This tool from Climate Central lets you see how coastal areas will look if global temperatures increase by 2°C or 4°C.

 

The image above is Lower Largo in Fife. Areas that would be flooded by high tides are shown, with safe areas blocked out in grey. At 2°C this prediction shows flooding at the west end of the main street. At 4°C most of the main street is at risk.
