Years Without Summer
Cool Apple link of the day: predictions about the iPod from two years ago
There was a cool article in the December Analog about years without summer. The author didn’t mention 1816, but did go into some detail about 540 C.E. Other really bad weather years included 44 B.C., 207 B.C., 1159 B.C., 1628 B.C., 2354 B.C. (the Flood?), and 3195 B.C. The data came from tree rings.
