On Thermal Expansion & Thermal Contraction - 17

Fig. 1 Zones & Layers
I. Background

This is a follow-up to yesterday's post (Databases Galore - 19) which detailed all the relevant layers, zones, and stations on the planet we are living on (You Are Here).

Fig. 2 Layer Zero
I say "follow-up" because I could not reasonably place today's information in that post, seeing as how it was so very, very long (it is now a reference library, as it were).

The thing about it is that you can look up any layer, zone, or station that grabs your interest in today's post by going to yesterday's post and finding that layer, zone, or station.

II. Today's Graphs

Today, we revisit the hypothesis of steric sea level rise, a.k.a. thermal expansion.

Fig. 4 Layer Two
As a visual aid I have placed salinity, temperature, and sea level change averages for each Layer featured in yesterday's post.

Fig. 5 Layer Three
The temperature and salinity lines on today's graphs (Fig. 2 - Fig. 18) consist of the average of all measurements at all depths in each particular Layer graphed.

Fig. 6 Layer Four
The sea level lines on today's graphs consist of the average of all tide gauge station records in that Layer.

Fig. 7 Layer Five
III. Today's Purpose

These graphs show the radical difference between the salinity and temperature lines compared to the sea level lines.

Fig. 8 Layer Six
The argument being made is that the temperature and salinity do not generate the sea level changes.

IV. How To Peruse
Today's Graphs

The scale at the left of each graph is "millimeters, degrees C, & units."

Fig. 10 Layer Eight
The "millimeter" values apply to sea level change.

The "degrees C" values apply to ocean water temperatures.

The "units" values apply to the salinity ranges.

Fig. 11 Layer Nine
Ocean temperatures globally range from around -2 C up to around 35 C; salinity ranges from about .5 up to about 40.

Fig. 12 Layer Ten
But when only a layer and the entire ocean depth at that layer are considered, the range becomes narrower.

Fig. 13 Layer Eleven
Salinity tends to be in the 20's and 30's, ocean water temperature ranges between about 12 degrees C down to about minus 1 degree C.

Fig. 14 Layer Twelve
Measurement averages, limited to a latitude layer, are even narrower.

Fig. 15 Layer Thirteen
Sea level changes from the same layer and zone, however, cover ranges from about a hundred millimeters of fall to a couple hundred millimeters of rise, because for one thing, in that case we are talking only about the surface of the ocean.

Fig. 16 Layer Fourteen
The general take home is that the radical gyrations of the sea level lines are not in sync with salinity and temperature lines as they should be in a "thermal expansion is the major cause of sea level rise in the 19th and 20th centuries" world.

Fig. 17 Layer Fifteen
If thermal and/or salinity values were the major factor in sea level rise or fall, that should show up on these graphs as synchronized lines.

Fig. 18 Layer Sixteen
In other words there should be some visible synchronization of ups and downs in all of the graph lines.

That is not the case, so I will continue to argue:
glacial and ice-sheet melt and disintegration is the major cause of sea level change.
I will argue that until someone can validate the veracity of the notion and assertion that "thermal expansion is the major cause of sea level rise in the 19th and 20th centuries."

Until that validation happens, that hypothesis has been falsified IMO.

V. Is This Comparison Fair?

Is the comparison of sea level records with salinity and temperature records fair?

Or is it comparing apples to oranges?

Is it ok to compare issues of temperature and salinity which only attain 40 on the scale to sea level that goes much higher?

How can millimeters and degrees be compared fairly?

The answer is that it depends on the purpose of the comparison.

Like I said, there should be a visually discernible pattern of some sort.

It should be a pattern that clearly links temperature to sea level.

If in fact they are linked in a major way as the thermal expansion hypothesis alleges, it should be visible in the graph lines.

I think that is a fair assertion.

VI. When Should
The Syncronization
Be Visible?

Since the hypothesis holds that any thermal expansion is a result of temperature increase, it should appear immediately or very soon after the temperature of the ocean water increases.

The relatively flat lines of temperature and salinity compared to the ups and downs of sea level shown in these graphs is absent any such indication.

The temperature ranges are very narrow.

The salinity ranges are very narrow.

The sea level ranges are not so narrow.

This indicates to me a lack of nexus, a lack of causation.

Simply put, thermal expansion is not the major cause of the sea level changes shown in these graphs.

And they are graphs of all of the world's oceans over a span of many years.

Collected in many cases way before the science came under attack by the fossil fuel industry.

Way before their murder suicide madness engendered the mass attack now taking place in the public eye.

VII. Conclusion

The video at the end of today's post indicates that the scientific community has been under attack for many years, for decade after decade.

Can we guarantee to ourselves that the fossil fuel industry did not succeed in the slightest when they spent billions of dollars destroying the minds of the public about climate change they were initiating?

Any assertion that "science was in no way impacted" is especially hard to accept as true when we see what has taken place in the U.S. government.

One long lasting dogma fostered by big oil's corruption of science research managers, who need funding all the time, was the "Antarctica 1.0 dogma" (a dogma that its surface was not melting, that it was stable).

Now that we have the truth of the scientific matter (Antarctica 2.0), indicating a long term cover-up, as with other issues (Smoke & Fumes), we must no longer trust without verification.

Which includes the "thermal expansion is the major cause of sea level rise in the 19th and 20th centuries" hypothesis.
