Seaports With Sea Level Change - 9

Ports are ports
I. Review

Regular readers know that Dredd Blog has considered, for a number of years, the vulnerability of world seaports to sea level change in terms of both sea level fall and sea level rise (e.g. "The artist's painting, above, shows that the major ports would be destroyed ultimately, but will be damaged well before they become useless", Will This Float Your Boat?, May 4, 2011; Seaports With Sea Level Change, 2, 3, 4, 5, 6, 7, 8).

That reality is finding its way into the scientific literature:
"Ports are an important economic actor—at local, national, and international scales—that have been identified as being vulnerable to future changes to the climate. This paper details the findings from an international review of state‐of‐the‐art knowledge concerning climate risks, and adaptation responses, for ports and their supply chains. Evidence from both academic and gray literature indicates that there has already been major damage and disruption to ports across the world from climate‐related hazards and that such impacts are projected to increase in the years and decades to come. Findings indicate that while a substantial—and growing—body of scientific evidence on coastal risks and potential adaptation options is acting as a stimulus for port authorities to explicitly consider the risks for their assets and operations, only a notable few [port authorities] have actually made the next step toward implementing adaptation strategies. This paper concludes by putting forward constructive recommendations for the sector and suggestions for research to address remaining knowledge gaps. It emphasizes a call for collaboration between the research and practice communities, as well as the need to engage a broad range of stakeholders in the adaptation planning process."
(Implications of climate change for shipping, 2018, emphasis added). Dredd Blog continues to produce material mentioned in that paper as "gray literature" (a.k.a. grey literature) as a public service (What is Grey Literature?, Gray Literature).

The corporate media on the other hand doesn't cover this issue very much, if at all, which may be a factor in the ongoing negligence or denial by port authorities.

The alt-right wing of the corporate media spends more time denying these issues than the more responsible journalists spend reporting them (While we fixate on coronavirus, Earth is hurtling towards a catastrophe worse than the dinosaur extinction).

II. Today's Post

Today's post is an update using the most recent Permanent Service for Mean Sea Level (PSMSL) dataset, as of April 6 this year (PSMSL Data Page).

The graph data is presented by PSMSL "Coastline code" sequence only (when there are two graphs of the same Coastline Code, one is sea level fall, the other is sea level rise (the sea level fall and rise graphs are from different WOD zones in the same Coastline Code location ... see HTML appendices).

The HTML and graph beginning and ending years and amounts are not in strict syncronization because they are done by two different modules.

I am finishing up on a program that solves that, but remember that the graphs are for showing the trends in a coastal area, while the HTML files are to provide details of a different sort.

The HTML-format data is alphabetized by Country name first and Coastline code second.

The HTML table menu below gives you a one click trip to appendices which have the data laid out for your perusal.

The links are alphabetical (e.g. countries with names beginning with an "A" are in the "A-C" appendices, countries with names beginning with a "U" are in the "U-Z" appendices, etc.):
