The Problem With Melting Polar Ice
PA Pundits International ^ | 22 February 2010 | TonyfromOz

Posted on 02/22/2010 7:00:42 AM PST by TonyfromOz

Climate Change/Global Warming believers accept by faith the most complex Science, but haven't they forgotten that basic Science we all learned in High School. Ice will not even begin to melt until it rises above 0C. (32F) If the temperature never gets that high, then the ice will never melt. The warmists accept as fact that the temperatures 'might' rise by as much as 5 degrees. This link, http://www.antarcticconnection.com/antarctic/weather/index.shtml shows Antarctic weather, and even in Summer, the mean average temperature only rises to Minus 15, and even though at some time during the day for short periods of time it may actually be above that 0C mark, it's never enough to melt significant levels of ice. What ice that does melt is around the edges, ice already in the ocean. Then, should not Archimedes Principle apply here, and any ice already IN the water cannot change the level of that water, even if it melts. Only 2% of Antarctica's total area is Sea Ice, as the other 98% is ice on the land mass, where temperatures never average higher than Minus 15C.

Dont confuse the issue with facts.

This argument works great for the North Pole, but not the South.

The only ice melted up there is by Todd Palin’s awesome snow machine!

Gore better get a few million more to substantiate his thus far failed assertion!

Gore is quite the poet, though (remember his little poem a few months ago which he read to the limousine liberals in Copenhagen?)

The thought of that poem is so bad I feel like I want to look at a picture of Helen Thomas just to feel better.

The only way to save the planet is to launch several million tons of tin foil into space and make a big tin umbrella over the arctic. We’ll have to use a big slingshot to launch the tin foil to avoid increasing the CO2 levels. We’ll need to have some experts in space to assemble the tin foil, so I suggest we start off by launching Al Gore and a some progressive liberals.

75% of the Antarctic ice pack is 8 meters thicker than it was 20 years ago!

This argument works great for the North Pole, but not the South.

Actually, since the 'ice that is on land' is mainly in the south pole, it works specifically for the south pole in that regard ... don't hear of any weather reports saying that area is forcasted to exceedn 32 degrees.

The local Fox weatherman just told us that the artic air mass is as cold as it was in the mid 1970s. So, we can expect the current lousy winter weather pattern to persist at least 3 more weeks.

I wonder how global warming explains a colder artic air mass?

“This argument works great for the North Pole, but not the South.”

Fortunately, the ice and snow in Antartica is actually growing - not melting.

Exactly why do you say that this arguement does not work for the South Pole?

The South Pole's Ice sheet is mainly on land--not in the water like the North Pole.

However, as several other posters have already observed, the South's Ice is growing, and we don't have to worry about it anyway.

The author may have wanted to take a science class beyond high school. He apparently is is unfamiliar with the process of sublimation whereby a solid is converted into a gas without an intervening liquid state. For water ice, this process can occur at temperatures far below freezing if proper vapor pressure conditions are in place. What drives the process is heat (not to be confused with temperature). The water vapor lost through sublimation is carried into the atmosphere where it moves along through the hydrologic cycle. I curse sublimation when I'm ready for a frosty gin and tonnie and the ice cubes in the tray are nothing but little nubbins. Anyway, if the author wants to sound even reasonably intelligent, he should probably bone up on a little basic science.

The important point here is not whether the ice is growing or shrinking. The critical factor is the water content in any given volume of ice. All ices are not created equal.

I dont agree with it, but the warmists argument is that the Greenland ice sheet is most suceptable. The argument is that when the edges of Greenland are exposed then the darker rocks are exposed. Sunlight hitting darker rocks will warm the rocks above 32F and will thus cause the adjacent ice to melt. This is referred to as “forcing”.

I disagree with this forcing because it only takes one cold winter to stop the process. And we are in the middle of an Artic Oscillation, in which Greenland has been re-covered with snow and ice.

Secondly, the Greenland ice sheet is only a fraction of the Anarctic ice sheet.

Thirdly, this scientist provides pretty good details on how complicated sea level changes are, the fraud associated with reports of sea level changes and how there is no evidence of human influence: http://www.climatechangefacts.info/ClimateChangeDocuments/NilsAxelMornerinterview.pdf

Another science fact-the 32ºF temperature, the “freezing point” is actually the point at which a given volume of water is as frozen as it is liquid, IOW, it is (oversimplified) 50% solid. Freezing starts at 37ºF and by about 28ºF it should be solid. Now if there is any sea water in the mix, well, that skews temps downward. Sea water frezzes at closer to 28ºF.
