NASA | Greenland's Ice Layers Mapped in 3D

The video discusses a study on the Greenland ice sheet, revealing its climate history through ice core analysis and radar mapping. It highlights three distinct climate periods: the Holocene, the last Ice Age, and the Eemian. The study uses NASA's Operation Icebridge data to create a 3D age map, showing more Eemian ice than expected in northern Greenland. This research helps understand the ice sheet's response to past and current climate changes.

What do scientists use to recover a record of the ice's age and past climate?

Describe the significance of the 3D age map generated from the Greenland ice sheet.

What are the three distinct periods of climate evident within the ice sheet?

How do layers from the last Ice Age differ from those formed during the Holocene?

What does the new analysis reveal about the Eemian ice in northern Greenland?
