'Global sea level has risen about 8–9 inches (21–24 cm) since 1880, but the rate of rise has accelerated significantly in recent decades, more than doubling from ~2.1 mm/year in 1993 to ~4.5 mm/year by 2023. This acceleration, driven by ice melt and thermal expansion, leads to more frequent and severe coastal flooding. Regional sea level rise varies due to factors like land subsidence, with some U.S. coastal areas experiencing much faster increases than the global average.'

Literally the first info that comes up when you type in 'sea level rise.'

Evidently typing is beyond you..
