Methods and models
It's a well-known fact that the ocean is one of the biggest absorbers of the carbon dioxide emitted by way of human activity. What's less well known is how the ocean's processes for absorbing that carbon change over time, and how they might affect its ability to buffer climate change. (2019-06-19)

Nano-saturn
Saturn is the second largest planet in our solar system and has a characteristic ring. Japanese researchers have now synthesized a molecular 'nano-Saturn'.

Carbon feedback from forest soils will accelerate global warming, 26-year study projects
After 26 years, the world's longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundant carbon release from the soil to the atmosphere alternating with periods of no detectable loss in soil carbon stores. The study, led by Jerry Melillo of the Marine Biological Laboratory, indicates that in a warming world, a self-reinforcing and perhaps uncontrollable carbon feedback will occur between forest soils and the climate system, accelerating global warming.
