from What On Earth
Clues to Earth’s climate future lie buried in the ancient ice sheet covering Greenland. Climate scientists have been working for decades to uncover answers that can help us understand what’s coming. But as the U.S. government continues to push for more control over the island, some are worried that a Greenland controlled by Donald Trump would put their access to the ice in jeopardy. Security expert Whitney Lackenbauer tells us why fears about a warming Arctic due to climate change are stoking the current geopolitical tensions, and glaciologist Martin Siegert explains why a politically stable Greenland matters for the whole planet.
