Managing Carbon Stocks Requires an Integrated View of the Carbon Cycle

by Donald Wuebbles 9 January 20262 February 2026

The carbon cycle community calls for an integrated carbon observing system leveraging near-surface partial-column data to better resolve finer spatial scales where key processes and decisions occur.

New River Chemistry Insights May Boost Coastal Ocean Modeling

Sarah Stanley, Science Writer by Sarah Stanley 9 January 20269 January 2026

By more realistically accounting for river inputs, researchers reduced overestimation of the amount of carbon dioxide absorbed by coastal waters.

What Could Happen to the Ocean’s Carbon If AMOC Collapses

by Rebecca Owen 6 January 20266 January 2026

Mass glacier melting may have led this influential ocean current system to collapse at the end of the last ice age. A pair of modeling studies examines how such a collapse could affect dissolved inorganic carbon and carbon isotopes in Earth’s oceans.

A backward C-shaped swirl of milky blues and greens appears against a deep blue background. In the foreground, toward the edges of the image, clouds appear as white patches.

A Better Way to Monitor Greenhouse Gases

by Dustin Carroll, Nick Parazoo, Hannah Nesser, Yinon Bar-On and Zoe Pierrat 24 October 20252 February 2026

A unified, global observing system could more effectively monitor progress in reducing emissions and accelerate climate action through improved data and decision support.

The Southern Ocean May Be Building Up a Massive Burp

Sarah Derouin, Science Writer by Sarah Derouin 20 October 202520 October 2025

Modeled results suggest that if anthropogenic emissions decrease and the atmosphere cools, heat stored in the Southern Ocean could be released abruptly in a few hundred years, kicking off a temporary warming period.

Old Forests in the Tropics Are Getting Younger and Losing Carbon

by Kaja Šeruga 2 October 20252 October 2025

New research quantifying the global impact of forest age transitions found that 140 million tons of aboveground carbon are lost per year because of old-growth forests being replaced by younger stands.

Rising CO2 and Climate Change Reorganize Global Terrestrial Carbon Cycling

by Sharon Billings 17 September 202517 September 2025

Rising CO2 and climate change are redistributing terrestrial carbon fluxes and reservoirs across latitudes and reducing carbon residence times globally.
