Tipping points in climate change

The new Earthlearningidea published today is 'Modelling tipping points – by hands; demonstrating tipping points in the Earth’s system with the hands of three people'.

This is an activity to demonstrate the concept of tipping points in climate change. Tipping points are often discussed in climate change and there are several well-known films based on the sudden change of climate to a new ice age or to much hotter conditions.
