Yes, I’m referring to ocean currents and how I’ve understood it, is that they carry warm currents from the equator to the poles which is a main driver of warm weather cycling the planet.
Once the ocean currents stall we lose that warmth transference and everything subsequently freezes, and quickly. Not globally, but around the 30th latitude, north and south which is enough to make Europe, Asia, North America and half of Argentina near uninhabitable.
Correct me if I’m wrong but isn’t high C02 levels and global warming the reasoning behind the last Ice Age, circa. 11,000bc?
I’m not sure to be honest. I think both? I think ‘mini’ is the planet partially frozen except for the equatorial region, and the duration is a few thousand years opposed to perhaps tens or hundreds of thousands.
But I’m guessing based off the last one. It’s a good question. Either way, it’s a bad time for bald apes who’ve forgotten how to hunt.
