The Young Old Sea Level Change Hoax - 4

World's Largest Desert

I. This Series

This series has presented extrapolations from the World Ocean Database Manual (Appendix 11) where that manual presents maximum and minimum temperature and salinity measurement boundaries (The Young Old Sea Level Change Hoax, 2, 3).

The gist of this series is that we can use the values in that manual in an exercise to disprove the hypothesis that "thermal expansion is the major cause of sea level rise" as well as the hypothesis that "thermal expansion is a major cause of sea level rise".

In other words, those hypotheses can be and are falsified.

This is important because we must know the causes of sea level rise if we are to avoid that serious threat (Why Sea Level Rise May Be The Greatest Threat To Civilization - 4).

II. Today's Graphs

In previous posts of this series I indicated that more graphs would be forthcoming in subsequent posts, so here are some additional graphs:

Depth Level
Total Thermal
Expansion &

I have added some perspective to the graphs in the sense that the previous graphs considered one temperature range, which was the median between the maximum and the minimum.

Today there are two additional temperature ranges, 75% of the maximum and 25% of the maximum.

The purpose is to show that at all temperatures thermal expansion is not "the" or even "a" major cause of sea level rise.

Four depth levels are featured, which are not the same four depths shown in previous posts in this series (In a previous post I wrote that I would use different depths in upcoming posts). 

III. The "ttsSLC" Graphs

This section of graphs show the total thermosteric sea level change from 1900 to 2020 (a 120 year span of time).

Three different ocean temperature perspectives are graphed (25% of maximum, 50% of maximum, and 75% of maximum.

By "maximum" I mean the maximum ocean temperature for a particular ocean as informed by the historical GISSTEMP temperature anomaly record. 

Since about 93% of global warming increase ends up in the oceans of the world, and the GISSTEMP records are useful for historical temperature perspectives, I fuse the two together the do the thermal expansion/contraction calulations.

The result is a three-line graph that shows the result over time in millimeters of sea level change.

IV. The "hO" Graphs

The "hO" (a.k.a. "potential enthalpy", a.k.a. "ocean heat content") graphs show the heat energy in seawater at various depths.

They represent the amount in joules per kilogram (J/kg x 104) in of seawater at the relevant depths and temperatures.

V. The "CT" Graphs

The "CT" (a.k.a. "Conservative Temperature") graphs show the relevant seawater temperatures at which the ocean heat content (hO) develops.

VI. The "tsSLC" Graphs

The "tsSLC" graphs detail the thermal expansion and contraction induced sea level change (changes in volume per fixed mass unit) at specific individual depths which the maximum minimum temperature values apply to.

VII. Closing Comments

This may be the last post in this series because it has a limited purpose, which is to try to get us all to focus on the melting glacier ice at tidewater locations in Antarctica.

If researchers can't figure it out at this point, they may never do so.

The other related series here on Dredd Blog will continue to deal with in situ melting induced by in situ measurement conditions.

The next post in this series is here, the previous post in this series is here.
