Concetrația de CO 2 1000 ppm 280 ppm 410 ppm 400 ppm Sursa: IPCC 11
Set 2 www.climatefresk.org 11 Aproximativ jumătate din emisiile noastre de CO 2 sunt captate de rezervoarele naturale de carbon . Cealaltă jumătate rămâne în atmosferă . Concentrația de CO 2 în atmosferă a crescut de la 280 la 410 ppm ( părți pe milion ) în 150 de ani .

Cause

Rezervoare naturale de carbon

Rezervoare naturale de carbon

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

Consequence

Efect de seră suplimentar

Concetrația de 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

Emisiile de CO2

Emisiile de CO2

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

Wrong consequences

Rezervoare naturale de carbon

Concetrația de CO2 (ppm)

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

Concetrația 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.
