25 years of Multi-mission global sea level trend from altimetry (1993-2017) based on ESA’s Climate Change Initiative Project (SL_cci) from 1993 to 2015, extended (in red) by multi-mission data processed by CNES (AVISO) until mid-2017 and further extended by Jason-3 "near real time" data up to 22 November 2017 (NB: the Topex-A drift correction has been applied on the 6 first years). The curve has been corrected for the GIA effect. The global mean sea level has increased by about 3 mm/yr on average but the black curve (a quadratic function fitted to the data) shows clear acceleration over the recent years. The objective of the ESA Sea Level Climate Change Initiative project is to provide stable, long-term satellite-based Sea Level products for climate applications.
