claim: If Hillary would have fact-checked her example of sea level rise in Norfolk, Virginia, she would have found out that the experts already know this is mostly due to the land there sinking.
evidence: Some land masses are moving up or down as a consequence of subsidence ( land sinking or settling ) or post-glacial rebound ( land rising due to the loss of the weight of ice after melting ), so that local sea level rise may be higher or lower than the global average.
