I THINK this might be the explanation:

Warm water expands more than cooler water. If the Atlantic on the Eastern Seaboard is warmer, the water there will be “bigger.” Yes this bigger water will flow out of the Atlantic and cool elsewhere, but cooler water will then also flow into this warm zone and expand again, keeping the water level constantly higher.

Don’t hate me— I’m just trying to clarify what I think the theory is.

Warm water expands

Best info I could find is that in a hot water tank, volume increase half gallon in a 40 gallon tank from 90 degrees to 140 degrees, that is .013 percent. NOTE THAT IS A 50 DEGREE INCREASE. Some one with better math skills can work this out for ocean volume increase for ocean for 1 degree. then convert volume increase to sea level increase.

In searching for “how much does water volume increase for every temp degree increase” the answer from a lib site was 9% which is the increase in volume for water freezing. facts don't matter to libs.
