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.
Inland Waters Are a Blind Spot in Greenhouse Gas Emissions
Researchers call for an extensive monitoring network to quantify carbon dioxide and methane released by China’s rivers, lakes, reservoirs, and ponds.
Source or Sink? A Review of Permafrost’s Role in the Carbon Cycle
Understanding the role of permanently frozen soil, which covers a large portion of land in the Northern Hemisphere, is crucial to reaching global climate targets.
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.
Measuring and Modeling Methane Emissions in Wetlands
Scientists zero in on a Delaware salt marsh to study what shapes methane emissions in wetland environments.
Bottom Trawling Shreds the Seafloor. It May Also Be a Huge Source of Carbon Emissions.
Dragging nets along the ocean bed wrecks marine life, but researchers can’t agree on how bad it is for the climate.
Researchers Develop Mexico’s First Comprehensive Greenhouse Gas Budget
A new study delves into 2 decades of data to create a comprehensive quantification of carbon, methane, and nitrous oxide sources and sinks that could help guide climate policy.
Current Efforts Not Enough to Keep Warming Under 1.5°C
A canyon between current efforts and necessary action means global temperatures are on track to rise far beyond Paris Agreement goals.
