Question 3

A city planning commissioner consults with climate scientists to assess the impact of sea level rise on strategic infrastructure projects. The scientists discuss several climate model projections and indicate sea level rise has a fundamental relationship to GHG emissions, regardless of a specific warming scenario.

How should the scientists describe this relationship?

Sea level rises proportionally faster than GHG emissions.

Sea level rise lags GHG emissions.

Sea level rises in response to ocean acidification.

Sea level rise will cease once global emissions peak.

Correct Answer: B

Sea level rise lags GHG emissions. This is because greenhouse gas emissions contribute to global warming, which in turn leads to the melting of polar ice caps and the thermal expansion of seawater. However, these processes take time, so the rise in sea levels occurs after the increase in GHG emissions.
