Plants living in the shadows grew faster when exposed to excess carbon dioxide. But this short-term effect could vanish in a high-emission-induced warmer future, making the forest a carbon source.

Planting Trees May Not Be as Good for the Climate as Previously Believed
The climate benefits of trees storing carbon dioxide is partially offset by dark forests’ absorption of more heat from the Sun, and compounds they release that slow the destruction of methane in the atmosphere.

The Open Ocean, Aerosols, and Every Other Breath You Take
Phytoplankton and other marine plants produce half of Earth’s atmospheric oxygen and have big effects on food webs and climate. To do so, they rely on nutrients from the sky that are hard to quantify.

A Transformative Carbon Sink in the Ocean?
Water-rock reactions in some hydrothermal systems produce both hydrogen, which could be tapped for clean energy, and alkaline solutions that could help draw down atmospheric carbon dioxide.

Nutrients at Depth Can Be Uplifted by the Kuroshio Large Meander
Aperiodic, southward deflection of the Kuroshio, a.k.a. the Kuroshio large meander, uplifts the nutrients in deep layers to induce offshore phytoplankton bloom.
