What evidence would you present to convince a skeptic that sea level is rising?
What will be an ideal response?
First, I would concentrate on relevant evidence found along shorelines away from plate boundaries where uplift or subsidence may cause the appearance of sea level change that is not really a global phenomenon. I would also avoid locations near river deltas where sediment accumulation may cause a local building out of the shoreline that gives the impression of a sea-level fall.
Concentrating on locations that meet these requirements, I would use tide-gage data to identify long-term trends of sea-level change (unaffected by year-to-year weather conditions) and find historic photographs of shorelines that I could compare to what the shoreline looks like today.
