Calcification of the Arctic coralline red algae Lithothamnion glaciale in response to elevated CO2

The calcium carbonate skeleton of a coralline red alga was estimated to become highly vulnerable to dissolving at an aragonite saturation state between 1.1 and 0.9, which is projected to occur in some parts of the Arctic between 2030 and 2050 if carbon emissions follow “business as usual” scenarios.
