The Question Is: How Much Acceleration Is Involved In SLR - 9?

Fig. 1 The acceleration fingerprint

The world's oceans absorbed approximately 150 zettajoules of energy from 1865 to 1997, and then absorbed about another 150 in the next 18 years, according to a study published Monday in the journal Nature Climate Change.

So, today let's continue to ask the critical question considered in this series (The Question Is: How Much Acceleration Is Involved In SLR?, 2, 3, 4, 5, 6, 7, 8).

First, some detail from yesterday's paper:

"So since 1997, Earth's oceans have absorbed man-made heat energy equivalent to a Hiroshima-style bomb being exploded every second for 75 straight years."

"But the study's authors and outside experts say it's not the raw numbers that bother them. It's how fast those numbers are increasing.

"After 2000 in particular the rate of change [acceleration] is really starting to ramp up," Durack said.

This means the amount of energy being trapped in Earth's climate system as a whole is accelerating, the study's lead author Peter Gleckler, a climate scientist at Lawrence Livermore, said."

“Given the importance of the ocean warming signal for understanding our changing climate, it is high time to measure the global ocean systematically from the surface to the ocean floor,” said NOAA oceanographer Gregory Johnson.

(emphasis added; Lawrence Livermore National Laboratory, Industrial-era global ocean heat uptake doubles in recent decades, Study: Man-Made Heat In Oceans Is Surging, Has Doubled Since 1997). This is serious acceleration that makes the above quote "it is high time to measure" a gross understatement.

This answers the question, which some may have had in their mind, as to why the Dredd Blog software model shows acceleration of the danger to the following seaports in the following zones:

The zones listed above contain the top 100 seaports in the world, and the sea level change (SLC) in them, as shown by lots of previous Dredd Blog graphs, is endangering these seaports (The Evolution of Models - 19).

Which in turn endangers international trade civilization (which evolved from industrial civilization).
