Unveiling Solar Storm Secrets: Tree Rings and the 1859 Carrington Event
Researchers from the University of Helsinki, in collaboration with other institutions, have studied the 1859 Carrington Event by analyzing radiocarbon concentrations in tree rings in Lapland, providing new insights into solar activity and its effects on Earth. This discovery could help in preparing for dangerous solar storms, as it offers a potential new way of investigating the frequency of Carrington-sized storms and understanding atmospheric dynamics and the carbon cycle. The study also sheds light on the impact of solar activity on radiocarbon production and transport, contributing to the development of increasingly detailed carbon cycle models.
