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.

Organic Matter in Arctic River Shows Permafrost Thaw
Samples from two waterways in northern Siberia—the main stem of the Kolyma River and a headwater stream in the river’s watershed—indicate the differing sources and ages of carbon they contain.
