Scientists who claim that huge sea level rises will occur in some places – but not others – are simply flaming morons. Water is a fluid. If the WAIS “collapses” and raises sea level by two metres, then sea level will rise by two metres everywhere.
The reason we see discrepancies in sea level data now are because the numbers we are working with are small. One place may have 3 mm of rise while another place may have 3 mm of fall, due to thermal expansion, wind, instrument error, subsidence, etc.
If we saw an actual sea level rise of thousands of millimetres, it would be nearly uniform across the planet. Try making the water at one end of your swimming pool stay higher than at the other end.
People are getting PhD’s in science from universities, while lacking science skills needed to graduate high school.
