Why is there a range in climate model results?

The future is uncertain, and we don’t know exactly what it will look like. The main causes are: not knowing how greenhouse gas emissions may evolve in the future, how models simulate natural climate variability (known as internal variability) and inter-model differences.

Emissions scenarios allow us to view different ‘what if?’ questions to help us plan for the future.
