Phys.org / 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. ...

Phys.org / 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 ...
