Bowerthane:
 Thanks Blackdragon.
 
 
“[ I]n 993, a cosmic radiation event, probably an enormous solar storm, caused a huge spike in atmospheric carbon levels that can clearly be measured in tree ring samples.”

 
 Has anybody heard of this “cosmic radiation event”?   Has it any consequences in Anglo-Saxon archaeology, that anyone has heard of?


Phyllis:
I admit I was assuming the main consequence was a signature in tree ring dating - I'm not sure what else would be apparent! But I'm not good at science stuff
