Soil Carbon Sequestration for Climate Change Mitigation: What We Can Expect

William Schlesinger

Thursday, 04 Oct 2018 at 4:10 pm – 2050 Agronomy Hall

Dr. William Schlesinger, member of the NAS and former director of the Cary Institute and former Dean of Duke University’s Nicholas School of the Environment. Improved soil management is increasingly pursued to ensure food security for the world’s rising global population, with the ancillary benefit of storing carbon in soils to lower the threat of climate change. While all increments to soil organic matter are laudable, we suggest caution in ascribing large, potential climate change mitigation to enhanced soil management. We find that the most promising techniques, including applications of biochar and enhanced silicate weathering, are not likely to balance more than 5% of annual emissions of CO2 from fossil fuel combustion. 2018 William H. Pierre Memorial Lecture in Soil Science

Stay for the entire event, including the brief question-and-answer session that follows the formal presentation. Most events run 75 minutes.

Sign-ins are after the event concludes. For lectures in the Memorial Union, go to the information desk in the Main Lounge. In other academic buildings, look for signage outside the auditorium.

Lecture Etiquette

  • Stay for the entire lecture and the brief audience Q&A. If a student needs to leave early, he or she should sit near the back and exit discreetly.
  • Do not bring food or uncovered drinks into the lecture.
  • Check with Lectures staff before taking photographs or recording any portion of the event. There are often restrictions. Cell phones, tablets and laptops may be used to take notes or for class assignments.
  • Keep questions or comments brief and concise to allow as many as possible.
