The trade-off between tree longevity and life expectancy can mean future carbon uptakes are overestimated in current global climate models.

Researchers Unearth Bedrock Carbon and Water Dynamics
Deep tree roots bring respiring microbes into broken bedrock, generating carbon that’s released into the environment. New research explores this oft-overlooked carbon source.
Determining Dissolved Organic Carbon Flows into the Gulf of Alaska
A new model determines freshwater and dissolved organic carbon discharge to the Gulf of Alaska from one of the most geographically diverse but understudied regions on the planet.
Experimentos Revelan Cómo el Carbono del Permafrost se Convierte en Dióxido de Carbono
Muestras de campo provenientes de Alaska muestran cómo la luz solar y el hierro convierten el carbono del permafrost en dióxido de carbono. Los modelos climáticos ignoran este proceso.
El Zooplancton Gelatinoso Transfiere Una Cantidad Significativa de Carbono a las Profundidades del Océano
Un nuevo estudio muestra que las medusas y las salpas marinas no reciben el crédito que merecen por su papel en el ciclo del carbono en el océano.
Dirty Trees Shape Earth’s Hydrologic and Carbon Cycles
Researchers peer into precipitation partitioning—the process by which plants and the organic matter coating them help shape the hydrologic cycle.
Feedback Loops of Fire Activity and Climate Change in Canada
New research documents how a warming climate contributes to patterns in wildfire severity and frequency and how the fires contribute to climate change.
High Climatic Response of High-Latitude Forests
The seasonal amplitude of atmospheric CO2 is increasing, partly due to boreal forest responses to warming. Photosynthesis and expansion of boreal forests are shown here to be temperature-limited.
A Promising Development for Detecting Ocean Productivity
A comparison of primary productivity measurements across the North Pacific Ocean demonstrates the potential for using autonomous instruments to discern effects of climate change on the marine food web.
How Long Does Iron Linger in the Ocean’s Upper Layers?
A new study refines our understanding of marine residence times of iron, which supports carbon-sequestering sea life, offering valuable data to inform biogeochemical models.
