Antarctic ice sheet melting and climate
Science, 2020Climate Change The massive West Antarctic Ice Sheet (WAIS) is now melting at an accelerated rate in response to anthropogenic greenhouse gas emissions, and exactly how this will affect global climate remains poorly understood. Widely available predictive global climate models do not adequately account for ice sheet physics.

1989
Although there are needs for a better understanding of the atmosphere-snow and ice connection and for improving deep ice dating polar ice cores are providing multiple proxy records of climate and related parameters. They show evidences of anthropogenic impact on aerosol concentrations in Greenland snow (i.e.

Interglacial Climates and Antarctic Ice Surges
Quaternary Research, 1972Wilson's theory of ice ages implies that the present interglacial will end with, or at least be interrupted by, an Antarctic ice sheet “surge”. Such surges in the past would have caused distinctive rises of sea level: by 10–30 m, in 100 yr or much less, and precisely at the break of climate at the end of each interglacial.

Arctic Oceanography, Sea Ice and Climate
2019The Arctic Ocean, almost completely enclosed by the surrounding land masses of Eurasia, North America and Greenland, is the smallest of the world’s oceans and unique in the maintenance of a year round ice cover. In the Arctic Ocean, the warmer Atlantic water entering the Greenland, Iceland and Norwegian Seas sinks beneath the colder water from the ...

Climate change and ice breeding pinnipeds
2001Pinniped diversity is greatest in seasonally ice-covered seas where the risk of predation is minimised. In recent decades, the thickness and extent of seasonal ice cover has decreased in the Arctic, and climate models predict that positive feedback from melting ice covers will result in rapid warming in the polar regions.

Snow and Ice Cover and Climate Sensitivity
1995The area of the earth covered by snow, sea ice and land ice is about 16%. According to calculations with a zonal season-resolving climate model, the earth climate would be 2.6 °C warmer without snow and ice cover. Local changes in the seasonal cycle would be much larger, however.

Modelling Ice Sheet and Climate Changes through the Ice Ages
1993A three dimensional ice sheet model and a global energy balance climate model have been used to investigate the evolution of ice and climate changes through the ice ages. Sensitivity studies give an indication of the conditions required for the growth and decay of the ice sheets. Time series simulations in response to orbital forcing show the dominance
