XKCD: Timeline of Global Temperatures, with projections

I need a new blog to keep track of Environmental Issues. This "cartoon" presents a succinct overview of Global Temperature for the last 20,000+ years. https://imgs.xkcd.com/comics/earth_temperature_timeline_2x.png

Most rudimentary drift voyaging. With notes about drifting, and drift logs.

Neyret, in his Pirogues Oceanennes(1) opens his first volume ,on Australia and Melanesia, with this, as his first, most fundamental type of boat: a Tasmanian flotteur simple:



"Single (or simple) Float: It is a simple roughly trimmed shrub trunk, the big end at the front and the back finished in point, on which the swimmer rides. Thanks to the swollen shape at the front and tapered at the back, the aborigines claim that the crocodiles believe they see one of their kind swimming flush with the water, and do not come to attack him... If this is true, this mode of transport is not recommended near the mouth of the rivers, because, claim other natives (Salomonnais) sharks are very attracted to the crocodile and willingly come to snatch a steak or two. This float is in use along the north and northeast coasts of Australia.This is presented as an implement used by Aboriginal Australians as a river craft." (Translated from the French via Google Translate.)

This is an epiphany for me, connecting stories I was privy to, decades ago about the ancestor of a student of mine.  This student, whose exact name has unfortunately slipped my mine,  has a Gilbertese name (Chuukese have adopted surnames, a practice encouraged, at least in part, by the Roman Catholic church, who made it a requirement on baptism).  His ancestor is said by my son's people to have drifted---in the water---from Kiribati to Nama.  One would assume he had held onto some floating object, but I don't know whether this is the case; he was said to have been washing in the waves at the time of his discovery.   Such drifts are known to have taken place(2).  

This man, Akurupw, was said to have been festooned by barnacles and algae growing on his skin and nails when he washed ashore.  He was discovered by a local woman who was performing her morning ablutions at the beach on the windward side of the island, which is less than 1 mile long.  According to the story, the woman who discovered him married him.  Akurupw, according to islanders alive today, taught Nama islanders shark magic.  Arthur Grimble, a former district administrator of the Gilbert and Ellice Islanders at about the time of World War I, described, in A Pattern of Islands(3). a methods used to kill at least one of the most feared sharks, mako and tiger sharks, by swimmers.  This story rings of truth.

A simple float of this kind, compels the imagination, potentially filling in some blanks in the story of inter-island movements during low sea level stands, when distances between islands of the W. Pacific / Indian Ocean sphere were greatly diminished.  Such a stylized float is unknown in Kiribati, to my knowledge;  however I once was privileged to accompany a fishermen of remarkable skill at Aranuka Atoll, whose skill I have never seen surpassed who used a piece of gnarled driftwood, of roughly the dimensions of a four by four inch board, something over a meter long.  Cracks on the board served as stashes for fish hooks.  Two small sticks fastened across the board served to wind a significant length of monofilament fishing line, sufficient to reach the bottom at a depth of 20 feet or more.  A spear, made from a piece of thick iron wire was stuck into a long crack in the board, in case it was needed, with a "sling," a loop made up of inner tube from possibly a tractor tire with a length of thick monofilament into which to notch the spear.  This was towed by him across the reef platform, tied to his waist by at least 15' of home-made sennet.  A shorter length of sennet, or perhaps piece of salvaged wire, was attached along the length of the board, serving as a stringer for the many fish that he caught---some with the spear; others with the fishing line as he swam on the surface and dangled the hook in front of his quarry---in one case a grouper some 18" long.  I do not recall, but he may have been using home-made goggles carved from wood with pieces of glass from the wreck of a WWII airplane.  All in less than an hour, he caught enough fish for a large extended family gathering.  

 This fishing tale is off topic, but it illustrates how a piece of wood, even simpler in some respects---yet quite sophisticated in others---than the Tasmanian floater, can be utilized by atoll dwellers, who are absolutely tied to the sea.  In the case of Akurupw, such a float, or perhaps parts of a swamped or broken up canoe, might have served as flotation during a long drift, during which, we might imagine, he may have been able to grab a few fish or jellyfish---I have seen jellyfish cleaned and eaten on Kuria Island.

The next few items in Neyret's volume are rafts, and throughout the book, as it presents canoes from various locations in Melanesia, rafts of varying degrees of sophistication.  This simplest are just two logs lashed together.

Along as similar vein, as has been explained to me, fishermen from Nama Island are forbidden to fish on a drifting log.  Life on a 1 mile-long coral island is intimately tied to the sea; survival depends on skill in a huge variety of fishing methods.  Blue water fishermen in the west, on overpowered, oversized boats know that fish congregate around and under drifting logs.  Fish have no eyelids or irises, so  the shade under a drifting log may be be a previous resource for them.  On Nama they an extremely precious resource, so much so that it is a regulated one.  All Nama islanders belong to one of three clans.  Each clan holds proprietorship over one of three types of drift logs.  When a log is spotted, note is taken of which type, and, according to traditional practice, back on shore the chief of the clan, appropriate to the type of drift log, is notified of the spotting of a drift log.  The clan then goes into action.

