Can Submerging Seaweed Cool the Climate?

by Saima May Sidik 16 January 202420 March 2024

Submerged seaweed can store carbon at the bottom of the ocean, but how effective the strategy will be—and how it will affect ocean health—remains unclear.

A Transformative Carbon Sink in the Ocean?

by Doug Reusch, Kayleigh Brisard, Gil Hamilton and Carson Theriault 12 December 202312 December 2023

Water-rock reactions in some hydrothermal systems produce both hydrogen, which could be tapped for clean energy, and alkaline solutions that could help draw down atmospheric carbon dioxide.

Ocean Deserts Could Help Capture CO2 and Mitigate Global Warming

by Minhan Dai, Ya-Wei Luo, Hongyang Lin, Eric P. Achterberg, Thomas J. Browning, Matthew J. Church, Zhongping Lee and Wei-Lei Wang 1 December 20234 December 2023

Various nutrient sources in the upper waters of oceanic subtropical gyres, which are the Earth’s largest oligotrophic ecosystems, play a crucial role in governing the sequestration of atmospheric CO2.

Grow-Fast-Die-Young Strategy Increases Swiss Forest Biomass

Eric Davidson, president-elect of AGU by Eric Davidson 2 November 202331 October 2023

Climate change and CO2 fertilization can increase both growth and mortality of trees. The net effect on forest biomass depends on that trade-off, which long-term studies in Switzerland reveal.
