What is carbon sequestration? And how can it fight climate change and help farmers grow more food? In the video above, shot at May’s Save Our Soils seminar in Sweden and posted by The Organic Stream, CFAES’s Rattan Lal, a world expert on such matters, explains. Why it matters: At this week’s U.N. Climate Change Conference in Paris, world leaders for the first time have “made the capture of carbon in soil a formal part of the global response to the climate crisis,” said an NPR blog post. Lal heads CFAES’s Carbon Management and Sequestration Center, which is mentioned in the post.
