Archeologists disprove deleterious AGW

ScienceDaily (Jan. 27, 2011) — Artifacts unearthed in the United Arab Emirates date back 100,000 years and imply that modern humans first left Africa much earlier than researchers had expected, a new study reports. In light of their excavation, an international team of researchers led by Hans-Peter Uerpmann from Eberhard Karls University in Tübingen, Germany suggests that humans could have arrived on the Arabian Peninsula as early as 125,000 years ago -- directly from Africa rather than via the Nile Valley or the Near East, as researchers have suggested in the past.

...

The team of researchers, including lead author Simon Armitage from Royal Holloway, University of London, discovered an ancient human toolkit at the Jebel Faya archaeological site in the United Arab Emirates. It resembles technology used by early humans in east Africa but not the craftsmanship that emerged from the Middle East, they say. This toolkit includes relatively primitive hand-axes along with a variety of scrapers and perforators, and its contents imply that technological innovation was not necessary for early humans to migrate onto the Arabian Peninsula. Armitage calculated the age of the stone tools using a technique known as luminescence dating and determined that the artifacts were about 100,000 to 125,000 years old.

"These 'anatomically modern' humans -- like you and me -- had evolved in Africa about 200,000 years ago and subsequently populated the rest of the world," said Armitage. "Our findings should stimulate a re-evaluation of the means by which we modern humans became a global species."

Uerpmann and his team also analyzed sea-level and climate-change records for the region during the last interglacial period, approximately 130,000 years ago. They determined that the Bab al-Mandab Strait, which separates Arabia from the Horn of Africa, would have narrowed due to lower sea-levels, allowing safe passage prior to and at the beginning of that last interglacial period. At that time, the Arabian Peninsula was much wetter than today with greater vegetation cover and a network of lakes and rivers. Such a landscape would have allowed early humans access into Arabia and then into the Fertile Crescent and India, according to the researchers.

1) Climate change occurs even without technology.

2) Assumptions that climate change is bad are unfounded. For all we know the climate change the greens would inhibit may be the change that returns the Arab peninsula to fertile lands suitable for agriculture.
According to the Bible, "know" means "yes."

How to explain the Eskimo crossing over from Russia???  Did they come in boats or walk on a land bridge??

Then the controversy about South America on why so much of their buildings were so much like those in Egypt.

Climate and warm winds may in fact allowed for trans Atlantic travel, but the question causes the PHD'S to get into a nose punching argument.

The Pacific we know allowed some fortunate few to travel a few thousand miles, was it the climate that allowed them to do do with westerly winds or by accident??
