One of the major worries about climate tipping points is that it’s impossible for anyone, even the smartest of scientists, to say with any certainty how soon each of them might be reached or what will happen then.

Could one tipping point trigger another?

Yes, probably, but we don’t for sure which ones or exactly how. And we can’t really predict the timing or the magnitude of positive feedbacks and cascading effects, when multiple tipping points might overlap and reinforce and possibly amplify each other.

It’s not the fault of the scientists. They’re doing the best they can with the evidence and the tools they have. But it’s all quite unpredictable because they have never been in this position before. No one ever has.

What capitalist industry and commerce has done just in the last three decades, pumping nearly a *trillion* tons of CO₂ into the air, has no precedent. Never before in Earth’s history has so much carbon dioxide been added to the atmosphere over such a short period of time.

Because human lifespans are short, 30 years may seem like a long time to us — but in geological terms, that’s merely the blink of an eye. On such a scale, it’s literally as if we have detonated a bomb.

Welcome to the nightmare.

TITLE: How Valerie the Weiner Dog Survived 18 Months in the Australian Bush to Make it Home

URL: goodnewsnetwork.org/how-valeri

On an island south of Adelaide, a strange creature has been seen creeping through the bush. A long cylindrical body and long snout flanked by floppy ears are dead giveaways. But this wiener dog named Valerie isn’t lost anymore. After almost 18 months of living wild on Kangaroo Island, local police are poised to get […]

The Large Hadron Collider is getting an even larger successor

lemmy.world/post/27655474

lemmy.worldThe Large Hadron Collider is getting an even larger successor - Lemmy.WorldGENEVA (AP) — Top minds at the world’s largest atom smasher have released a blueprint for a much bigger successor that could vastly improve research into the remaining enigmas of physics. The plans for the Future Circular Collider — a nearly 91-kilometer (56.5-mile) loop along the French-Swiss border and below Lake Geneva — published late Monday put the finishing details on a project roughly a decade in the making at CERN, the European Organization for Nuclear Research. The FCC would carry out high-precision experiments in the mid-2040s to study “known physics” in greater detail, then enter a second phase — planned for 2070 — that would conduct high-energy collisions of protons and heavy ions that would “open the door to the unknown,” said Giorgio Chiarelli, a research director at Italy’s National Institute of Nuclear Physics.
