Julie Brigham-Grette, 2017 PEP Fellow, featured in the NOVA program “Polar Extremes” discussing climate change

Julie Brigham-Grette, 2017 PEP Fellow, is featured in the NOVA program “Polar Extremes.” She explains how ice cores from a frozen lake in northern Russia show how the climate has changed over time and how even what is now part of the frozen arctic at one time was much more moderate in temperature and had different plant and animal life. The ice cores were taken from a lake that was created by a meteor strike 3.5 million years ago. The segment begins at 1:04:00.
