However, that are not recorded in historical documents can seldom be dated exactly. Here we use annually resolved radiocarbon (14C) measurements isolate 775 cosmogenic 14C peak a subfossil birch tree was buried glacial outburst flood southern Iceland. We employ absolute time marker date subglacial volcano at late 822 early 823 argue correlation between conspicuous sulfur anomaly evident Greenland ice cores, which follows wake an even larger signal (ca. 818–820 CE) as yet attributed known eruption. An abrupt summer cooling 824 CE, tree-ring reconstructions Fennoscandia Northern Hemisphere, suggests climatic response Written sources from Europe China corroborate our proposed ring–radiocarbon–ice core linkage but also point combined effects occurring during period. Our study describes oldest precisely dated, high-latitude reveals impact extended phase forcing 9th century. It provides insight into existence prehistoric woodland cover nature volcanism several decades before permanent settlement began.
