During this Global warming, if all the ice burgs melted, how far under water would Miami be?

Ice burgs melting wouldn't raise the sea level.  It's the ice on land melting that adds to the ocean.  Miami, and most of Florida would be something like 15-20 feet under water if all the ice melted.

I think it's gonna be real cold.  Like Michigan (where i live).  But no, If it is in fact a ice age, that means that  huge amounts of water  are frozen into glaciers (and because we only have so much water on earth) sea levels will actually go down because water is locked in the glaciers.  Global warming causes glaciers to melt and hence rises sea level.  And by the way, we are still technically in an ice age (we still have huge ice sheets) we are in what's known as an inter-glacial period.  The last glacial maximum was about 22,000 years ago.  Sea levels were so low that humans could walk across dry land from Ireland to Britain then to the mainland of Europe! Check out a map!

Short answer: nothing would happen.\n\nLonger answer:  Think of it like this.  The oceans make up 2/3rds of the surface area of the planet, approximately.  They are much, much deeper than tall buildings, trees, or even mountains.  Also think about water displacement- the volume of water that something displaces is equal to its own volume.\n\nRising sea levels are caused, mostly, by melting polar ice caps.  So how big are these ice caps and how much is melting?  The ice caps cover the Arctic (the size of a major continent) and most of Antarctica, which together is probably the size of two major continents.  Worst case scenario- most of it melts.  Let's be optimistic- 10%.  Can you really imagine the boats that we have adding up to 10% the volume of an entire continent, let alone two?  No, it's ridiculous.  A mountain or two, sure, plausible, but something the size of Texas?  No.  Absolutely not.

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.

Here are some cool facts...\n\n~Antarctica is actually a desert, receiving about the same precipitation (less than 2 inches a year), as the Sahara Desert. \n\n~Dogs have been banned from Antarctica to protect the seal population. \n\n~If Antarctica were to melt, the sea level would rise over 200 feet. \n\nHere are some links that have more...

How far below?\n\nWater has quite a high thermal conductivity value.  Depressing the freezing point can be obtained by adding a salt, such as table salt (sodium chloride) or even calcium chloride.  Maple Leaf Gardens (the old NHL hockey arena in Toronto, Ontario) use to use a brine (salt water) solution in the cooling system to keep the ice frozen.\n\nIf you weren't worried about corrosion, you could try a brine (saturated salt solution) in your cooling system.  Water has a thermal conductivity of approximately k=5 to 6 mW/cm/K (relative to carbon tetrachloride or toluene being close to 1 and still able to go well below 0C/32F and remain liquid).  (CRC Handbook of Physics and Chemistry...do your own unit conversions)\n\nDon't let the brine leak though....

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.

all living beings would die.  Too much to hydrate not enough water.

Not quite right.  It is most dense at 4 degrees C.  If it didn't, the water would freeze from the bottom up.  As it approaches 0 degrees, it becomes less dense and rises above the more dense warmer water and freezes on the surface and goes down.  Otherwise, fish would be on top of the ice and die after it froze.

definitely. it's practically the one part of global warming scientists agree on.\nover the next century, we will see the oceans warming and thus expanding (sadly flooding places like Venice), also the polar ice caps melting (once again, not good. they keep the earth cool...see a vicious cycle?), not to mention serious climate change and animals migrating to the north to keep cool. it's already happening...yikes!

Salt, NaCl, turns into Na+ and Cl- ions in water.\n\nThe ions changes the equilbrium of H2O melting and freezing.\nLiquid water is block by the ions, so it has a harder time freezing back onto the ice. Since the ions doenst slow down\nthe melting of ice, but slows down the freeze of water.\nThe ice now melts at below 0 degree.\n\nSo a normal ice water will be at zero degree.\nBut a salt put on the ice/water will melt more of the ice at a lower temp., about 7-10 degree colder, depenting on the ammount of salt and ice avalibale.

