Thelasko shared this report from the BBC: A steady decline in the levels of ozone-harming CFC chemicals in the atmosphere has resumed, scientists say. This follows a recent, dangerous pause in that downward trajectory, which could have slowed the healing of Earth’s protective ozone layer. Atmospheric measurements published in 2018 pointed to illegal CFC production that was occurring in Eastern China….

Why Arctic sea ice has stalled, and what it means for the rest of the world
In the next few decades, scientists expect we’ll see an ice-free Arctic Ocean throughout the summer. That prospect got much closer in 2020, due in part to the exceptional summer heatwave that roiled the Russian Arctic. Source: https://earthsky.org/earth/why-arctic-winter-sea-ice-stalled-2020…
Did this mass extinction event trigger dawn of the dinosaurs?
New research suggests that a series of huge volcanic eruptions, 233 million years ago, led to a mass extinction event that heralded the dawn of the dinosaurs. Source: https://earthsky.org/earth/mass-extinction-event-trigger-dawn-of-dinosaurs…

Twitter Executive Is Also A British Army ‘Psyops’ Solider
“The senior Twitter executive with editorial responsibility for the Middle East is also a part-time officer in the British Army’s psychological warfare unit,” reports Middle East Eye: The 77th Brigade uses social media platforms such as Twitter, Instagram and Facebook, as well as podcasts, data analysis and audience research to wage what the head of the UK military, General Nick Carter,…
Two Mathematicians Solve Old Math Riddle, Possibly the Meaning of Life
pgmrdlm shares a report from Live Science: In Douglas Adams’ sci-fi series “The Hitchhiker’s Guide to the Galaxy,” a pair of programmers task the galaxy’s largest supercomputer with answering the ultimate question of the meaning of life, the universe and everything. After 7.5 million years of processing, the computer reaches an answer: 42. Only then do the programmers realize that nobody…
