The research was carried out by staff at Maynooth University.
The sea level around Dublin has been rising at a faster rate in recent years.
Researchers have been looking at sea level trends over 8 decades.
The overall trend shows increases of around 1.1 millimetre a year between 1953 and 2016.
They rose at a rate of 7 millimetres per year between 1997 and 2016.
Why sea levels are rising higher than expected in Dublin and Cork. New research from @ger_the_sea @KatherineD365 @ShoarinejadA @aparnellstats @ICARUS_Maynooth @MU_Hamilton @Maynoothgeog @MaynoothUni @ZoeRoseby @tcddublin https://t.co/V2Yn3qfxUD

The study finds the increase in Dublin is faster than expected.
The rise in Dublin's sea level is also double the rate of global sea level rises.
40% of the Irish population live within 5km of the coast.
Climate change experts believe global sea level height will increase by 1 metre by 2150.
