Using Tree Rings for Past Weather and Climate

Using tree rings to teach weather, climate, correlation, photosynthesis, regression, the carbon cycle, isotopes and more.

1) Show the Film

2) Play the Game

Collect tree ring samples, align the samples to create a 300 year record and see what weather and climate events emerge here.

Alternatively, use the simple paper-strip version from UCAR.

3) Choose the Relevant Teaching Resource

Dating the Past Using Stable Isotopes in Tree Rings

Past Summer Rainfall from Oxygen Isotopes in Tree Rings

Unless otherwise stated, all temperature data used in the resources are based on the dataset published in this paper: European summer temperatures since Roman times. More information about the technique can be found in this paper: Oxygen stable isotope ratios from British oak tree-rings provide a strong and consistent record of past changes in summer rainfall.
