Greenland's Icy History Plays Huge Role in Climate Change Survival, Country Once Ice-Free for 280,000 Years

The mystery behind Greenland’s icy history, where it was ice-free for 280,000 years, could help in research for climate change survival. However, mapping the history of the ice growth and shrinkage proves to be a remarkably difficult task. While researchers are digging deeper into the past, the ice narrative is becoming even more tangled.
