Scientists studying the changing nature of the Earth's climate say they have completed one crucial task - proving beyond a doubt that global warming is real.

Some estimate that the melting of the Greenland ice sheet could raise sea levels as much as 6 to 7 meters - or perhaps you'd prefer to say ONLY 6,000 to 7,000 millimeters. As well, unless your calculations come from FOX news pundits or Discovery Institute young Earthers one has to consider that the melting of that one ice sheet is not be the only land mass on the globe where ancient ice is melting.
And yet when you do the math yourself you will discover that those estimates were way off. While the amount of ice seems to be massive, yet when you compare it to the volume of the world's oceans you will notice it isn't nothing but a drop in the bucket. That the amount of water trapped in the Greenland Ice Sheet isn't enough to cause the rise that some estimate.

Oh, remember when doing your calculations that when water freezes it expands. Which means that the volume of ice in Greenland will equal less water. I even included a few links to help you get started. Of course your numbers might be a little off if you don't include shore line gradient so I included that link as well.

The volume of ice on land versus the mass of melt water in the oceans? If you want to continue with this line of argument, we can also discuss how the volume of water increases with temperature, and how ocean currents are also affected by water temperature and density.
Back to the question of the Greenland ice sheet and sea level rise. I direct you to YOUR OWN LINK.

And you didn't do the math yourself. Could it be that you are afraid that when you do you will discover that the estimate on that fact sheet isn't a fact but fiction. Or did you run the numbers and discover that the truth is that the rise is less than a couple of millimeters.

Time to try thinking for yourself instead of getting thoughts that support your beliefs. Find out the truth for yourself by doing the math yourself. Also notice after many of those estimate were discovered to be wrong that they had to trot out thermal expansion which fell flat when math proved that for the amount of heat needed the land would all be barren with every creature on the land well cooked.

Your Physlink link is irrelevant. As was previously pointed out, the volume or ice on land does not in any way decrease the volume of meltwater that reaches the oceans. Your feeble attempts at deflection are akin to the old riddle, "Which is heavier, a ton of lead or a ton of feathers?" (FYI, Tina - don't bother to look it up. A ton is a ton, they weigh the same.)

Your Duke link is irrelevant. How waves behave on or at coastal rise has NOTHING to do with global warming.

Your Hypertextbook link points out that there is over 4 times as much water locked up in ice than in ALL OTHER NON-OCEANIC WATER SOURCES COMBINED.

In other words it is an inconvient truth that you need to avoid. Dispite the fact that it is proven fact that water when freezing expands, that ice floats as the result of that expansion. That you could fill a glass with ice and then water all the way to the rim. Come back later and you will discover the level of water has gone down.

Again, I quoted DIRECTLY from the factsheet YOU provided. Personally, I question the math that the Greenland ice sheet alone contains enough water to raise sea levels 20 feet over an area of 140,000,000 square miles. However, I do not at all find it difficult to believe that the current trend of GLOBAL ice loss can raise sea levels to a degree that would inundate large areas of coastal settlement.

Your discussion with me has not been about sea ice, but about glacial ice. Please stop insulting yourself by not recognizing the difference.
As for your experiment with displacement of water, the correct analogy here would be to suspend an ice cube over a glass of water and see how much higher the level rises as the cube melts.

Both an 8.35 lb block of ice and an 8.35 lb block of styrofoam will displace the same amount of water (1 gallon) and still, this is irrelevant to glacial melt.

OK.
Volume of ice in Greenland ice sheet: 2.85x10^15m^3.
Area of oceans: 3.35x10^14m^2.
If all the ice melts, you get 2.85x10^15/3.35x10^14 = 8.5m sea level rise, not taking into account extra land swallowed up.

Don't quote, calculate. Do the math yourself, think for yourself. That is if you can. Instead of quoting others who are wrong you should do the calculations and quote yourself instead of quoting predictions that are obviously wrong after only a few years.

Yet a 8.35 block of ice will occupy less volume and a equal weight in water will occupy even less volume.

The question discuss is about volume not mass. And the fact is that phyics has already proved that a gallon's worth of frozen water will not occupy the same volume once it returns to a liquid form.

If I am wrong then show me a creditable source that proves that an equal mass of water will occupy the same amount of volume in both the solid and liquid state. I managed to find one creditable link that proves me right.

You make demands that you can't answer your---self. When are you going to answer that eight grade question? See why your a Less than a Box of Rocks.Oh asking what the question was and asking me to answer it for you is old and dosen't support your useless babble.

Not bad, but you left off shore line gradient. Of course others did the same numbers and arrived at a much different answer. Which is why thermal expansion was offered. It failed when they missed how much heat would be required to heat that mass of water. They also missed the effect of evaporation as the result of the increased surface area and warmer air. Some of which would not return to the ocean but end up filtering into aquafir or even end up sitting in a bottle on a store shelf.

They have sense added Antartic ice mass to the latest attempt.

Gallon's worth would represent more than one. What is PHYICS?

Would you take my word if I just said it was so. Somehow I doubt it and your friend would doubt it even with the link.

As for the math, I did do it myself, and I noticed that even with you demanding I do so that you did not. Care to lead by example?
