Short summary
We carried out a 1-year experiment on coralline algae to test how higher CO2 and temperature might change the mineral composition of the algal skeleton. We expected there to be a decline in magnesium with CO2 and an increase with temperature. We found that CO2 did not change the mineral composition, but higher temperature increased the amount of magnesium.
