Thank your lucky stars to be alive on Earth at this time. Our planet is usually in a deep freeze. The last million years have cycled through Ice Ages that last about 100,000 years each, with warmer slivers of about 10,000 years in between.
We are in-betweeners, and just barely — we live in (gasp!) year 10,000 or so after the end of the last ice age. But for our good fortune, we might have been born in the next Ice Age.
Our luck is even better than that. Those 10,000-year warm spells aren’t all cosy-warm. They include brutal Little Ice Ages such as the 500-year-long Little Ice Age that started about 600 years ago. Fortunately, we weren’t around during its fiercest periods when Finland lost one-third of its population, Iceland half, and most of Canada became uninhabitable — even the Inuit fled. While the cold spells within the 10,000 year warm spells aren’t as brutal as a Little Ice Age, they can nevertheless make us huddle in gloom, such as the period in history from about 400 AD to 900 AD, which we know as the Dark Ages. We’ve lucked out twice, escaping the cold spells within the warm spells, making us inbetweeners within the inbetween periods. How good is that?
