Animals Deserve to Be Included in Global Carbon Cycle Models, Too
Because they are far less plentiful than plants and microbes, animals have typically been excluded from examinations of carbon exchange in the atmosphere. But new research shows they may have a considerable influence on carbon cycle dynamics.

Africa’s Carbon Sink Capacity Is Shrinking
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.
