When averaged over all of the world’s oceans, absolute sea level has risen at an average rate of 0.06 inches per year from 1880 to 2013 (see Figure 1). Since 1993, however, average sea level has risen at a rate of 0.12 to 0.14 inches per year—roughly twice as fast as the long-term trend.
This indicator describes how sea level has changed over time. The indicator describes two types of sea level changes: absolute and relative.

The first graph makes the claim in its title that it shows long term levels declining. The second doesn't say and the text concerns itself with the rapid rise between 20,000 and 8,000 years ago (15 mm/yr) but by eyeball it looks to have risen 5 meters over 8,000 years or 0.625 meters/1,000 years.
Current sea level change rate is 0.12 to 0.14 inches per year. Let's call it 0.13 inches/year or 3.3mm/year or 3.30 meters/1,000 years. In eight thousand years that would be 26.4 meters, several times the rate seen in those graphs and on top of that, sea level rise is accelerating. So, your claim fails.

What I see from these curves is exactly what I said. No material change in sea level rise for the past 6,000 years.
According to your ridiculous projections of catastrophe that rate needs to triple by the end of the decade. That's not going to happen. It's beyond ridiculous.

Which, with no further acceleration, looks like 4 mm/yr. If it simply held that rate for another 8,000 years seas would be up more than 100 feet. So, I don't know where you get the idea that the rate hasn't changed in 8,000 years. That's simply nonsense.

It hasn't materially changed. You think going from 3.4 mm/yr to 4.0 mm/yr is a material change. It's not. Going to 10 mm/yr in the next 8 years and staying there or increasing as you believe it will would be a material change. It's not going to happen. Do the math. Show me your thermal expansion of water calculations.

You said: "The sea level has been rising at the same rate for the past 6,000 years. There's your evidence."
You're developing a slightly annoying habit of attempting deflection when someone points out your errors. Better idea: admit them, learn from them and move on.
