Killing space blast 'off the hook'

At school I was taught that it was humans that were responsible for the disappearance of mammoths etc in North America. I'd never heard of the impact theory....and now that I hear of it, it's being challenged. pfft. Think I need more schooling.

The most common theories I heard are meteor impact, extreme climate change and man-made extinction. Man-made is certainly the likely reason as it isn't the first time it happened.

My great grandmother told me that when she was young and living in Alaska during the gold rush, they would use pressurized water to degrade glaciers and frozen ground and that ocassionaly they would uncover a mamoth that had been frozen solid. It would begin decaying as soon as it started thawing out and could be smelled for miles around. So in other words these mamoths had been frozen solid before they could even start decaying. The only way that could be explained (I think) is if they were suddenly frozen by something like the extreme cold fronts that were in the movie The Day After Tomorrow... [More]

What many people seem to forget is that during the ice age huge lakes were formed because rivers got dammed by ice (in Siberia there was such a lake that was twice the size of the present Caspian Sea, and there are traces that point to catastrophic floodings when the ice dams breached). When an ice dam breached because the pressure of the water on the dam became to great, the resulting huge flash flood could have drowned those mammoths in freezing cold water. The carcasses of these animals would finally come to rest on another ice field or glacier further down stream of the flood, and be froze... [More]

Blue Sky Studios documented that flood scenario in their 2006 film "Ice Age: The Meltdown"
