Experiment in Sea Level Rise
Will sea level rise if the polar caps melt?
Get a container. A tall one will work, like a tumbler. Fill it about 3/4 full with tap water. Add ice until the container is full but not so much that the container overflows or the ice protrudes above the top. Place a cover over the container to minimize evaporation, a saucer will do. Place the container on a table and mark the side of it where the water level appears. Make sure to choose the flattest part of the meniscus away from any ice contact with the wall. Let the ice melt. Once the ice is completely melted, check the new water level. Tell me again why sea level will rise? Well, the south polar caps and other glaciers are on land, you say? What is the volume of the ice on land, precisely? What is the relative proportion of that volume of ice to the total volume of liquid water in the oceans? What is the precise total surface area of the oceans? When that 'precise' volume of ice is spread over the surface area of the oceans how thick will it be? If you cannot answer these questions Al Gore, you cannot predict sea level rise. |

Estimates range from 60 centimeters to 60 meters, that's a hell of a lot of margin of error. This is basic high school algebra - do your own homework. The numbers are clear enough from a combination of remote sensing and direct bore hole surveys. Roughly 2km thick ice over most of Antarctica except for a few dry bits where there is arid dry desert. A similar chunk of deep ice but not as big sits on Greenlands interior. If all the ice on the planet were to melt then you get a 60-70m sea rise. This is an incredibly unlikely scenario. Although working it out has been a school geography excercise for a very long time. The most likely sea level rise over the next century is predicted to be somewhere in the range of 0.4m (IPCC) to 1m+-0.3m based on more recent observational data about how the ice sheets are behaving. eg. http://planetearth.nerc.ac.uk/news/story.aspx?id=293 Most of it coming from expansion. The additional contribution from ice melting is thought to account for roughly 30% of the observed rise. Regards, Martin Brown |

The sea is 3.5% salt dissloved in water. The displacement of ice is less than the volume it will occupy as liquid water. It will rise slightly. Floating sea ice is *pure* water frozen and displaces its own *WEIGHT* of the denser cold brine. When the ice melts and mixes with a typically 3.5% total dissovled solids sea water at 0C. The increase in the total volume of the water ice when melted and mixed with salty *sea* water in the oceans is about 3%. Part of the rise in sea level comes from expansion of the water that is already in the oceans as it warms up. Well, the south polar caps and other glaciers are on land, you say? What is the volume of the ice on land, precisely? What is the relative proportion of that volume of ice to the total volume of liquid water in the oceans? What is the precise total surface area of the oceans? When that 'precise' volume of ice is spread over the surface area of the oceans how thick will it be? If you cannot answer these questions Al Gore, you cannot predict sea level rise. These numbers are standard high school calculations. It was fun to see how little of the UK would be above sealevel if the entire polar cap ice was melted. Never occurred to me or anyone else at the time that the practical implications of this calculation might one day be important. You don't need to be all that accurate to get an answer good to the nearest 10m which is plenty good enough for planning purposes. The number is somewhere between 60-70m depending on whether you include the Greenland ice sheet and minor glaciers around the world. You done gone and annoyed the leftist weenies again ;-) Amazing just quite how wilfully ignorant you are. Regards, Martin Brown |

Tell me again why sea level will rise? Because "dittohead science" is a pack of lies. Your experiment is fundamentally flawed. The sea is 3.5% salt dissloved in water. The displacement of ice is less than the volume it will occupy as liquid water. It will rise slightly. Floating sea ice is *pure* water frozen and displaces its own *WEIGHT* of the denser cold brine. When the ice melts and mixes with a typically 3.5% total dissovled solids sea water at 0C. The increase in the total volume of the water ice when melted and mixed with salty *sea* water in the oceans is about 3%. Part of the rise in sea level comes from expansion of the water that is already in the oceans as it warms up. Well, the south polar caps and other glaciers are on land, you say? What is the volume of the ice on land, precisely? What is the relative proportion of that volume of ice to the total volume of liquid water in the oceans? What is the precise total surface area of the oceans? When that 'precise' volume of ice is spread over the surface area of the oceans how thick will it be? If you cannot answer these questions Al Gore, you cannot predict sea level rise. These numbers are standard high school calculations. It was fun to see how little of the UK would be above sealevel if the entire polar cap ice was melted. Never occurred to me or anyone else at the time that the practical implications of this calculation might one day be important. You don't need to be all that accurate to get an answer good to the nearest 10m which is plenty good enough for planning purposes. The number is somewhere between 60-70m depending on whether you include the Greenland ice sheet and minor glaciers around the world. You done gone and annoyed the leftist weenies again ;-) Amazing just quite how wilfully ignorant you are. Regards, Martin Brown Not that there isn't a lot of willful ignorance on the left.

You mean the surface water, of course, since only the first 50 meters or so is very warm or sees enough light to get warmed by the sun. The other 3000 meters of depth are closer to -2 or -3 C except where thermal vents heat it to 600 C at the deep ocean trenches. |

Experiment in Sea Level Rise
"Geoff" wrote in message ... Will sea level rise if the polar caps melt? Get a container. A tall one will work, like a tumbler. Fill it about 3/4 full with tap water. Add ice until the container is full but not so much that the container overflows or the ice protrudes above the top. Place a cover over the container to minimize evaporation, a saucer will do. Place the container on a table and mark the side of it where the water level appears. Make sure to choose the flattest part of the meniscus away from any ice contact with the wall. Let the ice melt. Once the ice is completely melted, check the new water level. Tell me again why sea level will rise? Well, the south polar caps and other glaciers are on land, you say? What is the volume of the ice on land, precisely? What is the relative proportion of that volume of ice to the total volume of liquid water in the oceans? What is the precise total surface area of the oceans? When that 'precise' volume of ice is spread over the surface area of the oceans how thick will it be? If you cannot answer these questions Al Gore, you cannot predict sea level rise. The sea level isn't rising - the land is sinking into the space vacated by all the coal & oil. |

There are places where the ground water level is being depleted by seven FEET a year. |
