Seaports With Sea Level Change - 16

Talk Talk
The Permanent Service for Mean Sea Level (PSMSL) keeps records of sea level change (SLC) around the world.

Today's post is an update of their latest data (July 19, 2021).

The previous post in this series detailed seaports and sea level changes there.

Today's post is limited to the sea level changes (sea level rise and fall) that are clearly taking place along the coastlines of the many nations where those seaports are now located.

The previous post covered this issue too (Seaports With Sea Level Change - 15), but I thought I would update that post with more recent PSMSL data.

For those who do not frequent Dredd Blog posts, and who still entertain the idea of the oceans being like a "bathtub" in the sense of having a uniform sea level, I will provide some links with contrary revelations.

As professor Jerry Mitrovica said, "nothing could be further from the truth."

Obviously sea level rises and falls before our very eyes every day in the form of high and low tide (bathtubs don't do that do they?).

The graphs show that some areas have varying degrees of sea level rise while other areas have varying degrees of sea level fall (Appendix: A-C, Appendix: D-G, Appendix: H-L, Appendix: M-O, Appendix: P-T, Appendix: U-Z).

I am not talking about tides, which they also have, I am talking about long range rising and falling of sea level.

This is caused by the melting of the Cryosphere in areas near the oceans.

Those areas such as Greenland, Antarctica, and Glacier Bay (Alaska) have sufficient mass and gravity to pull the ocean toward them, thereby raising the ocean level there.

As those areas melt, their mass and gravity diminishes so they lose their hold on that water, and it flows away from them causing sea level fall there and sea level rise elsewhere (The Bathtub Model Doesn't Hold Water, 2, 3).

Plus, thermal expansion is not 'the' or 'a' major cause of sea level change (The Young Old Sea Level Change Hoax). 

And finally, the sea level change estimates in general have been based on inaccurate ground level data (Global vulnerability to sea level rise worse than previously understood) not to mention 'the wobble' (A 'wobble' in the moon's orbit could result in record flooding - blaming the moon eh?).

So, check out the video below (a presentation by Professor Mitrovica).
