Icebergs break off and flow through Greenland’s coastal waters. The stunning ice armada comes at a potentially high cost to the island’s disappearing ice sheet.
Climate researchers are racing to collect clues exposed as Greenland's vast ice sheet melts. The goal is to better understand how unprecedented warming could affect the not-so-frozen north and the rest of the world.
Scientists find that climate conditions in the Southern and Northern hemispheres used to be very different. Their research underscores the unprecedented nature of current climate change, with rapid warming causing the unusual match.
China, with one of the world's fastest growing economies and skyrocketing energy use, still left a gaping hole in the global climate change map - until recently. What an international team of scientists found there surprised them.
