toxic big island school grounds

Sea level in Hilo might rise a foot or two in 20 years. Three to six feet by the year 2100. Most of Hilo will be above water..

As HOTPE points out Hilo's topography is sloped so as to be better situated than Honolulu, but even there the ground has enough topography to mitigate larger impacts like those anticipated in some places on the mainland. There is a great tool to help visualize Hawaii's sea level rise here:

https://www.pacioos.hawaii.edu/shoreline/slr-hawaii/

Which uses the global sea level rise projections from the 5th Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), the United Nations body of leading climate scientists and governmental representatives. Their website is here:

https://www.ipcc.ch

They project something just shy of 1 foot by 2040, and just over 3 feet by 2100.

For a more expansive view, both here and across the globe, and allowing for a much larger projection in rise..

https://coast.noaa.gov/slr/

Is a pretty cool tool..

Thanks for all of the various input on this morphing topic. I find it all very interesting. Many knowledgeable people here. If I could I would click a "like" button on lots of these posts. ~Hope you day is filled with aloha.

MarkD - I'd hate to see the plight of our poor performing students in East Hawaii--and poor performing adults--be blamed on chemical exposure ... Too much time getting high. Smoking ice and excessive amounts of marijuana

Cognitive dissonance much? Documented exposure to lead and other neurotoxins has got nothing to do with it, but THC is the key (chemical) culprit? Just add them in to the innumerable novel chemicals we are exposed to every day (far more than 1600s Londoners could even dream of).

The Rome analogy seems apropos though - emperors hand down edicts and fiddle while the commoners watch their homes burn... You're probably onto something there!

ETA: The Atlantic quote (as next to nobody actually reads the links)
"The law we do have is the Toxic Substances Control Act (TSCA, pronounced toss-ka among those in the know). Passed in 1976 under President Gerald Ford, it is still today the primary U.S. law regulating chemicals used in everyday products. [...] It only requires testing for a small percentage of chemicals, those deemed an “unreasonable risk.”
[...]
Landrigan also calls it “a particularly egregious lapse” that when TSCA was enacted, the 62,000 chemicals already on the market were grandfathered in, such that no toxicity testing was required of them. These chemicals were, as Landrigan puts it, “simply presumed safe” and allowed to remain in commerce until a substantial health concern came to public attention.
[...]
In the nearly 40 years since the law’s passage, more than 20,000 new chemicals have entered the market. “Only five have been removed,” Landrigan says."

That's baseline sea level. Consider the storm surges that already flood Bayfront.

Agreed, we should stop using electricity until it can be proven to be safe. Safety first.

Yep, any idiot can spew bulls*t like that Paul. Why don't you try for something a little more intelligent? Oh I am sorry, that was your best shot already.

Never mind.

Oh, sorry, I thought electricity caused electromagnetic radiation. Thanks for setting me straight.

Aminopyralid, the herbicide in Milestone, does not have nearly as long of a half life as chlordane, but it can linger for over a year. It’s been used more and more heavily to control albizia across the windward side. I’d be wary of using mulch from treated albizia. I’ve seen Milestone described as safe as a bit of spilled motor oil on Punaweb.

“Under aerobic conditions, degradation of aminopyralid in five different soils resulted in the production of CO2 and non-extractable residues. Half-lives ranged from 31.5 to 533.2 days in 5 soils. For risk assessment purposes, EPA used a half-life of 103.5 days.”

I have a good friend who has been in the tree trimming business for 20+ years.

He told me of a poor individual he knew that did a lot of freelance trimming work but wasn't careful enough with that chemical stuff they use on the stumps.

He had to quit working to support his family and collect disability because of terrible nervous system problems due to overexposure to the herbicide. He'll never be the same.

Poor guy.

Nasty chemicals there.

rainyjim - I found some information on early uses of arsenic as a weed killer if anyone is interested - https://ucanr.edu/repository/fileaccess.cfm?article=163744&p=GZBXGG

I still suspect the arsenic used in Hawaii’s sugarcane fields was for rat poison, not weed killer.


You seem to be not reading the links already provided. Arsenic herbicides were used as primarily alongside buildings, where the highest soil concentrations were recently found. As you noted, you obviously don't indiscriminately spray a broad herbicide across your crops (unless you want the field to be barren - for up to 4 years apparently, from your link).

Other goodies and folkisms include:
- "the inorganic forms of arsenic--the sodium, calcium, and lead salts of arsenic as well. as arsenic trioxide- -are very poisonous agents. The annual review of news articles by the press reporting accidental poisoning, usually of children and often pets and livestock, attest to the hazards associated with the indiscriminate use of arsenicals by the lay public."

For EW - "Wisely employed, these weed destroying chemicals can beautify the home while taking the drudgery out of the means to this end. But, for the uninitiated home owner, beware of indiscriminate use. [...] The adage -- "If a little bit is good, more is better" -- may work with paint bucket and brush on the side of the house, but can be ruinous in both the back 40 and the back yard where herbicides are concerned."

Ahh, the good old days - lead in the paint, arsenic in the lawn - who needs nostalgia when you have long-term human and environmental damage to remind you!

Yes!
And don’t forget the mercury in our fillings, and lead in our easy-to-roll toothpaste tubes. Incredible we didn’t drop right over dead before we reached 40. I did have a few near misses playing Lawn Jarts in my parents chemically infused back yard though. Which we immediately abandoned, Jart in midair, whenever the DDT fogging truck came through the neighborhood. We’d jump on our bikes and follow it down the street, close behind, huffing and puffing trying to keep up, for a good 4 or 5 blocks.
