Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, even as the WAIS warmed by over 0.1 °C ...
A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it.

Over the course of the 19-year survey (1992 – 2011), the average rates of mass balance of the Antarctic and Greenland ice sheets were estimated to be -71 ± 53 and -152 ± 49 Gt yr −1, respectively, and the total ice loss equated to a global rise in sea level of 11.1 ± 3.8 mm. [2] Examining the ice sheet regions individually showed that ...
Antarctica is actually gaining ice mass thanks to snow and instead of driving sea level rise, it may actually be slowing it down.
The Antarctic ice sheet is melting in a new, worrying way that scientific models used to project future sea level rise have not taken into account, suggesting current projections could be ...
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
Sea ice is a complex composite composed primarily of pure ice in various states of crystallization, but including air bubbles and pockets of brine.Understanding its growth processes is important for climate modellers and remote sensing specialists, since the composition and microstructural properties of the ice affect how it reflects or absorbs sunlight.
The gigantic wall of ice is moving slowly from Antarctica on a potential collision ... As A23a ultimately melted it could seed the water with nutrients that encourage phytoplankton growth, feeding ...
