When it's cold enough to form ice shelves that extend over the Antarctic land mass and into the ocean, much of what drops to the seafloor is sand and gravel that the glacier has picked up on its slow march from the continent's ice cap.

During ice ages, which are mainly driven by rhythmic variations in Earth's orbit and spin that alter sunlight in the Northern Hemisphere, growing ice caps and glaciers trap so much frozen water on land that sea levels can drop a hundred meters or more.

«Based on the UN climate panel's report on sea level rise, supplemented with an expert elicitation about the melting of the ice sheets, for example, how fast the ice on Greenland and Antarctica will melt while considering the regional changes in the gravitational field and land uplift, we have calculated how much the sea will rise in Northern Europe,» explains Aslak Grinsted.

Because so much water was stored on land as ice sheets, sea levels were likely 120 meters lower than today, exposing the bottom of what is now the English Channel.

The land bridge forms during ice ages, when much of the water on the planet becomes part of growing continental glaciers, making the sea level much lower than it is today,» explained Shapiro.

Again, Monckton must surely know full well that for the last 25 - 30 years satellite temperature measurement of sea and land surface have replaced terrestrial temperature station measurements in many cases since these give a much greater coverage (70 % of the surface of the Earth is water... it's difficult to put weather stations on top of ice sheets etc.!)

This warm period, much like the roman and medieval warm periods, will bump against the upper bound, opening the Arctic and creating massive snows that will bump it down again until the ice volume on land becomes massive enough to advance and cool us again.

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..

The natural variation that has led us out of the Little Ice Age has a bit of frosting on the cake by land use; and, part of that land use has resulted in a change in vegetation and soil CO2 loss so that we see a rise in CO2 and the CO2 continues to rise without a temperature accompaniment (piano player went to take a leak), as the land use has all but gobbled up most of the arable land North of 30N and we are starting to see low till farming and some soil conservation just beginning when the soil will again take up the CO2, and the GMO's will increase yields, then CO2 will start coming down on its own and we can go to bed listening to Ave Maria to address another global crisis to get the populous all scared begging governments to tell us much ado about... nothing.

There are plenty of much clearer ones, from increasing surface temperature (the global warming itself), to melting of ice on land and sea, to the long - term cooling of the stratosphere, increasing intensity of heavy rain events, etc..

She stated, «With the pack ice retreating further and further north every year, they tend to be stuck on land where there's not much food,» and «many times I have seen horribly thin bears, and those were exclusively females — like this one here» and «Only once I have seen a bear getting a big fat «5,» but several times I have seen dead bears and bears like this one: a mere «1» on the scale, doomed to death.»

Losing land ice means sea levels will rise, and if we lose a lot of ice in Greenland and Antarctica — which we are very much on track for doing — sea levels could rise several meters.
