From his June 4, 2008 speech on winning the Democratic primaries:
Here’s the proof: Ten year running mean sea level rise from satellite altimetry.
Figure 1. Decadal (overlapping) rates for sea level rise as determined from the satellite sea level rise observations, 1993-2011 (data available from http://sealevel.colorado.edu/).
