I haven't watched it yet, but I taped it. I'm fascinated to read that bit about the dendrochronology! I'll have to get back to you guys when I hear what time span that was and do a little research. Did they mention any reason for this meteorological wackiness? A volcano, perhaps?

The last time a supervolcano popped off was 74,000 years ago. Incidentally, human beings experienced a genetic bottleneck right at that time, getting down to less than 10,000 people. Our resident supervolcano here in the US, Yellowstone, is showing suspicious signs of blowing its top, which gives me the screaming willies! No one in the world is prepared for the years of darkness and the devestation to plant and animal life. Imagine 5 years of no crops....
