Geological time

In our everyday life, we have no feeling for geological time. When life appeared on the planet, everything was liquid. Becoming more solid and developing symmetry gave us the opportunity to direct our movement. We tend to think of the earth – the planet earth – as something stable + unchanging. But it is not. It is transforming constantly.

For example, the last glacial maximum was a period 18,000 years ago with much larger ice sheets than what we have today. As there is limited data from that time, we can use a model to create a physically consistent description of the climatic conditions and ice sheet state at that time. The model solves the equations at discrete points on the grid.
