Perhaps the weather pattern that exists during the ice-age conditions are the ones that favor a civilization that isn't in state of survival mode that always has to involve the elimination of other people as there are only so many supplies to go around.
Nice to see the ozone hole is closing up, perhaps some will make it down to the surface of the earth. Look up the history of O2 and perhaps the highs and lows can be matched to certain times in the earth's past as far as how smart people were back then as it ranged from 35% to about 15% and changes that drastic are know to have different effects all by them-self.
Perhaps the 'hoarding syndrome' is a manifestation that comes with the brain being starved of O2 rather than some group is trying to kill you by taking food out of your mouth. Neanderthal were around in the last major ice age and perhaps their larger size was from more food being available as well as larger noses made getting more air that was already higher in O2 as the inhabitable places were covered in plants and trees all year around. Lets assume more O2 makes you smarter rather than delusional as that is a trait that comes around only when the brain is dying from lack of O2. People will do crazy things when they think their like is under threat and when the last ice-age ended it did mean that as food production was cut and places to live were inhabitable part of the year so starvation was a real hazard. Having so much wine that it is worth $0.01/gallon is not going to make all of society really drunk. It means the richest and the poorest person can drink the same wine should they choose to do so. Today the best stuff is hoarded and protected with deadly force.
My area was once connected to Loch Ness Scotland and had dinosaurs walking around it.
Really?? That sounds a lot like the expanding earth theory, the one that also says the wjole UK and Ireland will be taken farther out to sea before sinking under the waves thanks to the subduction from the Icelandic Rift going under the body.
60M years ago the oceans (and earth) were about 1/3 the size they are now so food and air quality were better as was gravity as a smaller globe naturally spins faster and that allows for larger beings. Being heavier in our time due to a larger body and a slower spin rate they would not have been able to stand let alone run and jump and fly. (higher density atmosphere and near 100% humidity makes flying easier)
