Eukaryotic phytoplankton drive a decrease in primary production under ocean acidification. Credit: Dalin Shi Princeton University and Xiamen University researchers report that in tropical and ...

Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems. In June 2025, a study found that ...

Learn how the carbon cycle works and how greenhouse gases like carbon dioxide and methane disrupt it, shaping climate change ...

The world’s oceans absorb approximately a quarter of all carbon dioxide (CO 2) emissions. During absorption, CO 2 reacts with seawater and oceanic pH levels fall. This is known as ocean acidification ...

As humans continue to pump the atmosphere with carbon, it's crucial for scientists to understand how and where the planet absorbs and naturally emits carbon. A recent study in the journal Nature ...

A new study examined the global carbon cycle and suggests that scientists may have misgauged how carbon is distributed around the world, particularly between the northern and southern hemispheres. The ...
