Massive East Antarctic Ice Sheet Has History Of Instability（图）
East Antarctic Ice Sheet History Instability
2017/12/19
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It's also thought to be among the most stable, n...
Study finds sudden shift in “forcing” led to demise of Laurentide ice sheet
forcing led to demise Laurentide ice sheet
2015/7/13
A new study has found that the massive Laurentide ice sheet that covered Canada during the last ice age initially began shrinking through calving of icebergs, and then abruptly shifted into a new regi...
Capabilities and performance of Elmer/Ice, a new-generation ice sheet model
Elmer/Ice ice sheet model

The Fourth IPCC Assessment Report concluded
that ice sheet flow models, in their current state, were unable to provide accurate forecast for the increase of polar
ice sheet discharge and the a...
Antarctic ice sheet is result of CO2 decrease, not continental breakup
Antarctic ice sheet result of CO2 decrease not continental breakup
2014/8/14
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decre...
Antarctic ice-sheet response to atmospheric CO2 and insolation in the Middle Miocene
Antarctic ice-sheet Middle Miocene atmospheric CO2
2009/12/3
Foraminiferal oxygen isotopes from deep-sea sediment cores suggest that a rapid expansion of the Antarctic ice sheet took place in the Middle Miocene around 13.9 million years ago. The origin for thi...
A quasi-analytical ice-sheet model for climate studies
quasi-analytical ice-sheet model climate studies
2009/11/12
A simple quasi-analytical model is developed to study the response of ice-sheets to climate change. The model is axisymmetrical and rests on a bed with a constant slope. The mechanics are highly param...
Ice thinning, upstream advection, and non-climatic biases for the upper 89% of the EDML ice core from a nested model of the Antarctic ice sheet
upstream advection EDML ice core Antarctic ice sheet
2008/11/7
A nested ice flow model was developed for eastern Dronning Maud Land to assist with the dating and interpretation of the EDML deep ice core. The model consists of a high-resolution higher-order ice dy...
The Eurasian ice sheet reinforces the East Asian summer monsoon during the interglacial 500 000 years ago
Eurasian ice sheet East Asian summer monsoon interglacial
2008/10/30
Deep-sea and ice-core records show that interglacial periods were overall less "warm" before about 420 000 years ago than after, with relatively higher ice volume and lower greenhouse gases concentrat...
