Nitrogen fixation key to ocean life

How do ocean gardens grow? Specifically, how do those gardens get nitrogen, which is critical to producing life, and will nitrogen sources to the ocean in the future be different as the ocean changes?

Letting farmland recover may let air quality recover, too

The USDA's Conservation Reserve Program (CRP) promotes sustainable agricultural practices to improve habitat, soil and water quality. It may have an unintended benefit of improving air quality, too, according to new research ...

In forests, past disturbances obscure warming impacts

Past disturbances, such as logging, can obscure the effects of climate change on forest ecosystems. So reports a study just published in the Proceedings of the National Academy of Sciences. The paper, exploring nitrogen dynamics, ...

How grasslands respond to climate change

"Based on field experiments with increased carbon dioxide concentration, artificial warming, and modified water supply, scientists understand quite well how future climate change will affect grassland vegetation. Such knowledge ...

Paris soil carbon sequestration goals called unrealistic

The goal to offset rises in atmospheric greenhouse gas concentrations by increasing soil carbon storage by 4 per mille (0.4%) per year is unrealistic, say scientists from The Netherlands, The United Kingdom and the United ...
