24 - Havsförsurning

Källa: IPCC 24 Havsförsurning enligt RCP - scenarios (pH) Havsförsurning
Set 2 www.climatefresk.org 24 När koldioxid löses upp i haven, omvandlas det till syrajoner (H 2 CO 3 and HCO 3 - ). Detta leder till en försurning av haven (pH - halten minskar).

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

Koldioxidhalt (ppm)

Players often identify CO2 concentration as a cause for ocean acidification. But it is more logical to link back to carbon sinks.
Ökning av vattentemperaturen

Ökning av vattentemperaturen

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.
