Read here and here. Although the recent sea level rise has been non-existent, the modern past, per the satellite estimates, has seen it rising about 3mm per year (about 12 inches per century). A new peer-reviewed study has determined that at least 25% of the past increase has been due to groundwater extraction, not CO2-induced warming. The IPCC climate models completely ignore this human-caused (groundwater extraction) component of sea level increases.
"Large-scale groundwater extraction for irrigation, drinking water or industry results in an annual rise in sea levels of approximately 0.8 mm, accounting for about one-quarter of total annual sea-level rise.....“We calculated it at eight-tenths of a millimetre per year. This is surprisingly large when compared to the current annual rise in sea levels, which the IPCC estimates at 3.1 mm.”..... Our study confirms that groundwater depletion is, in fact, a significant factor.”"
