Racing against time to rescue 150,000 years of climate history

Science Bulletins: Archived in Ice—Rescuing the Climate Record · 7:33 · Video: American Museum of Natural History · Watch at the source

In short: Scientists are venturing into high-altitude peaks to extract ancient ice before it vanishes forever. This video follows a team's mission to preserve a literal archive of our planet's atmospheric past.

Lonnie Thompson and his researchers from Ohio State University are working on the Quelccaya ice cap in the Peruvian Andes. Their goal is to extract 1,500-year-old ice cylinders that hold critical data on historical climate patterns.

By studying these global ice cores, glaciologists can access a remarkably preserved environmental record spanning 150,000 years. This data is essential for developing more accurate models to predict how our warming world will behave in the future.
