Long-Lost Records Confirm Rising Sea Level

It amazing that people think this is not a problem, despite the immense amount of evidence that sugests we are destroying our planet.

Oh really? You think rising sea level is an unprecedented problem? You think it's changing at historic rates?

I am pleased to disabuse you. Here is the fossil record from historic reef dieoffs due to historic catastrophic changes in sea levels:

Ref Journal: Geology, a publication of The Geological Society of America

Blanchon, Paul, John Shaw, 1995: Reef drowning during the last deglaciation: Evidence for catastrophic sea-level rise and ice-sheet collapse. Geology: Vol. 23, No. 1, pp. 4–8.

As you can see from the chart (and contrary to your programmed wailing), we are now experiencing an historically SLOW rate of change in sea level. So, before you go believing the popular whizdumb, perhaps you had best learn to gather a few hard facts, else you will serve the intents of the purveyors of this snake oil.

How could a "rudimentary tide gauge" be trusted to make minute measurements on a moving body of water at the sea shore?

There are ways that this could be 'reliable' - over many measurements over a long period of time ... though the use of some relatively simple statistical tricks. Wave action will be predictable (insofar as peak and valley hights) and occur with regularity - given some measurements averaged over several minutes an average 'value' of height (depth) can be determined.

How accurate can this be made? That's the 64,000 dollar question. Today, through the use of modern position transducers and averaging over a statistially large number of samples I could come up with a very accurate, repeatable value.
