The authors are seven homeschooled children who were aged 11 to 14 at the time the work was done in the 2012-2013 school year. They did the work as part of a writing and newspaper class taught by Susan Kilbride.
Their assignment was to write three or more articles on Hawaiian culture, on topics “that had a hands-on element in them,” Kilbride wrote.
Much of the work was not from book research, but from talking to people still carrying out the ancient crafts of the Islands.
“My students and I have spent the last year going to every Hawai`ian festival that we could find, meeting with people on field trips, taking classes, and doing everything we could to learn more about the Hawaiian culture,” Kilbride wrote.
The result is a book on making kukui nut oil, crafting bamboo and gourd instruments, tying Hawaiian fishhooks, lei making, stringing Niihau shell jewelry, featherwork, weaving, kapa making and more.
It is written in straightforward language, with ample black and white photography to explains steps in making projects.
The authors are Charlee Brown, Pearl Dickson, Dylan Kilbride, Hope Mashburn, Emily Risley, Molly Russell and Teah Van Bergen. Kilbride is the editor.
There are lots of books on Hawaiian crafts, led by Arts and Crafts of Hawaii, the multi-volume set of scholarly pamphlets published by Bishop Museum Press and written by Te Rangi Hiroa. And there are whole books on many of the individual topics in The Hawai`iana Project. But the new book serves as a fine sampler, and with its instruction, you’ll be able to try your hand at some of the projects it presents.

We are dumping carbon dioxide into the atmosphere faster today than at any time since the dinosaurs.
And not just by a little. By a lot. Ten times more, according to a new paper by University of Hawai`i researcher Richard Zeebe and collaborators.

What that means is serious uncertainty about climate change. We don’t know how fast change will come, but we know there will be a lot of it, they said.
In a paper published in the journal Nature Geoscience, the team, which included Zeebe, and co-authors Andy Ridgwell of the University of Bristol and University of California, and James Zachos of the University of California, described studying deep ocean sediments to make determinations about ancient climate.
The last time the planet faced a massive pulse of carbon dioxide, it was during the Paleocene-Eocene Thermal Maximum, 56 million years ago. The climate got hot back then, despite the fact that that big pulse contained far less carbon dioxide than we’re releasing today.
“Carbon release rates from human sources reached a record high in 2014 of about 37 billion metric tons of CO2. The researchers estimated the maximum sustained carbon release rate during the PETM had to be less than 4 billion metric tons of CO2 per year – about one-tenth the current rate,” said a press release from the University of Hawai`i. http://manoa.hawaii.edu/news/article.php?aId=7771
“Because our carbon release rate is unprecedented over such a long time period in Earth’s history, it also means that we have effectively entered a 'no-analogue' state. This represents a big challenge for projecting future climate changes because we have no good comparison from the past,” said Zeebe.
The impacts of the dramatic increase in the release of greenhouse gas, since it’s unlike anything experienced in the history of our species, will be remarkably difficult to model
“If you kick a system very fast, it usually responds differently than if you nudge it slowly but steadily," said Zeebe.
He suggested that while our grandkids will experience significant changes in climate, it’s our great-great grandkids who may suffer far more from issues like acid oceans, risen sea levels and warming atmosphere..
“Everyone is focused on what happens by 2100. But that’s only two generations from today. It’s like: If the world ends in 2100 we’re probably OK. But it’s very clear that over a longer timescale there will be much bigger changes,” Zeebe said.
