Climate change - we all know that it's happening, but how do we actually know this scientifically? Bruce Vaughn studies glaciers up at the North Pole, looking at ice cores to study how our climate has changed over the Earth's history. We talk about how this is done, and also how we are now entering uncharted territory of atmospheric CO2, warming, and what we as a species can do about it.
Bruce Vaughn runs the stable isotope lab at the Institute of Arctic and Alpine Research (INSTAAR) at the University of Colorado.
