Hmmmm..........
Was thinkin I read somewhere that Iceland way back in.... think it was around 1100 A.D. was being used as farmland? Or was that Greenland? Suggesting that the climate around that time was a good deal warmer? Think there were reports from Ireland around that time of gloomy dark skys happening. some seem to believe there was a big meteor impact ot vaolcanic eruption thart created a nuclear winter type of invironment? Which lead to mini-iceage that we are just now coming out of? That mini-iceage contributed to the black plague along with many other changes in the europe of that time?
Some have even attribute the drastic climate changes of that peroid of time to the distruction of the cultures in the New Mexico/Arizona areas.
Information............ funny sort thing this "information" stuff.......... tends to make you think. The information doesn't always have to be true
