Ecosystem productivity shapes how soil microbes store or release carbon, challenging old assumptions
Soils store more carbon than the atmosphere and vegetation combined, with soil microorganisms playing the main role. As a result, the global soil carbon cycle—by which carbon enters, moves through, and leaves soils worldwide—exerts a…

Ancient CO₂ surge triggered widespread forest fires and erosion 56 million years ago
The climate warmed up almost as quickly 56 million years ago as it is doing now. When a huge amount of CO2 entered the atmosphere in a short period of time, it led to large-scale forest fires and erosion. Mei Nelissen, Ph.D. candidate at NIOZ and…

What deep sea mud is revealing about giant earthquakes along the Pacific Coast
Marine turbidites are layers of mud and sand deposited on the deep ocean floor by massive underwater landslides and are often used as a historical record for reconstructing earthquake histories.
