SEA LEVEL! EVERYONE PANIC!

Well, I see that the climate hypemeisters are at it again. Here’s Google News on the subject.
Figure 1. The usual, from the usual suspects.
So I thought I’d take a look at some of the claims. To start with, here’s an overview of the sea level rise around the US coasts.

A few notes of interest. First, look at the east coast / west coast differences in relative sea level rise. This is generally not because sea levels are rising at different rates on the east and west coasts. It’s because the land is generally sinking on the east coast and rising on the west coast. Nothing to do with the ocean.
Next, check out the local differences. At Grand Isle, Louisiana, the big red arrow in the Gulf of Mexico, the relative sea level is rising at 9.2 mm per year … while only a short distance away, the green arrow to the right of Grand Isle shows that Pensacola, Florida has a relative sea level rise less than a third of that, 2.7 mm per year.
Why different sea level rise rates? Again, it has nothing to do with the ocean. It’s because Grand Isle is a silty barrier island in the Mississippi Delta, and like all such islands, it’s slowly sinking into the briny blue.
