A new study published today in Nature Climate Change is the first to analyse global sea-level rise combined with measurements of sinking land.
The impact of subsidence combined with sea-level rise has until now been considered a local issue rather than a global one.
But the new study shows that coastal inhabitants are living with an average sea level rise of 7.8 mm - 9.9 mm per year over the past twenty years, compared with a global average rise of 2.6mm a year.
And the impacts are far larger than the global numbers reported by the Intergovernmental Panel on Climate Change (IPCC).
