Question

Using the diagram, predict what would happen if oceans became less able to absorb carbon dioxide due to rising temperatures. Which chain of events is most likely?

(1 point)

More CO₂ would remain in the atmosphere, increasing global warming and further reducing ocean absorption.

Less CO₂ would remain in the atmosphere, causing plants to stop photosynthesis.

Animals would release less CO₂ because the ocean stores it.

Fossil fuel use would decline naturally because of higher CO₂ levels.

Answer 1

More CO₂ would remain in the atmosphere, increasing global warming and further reducing ocean absorption.

This creates a positive feedback: warmer air/oceans hold less CO₂ (and reduce biological uptake), so atmospheric CO₂ rises, causing more warming and further reducing ocean uptake.
