Sediment reactions defy dogma
Redox reactions in widely spatially separated layers of marine sediments are coupled to each other. This suggests that bacteria mediate the flow of electrons between the layers — an idea that would previously have been dismissed.

Ensemble reconstruction constraints on the global carbon cycle sensitivity to climate
Anthropogenic global warming is likely to be amplified by positive feedback from the global carbon cycle; however, the magnitude of the climate sensitivity of the global carbon cycle, and thus of its positive feedback strength, is under debate. By combining a probabilistic approach with an ensemble of proxy-based temperature reconstructions and pre-industrial CO2 data from three ice cores, this climate sensitivity is now shown to be much smaller than previously thought.
