An emergency planning service is preparing for severe storms in a coastal region.
The current mean number of severe storms each year is 4.
Three climate models predict the mean number of severe storms each year in 2070.
| Climate model | Predicted mean number of severe storms each year in 2070 |
|---|---|
| P | 6 |
| Q | 8 |
| R | 11 |
Explain why the service should prepare for a greater number of severe storms, and why the exact mean number per year in 2070 cannot be predicted.
