Restored Tropical Forests Recover Faster Than Those Left Alone

by Mohammed El-Said 3 September 202019 October 2022

The costs of active restoration may be offset by aggressive carbon pricing demanded by the Paris Agreement.

Ideal Temperatures for Carbon Uptake by Subtropical Plants

by Elizabeth Thompson 26 August 202010 February 2022

Air temperatures in coastal ecosystems of Australia routinely exceed the optimum range for photosynthesis, hindering plants’ ability to take up atmospheric carbon.

Soil Carbon May Not Remain Bogged Down in a Warmer World

by E. Davidson 27 July 20201 April 2022

Carbon was lost from an experimentally warmed boreal peatland much faster than it took to accumulate. Elevated CO2 had little effect on stored carbon, requiring re-evaluation of model assumptions.

The Arctic Ocean May Not Be a Reliable Carbon Sink

by Hannah Thomasy 7 April 202025 January 2023

The rapid changes happening in the Arctic Ocean, including increasing freshwater input, could dramatically affect its ability to store carbon.

Florida Coastlines Respond to Sea Level Rise

by Elizabeth Thompson 1 April 202010 February 2022

For more than a century, carbon burial rates have been increasing on some southern Florida coasts. Scientists now verify this trend and propose an explanation.

Tropical Forests Are Losing Their Ability to Soak Up Carbon

by Jenessa Duncombe 9 March 202029 April 2022

The forests could switch from a carbon sink to a carbon source by the mid-2030s.

The Future of the Carbon Cycle in a Changing Climate

by A. Kaushik, J. Graham, K. Dorheim, R. Kramer, J. Wang and B. Byrne 20 February 20201 April 2022

Surface and space-based observations, field experiments, and models all contribute to our evolving understanding of the ways that Earth’s many systems absorb and release carbon.

Wooden Buildings Could House the Carbon of the 21st Century

by J. Wosen 27 January 202031 January 2022

To keep carbon out of the atmosphere, researchers argue that we need to return to one of the world’s oldest building materials: wood.

Ship-Based Measurements Overestimate Southern Ocean Carbon Sink

by Kate Wheeling 19 November 201917 August 2022

New research suggests that combining ship- and float-based observations provides a more accurate measure of how much carbon the Southern Ocean absorbs.

Peatlands Are Drying Out Across Europe

by Michael Allen 14 November 20191 April 2022

Peatlands are some of the world’s largest reservoirs of soil carbon, but new research finds that in Europe they are drying out, putting them at risk of turning from carbon sinks to carbon sources.
