East Greenland ice core dust record reveals timing of Greenland ice sheet advance and retreat
Accurate estimates of the past extent of the Greenland ice sheet provide critical constraints for ice sheet models used to determine Greenland’s response to climate forcing and contribution to global sea level. Here we use a continuous ice core dust record from the Renland ice cap on the east coast...

Accurate estimates of the past extent of the Greenland ice sheet provide critical constraints for ice sheet models used to determine Greenland’s response to climate forcing and contribution to global sea level.

These findings constrain the possible response of the Greenland ice sheet to climate forcings. |
