AKA Dendrochronology works on a global scale!

In an unprecedented collaboration of tree ring and radiocarbon researchers around the world have come together to investigate the AD 774 and 993 radiocarbon excess.

In a nutshell they find that tree ring records accurately cross date globally and that the 774 and 993 cosmic events are recorded coherently in each chronology, with the events likely occurring in the boreal summer of AD 774 and Boreal spring AD 993 (give or take).
