The above article stated:

“Two studies published in 2006 show that the same 
thing happened again 8200 years ago, when the 
Northern hemisphere went through another cold spell”

The New Scientist article about these two studies is:

Broken ice dam blamed for 300-year chill by Kurt

“In the new papers, one in the Proceedings of the 
National Academy of Sciences and the other in the 
current Quaternary Science Reviews, two teams of 
researchers using different computer models say 
that both models show that such a freshwater flood 
could shut down ocean circulation in a way that is 
consistent with temperature data from the time.” 

These papers demonstrate that processes other than 
extraterrestrial impacts can cause events very similar
to the Youmnger Dryas interval.  They are:
