What Effect Coming Ice Age on North of 30th Parallel Boating?

"If you asked most Indians in some respectful manner, I think you'd find most of them wouldn't have a problem reconciling a philosophical belief that we have lived here since time immemorial with natural evidence that we arrived here at least 20,000 years ago. Why shouldn't they both be true? The Creator is great, we don't always understand the whole world."

I wonder if the kayak or even the umiak dates that far back.

We have been thinking the same thoughts......
I have been perusing the the new crop of bathemetric imagery & wondering if we are going to see new coast lines to the edge of the continental shelf during the upcoming glacial period.
Have you seen it stated that this distinct edge has anything to do with ice age sea levels Hoyte?

Take a look at these maps and make sure to click on image to see higher res:

Take a look close up of the Gulf of Mexico in the second global map- its a fascinating image.
I would post it if I knew how to capture a part of that map....

 

Here we go....

 

Thanks

 

Yes, it looks very close to the map I posted on the previous post #201 second image.

 

Good job, bntii. I tried to post that but the uploader thing said 2.4Mb was too big a file. Thanks.

 

The challenges in South Africa were great as well 20000 years ago.: http://www.mongabay.com/reference/country_studies/south-africa/HISTORY.html

"Roughly 20,000 years ago, South Africa, still in the grip of the world's last Ice Age, was occupied by people now known as San. Remnants of San communities still survive today as so-called Bushmen (now considered a pejorative term) in the Kalahari Desert. The San, who developed their society over thousands of years in isolation, speak a language that includes unique "click" consonants, are smaller statured, and have lighter skin pigmentation than the Bantu (see Glossary) speakers who later moved into southern Africa."

 

This very interesting article has a new discovery listed in the last paragraph.: http://anthro.palomar.edu/homo2/mod_homo_4.htm

"NEWS: In March 2010, Johannes Krause of the Max Planck Institute for Evolutionary Anthropology in Germany announced that the mitochondrial DNA recovered from a 50,000-30,000 year old finger bone found at a Siberian cave site known as Denisova is from an up to now unknown form of human (now referred to as the Denisovans). This possible new variety or even new species of human lived at the same time as Neandertals and early modern humans (March 24, 2010 Nature). About 4-6% of the DNA of the living New Guineans and other Melanesians appears to be inherited from the Denisovans (December 23, 2010 Nature). This would imply that their ancestors interbred to some extent."

 

eustasy (yo͞oˈstə-sē)
"A uniform worldwide change in sea level caused especially by fluctuations in the amount of water taken up by continental and polar icecaps, or by a change in the capacity of ocean basins."




"The medium gray shading shows the modern-day coastlines of eastern North America and the Gulf of Mexico. The dark gray shading shows the same coastlines as they may have appeared during the warm climate interval of the Pliocene Epoch. The light gray shading shows the same coastlines as they may have appeared during the most recent ice age when much of the world's ocean water was locked up in continental ice sheets."

 

We are better off with higher sea levels than with ice-age simply because of food supply. Hillbillies such as I could have waterfront property without leaving Appalachia. How great would that be? Canada would be able to grow more wheat and even corn, bwecoming the breadbasket of the world, along with Russia.

 

Of course, The Bahamas would have to move to Valdosta. In an ice-age the Bahamas would be relatively huge, and could be the new Atlantis.
