24 - Verzuring van oceanen

Bron: IPCC 24 Verzuring van de oceanen onder SSP - scenario's (pH) Verzuring van de oceaan
Set 2 www.climatefresk.org 24 Wanneer CO 2 in de oceaan oplost, wordt het omgezet in zure ionen (H 2 CO 3 en vervolgens HCO 3 - ). Dit heeft tot gevolg dat de oceaan verzuurt (de pH waarde daalt).

Wrong causes

CO2-uitstoot

CO2-uitstoot

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

Concentratie van CO2 (ppm)

Players often identify CO2 concentration as a cause for ocean acidification. But it is more logical to link back to carbon sinks.
Toename van de watertemperatuur

Toename van de watertemperatuur

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.