Each clan has a special fish strap for its specific drift log.  I do not recall the categories of drifting logs, but I remember that one of them is cut logs that have fallen off of ships; one imagines these are also valued for lumber for canoe building.  Another is a whole tree, roots and all, with soil still attached.  It seems logical, without knowing such details, that the soil might also be prized.  I do not remember the third type of log.  

The clan members bring the trap, now, out of mothballs, so to speak.  These are said to be oversize traps, needing to be strapped onto the canoe (or canoes?).  After being transported out to the trap, an apparently highly ritualized process is involved the fishing; some living persons may know aspects of this process, and logs may even be fished today in accordance to these restrictions; however, most such fishing methods have lost at least part of the details involved, including perhaps magical incantations or formulae.  Expertise on the islands is tightly held, and these methods are probably steeped in secrecy.  Attachment of the trap to the log is such a ritualized process.  A certain member of the party is expert in swimming under the log with the rope (hand made, no doubt), with knowledge of chants and preparations.  This person, after appropriate ritualized preparations, jumps into the water, and swims under the log, chanting to himself a protective chant or prayer, for protection from the sharks that are probably nearby.

I do not know further details about this process, which was explained to me by Akitaro, the uncle of my son.  

I am interested in the calendar of natural signs (esissin) that predicts, among other things, aggregations of fishes at certain passes in atolls---for annual spawning aggregations.  For example, Eryrthina cf. variegata (paar) flowering is a signal for pelagic fishing across the Pacific.  On New Caledonia and Hawaii (for another species of Erythrina) both, it is a sign for shark hunting; elsewhere in Polynesia, for whaling season.  A man from Lamotrek Atoll,   asked "Do you know the tree that has a star?"  It was Erythrina sp.  The star is Pleiades, and they are associated, according to this man, with the time of drift logs.

Voting: the worst form of government except for all the rest

 When I first arrived in Micronesia, in Majuro in 1979, a project was in full motion to educate the public in the Marshall Islands about the choices they would soon face at the ballot box: Vote Aet (yes), or Vote Jab (no), on the issue of whether to join the United States in a "Compact of Free Association", or perhaps whether to join other island entities---Palau, Truk, Pohnpei, Kosrae---in a federation.  At this point, it doesn't matter which. 

The does matter, in my opinion, is how the elections---taking place across all of Micronesia---were being packaged and conducted.  What truly matters is whether the voters understood their choices.  In my opinion, despite an ongoing blitz of information at the time, and, I think, a high interest among voters, the choices were a masquerade concealing a plethora of aspects---the undiscussed (or under discussed) aspects of the bill of goods that was being sold to them. 

The educational blitz was mandated by the United Nations to ensure the voting public in the islands would be awakened to the options, as they achieved self-determination.  But it was an impossible conundrum: they could not possibly understand what has been sold them.


The same went on elsewhere.  Slogans, posters, signs, speeches, radio blitzes---radio what the only significant medium at the time---could not possibly explain what was to come.  It was, in other words, a sham.

We hold that the entire idea of democracy is wonderful;  we assume others, from other cultures, will automatically understand.     Democracy depends upon the full knowledge of the governed.  Thus, the mandate to educate the populace of these islands is critical to success; but success of what?   This election was another rotation of the drums of a steamroller, and the project to enlighten the public about the stakes at hand seemed, to my mind, a failed one.  

Just like elections in the United States, this election involved unspecified issues, and undisclosed and unpredictable consequences.  What is an election anyway?  How does this fit in with everything I have ever known?  It's fun to vote, but what does it all mean?  


============ How it is done

Than again, an election might be constructed and executed in a manner consistent with culturally historical realities.  

I was told the story of the assistant major of an island, who was a resident of a certain village, in another Micronesian entity.  This assistant mayor was a well respected man around the village,   a deacon or assistant pastor of the village church, as well as a government official in the department of education.  He made sure to be the first person to vote in an election at some point, I never knew what the election was about.  He marked his ballot openly, before the witnesses around the polling place, and openly showed how he had marked the ballot.  The voters were given the option to "open vote," or to sit before the assistant major, and mark her ballot before him; or to cast a secret ballot, marked privately in a voting booth.  

During those times, the government of the islands made available a fiberglas fishing skiff and outboard motor to each family.  I seldom if ever saw one of these fishing project skiffs used for fishing; usually they were used as transportation into town.  The fishing project was a failure, but the standard of living, I suppose, was "improved."  

As the story of the assistant mayor's influence over the vote happened, I was told that no-one who did not Although most families received fiberglass boats from the fishing project, I have been told that no-one who did not Open Vote ever did.  Boats were distributed by the Mayor's office, which also redirected road building funds for construction of a road from the dock to the Mayor's residence; this was the only road on the island at the time.  It might be argued that this greedy behavior helped to conserve the island's natural environments.

Climate requires more attention.

