Grow-Fast-Die-Young Strategy Increases Swiss Forest Biomass
Climate change and CO2 fertilization can increase both growth and mortality of trees. The net effect on forest biomass depends on that trade-off, which long-term studies in Switzerland reveal.

Our Evolving Understanding of Biological Carbon Export
The array of processes and organisms that make up the biological carbon pump has immense influence on Earth’s carbon cycle and climate. But there’s still much to learn about how the pump works.

A Multidecadal View of Oceanic Storage of Anthropogenic Carbon
A decline in the ratio of ocean carbon accumulation to atmospheric carbon dioxide growth between 1994-2004 and 2004-2014 suggests a reduction in the sensitivity of the ocean carbon sink.

Ambidextrous Microbes May Pump Out CO2 as Temperatures Rise
Certain microbes that engage in both photosynthesis and predation are more likely to do the latter as the planet warms, resulting in a net release of carbon dioxide.
