Root-filled soils are hot spots of nutrient cycling and carbon storage. New research finds that the world has lost millions of cubic meters of rooted soil volume—and we’re on track to lose much more.

The Bottom of the Arctic Is Blooming
Researchers found phytoplankton hidden on the Arctic seafloor, hinting at a cascade of effects on the local ecology and carbon cycle.
Testing the Resilience of the Amazon
A mega-experiment in Brazil will evaluate how tropical rain forests absorb carbon as emissions increase.
Respiration Quotient Variability and Ocean Oxygen Levels
Respiration quotients in the Atlantic and Pacific Oceans reflect different water temperature, nutrient stress and phytoplankton community structure, important for regional carbon and oxygen cycling.
Tracing Anthropogenically Emitted Carbon Dioxide into the Ocean
Researchers labeled anthropogenically emitted carbon and tracked it with an ocean circulation model to determine whether it winds up in the sky or sea.
The Burning Tundra
As wildfires blaze through the Arctic, scientists examine the role of landscape characteristics on wildfire ecosystem responses in northern aquatic ecosystems.
Can These Rocks Help Rein in Climate Change?
Spreading olivine on beaches could accelerate ocean uptake of carbon dioxide and potentially limit climate change. The concept and execution still face some scrutiny from scientists.
Substantial Advance Towards a Global Coastal Carbon Model
First simulations of a new biogeochemistry-circulation coastal grid refinement demonstrate seamless inclusion of small-scale coastal processes in a state-of-the-art Earth system model.
Exploring Carbon Emissions in Peatland Restoration
Rewetting bogs can increase methane emissions in the short term, but ultimately the approach helps restore peatlands and create larger carbon sinks.
A New Look at Preindustrial Carbon Release from the Deep Ocean
New research could help inform future studies of how the release of carbon dioxide from the Southern Ocean might affect global climate change.
