Projected sea level change in Venice in the context of historical observations ENG.jpg

Projected sea level change in Venice in the context of historical observations. Observations are annual-mean tide gauge relative sea-level (RSL) height anomalies with respect to the 2000-2007 average. Projections are based on two reference scenarios of anthropogenic greenhouse gas emission, namely RCP2.6 (low emission scenario) and RCIP8.5 (strong emission scenario), and a high-end scenario illustrating a plausible evolution obtained by combining the highest estimates of all individual contributions to relative sea level rise. The horizontal blue lines shows the annual persistence of the sea level above the present safeguard level as a function of future relative mean sea level. These time intervals approximately correspond to the annual duration of the expected closures of MoSE.
