What makes u think that is abby normal ? What if the data exists that shows it is normal and has occured before?

3mm per year = 30cm in 100 years. That's nothing to worry about and might not continue with global cooling and Antarctic ice cap increase. Far more worrying than 3 mm per year or 30 cm in 100 years is 10 metres in 1 second as experienced in Japan not long ago.

< For the period 1961-2003, the observed sea level rise due to thermal expansion was 0.42 millimeters per year and 0.69 millimeters per year due to total glacier melt (small glaciers, ice caps, ice sheets) ( IPCC 2007). Between 1993 and 2003, the contribution to sea level rise increased for both sources to 1.60 millimeters per year and 1.19 millimeters per year respectively ( IPCC 2007).>

30 cm in a century is inconsequential.

You might want to look at later statements from the IPCC.









Thermal expansion is one third smaller in AR5 and land water storage with a substantial amount is
completely new in AR5, while the sum of these sources remained constant. With regards to land water
storage, a recent paper(5) estimated that the human impacts, particularly unsustainable ground water use,
have contributed a sea-level rise of about 0.77?mm?yr-1 between 1961 and 2003, which is twice as
large as the estimate used in the AR5.
