Yesterday's post was about the doubling of heat content in the oceans.
It took 132 years to double the last time and this time it doubled in only 18 years.
Today's post comes on the day that NOAA officially released its State of the Climate report, which was not expected to be a surprise, rather, it was expected to be a report that would indicate the year 2015 was a record year for global warming.
That is exactly what they reported:
"2015 is Earth's warmest year by widest margin on record;(NOAA, emphasis added). Another report indicated that by 2050 the oceans would have more plastic in them than fish (World Economic Forum).
December 2015 temperature record warm
The globally averaged temperature over land and ocean surfaces for 2015 was the highest among all years since record keeping began in 1880. During the final month, the December combined global land and ocean average surface temperature was the highest on record for any month in the 136-year record."
II. The International Sea-trade-Civilization's Seaports
Of all the ancient civilizations, perhaps ours is more like the Phoenicians than some of the others:
The Phoenicians were a great maritime people, known for their mighty ships ... The island city of Tyre and the city of Sidon were the most powerful states in Phoenicia ... Phoenicia thrived as a maritime trader and manufacturing center from c.1500-332 BCE and was highly regarded for their skill in ship-building, glass-making, the production of dyes, and an impressive level of skill in the manufacture of luxury and common goods.(Phoenicia, cf. Carthage). The current version of "International Trade Civilization" is truly global, not regional like Phoenicia was:
Liner shipping could lay claim to being the world's first truly global industry. Likewise it could claim to be the industry which, more than any other makes it possible for a truly global economy to work. It connects countries, markets, businesses and people, allowing them to buy and sell goods on a scale not previously possible.(World Shipping, emphasis added; cf. Global Container Fleet, Shipping Ports). As go the shipping ports, so goes "International Trade Civilization" (Confusing "Civilization" With "Species").
I am not saying that the human, or any other species, is not threatened, they certainly are, I am saying that in the sequence of events current civilization goes first.
III. Sea Level Change (SLC) Is An Unassailable Threat
It ought not be a mystery why this is so (Why Sea Level Rise May Be The Greatest Threat To Civilization, 2, 3, 4, 5; Weekend Rebel Science Excursion - 44).
|Fig. 2 The Sea has always risen along with CO2|
It is difficult to fathom why there is not more discussion about this predicament and danger to the international trade connecting, defining, and holding together current civilization.
There is a link in a comment made yesterday by Mark Hanson that brings it up:
If the West Antarctic Ice Sheet collapses, sea level would rise by about 11 feet(Climate Change, emphasis added). The danger is operational, and well under way, but it is not fully discussed as it should be.
on average across the earth. “There’s no question at all that the number of people and the amount of stuff that we have close to sea level is huge,” glaciologist Richard Alley said. “What happens to the beach, what happens to our shipping, what happens to our naval base?”
Fig. 3 A civilization way out of tune
As Fig. 2 shows, sea level today is "behind schedule," because in previous instances it went up along with CO2 in every case.
Note that: 1) the historical mark where it ought to be is way above what it is now, 2) the oceans are heating with a doubling acceleration, and 3) global warming is going stronger than ever before.
It seems like we should keep our eyes on what SLC can do (compare Fig. 2 with Fig. 3).
And be mindful that it can happen much more quickly than we are contemplating ("a rise of 10 feet by 2050" - Hansen 2015).
