Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The recent deglaciation of Greenland is a response to both oceanic and atmospheric forcings. From 2000 to 2010, ice loss was concentrated in the southeast and northwest margins of the ice sheet, in large part due to the increasing discharge ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

High export of dissolved silica from the Greenland Ice Sheet
Geophysical Research Letters, 2016 Silica is an essential element for marine life and plays a key role in the biogeochemistry of the ocean. Glacial activity stimulates rock weathering, generating dissolved silica that is exported to coastal areas along with meltwater. The magnitude of the

Contribution of the Greenland Ice Sheet to sea level over the next millennium
Science Advances, 2018 Simulations show that the Greenland Ice Sheet could disappear within a millennium if greenhouse gas emissions continue unabated. The Greenland Ice Sheet holds 7.2 m of sea level equivalent and in recent decades, rising temperatures have led to ...

Past Warmth and Its Impacts During the Holocene Thermal Maximum in Greenland
Annual Review of Earth and Planetary Science, 2020 Higher boreal summer insolation in the early to middle Holocene drove thousands of years of summer warming across the Arctic. Modern-day warming has distinctly different causes, but geologic data from this past warm period hold lessons for the future. We
