Although Clive Oppenheimer rejects the hypothesis that the eruption triggered the last glaciation, he agrees that it may have been responsible for a millennium of cool climate prior to the 19th Dansgaard-Oeschger event.
Walaupun Clive Oppenheimer menolak hipotesis bahwa letusan ini menyebabkan periode glasial terakhir, ia setuju bahwa letusan Toba menyebabkan iklim dingin selama satu milenium sebelum peristiwa Dansgaard-Oeschger abad ke-19.
