Glaciers Offer Clues into the Path of Fossil Fuel Pollution

by Rebecca Owen 28 April 20255 May 2025

New research traces the origin of carbon deposited from the atmosphere onto glaciers.

Dry Heat, Wet Heat, and Wetland Methane Emissions

Aaron Sidder, freelance science writer by Aaron Sidder 20 November 202420 November 2024

Compound weather events—such as extreme cold or heat combined with severe dryness or precipitation—have a greater effect on wetland methane emissions than discrete weather extremes do.

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.

Each Glacier Has a Unique Organic Matter Composition

by Saima May Sidik 15 October 202415 October 2024

Like snowflakes, no two glaciers are alike: Carbon-containing compounds released from glaciers vary from place to place, meaning climate and ecosystem effects of melting could vary as well.

Scientists Present Europe’s New Greenhouse Gas Budget

Aaron Sidder, freelance science writer by Aaron Sidder 3 September 202414 February 2025

The greenhouse gas budget developed for Europe highlights carbon sources and sinks across the continent and will serve as a baseline for years to come.

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.

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.
