Thawing Permafrost Is Affecting Climate, but It’s Unclear by How Much

by Saima May Sidik 29 October 202429 October 2024

Models produce widely varying estimates of how ecosystems in the northern permafrost region are currently affecting the global greenhouse gas budget.

Northern Permafrost Region Emits More Greenhouse Gases Than It Captures

by Saima May Sidik 15 April 202415 April 2024

Permafrost underlies a quarter of the Northern Hemisphere. A comprehensive analysis shows that the area may have shifted from a sink to a source of greenhouse gases, bringing a longtime prediction to fruition.

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.
