Follow up question, how do they measure the sea level?

NOAA can use satellites that send down signals and measure the time it takes for it to bounce back. Same idea as a laser measurer you might use around the house, only a lot more lasers in a lot more places over a long period of time

Take a bunch of measurements all over the world and do a weighted average.
