Cracking Soils Could Accelerate Climate Change
Climate change is expected to lead to more frequent and intense drought, which in turn causes soil to crack, releasing more carbon dioxide and further warming the planet.

Extra Carbon Dioxide Helps Lower Layers of the Amazon Thrive—for Now
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.
