A coastal bird reserve has three nesting areas.
| Nesting area | Height above present mean sea level in m |
|---|---|
| A | 0.20 |
| B | 0.50 |
| C | 0.85 |
Two climate models make different predictions for the reserve.
| Climate model | Predicted rise in global average temperature in °C | Predicted rise in mean sea level in m |
|---|---|---|
| 1 | 1.5 | 0.30 |
| 2 | 3.0 | 0.65 |
An area is predicted to be flooded if the predicted rise in mean sea level is greater than its height above present mean sea level.
Use the data to explain which nesting areas are predicted to be flooded in each climate model. Explain why the greater temperature rise in climate model 2 is linked to a greater rise in sea level.
