Rising levels of atmospheric carbon dioxide (CO2) is one of the main causes of climate change.  One problem with this is that it is indirectly causing damage to coral reef ecosystems.  Which scientific reasoning explains why?

• Carbon dioxide is dissolved in the ocean lowering its pH and making it more acidic

• Carbon dioxide is dissolved in the ocean raising its pH and making it more basic

• Carbon dioxide is dissolved in the ocean lowering its temperature

• Carbon dioxide is dissolved in the ocean raising its temperature