All the water in the atmosphere would cover only about an inch  of the ground (First Link). If the South Pole Melted the sea levels would rise 200 ft, and if Greenland melted they would rise another 20 ft, If the North Pole melted sea levels would not be affected as it already displaces an amount of water equal to it's weight, because it floats (second link). All other water sources are negligible. So basically I wouldn't even get my feet wet in Dallas (around 700-800 ft above sea level).\n\nThe third link provided has a fairly comprehensive look at reasons the flood of Noah's time was impossible (see parts 5 and on). If you want to believe in Noah's flood you have to realize that it would have had to been completely supernatural, and afterwards God (or satan if you will) planted evidence to confuse us.\n\nThank you Jesus my lord and savior.

The water level will neither go up nor down.\nSuppose we have an ice cube of mass m floating in the water. In equilibrium, it will have to displace enough water to support its weight. It is V=m/d\nNext when the ice has melted, it turns into water of volume: V= m/d! exactly the same volume as it displaced before. So the added volume is the same, so the level of the water will not change.

The density of seawater:\n\nhttp://hypertextbook.com/facts/2002/EdwardLaValley.shtml\n\nThe density of ice:\n\nhttp://www.elmhurst.edu/~chm/vchembook/122Adensityice.html\n\nThe figures for the world's volume of freshwater are available on a number of sites and in various texts.  Suffice to say that about 97% of the world's water is oceanwater, and some 80-90% of what's left over is frozen in the ice sheets.\n\n''With ice being significantly less dense than water will melted glaciers and ice mass really cause the ocean to rise? And even if that is so, would the volume of ice melting have to be incredibly dramatic to cause even a small rise?''\n\nDefinitely.  Sea ice will not contribute to rising sea level, but ice sequestered in glaciers will, because it was ultimately derived from the ocean.  The volume of melting would not have to be dramatic to make life interesting; if Greenland alone melted, that would raise sea level by some 20 feet.  A much smaller rise over the next century, of one to three feet, would still be disastrous for the most low-lying areas of the globe.

No, it isn't 33 degrees F.  At 32 degrees (definition 0 degrees Celsius, 273 degrees K) and at one atmosphere of pressure, water and ice coexist; this is the melting point of ice.  \nIf the water is not pure, the melting point is lower than previously stated (freezing point lowering is a colligative property).

Ice is less compact or less dense than liquid water.

That's a real tough question to answer.\n\nHurricanes don't just result from warm water. If they did we would expect to see more hurricanes in tropical regions than we do. It's fairly complex, but to form hurricanes basically need warm water under a stable, cold, upper level air mass to produce the low pressure bubble. Cyclones and hurricanes only form in a few regions around the world called 'cyclone basins' because only a few regions have those exact conditions. Because the conditions for hurricane formation are so specific it's really hard to predict the effects of climate change.\n\nWarmer oceans should increase the frequency and intensity of hurricanes. Howevere the atmosphere and oceans probably don't warm at the same rate. The atmopshere ATM seems to be warming much faster than the oceans. That might mean that the cold summer air masses needed for hurricane formation will become much rarer, and as a result hurricanes may become far less freqeunt. \n\nAlternatively the cyclone basins may just move. With moderately warmer oceans and a much warmer atmopshere the basins might well move to higher latitudes to where the air is colder. That would be far more catastrophic than a simple increase in frequency. Places that are historically hurricane prone have learned to build to cope with them. If the basins move hurricanes will start stiking places that are not deisgned to withstand them. Can you imagine the effect of a hurricane on New York City or London?\n\nThen we get to throw in other complicating factors like the changes in ocean currents and atmopspheric systems brought about by warming. Weather is the ultimate choatic system, there are a huge number of interscting variables. That makes it just about imposisble to predict 3 months in advance under stable conditions. Trying to predict what will happen 30 years down the track under changing condition is laughable.\n\nAt the moment there is just to much we don't know about how hurricanes form and what the effects of global warming will be. The majority opinion is we'll see more hurricanes and more intense hurricanes, but there is a large minority plumping for movement inthe cyclone basins and a small minoirty predicting decreased frequency.\n_________________\n\n>>>>watch the movie "The day after tomorrow". good movie,\n>>>> and accurate prediction of what could happen if global \n>>>> warming continues.\n\nPMSL. \n\nYeah, and after that watch "Godzilla" for an accurate prediction of what happens following an atomic test.
