An example of possible factors that contribute to north pole ice cap melting

[Raccoon1010]

I did a search about the composition of the north pole ice cap. I started thinking what is the density between ice and water itself without any other materials in the solution. And the search said that ice has a density of 917 kg/m^3 while water is 1,000 kg/m^3. And we should all know from highschool chemistry class or science class that water expands to form crystaline ice which is the liquid to solid phase of water (H2O). I am aware and some people are too that there are two major oceans that we think about which are the pacific and atlantic oceans. And we all know that salt ratios in water affect the melting point of ice.

"The water-based composition around the North Pole ice cap is primarily sea ice, which is essentially frozen seawater containing salt, with the majority of the ice mass being composed of freshwater ice, with small amounts of trapped brine (saltwater) pockets within the ice crystals; this ice is constantly forming, melting, and moving due to ocean currents and wind patterns."

And then I started wondering about the various factors that would be involved in polar ice melting. And some of the factors I came up with was kinetic energies from the solar radiation as well as the permeation of radiation including heat out of the atmosphere and back into space. Salt and other chemicals may change the melting point of ice. And we all know that during snow season many of us sprinkle some "rock salt" on the driveway and it slowly melts.

Just how salty is the water in the ocean? Well fellas, if you tried to survive on it you would probably meet of demised fate. It must be de-salinated first and there are different methods for doing that. I've heard you can take a pot of boiling salt water from the ocean and then put a glass at an angle with the corner facing down towards a cup and it will collect condensation from the steam onto the glass and flow into the cup. Here is another article coming from other areas of the world:

Now I don't know about you ladies, but I do know that saline water flowing in and around the polar ice caps may have a melting affect which includes but may not be limited to: warmth of the ocean waters as well as chemical additions to the water including salt. Like rock salt on the driveway slowling melting the snow.

Regarding the previous post, I wonder how much rain and snow actually created that polar ice cap? Rain the snow would probably not contain salts, FYI. I do know that the water that is in the ocean really is quite liquid. And that polar ice cap really is quite frozen. Quite a difference in states of water and some with salts.

It's a thinking lesson in the areas of physics perhaps, chemistry, and other areas of science.

Now the two factors I described that relate to polar ice cap melting are water temperature and water salt levels. I think they said in the NASA article which is some information, that the boundary of the ice cap shape is receding. Meaning that liquid water is exchanging with the solid ice and interacting with it in such a way that it melts.

I need to do some looking into top of the polar ice cap melting due to air temperatures.

I also am aware of changes over time which could extend beyond recorded history as to the fluctuations in the ice cap size. I wondered if it was like a storage area, similar to an electric capacitor and how it stores electrons. I wondered if the ice cap shrinks for so many years and then later expands. I know there is some concern and I really don't want to alarm people that are prone to being alarmed easily as us Christians have faith in God and the bible and it's historical accounts. I think that the ice cap naturally goes thru normal changes in time anyways. We have emissions from sources that are man made. And then we have natural emissions from animal and other sources.

If you want to do a good estimate on sea level rise (which I suspect is dramatically overstated) you could check the oceans surface area and the volume of receding polar ice cap fluid to see how much volume would end up in the oceans. That volume must be distributed over that massive ocean area and it will probably not rise much do to ratios that are different between ice volume and ocean area.
