week.Don't let yourself get conned by people who are in denial and have no proof of their own to contradict scientific evidence and eyewitness accounts .Global warming is no joke and we must do something to prevent it from getting worse now before it's too late.

Our earth is warming due to the excessive use of fossile fuels and the thinning of the ozone layer that surrounds the earth. As the ozone layer thins, more UV rays can come in, the temperatures are warmer and this caused the melting of the polar ice caps. As they melt, that changes the temperature in the water currents and raises the water level. Because everything interacts in life, it can eventually change the surface of the earth, cause certain species to become extinct because their habitat changes, and will raise the temperature over the earth. This is not something that will happen overnight, but because it's been happening for years and is getting worse, it's a serious concern with scientists. Unfortunately, it's not much of a concern for our oil loving president and his administration.

The earth is protected by the Ozone Layer, which helps us from the sun's damaging uv rays.  As people pollute the air, the ozone layer becomes damaged and evenutally will diminish causing the sun's damaging rays to enter the earth's atmosphere increasing temperatures.  The increase in temperature would cause areas of extremely cold temperature where icebergs are found to become warmer; thus causing icebergs to begin melting.  The increase in temperature will also cause many of the plants that survive and grow in the tropics to die.\n\nAir pollution contribuites to GW by causing the ozone layer to dissapear, leaving sections of "holes" where the powerful ray's of the sun will cause increase in temperatures damaging life forms to include plants, animals that survive on such plants, polar caps melting which could affect the animals (polar bears, penguins, etc).

What are you asking. Sea level is always the same.\n\nYou mean elevation above sea level? I think the average is zero, or so I've heard.

It will, in my opinion, but you shouldn't worry about it because it'd take toooo many years to melt all those huge icebergs&co. Salt? Hmm...we'd never taste salt for quite a few years should they use it to stop the floods. What about icers? That shd work...
