An international team of scientists has discovered an extreme spike in radiocarbon corresponding to the year 12350 BC during the dusk of the last Ice Age. However, the strength of the event could not be assessed earlier because of the lack of an appropriate model. It has now been identified as the most powerful solar particle storm known to date—a colossal space weather storm that struck Earth 14,300 years ago. This recent finding expands the timeline and intensity of known solar activity and sets a new upper boundary for such solar phenomena.

    Thought this was interesting. It references another event I hadn’t heard of:

    The model confirmed that the detected solar event was approximately 18% stronger than the notorious AD 775 event—until now the strongest solar storm ever recorded in tree-ring archives.

    Over on HN, someone wrote this:

    On the other hand, would allergy sufferers be marvelling at the removal of all the dust and pollen? This would be like the outdoors becoming a giant anti-static dust remover.

    Not something I’ve heard about before, but that would be super interesting
