Today’s climate crisis is unprecedented thanks to human activity.
Oceans are absorbing extremely high levels of CO2 from the atmosphere. In turn, the water is becoming more acidic and making it difficult for sea creatures to form strong bones and shells from declining levels of calcium carbonate in the water.

But a new report this week in Science shows that some may have been more resilient than we previously thought.
Coccolithophores may be at the bottom of the food chain, but they play a vital role in regulating ocean CO2 levels.
When less coccolithophore fossils are present at a certain past time period, that indicates to researchers that less calcium carbonate was present in the ocean.

That may have had to do with the resilience of phytoplankton.
