A mini ice age means all the non-Europeans would die because they can't acclimatise to cold weather. Bring it on, I say. > if it hits a specific spot in or off east africa a new fault line could spread across africa lead to increased tectonic activity on a global scale and it would kill all of east africa and half of saudi arabia along with a massive fault with new volcanoes opening in central africa. I'm voting for this one, personally.
