The joker in me is inclined to respond "Stop with the lattes and avocado toast," but I'll presume you asked this in good faith. Here's one trick that has always been a foundation stone for my environmental history research--I analyze others' paleoscience datasets to answer different questions.

Now that the elation of publishing in the AHR has faded slightly, it's time to complain. They messed up ALL of the orthography of Rapanui names and words by using a regular rather than a rotated apostrophe ('okina) for the glottal stop. Proofs were correct! 😑

My favorite part our Easter Is AHR article is this partial reconstruction of the Rapanui Chronicle of Years. Nga'ara hosted elaborate tellings of Rapanui history using lists recorded on wooden tablets using rongorongo script before he died from TB following the Year of The Cough (1861-62). #envhist

ECOCIDE IS OFFICIALLY DEAD!!! The latest issue of the American Historical Review includes our massive article on Easter Island. It's part of a special issue on Histories of Resilience, with several articles focused on environmental history, Indigenous peoples, and the Global South. #envhist #histsci

Today in my Fb feed I have had news of fake AI book reviews in academic journals, fake AI bots attending Zoom office hours (at Harvard!), and of course the usual fake AI pictures, ads, and posts. Now I'm going to grade some fake AI student papers. The Industrial Revolution was shitty, too, I hear.
