Greenland's vast ice sheet, covering 80% of the island and two miles thick, serves as the world's largest natural laboratory. By studying minerals and gases trapped in ice cores, glaciologists unravel ancient mysteries—like past temperatures or the disappearance of the Norse—and gain critical insights into the future of climate change.

Subscribe to Big Think Edge for insights into critical global issues. The Arctic is warming twice as fast as the rest of the world, causing Greenland's ice to melt. This exposes dark ocean, which absorbs more solar energy, creating a feedback loop that accelerates further ice melt.

Journalist and historian Jon Gertner, a feature writer for the New York Times Magazine, explores this phenomenon in his latest book, "The Ice at the End of the World: An Epic Journey into Greenland's Buried Past and Our Perilous Future." Find his book here.

Sea level rise has already claimed islands like Holland Island in the Chesapeake Bay. Experts predict at least two feet of rise by 2100, even in best-case scenarios. This raises critical questions

Sea level rise has already claimed islands like Holland Island in the Chesapeake Bay. Experts predict at least two feet of rise by 2100, even in best-case scenarios. This raises critical questions about future displacement as flooding worsens and communities lose hope.

Journalist and historian Jon Gertner, a New York Times Magazine feature writer and author of The Ice at the End of the World, explores these pressing environmental and societal challenges.
