Ice core secrets could reveal answers to global warming
It's a freezing cold day inside the National Ice Core Laboratory (NICL) in Denver, Colo., as it is every day of the year. That's because the NICL is a facility for storing and studying ice cores recovered from the polar regions of the world. It's minus 23.3 degrees Celsius (minus 10 degrees Fahrenheit) inside, so everyone is bundled up in ski parkas, insulated gloves and boots. And, saws are buzzing, as scientists from all over the U.S. are measuring and cutting pieces of precious Antarctic glacier ice to take back to their labs for research.
This is an episode from Science Nation, NSF's online magazine that's all about science for the people.
