The Problem With Melting Polar Ice

Posted on Mon 02/22/2010 by


Have you ever noticed something about those ordinary average everyday people who believe in Climate Change/Global Warming?

Without question, they will believe the most complex Science they are told about, taking it on faith alone, without understanding the first thing about it. Their belief is that if a Scientist says it, then it must be true. Then, if a ‘Celebrity’ repeats it, then that adds further credence to it.

However, they all seem to forget to ask the most basic of questions, that of something they themselves actually did learn in High School Science, saw proved before their very eyes, and know absolutely as proof.

The two things that stand out the most that should be asked is about the melting point of ice, and the question of Archimedes Principle.

This story is just one of many in most sections of the media that has recently come out. It says that Climate Scientists have now withdrawn from earlier claims of rising sea levels. For so long we have have been bombarded with Science telling us unequivocally that the Polar Ice Caps are melting and that melting ice will cause sea levels to rise. The level of that rise has sometimes differed outrageously, with some sources saying it could be up to 100 metres, and some saying it may be only 6 inches or so. The time this rise will engulf us all is also something of conjecture, with some sources saying ‘soon’, and some saying by the end of this Century. However, the main thrust is that the original premise is that sea levels will inexorably rise. That’s a ‘given’, so we are told.

However, now it seems Scientists are beginning to back pedal.

I’m not going to talk about complex Science here. I will however mention two simple facts all of us learned at High School during those Science lessons, things that nearly all of us have forgotten.


Water exists in three states, that of a solid, a liquid and a gas. Water exists in its natural state as water, because all around us, the temperature range is within that temperature where it does not freeze, or does not boil. The gaseous state is water vapour or steam. As soon as water reaches 100C (212F) it changes from a liquid to its gaseous state, that of water vapour, steam. Water freezes to its solid state, ice, at 0C, (32F) and, as long as the temperature stays below that level, then it will stay as ice. If the temperature rises, then it has to rise above that 0C before it starts to turn back into a liquid, and then the ice will gradually diminish until it has all been turned to its ‘normal’ state, that of water.

Now I want you to visit the site at this link, which shows the temperatures in Antarctica.

Right at the top there it shows the ‘Mean Temperatures’. (Average) In Winter the average ranges between Minus 40C and Minus 70C. Even in Summer, the average range is between Minus 15C and Minus 35C.

So, even at the height of the Summer in Antarctica, the temperature never reaches that 0C when ice will ‘begin’ to revert slowly over time to its liquid state. For that ice to reach that temperature, then something pretty drastic would need to happen with the temperature there. We are told that there will be a rise in temperatures over the next 50 to 100 years, and again, this is something most of us take on faith. That temperature rise varies between 2 and 5 degrees C, that 5C being the upper mark, but most quotes are around that level of a 2C rise in temperature. Even if the temperature rose by the worst case scenario, that of 5C, then the mean temperature would still be well below 0C, that point where ice will begin to change to a liquid state. If that 5C rise was to occur, then the highest average temperature reached in Mid Summer in the Antarctica would still be Minus 10C, well below that point where the ice melts. This is not isolated areas where the temperature at the height of Summer might creep slightly above that 0C. (32F)

Now, some of you might think this may be a pretty convenient argument, because the ice that is supposedly melting is around the edges, where that ice is actually sitting in the seawater, and where the air temperatures might actually be above that 0C. No matter really, because if that ice is sitting in the water, then that seawater is actually above 0C, so that would aid the ice in its reversion back to water by heat transfer from the seawater to the ice. So that sea ice is actually at a level where it is above 0C, and that is where the second part of High School Science comes into play.


Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

This is not complex Science. We’ve all seen it so often that it has become second nature to us all,  so much so that we have actually forgotten the why of it. You can do this simple experiment yourself at home, and how many times has this been done by all of us without even thinking about it.

Fill a large glass with ice cubes, and then fill the glass almost to the top with any liquid, be it water or a soft drink of your choice, and then check the level of that liquid line at the top. Then just leave it. Come back later after the ice has all melted, and that liquid line is the same as it was when the ice was in the glass. The melting ice has not caused the liquid in the glass to flow over the top of the glass.

The same applies to sea ice.

The iceberg that the Titanic hit in 1912 was four times the size of that ocean liner. If you could find one million floating bergs the size of this and tow them to the equator, and then stick around and watch them as they melt, they will not raise the level of the ocean the tiniest fraction of an inch.

All the ice that we are told is melting is around the edges of Antarctica, and also in the Ocean, (again, something most of us take on absolute faith) and this ice is ice that is already in the surrounding Oceans.

So, using Archimedes Principle, then there could be a billion tons or even ten to a hundred times that weight of sea ice, and if every last piece of that sea ice were to melt, then the levels of the Oceans around the World would not rise by even that tiniest fraction of an inch.

What might actually cause the sea levels to rise is if the Ice actually ON the Continent of Antarctica were to melt, and melt in significant proportions. However, as shown at the link, those mean average temperatures on Continental Antarctica will never reach the point where they will begin to revert from ice to the liquid state, water, even if the worst case scenario were to occur with respect to temperature rise. That ice is also not like your small average ice cubes in a glass, or even the size of a Titanic sized iceberg that might melt over a period of months as it moves into considerably warmer water. At its thickest, the ice on the Antarctic Continental land mass is nearly 16,000 feet thick, (that’s all just ice) and even the top fraction of that cannot melt, as it never even approaches 0C. What also needs to be mentioned, and even highlighted in bold is that the land mass of the Continent of Antarctica is 98% of the size of all Antarctica, so only 2% of that ice is actually IN the surrounding Ocean, where that water is still only slightly above 0C, and not by very much, as during Winter, even that Sea freezes up.

Take that above link again, and read what is shown there very carefully.

Ice that is always at a temperature level below 0C will never even begin to turn to water.

Sea Ice is already IN the World’s Oceans, and it cannot cause sea levels to rise.

Al Gore is an absolute genius. He has succeeded in turning all his believers brains to mush. He asks them to take the complex Science on faith, and then succeeds absolutely in making us forget simple High School Science.
