Today’s climate crisis is unprecedented thanks to human activity.

But historical climate fluctuations help researchers gauge how rising greenhouse gas levels will have a domino effect on modern ecosystems.

Take the oceans, for example.

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.
