That's great right next to an active volcano

Whch might be significant on a day to day or month to month basis, but change over decades is not going to be affected by the Hawaiian volcanoes alone.

There are plenty of expensive studies on the but who knows how accurate they will be.
For instance with global warming more water will be in the air as sea evaporates at a greater rate.Water expands when it freezes so a straight exchange volume for volume does not work etc..
There are to many variables and unpredictables for any study to be really reliable.
That`s what I tell myself anyway. Insurance companies are using one model that means that I can`t change my home insurer as no-one will take on our postcode as new business because we are too high risk of inundation from the sea.
The house is over two hundred years old and has been OK so far.
But the road is covered more often in recent years than previous records indicate and ancient houses are being flooded that have never been in the past.
This is not due to coastal erosion. It`s just that the sea is deeper.

Sea level has risen 130 meters from18,000 years ago, 120 meters of that were in the following 12,000 years, an average rate of one meter per century, seven times faster than the present rate.

Researchers report that the linear link between global mean temperature and the rate of change of global mean sea level "turned out to be not reliable over the full time period," noting that "instead, for some periods, even inverse relationships were found to describe the simulated data best." They also say that the second predictor -- the rate of change of temperature -- "did not show markedly better results." And for both predictors, they report "there exist periods in the simulation where the prediction errors are very large." Ocean Dynamics, von Storch et al. (2008)

There is currently no known way to predict with any reasonable and demonstrable degree of confidence what sea level will do over the next century, even if air temperature begins to rise once again after having remained pretty stable for the past decade.
