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.

Framing the Next Decadal Survey for a Warming World
The next decadal survey (DS28) will be framed by a rapidly changing world, and will be critical to consider observational needs of the 2030s-2040s, a world increasingly dominated by climate extremes.

Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle
While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.
