Measuring soil carbon flux, also known as soil respiration, can be expensive or time-consuming. A set of affordable robots that gather these data autonomously could especially benefit the Global South.
New research upends the notion that the weathering of rocks mainly removes CO2 from the atmosphere. Rocks can also be carbon sources, releasing as much CO2 as Earth’s volcanoes.
Carbon cycle models quantify relationships between emission scenarios and resulting atmospheric concentrations, but are the projections credible? New analyses find grounds for both hope and concern.
Movement of carbon from land to ocean and atmosphere plays an important, but understudied, role in the global carbon cycle.
Новое исследование показало, что арктические реки в настоящее время переносят ограниченное количество растворенного органического углерода из вечной мерзлоты, что имеет значение для понимания изменения углеродного цикла в регионе и его потенциальной возможности ускорить изменение климата.
The array of processes and organisms that make up the biological carbon pump has immense influence on Earth’s carbon cycle and climate. But there’s still much to learn about how the pump works.
Underrepresented in global carbon budgets, tropical rivers like Brazil’s Tocantins are in need of study to establish their baseline characteristics in the face of increasing global change.
Cooler and saltier than even the water just below it, the ocean skin plays a critical role in ocean-atmosphere gas exchange.
The color of soil reflecting the Sun’s rays affects the Earth’s climate and water cycle. Using satellite data that senses many wavelengths improves soil reflectivity estimates, especially in deserts.
New research suggests that mycorrhizal fungi take in 13 billion tons of carbon dioxide annually, playing a prominent role in Earth’s carbon cycle.
