Ice cores 
Co2 is stored within the tiny air bubbles in the ice

Ice core data goes back 740.000 years 

(Antarctica) 

Slide 17 - Diapositive

Layers in the ground & Fossils 
Not the most accurate 

It's a time capsule not a linear scale 


Slide 18 - Diapositive

Climate scientists use dating 
- Dating of stacked layers (ice cores, annual rings, pollen)

- Make a climate chart and use the different aspects 

- Is climate change normal? 

Slide 19 - Diapositive

Climate change or Climate stability?
