I bought a Kindle Paperwhite used, from a friend of mine, and it's been great -- quite an amazing device, really. But I was disappointed (not hugely, just a twinge) that it didn't come with audio features; I had hoped it would be my car audiobook player as well as book replacement -- hadn't researched enough, and it hadn't occurred to me that they would have removed such a good feature.
The poor climate may been one of many factors contributing to societal changes of the era, including widespread crop failures and famines in Central Asia that may have triggered migrations from the area to China and Eastern Europe, thus helping spread an episode of plague (depicted in this 15th century painting) that originated there.
Famine and plague, caused by extreme cold, illustrating starkly that cooling is a far greater threat to human survival than climate warming. Meanwhile, the Medieval Warm Period saw a flourishing of American Indian culture in the American southwest.
So why do our modern climate doom-sayers fear warming so much, when there is no data to justify that fear, and plenty of data to suggest otherwise.
