By Tyler Durden: A new study, based on the analysis of growth rings in ancient trees, suggests that the most powerful solar storm on record slammed into Earth approximately 14,300 years ago. Should a storm of that intensity strike today, modern society would instantly collapse.
Researchers from the Collège de France, CEREGE, IMBE, Aix-Marseille University, and the University of Leeds published the new study in the Royal Society A journal. They measured radiocarbon levels in ancient trees preserved within the eroded banks of the Drouzet River near Gap, in the Southern French Alps, and found "tree trunks, which are subfossils – remains whose fossilization process is not complete – were sliced into tiny single tree-rings. Analysis of these individual rings identified an unprecedented spike in radiocarbon levels occurring precisely 14,300 years ago."
