70,000 years ago was just about the same time as a huge super volcano explosion near Java or Sumatra (I forget which).

Many scientists believe that human beings were almost wiped out at that time because the atmospheric dust reflected back much of the Earth’s sunlight.

The earth was already in an Ice Age at that point in time.

Actually, no. Most recently:

• No Volcanic Winter In East Africa From Ancient Toba (Super-Volcano) Eruption [2018]
• Star Blasted Through Solar System 70,000 Years Ago [2015]
• Modern Humans in India Earlier Than Previously Thought? [2013]
• Archaeogenetic research refutes earlier findings [2013]
• Toba super-volcano catastrophe idea 'dismissed' [2013]

I was about to ask, “What does this have to do with Toba?” But you beat me to it. True, the earth was already in an Ice Age at that point, but if you look at long term temperature charts you can see a significant dip after 74,000 ya.
