It seems your graph confirms my picture regarding the post-glacial melting. There is no debate that sea levels have risen in the past few decades, and this is accelerating. Measurements conducted by many scientific agencies are less subject to debate that just about anything. I think the figure is 8 inches. Let's see:
"Core samples, tide gauge readings, and, most recently, satellite measurements tell us that over the past century, the Global Mean Sea Level (GMSL) has risen by 4 to 8 inches (10 to 20 centimeters). However, the annual rate of rise over the past 20 years has been 0.13 inches (3.2 millimeters) a year, roughly twice the average speed of the preceding 80 years."
