Carbon sink models need nitrogen, says study

Nitrogen is necessary when predicting how land plants will take up atmospheric carbon. That's because nitrogen's future trajectory will diverge from that of other factors of plant growth in the coming decades, according to ...

Do volcanoes add more carbon than they take away?

In a new study published in the Journal of Geophysical Research: Biogeosciences, Zhong and colleagues discovered that a volcano in northeast China emits a small net amount of carbon each year. Over geological timescales, ...

Researchers cultivate microalgae for biofuel production

A group of researchers at the State University of Campinas (UNICAMP) in Brazil have grown microalgae under controlled conditions in a laboratory in order to use their metabolites, especially lipids, with the prime purpose ...

Smelly seaweed bloom heads to Florida

A large mass of Sargassum "seaweed" circling around the Gulf of Mexico may soon wash up along the U.S. coast near Florida—depending on the right combination of currents and wind. The bloom, which may likely be the largest ...

Quantifying carbon leakage from enhanced rock weathering

A technique known as "enhanced rock weathering" may help remove carbon from the atmosphere, and a model shows the method will only leak minimal carbon if its products are stored in the ocean. Constraining the planet below ...
