To predict Arctic Sea-Ice we use a large computer to run a model of the real world.
The model uses our understanding of the science (physics) of how ice and ocean behave on the Earth.

We give the Arctic model wind and air temperature information from weather forecasting models, and it computes how the ocean and the sea-ice react.
This picture shows the thickness of sea-ice in the Arctic Ocean according to the model.
