The&nbsp;<em>coastal areas<\/em>&nbsp;are generally neutral and pale blue-ish, indicating either no movement or slightly subsiding.&nbsp; But, it is important to look at the scales.&nbsp; There are two scales given. The top scale if for large scale subsidence \u2013 darker blues through greens to lighter colors.&nbsp; This scale is for &nbsp;+\/- 100 to 200 (or greater) mm\/year.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lower scale is in&nbsp;<em>single digit<\/em>&nbsp;mm\/year, +\/- 4.&nbsp; &nbsp;&nbsp;This lower scale of subsidence, 0 down to -4 mm\/yr, is equivalent in magnitude to the rise in&nbsp;<a href=\"https:\/\/earth.gov\/sealevel\/faq\/123\/what-is-the-difference-between-absolute-sea-level-change-and-relative-sea-level-change\/#:~:text=Absolute%20sea%20level%20change%20refers,absolute%20sea%20level%20is%20rising.\" target=\"_blank\" rel=\"noreferrer noopener\"><em>absolute sea level<\/em><\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And that is the important point.\u00a0\u00a0 The coastal portion of the state of California is generally subsiding at a rate of 1 to 4 millimeters per year.\u00a0 At the same time, it is generally understood that absolute sea level, often called \u201cglobal sea level\u201d, is rising at about 2 to 3 mm\/yr [when using global tide gauges for the calculation].\u00a0\u00a0 In effect then, Relative Sea Level Rise along much of the coast of California can be said to be \u2018doubled\u2019 by subsidence.\u00a0\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To be blunt, the Realtive (or Absolute) Sea Level Rise of 2 to 3 mm\/yr is not an alarming or dangerous amount. In a century, 100 years, 3 mm\/yr comes to 30 cm or 1 foot.&nbsp; Most areas have already seen that 1 foot of SLR over the previous century without disastrous effects.&nbsp; To counter-act that 1 foot , those 30 cms, of sea surface rise, a sea wall or dock curbing&nbsp; 16 inches (440 mm) high, made of two standard 8x8x16 inch concrete blocks (in the EU, 215mm x 215mmx440mm) suffices.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And if we&nbsp;<em>double that amount<\/em>&nbsp;of Relative Sea Level Rise, say to 6 mm\/yr, half of that being subsidence, the total rise comes to 24 inches, 2 feet or 60 cm.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now, 2 feet, that\u2019s getting to be something to talk about for locales that have infrastructure built far too close to current sea level or too close to&nbsp;<em>the sea level&nbsp;<\/em>of&nbsp;<em>the past<\/em>, which is far more common.&nbsp; &nbsp;And for locales that have very little altitude above sea level altogether, such as low-lying lands, filled salt marshes turned into sea-level-plus-1-foot neighborhoods of houses with backyard docks on canals and other high-risk areas.&nbsp; Those low-lying&nbsp; areas are often spoken of as being \u201cat risk from flooding by sea level rise and storm surge\u201d.&nbsp; And they are, and they already were, even a century ago.&nbsp; They are more at risk today and will be even more at risk after another 100 years.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reason they are at risk is their relative altitude above sea level.&nbsp; One foot, two feet, five feet, six feet \u2013 the same in meters \u2013 it doesn\u2019t matter.&nbsp; Storm surge can be as high as 14 feet \u2013 over 4 meters.&nbsp;&nbsp; The surface of the sea will reliably rise about one foot \u2013 30 cm \u2013 over the next century and to that&nbsp;<em>must be added<\/em>&nbsp;any local subsidence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But what they are not&nbsp;<em>at risk from<\/em>&nbsp;is&nbsp;<em>Climate Change<\/em>.&nbsp; The best long-term studies of relative sea levels around the world show that sea level has had a long steady and slow rise since man has been actively measuring it.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The claims that melting land ice is a major contributor have not been shown to be true.&nbsp; &nbsp;Water from melting land adds to the absolute sea level rise that is caused by expansion of the sea water due to the gentle warming of the oceans as the world continues to come up and out of the Little Ice Age.&nbsp; &nbsp;By current rather vague calculations, melting land ice \u2014 glaciers, Greenland, Antarctica \u2013&nbsp;<em>may be<\/em>&nbsp;adding up to 1 mm a year \u2013&nbsp; few inches, 10 centimeters per century.