24 - Ocean Acidification

Sorga : GIEC 24 Acidificacion de l’ocean en fonccion dels scenaris SSP (pH) Acidificacion de l’ocean
Set 2 www.climatefresk.org 24 Quand lo CO 2 se disòlv dins l’ocean , se transfòrma en d'ions d’acides (H 2 CO 3 puèi HCO 3 - ). Aquò a per efièch d’acidifiar l’ocean (lo pH baissa )

The word "Ocean" is written on both sides.

Wrong causes

CO2 Emissions

CO2 Emissions

Why not but rather link Card 12 (Carbon sinks) to card 24. It is meant for it.
Concentration of CO2 (ppm)

Concentration of CO2 (ppm)

Players often identify CO2 concentration as a cause for ocean acidification. But it is more logical to link back to carbon sinks.
Rising Water Temperature

Rising Water Temperature

The increase of water temperature is not linked to ocean acidification, at least for the time being. In the long term (over several centuries), as it heats up, the water will lose its capacity to dissolve atmospheric CO2 and will become less efficient as a carbon sink. So the increase in water temperature will inhibit, to some extent, ocean acidification.