 Eliot Jacobson's Climate Work

 Eliot Jacobson's Climate Blog is a worthwhile stop on the Internet Superhighway.  Prof. Jacobson first came to my notice when I stumbled upon his discussion of the debris flows in Montecito, in my home town of Santa Barbara.   As it turns out, Dr. Jacobson was formerly a professor of Mathematics and Computer Science at UCSB, my alma mater.  That was cool; but the main attraction was his graphs, representations of climate data.  As a science educator, and for personal studies of tides, I have focused a great deal of attention on graphing.  To emphasize the usefulness of graphs, I gave students pages of numbers that were at least perplexing and not easy to understand as numbers on a page alone.  Graphs bring life to these pages of numbers, and sense.  Jacobson is great at it.  

 His web page at  https://climatecasino.net/, and a more recent compendium, I Jump, are worth visiting.   

Early Bellweather of the Effect of CO2

 Fossil fuel and profit extraction corporations knew relatively early of the effects of the burning of Fossil Fuels.  Incredibly, those corporations and greedy barons continue to conceal or obfuscate the truth about Carbon Dioxide and other Greenhouse Gas emissions, taking advantage of the Supreme Court's decision that Corporations are persons, and can therefore contribute an unlimited amount to political campaigns.  I was troubled to learn of work by scientists in the employ of fossil fuel centered corporations such as Exxon and Shell, and automobile manufacturers in the late 50s, showing the dire consequences of continued use of such fuels and automobiles driven by internal combustion engines, and that these corporations continued---and to a great extent continue to this day---to build a dynasty, on a foundation of deception of the public, and denial.

Even more remarkable is this document, linked below, written by the chemist Svante Arrhenius, in 1896. This pdf is prefaced by the following description:

Arrhenius’s paper is the first to quantify the contribution of carbon
dioxide to the greenhouse effect (Sections I-IV) and to speculate about
whether variations in the atmospheric concentration of carbon dioxide
have contributed to long-term variations in climate (Section V).
Throughout this paper, Arrhenius refers to carbon dioxide as “carbonic
acid” in accordance with the convention at the time he was writing.

A visual history of pandemics from The Bulletin of the Atomic Scientists

In 1996, I scored, bigtime; an improbable life-changing event. I had been staying at the home of a family in Merizo for many months. In order to introduce them to my family, who had flown in from Chuuk, we stopped our rent-a-car at my friends' home, intending a short stop, just for a few minutes. 

 Their phone (alandline) rang; strangely, it was a call for me! I never received calls on their line. On the other end, a voice asked, would I accept a job on Saipan teaching Health Science? The salary would be sufficient for subsistence, and housing would be provided. Could we be at the Guam airport early the next morning, myself and family? 

I could---and probably should---elaborate, contextualize this event. But to cut to the chase, we were at the airport the following morning, and that evening we were comfortable in a temporary lodging provided for us in a local hotel. Things did not go smoothly, but thanks to a wonderful team from the CNMI Public School System we soon had an apartment and I, a job at Marianas High School. 

My Health Education job turned into Biology and Environmental Science. Perfect! From the star, teaching in Micronesia involved a heavy dose of Environmental Science. In Chuuk there was a book, but abundant opportunities for focusing on local problems and issues, students were engaged in confronting numerous local issues, often involving the collision course between their tranditional ways and the new economy of money, politics, plastics, frozen food, canned food, monofilament fishing line and nets, the exhustion of fish stocks, encroachment of fishing fleets from around the world, new ideas about consumption... I could go on. 

The experience of students on Saipan was a step ahead of those in the other Micronesian entities. The U. N. Trust Territory of the Pacific Islands maintained headquarters on Saipan, reigning over all of those other diverse entities--The Marshall Islands, Kosrae, Pohnpei, Chuuk, Yap, and Palau. The locals on Saipan organized and learned to tap into the massive federal resources. They learned the game of political control, and when the time came for "self-determination" (as mandated by the U. N.), they had a leg up, and already were in the driver's seat. 

Development---all of those new or improved trappings referred to in the previous paragraph---was already on track for bigger and better things.  This story will probably be told elsewhere, but in all likelihood, the first draft has already been written by those educated by their captors.  

My job was not the same on Saipan, then, as it had been in Chuuk. Students from diverse backgrounds and languages had different perspectives, so I was at a disadvantage. The books, surprizingly, since the budget of CNMI PSS was an order of magnitude larger---thanks to the influence of the local population in Territorial political affairs---than the Chuuk State Department of Education.  And the Chuuk DOE had 100 schools to deal with! But the books were better in Chuuk. Go figure. 

 I now had an Internet connection and PC, at home, and devoted a considerable amount of time and energy to developing classroom materials. The new (to me) search engine, Google., made swift work of searching; buton a typical day, I wouild be lucky to find ONE (1) article about any important environmental issue of consequence for the islands. I tell this story to illustrate how much things have changed over the past 25 years, for that is how long it has been. What I really want to show show is a web page I just encountered today, in 2023, of monumental significance to Environmental Science: an article, a visual history of pandemics.
