Climate Change Solutions: Managing the Global Carbon Cycle
Soil has a large capacity for carbon storage, yet the global soil carbon pool has been degraded over many centuries. How can the degradation of soil from agricultural land management practices or the thawing of permafrost in the Arctic contribute to increasing greenhouse gas concentrations in the atmosphere?
At this Midday Science Café, you’ll learn about two projects that aim to increase understanding of the global carbon cycle. Allegra Mayer will discuss how managing agricultural land could provide a low-tech, negative emissions solution to draw down atmospheric carbon and increase soil carbon storage, and Nancy Freitas will discuss how quantifying carbon dioxide and methane emissions released from deep lake sediments in the Arctic can improve Earth system models, advancing the quality of climate model projections.
