I agree, sea level is rising and has been rising for 1000s of years. What lead me to say it is not rising is my recollection from reading Michael Crichton's State of Fear, published 2004. I remember his claim as something like there is no evidence of sea level rise recently. I may be misremembering it or he may have made the claim, maybe he claimed there is no evidence for off-trend sea level rise, of accelerated sea level rise.

Whatever he claimed, I agree sea level is rising.
