Scientists Look to Soil for Answers on Climate Change

Plant life on our planet is reacting to the changing climate. So scientists like Jane Zelikova are turning to the soil for an insight as to what is going on. Here in Kansas we see her and her research colleague Dr. Megan Machmuller digging down to take soil and root samples. She explains how grass systems play a vital role in carbon sequestration and the importance of necromass.
