Science editor Tom Clarke shares insights from his recent expedition to Antarctica, where he documented alarming ice melt and observed mild summer conditions. He emphasizes the continent's critical role in global sea level rise and contrasts its vast, thick land ice with the Arctic's sea ice. Clarke discusses the geopolitical landscape as the U.S. withdraws, allowing Russia and China to expand their influence. He warns that glaciers like the Thwaites could trigger catastrophic sea level changes, highlighting the need for urgent scientific attention to this frozen frontier.
