Surface meltwater that drains to the bed of the Greenland Ice Sheet each summer causes changes in ice flow that cannot be fully explained by prevailing theories. Surface meltwater that drains to the ...

The dynamic response of the Greenland Ice Sheet (GrIS) depends on feedbacks between surface meltwater delivery to the subglacial environment and ice flow. Recent work has highlighted an important role ...

The study, called Subglacial lake drainage detected beneath the Greenland Ice Sheet is published in the journal Nature Communications. Lead author Dr Steven Palmer, from Geography at the University of ...

During the late stages of the Little Ice Age, the glaciers of the Canadian Pacific Northwest had a profound influence on the Tlingit and Athapaskan native communities, changing their trading routes ...

Advances in satellite technology over recent decades have allowed scientists to chart the melting of the Earth’s ice sheets in remarkable detail. Meltwater on the surface that finds its way to the ...

Deep valleys buried under the seafloor of the North Sea record how the ancient ice sheets that used to cover the UK and Europe expelled water to stop themselves from collapsing. A new study published ...
