24 - Acidificação dos oceanos

Fonte: IPCC 24 Acidificação dos oceanos de acordo com os cenários do RCP (pH) Acidificação dos oceanos
Set 2 www.climatefresk.org 24 Quando o CO 2 se dissolve no oceano, ele se transforma nos íons ácidos H 2 CO 3 e HCO 3 - . O efeito dessa transformação é a acidificação do oceano (o pH diminui).

Emissões CO2

Emissões CO2

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

Concentração de CO2 (ppm)

Players often identify CO2 concentration as a cause for ocean acidification. But it is more logical to link back to carbon sinks.
Aumento da temperatura da água

Aumento da temperatura da água

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.
