A new review synthesizes VOC sources, occurrence, analytical methods and climate feedbacks in the Tibetan Plateau and polar regions. On the analytical side, the authors report that gas chromatography–mass spectrometry (GC–MS) remains the most widely applied technique for…
A University of Bath-led study has estimated that the carbon dioxide produced by humans as our bodies turn food into energy rose by 74% between 1985 and 2015, reaching 2.05 billion tonnes a year. Researchers from the University's Centre for Exercise, Nutrition and Metabolism…
Two adjacent fields in Jiangxi Province, China, grow different crops — one peanuts, one rice. Published February 27, 2026 This article predates the current owners of Science Blog. It has not been reviewed under the current editorial process and is kept as part…
A research team has uncovered strikingly different effects of biochar on nitrous oxide (N₂O) emissions from acidic agricultural soils, showing that while biochar can significantly reduce emissions in upland fields, it may sharply increase them in flooded paddy soils. Biocharâs…
Divergent pathways of straw versus biochar integration with manure to enhance SOC sequestration in coastal saline soils EurekAlert! Divergent pathways of straw versus biochar integration with manure to enhance SOC sequestration in coastal saline soils Xiaolong Bai, Jie Zhou, Ruixiao…
Soils are among the planet's largest carbon reservoirs, yet salinity and land degradation threaten their ability to store carbon and support agriculture. Improving carbon storage in salt-affected farmland could therefore offer a dual benefit: restoring soil health while supporting climate…
As a result, the natural balance between carbon emissions and absorption has been disrupted, contributing to rising global temperatures and widespread environmental changes. CO2 is a greenhouse gas, meaning it absorbs and re-emits infrared radiation from the Earth’s surface. This natural…
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to…
The chemistry of methane, nitrous oxide and other greenhouse gases: where they come from, what removes them and how they react in the air.
