Question 4

An infrastructure planning agency compares two climate-model projections for conditions 80 years from now. Sea-level change is measured relative to the present day.

Atmospheric conditionGlobal average temperature / °CSea-level change / cm
Carbon dioxide and methane stay at present levels15.6+25
Carbon dioxide and methane levels increase17.0+60

Using the information in the table, describe two potential effects of increased levels of carbon dioxide and methane. Explain how the increased levels lead to the difference in sea-level change predicted by the model.
