According to ESA, Sentinel-6, one of the most advanced altimetry satellites, has a sea surface height measurement accuracy of <4 cm. NASA echoes similar numbers, claiming satellite altimetry achieves 2.5 to 4 cm accuracy over the global oceans.
So let’s be clear: they’re detecting micron-scale accelerations using instruments with centimeter-scale noise. That’s a factor of 1,000 between the noise and the signal. Even with years of averaging, extensive noise filtering, and meticulous data modeling, this veers between pseudoscience at best and scientific fraud at worst. //

3/ The analysis is based on thousands of measurements from satellites, and uncertainty decreases with =SQRT(N). So the measurement error is much larger than the error of the mean GMSL value. With your Ph.D. in earth science, you certainly learned this. You're being dishonest.
