24 - Havenes forsuring

Kilde : IPCC 24 Forsuring af havene iflg. RCP scenarier (pH) Havenes forsuring
Set 2 www.climatefresk.org 24 Når havvand optager CO 2 , reagerer gassen med H 2 O og danner syre - ioner (H 2 CO 3 og HCO 3 ), som får vandets pH - værdi til at falde. Dette medfører en forsuring af havene.

CO2-udledninger

CO2-udledninger

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

CO2-koncentration (ppm)

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

Havtemperaturerne øges

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.
