Compound weather events—such as extreme cold or heat combined with severe dryness or precipitation—have a greater effect on wetland methane emissions than discrete weather extremes do.

Thawing Permafrost Is Affecting Climate, but It’s Unclear by How Much
Models produce widely varying estimates of how ecosystems in the northern permafrost region are currently affecting the global greenhouse gas budget.

Each Glacier Has a Unique Organic Matter Composition
Like snowflakes, no two glaciers are alike: Carbon-containing compounds released from glaciers vary from place to place, meaning climate and ecosystem effects of melting could vary as well.

Northern Permafrost Region Emits More Greenhouse Gases Than It Captures
Permafrost underlies a quarter of the Northern Hemisphere. A comprehensive analysis shows that the area may have shifted from a sink to a source of greenhouse gases, bringing a longtime prediction to fruition.

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.

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.
