Supernovae haben möglicherweise in der Vergangenheit abrupte Klimaverschiebungen ausgelöst – und sie konnten wieder

TLDR:

* Astronomer Robert Brakenridge proposes a groundbreaking theory, published in *Monthly Notices of the Royal Astronomical Society*, asserting that past supernovae’s high-energy bursts directly triggered dramatic shifts in Earth’s ancient climate records.
* His detailed model reveals supernova radiation’s dual atmospheric assault: thinning the ozone layer, escalating harmful UV exposure, while simultaneously degrading stratospheric methane, critically dampening the greenhouse effect and inducing global cooling.
* Crucially, Brakenridge’s empirical analysis of 15,000 years of tree ring data, showing 11 carbon-14 spikes linked to supernovae, offers a vital framework for predicting and preparing humanity for catastrophic climate impacts from future stellar explosions like Betelgeuse.
