Now, if you have all this very cold, nearly freezing water surrounding these ice caps, sucking up carbon dioxide out of the polar atmosphere, at nearly the highest possible rate, 30 times faster than oxygen, and 70 times faster than nitrogen, doesn't it stand to reason that the air that remains might just have a lot less carbon dioxide in it than the atmosphere across the rest of the planet?

The planet today is dry and barren, with most of its water locked up in the polar ice caps.

The rise of CO2 from 270ppm to now over 400ppm, the extent of equatorial and sub tropical deforestation, the soot deposits on the polar ice caps, the increase in atmospheric water vapour due to a corresponding increase in ocean temps and changes in ocean currents, the extreme ice albedo currently happening in the arctic etc, etc are all conspiring in tandem to alter the climate as we know it.

Sea level rise is caused by the melting of polar ice caps and the expansion of water when it is warmed, both triggered by global warming.

This would trigger a greenhouse effect, warming the atmosphere further and causing the water ice in the polar caps to melt.

As the last major ice age began to recede around 17,000 years ago, polar ice caps in the north and south started to melt, releasing vast quantities of fresh water into the salty oceans, altering natural currents, affecting the environment.

AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing water mass from equatorial latitudes and transporting this water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..

This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

When the convective processes of the atmosphere remove enough water vapor from the oceans to drop sea levels and build polar ice caps, as has happened many times before, the top 35 meters of the oceans where climate models assume the only thermal mixing occurs, must heat up cold ocean water that comes from depths below the original 35 meter depth, removing vast more amounts of heat from the earth's surface and atmosphere.
