Exchanges between ice sheets or glaciers and the oceans;
When there is more sunlight at high latitudes in summer, ice sheets melt.
Glaciers and ice sheets move downhill due to gravity.
According to scientists, the rise in sea level is accelerating, mainly due to the Greenland and Antarctic ice sheets melting faster.
This includes sea ice, ice sheets, permafrost and snow cover.
Eleven other major centers oversee research in life span issues, the humanities, transportation, the environment, biosciences, biodiversity,and polar ice sheets, among others.
Scientists believe the ice sheets in Greenland and West Antarctica will become unstable and melt.
Hansen joined other climate scientists in warning of increasingly violent storms, plant and animal extinctions,melting ice sheets and rising sea levels-- if mankind fails to act.
During the recent Pleistocene glaciation,heavy continental ice sheets scoured and depressed the region, leaving as they melted a flat landscape of lakes and rivers.
Earlier this year he published a study in Nature Climate Change that looked at similar upwelling patterns causing drastic melting in the West Antarctic, where most ice sheets and glaciers have their base below sea level.
WASHINGTON- New satellite research shows melting ice sheets in Greenland and Antarctica are speeding up already rising seas.
According to NASA, the studies of this mission showed gravitational differences“due to surface and deep currents in the ocean; runoff and ground water storage on land masses;exchanges between ice sheets or glaciers and the oceans; and variations of mass within the Earth.”.
For example, measuring the height of the oceans and ice sheets and positioning of tectonic plates requires knowing the position of the satellite with centimeter-level accuracy.
Even so, Dr. James Hansen,“the father of modern climate change awareness,” warned at the time,“The primary issue is whether global warming will reach a level such that ice sheets begin to disintegrate in a rapid, non-linear fashion on West Antarctica, Greenland or both.”.
When these great ice sheets retreated they left pulverised rocks in their wake the foundation for fertile soil and some of the richest natural grasslands in America.
They are made of freshwater since they are fragments of glaciers or ice sheets, formed on land, that move slowly into the sea over thousands of years.
It would have led to expanded ice sheets in Siberia that could have closed the Native American ancestors off on the east side of an icy wall, and indications are that human presence in Siberia dropped during this time.
Those are seals from many countries being released who are sampling underneath the ice sheets and giving us temperature data of oceanographic quality on both poles.
The Great Lakes began to form at the end of the last glacial periodaround 14,000 years ago, as retreating ice sheets exposed the basins they had carved into the land which then filled with meltwater.
On local scales, temperature differences can occur because different surfaces(such as oceans,forests, or ice sheets) have differing physical characteristics such as reflectivity, roughness, or moisture content.

Compiled by more than 100 authors who crunched 7,000 academic papers, the study documents the implications of warm,fast-melting ice sheets in Greenland and Antarctica and shrinking glaciers for more than 1.3 billion people living in low-lying or high-mountain regions.
Greenland Ice Sheet:'More than 50 hidden lakes' detected.
The study projected a sea level rise of 1.3 m(4.3 ft) from the West Antarctic Ice Sheet if all the sea ice in the Amundsen Sea melted.
The ice is estimated to be about 2,700 meters(9,000 ft) thick at the Pole,so the land surface under the ice sheet is actually near sea level.
Scientist have suggested that the loss of these glaciers would destabilise the entire West Antarctic ice sheet and possibly sections of the East Antarctic Ice Sheet. .
This is undoubtedly the most accurate portrait yet of what lies beneath Antarctica's ice sheet.
If the ice sheet melts entirely, the sea levels will be more than 7 m higher and Greenland may become an archipelago.
If the Greenland ice sheet were to completely melt away, sea level would rise by more than 7 m(23 ft) and Greenland would most likely become an archipelago.
A whopping total of 138 volcanoes are believed to cover the vast West Antarctic Ice Sheet, which straddles the West Antarctic Rift System.
