Hydrology Dictates Fate of Carbon from Northern Hardwood Forests
As spring snowmelt and fall rains inundate northern hardwood forests with moisture, soil bacteria get moving and increase carbon exports to the atmosphere and into nearby water bodies.

Autumn Warming No Longer Accelerating Carbon Loss in the North
An analysis of Point Barrow’s 40-year record points to the importance of calculating the carbon cycle’s response to temperature during the northern latitudes’ non-growing season.

Carbonate Melting Enhances Mantle CO2 Fluxes in Old Ocean Basins
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle.
