Change in sea level 1970–2008, relative to the sea level in 1990
The solid lines are based on observations smoothed to remove the effects of inter-annual variability (light lines connect data points). Data in most recent years are obtained from satellite-based sensors. The envelope of IPCC (2001) projections is shown for comparison; this includes the broken lines as individual projections and the shading as the uncertainty around the projections.
