I saw one of these beetles today and had some questions about what I saw. This post was helpful.
For the past few weeks, I’ve been seeing dazzling green Six-spotted Tiger Beetles (Cicindela sexguttata) along wooded trails, and even on the paths through my shade garden. I think of these brightly colored beetles as one of the harbingers of spring. They are most commonly seen from spring through early summer in openings in or next to wooded areas.
This eye-catching beetle is named for the spots on its elytra (outer wings), although the number of spots is variable; an individual may have more or less than six spots.
Sometimes called the Six-spotted Green Tiger Beetle, its coloration is most often a vivid metallic emerald green, but in some individuals it may take on a bluish hue.

A “must read”, imo.
Yuval Harari’s writings explode many fictions on which modern civilization is based. However, his own unacknowledged fictions perpetuate dangerous myths. In this article, I urge Harari to recognize his own implicit stories, and by doing so, step up to his full potential role in helping shape humanity’s future.
When Yuval Noah Harari speaks, the world listens. Or at least, the world’s reading public. His first two blockbusters, Sapiens: A Brief History of Humankind, and Homo Deus: A Brief History of Tomorrow, have sold 12 million copies globally, and his new book, 21 Lessons for the 21st Century, is on bestseller lists everywhere. His fans include Barack Obama, Bill Gates, and Mark Zuckerberg, he’s admired by opinion shapers as diverse as Sam Harris and Russell Brand, and he’s fêted at the IMF and World Economic Forum.
Harari is fêted at the World Economic Forum and many other…

Worth reading and checking out the embedded link to the PNAS paper, Trajectories in the Earth System in the Anthropocene.
On July 31, 2018, a paper was published in the Proceedings of the National Academy of Sciences which should create a shiver of fear in all humans everywhere. The paper, Trajectories in the Earth System in the Anthropocene by Steffen et..al., explains how human-induced warming is rapidly approaching levels that may trigger positive climate feedbacks which could greatly accelerate the warming already plaguing the world by causing record floods, deadly heat waves and droughts, increasing tropical diseases, forest fires, more intense and damaging storms, sea level rise, coral bleaching, acidification of oceans, all of which are contributing to increasing the number of refugees which are destabilizing governments around the world.
The Steffen et. al. paper also describes how the positive feedbacks depicted in the following graphic, once triggered could initiate other feedbacks creating a cascade of positive feedbacks, each of which could speed up the warming which is already…
