      - Lessen goals 

      - Planning 

      - Climate research 

      - Assigments 

      - Closing 

Lesson goals 

You'll learn to

- Explain how ice-core data is used. 

- Use annual rings, pollen, landscapes, layers in the ground and Fossils to explain climate change. 

- Use these data sets to make a statement within the climate debate. 

Climate research 

Data and Models

- Annual rings 

- Pollen 

- Landscape 

- Ice cores 

- Layers in the ground 

- Fossils 

Annual Rings 

Dendrochronology

Annual?

What do the rings tell us?  

What is the oldest ring of a tree?

Old trees 

Old log-cabins 

What does the withe of an annual ring tells climate scientists?

Pollen 

- Higher temperature 

- More pollen 

- More pollen found in the:

      - Ice 

      - Ground 

      - Sediments 

Landscape 

Hills, valleys and other forms of landscape are indications of the previous climate 

- Veluwe 

- Utrechtse heuvelrug 

Stuwwallen

Relief

Pingo

Underground water freezes and expands. 

Pingo

Pingo ruin

Ice cores 

Co2 is stored within the tiny air bubbles in the ice

Ice core data goes back 740.000 years 

(Antarctica) 

Layers in the ground & Fossils 

Not the most accurate 

It's a time capsule not a linear scale 

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? 

Climate change or Climate stability?

Closing 

To know:

     - Different methodes for measuring the climate 

     - Accurate or not?

   

To do:

     - Make assigments of 3.7 (MS-teams)
