No, it is faster than average, and the extra speed is best explained by a thermosteric rise (in addition to the ongoing melting of land ice since the last ice age) in line with the OHC rises.
The recent sharp drop in sea level is a bit troublesome as the amount of water it takes to do this by itself would cover the land masses with a couple of inches of water. That hasn't happened. Will have to wait and see if there is a rebound in the next 6 months. IF there isn't.....that opens up a lot of questions.
The drop is about 6 mm. So we're talking a half inch on land, not two. At least 6 months I reckon for the rivers to get this back to the ocean. I'm patient
I have read approx 2 inches in numerous places verses your 1/2 inch. The amount, however, is not really important.
When you look at the rate of sea level rise, where do you get the idea that it is fast now compared to 40 or even 100 years ago? I would be interested in reading a valid paper etc that shows an acceleration.
I know on the continental US, the river system is back to normal, if not slightly below normal now, so our spring melt/rain has returned. I don't know about the rest of the world. That is why I said 6 months more of data would be needed to equalize the NH spring/summer as that is where most of the land mass is.
