Response - Tephrachronology is a precise and well established procedure. The Laarcher See Volcano is dated to within 40 years, 200 years before the Younger Dryas, and for you to imply that anyone in the geological community subscribes to your personal hypothesis that the Laarcher See volcanic eruption was related in any way to the Younger Dryas Chronozone - is simply false. I have no more plans to attempt to either educate you or edit your ramblings here.
