I have no issue believing you can measure sea levels at certain places. The question is, how do you mix all those measurements together to determine a global sea level number?
Afaik many things affect local measurements, like storms and tides.
For example, if you measure at three points in the US, and one point in Japan, how are the measurements weighted?
Suppose a storm is blowing in the US, increasing the measurements by 1m. How is it being accounted for?
If they tapped me with their propaganda about rising sea levels, I would ask 'scientists' this question:
Seeing that tides vary from 5 to 25 feet all over the world and waves in similar ranges routinely pound shorelines, how is it that you claim to be able to measure ocean levels to within a fraction of an inch?
Is it even solid science to measure sea levels over 2 months? How do you measure "sea level"? It seems normal that ice melts as summer comes around. So there would be fluctuations in sea level? How do they account for all the possible variations to establish a sea level number?
