Absence of Evidence for a Meteorite Impact Event 13,000 Years Ago 
Science Daily, Dec. 14, 2009) â An international team of scientists led 
by researchers at the University of Hawaii at Manoa has found no 
evidence supporting an extraterrestrial impact event at the onset of 
the Younger Dryas approximately 13,000 years ago.
