Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air.

Tiny cyanobacteria may be the secret heroes of ocean carbon sequestration

A process known as the biological carbon pump (BCP) moves organic carbon from near the ocean's surface to the ocean floor. That carbon often stays there for hundreds or thousands of years, making the BCP a primary source of carbon sequestration in the oceans.
