TL;DR: Megadroughts reconstructed over north-central Europe in the 11th and mid-15th centuries reinforce other evidence from North America and Asia that droughts were more severe, extensive, and prolonged over Northern Hemisphere land areas before the 20th century, with an inadequate understanding of their causes.
Journal ArticleDOI

TL;DR: The identification of distinct 14C excursions in 484 individual tree rings enable the authors to confirm the dating of 44 dendrochronologies from five continents, and suggest a global exposure to strong solar proton radiation.
Journal ArticleDOI
Rapid increase in cosmogenic 14C in AD 775 measured in New Zealand kauri trees indicates short-lived increase in 14C production spanning both hemispheres
D. Güttler,Florian Adolphi,Juerg Beer,Niels Bleicher,Gretel Boswijk,Marcus Christl,Alan G. Hogg,Jonathan G. Palmer,Christof Vockenhuber,L. Wacker,Jan Wunder,Jan Wunder,Jan Wunder +12 more
TL;DR: In this paper, Miyake et al. presented the first annually resolved Southern Hemisphere (SH) C-14 record spanning the interval AD 760-787, using New Zealand kauri (Agathis australis) chronology wood.
Journal ArticleDOI
Eleven-year solar cycles over the last millennium revealed by radiocarbon in tree rings

TL;DR: In this paper, the authors presented a continuous, annually resolved atmospheric 14C concentration (fractionation-corrected ratio of 14CO2 to CO2) record reconstructed from absolutely dated tree rings covering nearly all of the last millennium (ad 969-1933).
