11 Fuente: IPCC 1100 ppm 280 ppm 400 ppm 415 ppm Concentración de CO 2
Set 2 www.climatefresk.org 11 La mitad de nuestras emisiones de CO 2 son captadas por los sumideros de carbono, la otra mitad permanecen en la atmósfera. La concentración de CO 2 en el aire se ha incrementado de 280 a 450 ppm (partes por millón) en 150 años. La más alta en los últimos tres millones de años.

Cause

Carbon Sinks

Carbon Sinks

the card n11 represents the concentration in CO2, understood in the atmosphere (it's written behind the card).

Consequence

Additional Greenhouse Effect

Concentration of CO2 (ppm)

You can recognize the molecules of the different GHGs on the card 13 : H2O (red and white), CO2 (grey and red), CH4 (grey and white), nitrious (blue and red).

Wrong cause

CO2 Emissions

CO2 Emissions

Why not, but better link card 12 (Carbon sinks) to card 11. Card 12 is meant for that.

2
Wrong consequences

Carbon Sinks

Concentration of CO2 (ppm)

It can be argued that CO2 emissions take place before reaching carbon sinks. But the opposite link has our preference.
Ocean Acidification

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.
