Mayan Calendar Party Time?

See also the article and discussion here:

The charts on the above pages indicate that we are now out of danger in terms of the major comets that plagued Earth over thousands of years (from the end of the last Ice Age). However, that conclusion assumes that scientists have correctly estimated the elapsed time (using tree-rings and ice-core rings) from the last world-wide disaster (circa 1150 BC) until now!
