Real Climate Solutions Are Beneath Us

by Peter Reiners 2 May 20252 May 2025

It’s time to accept that durable subsurface carbon storage, along with emissions reductions, must be part of the plan to mitigate the effects of climate change—and geoscience must play a central role.

Compost and Biochar Could Boost Carbon Sequestration by Crushed Rock

by Nathaniel Scharping 22 April 202522 April 2025

Crushed rock additives may also help decrease soil emissions of other greenhouse gases, such as nitrous oxide and methane.

Louisiana’s Wetlands Store Massive Amounts of Carbon. But When Destroyed, They Release It.

by Elise Plunk 14 March 202514 March 2025

Louisiana’s wetlands are one of the planet’s most vital carbon storage centers, but destroying these reservoirs can accelerate harmful emissions that intensify global warming, according to experts.

Erosion: An Overlooked Contributor to the Carbon Cycle

by Haiyan Zheng and Chiyuan Miao 13 March 202512 March 2025

Since physical and chemical erosion yield comparable carbon fluxes, studying both together is essential to avoid biases in erosion-driven carbon flux estimates.

Turning Carbon into Stone: Unlocking Mineralization in Fractured Rock

by Haylea Nisbet and Hari Viswanathan 29 January 202529 January 2025

Carbon mineralization is a promising solution for mitigating greenhouse gas emissions, but we must learn to optimize the complex interplay between reactions and mechanics in fractures to develop a scalable solution.

As Seas Rise, Marshes May Still Trap Carbon—and Cool the Planet

by Rambo Talabong 10 December 202410 December 2024

Rising seas spell doom for coastal wetlands trapping carbon—or do they? New research reveals that as these ecosystems transition, they can still trap carbon and possibly cool the planet.

Rainfall Makes the Ocean a Greater Carbon Sink

by Veronika Meduna 22 October 202414 November 2024

Rain has so far been ignored in calculations of the ocean’s capacity to take up carbon, but a new estimate shows it enhances the ocean sink by 5%–7%.
