I... am afraid that I do not have the answer to your question. In fact, the science of it goes far beyond my ken, although it is quite interesting. But it would follow that if we are in an ice age larger than the previous one, it would be the Middle Ice Age.
Doesn't it, though? Although I much prefer being huddled in my blankets, not sick, and watching the snow fall. Which I suppose is only natural. I have found myself wondering what it would be like to experience such a significant snowfall outside of the city, in a rural area, how it would differ. Would on be moved to write bucolic wintery scenes, intended to warm one's soul?
