More Bubbles Means More Variation in Ocean Carbon Storage
A new model accounting for the role of bubbles in air-sea gas exchanges suggests that ocean carbon uptake is more variable than previously thought.

Dry Heat, Wet Heat, and Wetland Methane Emissions
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.
