Being Cool is a Slow Ride When You’re a Restored Wetland

by Ankur R. Desai 16 February 202215 March 2022

Restoring formerly drained peat wetlands can mitigate climate-warming emissions but the reward takes patience.

A wide and flat rock sample with a gray exterior sits on a lighter gray background. Green crystals inside the rock are exposed on the side of the rock facing forward. The crystals are small and uniform in size and light green to dark green in shade.

Good News: Rocks Crack Under Pressure from Mineral CO2 Storage

by Kimberly M. S. Cartier 3 February 202222 September 2022

When carbon mineralizes in stone, each new fracture exposes more surfaces that can react with and trap CO2, enhancing a rock’s storage capacity.

Permanence of Nature-Based Climate Solutions at Risk

by E. Davidson 22 July 20213 May 2022

Conserving native ecosystems helps sequester carbon and mitigate climate change, but new statistical modeling questions the permanence of California’s carbon-rich forests with climate change.

Acidifying Oceans Could Get Help from Kelp

by Elizabeth Thompson 30 November 202010 February 2022

Forests of fast-growing kelp influence the chemistry of the water in which they live. A new study evaluates their potential to ameliorate ocean acidification in sensitive coastal ecosystems.
