The Carrington Event of 1859, an enormous solar storm, was just recently studied through radiocarbon concentrations in tree rings, revealing new insights into solar activity and its impacts on Earth.”Radiocarbon is like a cosmic marker describing phenomena associated with Earth, the solar system, and outer area,” states Markku Oinonen, Director of the University of Helsinkis Laboratory of Chronology, who headed the study.Mapping solar stormsA solar storm corresponding to the Carrington occasion in modern-day times would interrupt electrical and mobile networks and trigger major issues for satellite and navigation systems, leading to problems in, for example, air traffic.”The dynamic climatic carbon transport model was specifically established for describing geographical differences in the distribution of radiocarbon in the atmosphere,” says Postdoctoral Researcher Kseniia Golubenko from the University of Oulu.What was considerable in the just recently released research study was how the radiocarbon material of trees in Lapland differed from that of trees at lower latitudes.”Its possible that the excess of radiocarbon caused by the solar flare was mostly transported to the lower environment through northern areas, contrary to the general understanding of its motion,” muses Doctoral Researcher Joonas Uusitalo from the Laboratory of Chronology.Other sources of radiocarbon”Its likewise possible that the cyclic change in the production of radiocarbon in the upper atmosphere triggered by the variation in solar activity has actually resulted in the local differences on the ground level seen in our findings,” Uusitalo adds.According to Uusitalo, the dominant portion of radiocarbon is produced by galactic cosmic rays coming from outside the solar system, even though remarkably strong solar storms produce private bursts of the isotope in the atmosphere.
