Cracking Soils Could Accelerate Climate Change

by Elise Cutts 7 May 20247 May 2024

Climate change is expected to lead to more frequent and intense drought, which in turn causes soil to crack, releasing more carbon dioxide and further warming the planet.

Africa’s Carbon Sink Capacity Is Shrinking

Rachel Fritts, Science Writer by Rachel Fritts 4 April 20244 April 2024

A new estimate of Africa’s greenhouse gas budget from 2010 to 2019 shows increasing emissions from cropland expansion, livestock, and fossil fuel use—meaning the continent may have transitioned from an overall carbon sink to a slight carbon source.