&nbsp; &nbsp;&nbsp;The uncertainty stems from the absolute uncertainty of Antarctic ice mass:&nbsp;&nbsp; is it growing or declining, adding mass or losing mass?&nbsp; Even NASA, which measures Antarctic Ice Mass is not sure, it has&nbsp;<a href=\"https:\/\/wattsupwiththat.com\/2021\/10\/06\/antarctic-ice-mass-alternate-sources\/\" target=\"_blank\" rel=\"noreferrer noopener\">two teams that find totally different answers<\/a>, both answers derived from the same data sets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To fight&nbsp;<em>Climate Change<\/em>&nbsp;the IPCC and the UN (and everyone else on the bandwagon) say we must decarbonize our societies, we must quit adding CO<sub>2<\/sub>&nbsp;&nbsp; to the atmosphere regardless of cost.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Combating&nbsp;<em>Climate Change<\/em>&nbsp;may or may not be a good idea \u2013 I don\u2019t think it is \u2013 but one thing it&nbsp;<em>will not do<\/em>&nbsp;is slow or stop sea level rise, not even the fraction of sea level rise actually caused by warming seas.&nbsp; Reducing CO<sub>2&nbsp;<\/sub>emissions, atmospheric concentrations of GHGs&nbsp; or sequestering CO<sub>2&nbsp;<\/sub>underground or in rocks certainly cannot change the portion of relative sea level rise caused by subsidence.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Spending tax payer\u2019s money, or society\u2019s wealth, to fight&nbsp;<em>Climate Change<\/em>&nbsp;will do nothing to prevent today\u2019s or tomorrow\u2019s problems stemming from rising seas.&nbsp;&nbsp; Those funds must be spent on adaption to and mitigation of any negative effects of rising seas.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wild and alarming \u201cpredictions\u201d of meters of&nbsp;<em>Climate Change-<\/em>driven sea level rise \u201cby 2025\u201d \u2013 in the next 30 years \u2013&nbsp; are scientifically ludicrous as such a future is literally impossible.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is however possible to drive very local Relative Sea Level changes by seemingly impossible amounts through human activities such as &nbsp;extracting water, pumping water out of aquifers below the surface, &nbsp;or pumping up &nbsp;huge volumes of oil, can cause substantial subsidence and conversely, forcing volumes of water or gases (such as in fracking)&nbsp; down into the Earth under pressure (causing uplift).&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Bottom Lines:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1.&nbsp; The seas and oceans are rising, have been rising and will continue to rise until the planet again enters a period of cooling, similar to the Little Ice Age or a real full-blown ice age.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2.&nbsp;&nbsp; Current rates of sea level rise will not be changing much.&nbsp; If a locality is not currently at risk, it will not be at risk in the future \u2013 sea level rise is too slow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3.&nbsp; Human infrastructure already at risk will continue to be at risk and that risk will increase in the future \u2013 slowly and steadily.&nbsp; Such localities should spend money and effort on adaption and mitigation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4.&nbsp; Vertical Land Motion \u2013 up and down \u2013 are important factors for localities to consider when looking at risks from relative sea level rise.&nbsp; Nothing in the fight against<em>&nbsp;Climate Change<\/em>&nbsp;will effect VLM. Some of the VLM can be mitigated; such as ceasing to extract fresh water or oil close to the sea.&nbsp; Some of the VLM-caused Relative Sea Level Rise must be dealt with by adaptation \u2013 raising structures, building seawalls and otherwise protecting infrastructure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">5.&nbsp; Alarming projections of dangerously high near-future sea level rise are not possible, thus the dissemination of those projections must be seen as politically-motivated Climate Alarm propaganda.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong># # # # #<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Author\u2019s Comment:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is nothing particularly new in this essay, except for the very interesting study on California VLM \u2013 look at the Central Valley.&nbsp;
