Study: Humans Drove Final Nail into Mammoth Coffin
Clara Moskowitz LiveScience Staff Writer LiveScience.comWed Apr 2, 9:31 AM ET
Humans may have struck the final blow that killed the woolly-mammoth, but climate change seems to have played a major part in setting up the end-game, according to a new study.
Though mammoth populations declined severely around 12,000 years ago, they didn't completely disappear until around 3,600 years ago. Scientists have long debated what finally drove the furry beasts over the edge. Researchers led by David Nogues-Bravo of the National Museum of Natural Sciences in Spain used models of the climate, as well as models of woolly-mammoth and human populations, to study the relative importance of various factors leading to the mammals' demise.
The scientists published their results in the journal PLoS Biology.
The team found that the brunt of the damage done to mammoths was due to Earth's warming weather around 8,000 to 6,000 years ago. Since Earth was coming out of a glacial period at that time, temperatures were climbing and recasting the planet's landscape, and the mammoth's preferred habitat, steppe tundra, was vastly reduced.
The researchers calculated the temperature window in which mammoths can survive by matching known fossil specimens with climate models. They determined the temperature at the time each mammoth specimen lived and combined the data to get an overall picture of the animals' preferred climate range.
The team found that by 6,000 years ago, mammoths were relegated to 10 percent of the habitat that had previously been available to them 42,000 years ago when the glaciers were at their largest size and greatest extent.
But climate doesn't seem to explain the entirety of the mammoth's extinction. These hardy animals had survived, barely, a previous interglacial period of planet warming around 126,000 years ago.

Someone, somewhere, feels guilty about this.
Not me. I'm sure I would not be here were it not for my Nordic and Celtic ancestors having mammoth pot roast dinners on Sundays.
It was 15 feet higher here on the west coast of the United States. Lowlying reas along the coastline here were unindated with seawater, creating deep inlets into mountainous areas, or what today look like abandoned beaches high above today’s sealevel beaches.
15000 years ago the paleo shoreline was 23-25 miles further west of today’s present shoreline.
“mammoth pot roast dinners”
I’d go for Mammoth Teriyaki.
OBTW, didn’t the modern discoverers of the frozen mammoths actually feast on some of the 10,000 year old meat?
“There are a number of puzzling mysteries...the extinction of the mammoths and saber-toothed tigers, the vanishing of Indian tribes,...Carolina Bays,...wild temperature swings at the end of the Ice Age, and the cause of huge underwater landslides that sent massive (1000 ft. tall) tsunamis racing across the oceans millenia ago...” The Cycle of Cosmic Catastrophes, by Richard Firestone, Allen West, and Simon Warwick-Smith, will answer those questions and more. A really sobering read, particularly when you realize there is nothing people can do to prevent such an event.
We shouldn’t be blaming humans for the mammoth’s demise, as humans too were eliminated in large numbers at that time. 41,000 years ago a star supernovaed. It took a while for the material from that blast to arrive on Earth, and when it did, the results were catastrophic. This book details all the scientific evidence in layman’s terms.
Hope this helps in settling the arguments.

Actually, it was me.
These "experts" have two things in common. One -- they can, with absolute confidence, examine a tiny toe bone and invent a whole social structure for the individual, including what he had for breakfast, his family attitudes, where he got water and food, and how he viewed strangers from another culture - like a liberal from Berkeley would, with input from sister Theresa, complete with touchy-feely psychobabble.
Second, they treat their theories as absolute faith. The zealots of the promised land had nothing over these guys.
The only thing that remains a mystery, and should fuel generations of pschiatrists and psychologists, is the need for these parasites, usually subsisting on grants and foundation money, to blame man for everything in the history of the cosmos. Without hesitation, doubts or qualifiers of any kind.
Needless to say, man has existed only to somehow screw up nature, and man has no rights whatsoever to assume his role in the big picture. That would require, well --- a giant leap of faith.
Freeze-dried Mammoths? Can’t we just add water, stir, and bring them back?
Evidently, they’re edible in Siberia.
And there are so many that froze instantly with fresh greens in their stomachs, that they have become a nearly limitless source of ivory for the trade.
That wasn’t climate change in years, months, or even weeks—they would have migrated, starved, rotted. That was climate change in a day. Had to be a huge catastrophe, I’ve wondered for years what happened, and I guess we’ll never know.
Siberia is one of the most fascinating areas on earth, under the ice....
