The sea level has been remarkably stable for a couple thousand years.Sea level has been remarkably stable for the last 2000 -3000 years, during which time we have built a lot of expensive infrastructure on the shoreline. Since it has been shown that mechanisms exist to drive sea level up or down hundreds of feet, should we be pushing so hard on the "rise" button?
Why don't you put all this in a reply to your twitter master and see what he says?
Its remarkably stable now.
Your chart shows a sea level rise of roughly 8 inches in the past 136 years.
Well below average over the last 20,000 years.
How are you going to prove the "hundreds of feet", and how are you going to link it to AGW?
