Google found this...but your excerpt link gives a page not found...

Archaeological and palaeoecological indications of an abrupt climate change in The Netherlands, and evidence for climatological teleconnections around 2650 BP

And I found it searching on 2650 BP.

Because I was trying to figure out a correlation between that date and the date on the Graphic that SH posted...

Can someone tell what is 2650 BP.

I suppose I should know....hmmm.

New concept to me, but this might be helpful:

BP = Before Present. :’) In radiocarbon dating, that would be Before 1950. :’)

When I got your ping I thought you were discussing British Petroleum...
