Middle-of-the-Road Mountains Form the Best Carbon Sinks

by Martin J. Kernan 26 April 202416 July 2025

Silicate rock weathering has a sweet spot: erosion that isn’t too fast or too slow.

How Are Deep Soils Responding to Warming?

by Fabrizzio Protti Sánchez, Avni Malhotra, Michael W. I. Schmidt, Cornelia Rumpel and Margaret S. Torn 17 April 202417 April 2024

Scientists aim to integrate observations from deep-soil-warming experiments worldwide to better understand how ecosystems vital to food security and environmental health will react to climate change.

Animals Deserve to Be Included in Global Carbon Cycle Models, Too

by Nathaniel Scharping 16 April 202416 April 2024

Because they are far less plentiful than plants and microbes, animals have typically been excluded from examinations of carbon exchange in the atmosphere. But new research shows they may have a considerable influence on carbon cycle dynamics.

Africa’s Carbon Sink Capacity Is Shrinking

Rachel Fritts, Science Writer by Rachel Fritts 4 April 20244 April 2024

A new estimate of Africa’s greenhouse gas budget from 2010 to 2019 shows increasing emissions from cropland expansion, livestock, and fossil fuel use—meaning the continent may have transitioned from an overall carbon sink to a slight carbon source.

Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle

Sarah Derouin, Science Writer by Sarah Derouin 4 March 20244 March 2024

While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.

The Open Ocean, Aerosols, and Every Other Breath You Take

by Rachel Shelley, Morgane M. G. Perron, Douglas S. Hamilton and Akinori Ito 1 March 20241 March 2024

Phytoplankton and other marine plants produce half of Earth’s atmospheric oxygen and have big effects on food webs and climate. To do so, they rely on nutrients from the sky that are hard to quantify.
