I have spent 55 years in the engineering profession where ignoring the evidence often kills people. Thus I am predisposed to look at the evidence before drawing conclusions.
Many articles and claims about sea levels are in conflict with the evidence.
For instance, sea level has been rising at something between 2 and 3 mm per year since the end of the Little ice age. As you can see from the graph, there is no indication that the rate of sea level rise is increasing. There is some indication that the rate of rise has reduced slightly since 2006.
In addition, the Australian Bureau of Meteorology set up a chain of sea level measuring stations around Australia and in the Pacific that are the most accurate in the world. As you can see from the chart, the sea level at Tuvalu dropped markedly during the 1997 – 1998 El Niño and since 2000 it has been substantially constant. Claims that Tuvalu is sinking beneath rising sea levels caused by man-made carbon dioxide therefore cannot be true. it is most unfortunate that many people who choose to spread this rumour have not bothered to look at the data. It is particularly unfortunate for the population of Tuvalu because they have been told that their very real problems with erosion are beyond their control when, in fact, they have largely caused them by taking too much fresh water out of the water table and by mining the reef for coral to reclaim land. If the powers that be recognised that this is the case, then aid could be concentrated on solving the real problems, not the imaginary ones.

Others claim that Pacific Islands are disappearing. Once again, this does not stack up against the evidence:
