Soil Carbon May Not Remain Bogged Down in a Warmer World
Carbon was lost from an experimentally warmed boreal peatland much faster than it took to accumulate. Elevated CO2 had little effect on stored carbon, requiring re-evaluation of model assumptions.

Eruption and Emissions Take Credit for Ocean Carbon Sink Changes
A new model explains why the ocean’s capacity to take up carbon was reduced on a decadal scale, by accounting for reduced pCO2 emissions and ocean state changes due to the eruption of Mt. Pinatubo.
