  • Like a prehistoric fly trapped in amber during dinosaurs' days, airborne relics of Earth's earlier climate can end up trapped in glacial ice for eons. How do climate scientists turn those tiny relics into a story about Earth's ancient climate?

  • Although most drifting buoys start their journeys with a crude send-off—usually heaved into the ocean from the stern of a moving ship—NOAA oceanographer Rick Lumpkin describes today's drifter as "a high-tech message in a bottle."  Insignificant on their own, but an army of drifters 1,000 strong patrols the world's oceans and records key data for climate monitoring and research.
