> Six diverse historical occurrences, from archaeological sites to natural disasters, have thus been dated to a specific year, using Miyake events as benchmarks and counting tree rings. For example, wooden houses in the Viking site at L'Anse aux Meadows in Newfoundland were dated by finding the 993 CE Miyake event and then counting tree rings, which showed that the wood is from a tree felled in 1021 CE.[

13000 years ago seems like a special moment for a few events. Is it possible that say a volcano eruption, or a meteor strike saturates the atmosphere and normal cosmic ray interaction with soot and so on can attribute to what they detect in trees?
