Eastern Alps may have been ice-free in the time of Ötzi the Iceman
There were many passes also in the Alps that were unusable for the last 200 years that have been used extensively in various older periods of our history. In Norway, 1000-year-old passes are being discovered today together with remains of waystations and a lot of other traces of frequent human use. They were technologically far less advanced than we are today and still managed to pass them better than we can today. This means that it must have been a lot warmer than today and not only for a year. The evidence is loud and clear. But the alarmists won’t even respond to it. Time to rub it in their faces like a dog gets to taste his own feces when he defecates where he is not supposed to.
