These two species of seal migrate north along Greenland shores in the spring, and Smiarowski thinks the Norse likely caught them with boats and nets or clubs. In , NABO researchers clinched the case that the Greenlanders ate a marine diet by analyzing human bones in Norse graveyards. Animals that live in the sea have ratios of carbon and nitrogen isotopes that differ from those found in terrestrial animals, and this isotopic signature is passed on to the people who eat them.
The Norse bones show that as the settlement developed from the 11th to the 15th century, their diet contained ever more marine protein. Far from clinging to livestock as temperatures fell, the Norse instead managed a successful subsistence system with "flexibility and capacity to adapt," wrote the author of the paper, Jette Arneborg from the National Museum of Denmark in Copenhagen. Nor were the Norse incompetent farmers, as Diamond and others have suggested. Soil geographer Ian Simpson of the University of Stirling in the United Kingdom says previous studies overestimated the Norse contribution to erosion in Greenland.
New pollen and soil data show that the Norse allowed fields and what little forest existed to recover after tilling and turf cutting. And in analyses of soil and lake sediment cores, researchers have found chemical and paleoecological clues indicating that Norse farmers skillfully maintained pastures with manure fertilizer and irrigation ditches.

Such findings, along with the ivory evidence, have transformed ideas about Norse society, says McGovern, whose beard is now white. It's exciting to get a chance to revise your old thinking before a younger colleague can," he says. Now, we consider them hunters who farmed.

In the 10th and 11th centuries, the Norse crossed the stormy Atlantic to Greenland in vessels like this 9th century Viking ship found in Norway. It was a sustainable lifestyle for hundreds of years. But in the 13th century, economics and climate began to conspire against the Norse. After , a cooling climate posed multiple threats to a marine-oriented society reliant on seal and walrus. Global average temperature fell by about a degree during the Little Ice Age, although scientists have struggled to quantify local cooling.
Even before the big chill set in, The King's Mirror describes ships lost and men who perished in ice. Historians and climatologists agree that as the cold spell continued, ice would have clogged the seas farther south and for longer each year, disrupting voyages. And concentrations of salt particles in glacier cores indicate that seas became stormier in the 15th century. Norsemen hunting migratory seals or walrus on the high seas would have been at increasing risk. The nomadic Inuit, by contrast, hunted seal native to the fjords, and rarely embarked on open-ocean hunts or journeys.
Not only did the climate disrupt trade, but the market did, too. Around , the value of ivory in Europe fell as tusks from Russian walrus and African elephants flowed into the continent. Even as surviving from marine resources became more difficult, the growing season on land shortened, and the meager pastures yielded even less. But soil and sediment analyses show that the farmers, too, tried to adapt, Simpson said, often fertilizing and watering their pastures more intensively as temperatures dropped.
Instead, he says, these "pretty good managers" actively adapted to the cooling climate. In the end, however, their best efforts fell short. At the grand bishop's seat of Gardar, 35 kilometers away by boat from the modest farm at Tasilikulooq, grass grows around the ruins of a cathedral, the bishop's residence, and myriad other buildings probably built by stonemasons shipped in from Norway. Stone shelters here once housed more than cows—a sign of power in medieval Scandinavia. If the Greenland settlement was originally an effort to find and exploit the prized natural resource of ivory, rather than a collection of independent farmers, the society would have needed more top-down planning than archaeologists had thought, says Christian Koch Madsen of the Danish and Greenlandic National Museums in Copenhagen.
His work and other research support that notion by revealing orchestrated changes in the settlement pattern as the climate worsened. Madsen carefully radiocarbon dated organic remains like wood from the ruins of Norse farms. The dates show that Gardar, like other rich farms, was established early.
But they also suggest that when the first hints of the Little Ice Age appeared around , dozens of outlying farms were abandoned, and sometimes reestablished closer to the central manors. The bones in middens help explain why: As temperatures fell, people in the large farms continued to eat beef and other livestock whereas those in smaller farms turned to seal and caribou, as Diamond had suggested. To maintain their diet, Greenland's powerful had to expand labor-intensive practices like storing winter fodder and sheltering cows.

He thinks that larger farms got the additional labor by establishing tenant farms. The stresses mounted as the weather worsened, Madsen suspects. He notes that the average Norse farmer had to balance the spring- and summertime demands of his own farm with annual communal walrus and migratory seal hunts. Deprivation in lower societal strata "could eventually have cascaded up through the system," destabilizing large farms dependent on tithes and labor from small ones. The disrupted ivory trade, and perhaps losses at sea, couldn't have helped.
The Greenland Norse simply could not hold on. It adds up to a detailed picture that most archaeologists studying the Norse have embraced. But not everyone agrees with the entire vision. With a number 1 guitar steel string over an ice block about 40x25x25 mm in size and weighted with 4 kg of water in two plastic milk bottles at room temperature, the wire cut through in 25 minutes, the ice re-freezing behind the cut. However, with the apparatus in a chest freezer, there was absolutely no movement in 8 hours. The pressure exerted by the wire?
About tonnes per square metre, which is enough to reduce the melting point of ice less than 0. As a matter of interest, a P—38 exerts a pressure of only 0.

Life in the Great Ice Age. Evolution: The Greatest Deception. Wonders of Creaton: Geology Book. Hard cover. Dan M. US May 26th, I love aircraft especially the WWII variety. I lived and worked in Alaska for 32 years, 16 of them on aircraft until my accident that retired me so I know a thing or two. Glaciers are swallowing planes up there as well, just not as fast or as deep, smaller ice fields.
I remember reading an article years ago, maybe the same one stating that sun light and pressure caused these planes to sink into the ice. I didn't believe it then and I find it ridiculous now. I didn't think about the nose heavy condition of the planes that would have caused them to nose over at that time so thanks for pointing that out.
I should have known since planes sink in water nose first. Another point is why weren't the heavier Bs deeper in the ice if pressure was the result. The article mentioned sun light also but that could only account for several feet until it was blocked out. Secular scientists use ice core samples to calibrate sea floor sediment dating claiming long ages.
I guess rapid glacier buildup being the obvious conclusion for these planes being so deep in the ice topples all that, but secularists will never admit it. Once you throw off the evolutionary brainwashing, things start to make sense. Ferrol H.

This is the type of articles I love to read. What is does is just reinforce what I already know my Lord has taught me! Love it keep up the good work! Luke G.
NZ May 25th, ZA May 25th, Mr Brombley's insight quoted at the end of the article is an excellent example of pro-actively countering the evolutionist die-hard's warped hatred of God! Yes, those not in Christ hate God and that which He revealed to us. They bow to anything BUT God - evolutionist conjectures are but one example. See Exodus ! Brendan J.

AU May 25th, I remember reading this article many years ago with great enjoyment and still loved reading it again today. The mixture of medieval like survival with the odd bit of advanced technology is very effective and quite plausible while this is further complicated by past events I won't spoil it by saying more.
Characterisation is handled well and the very minimal back-story is told through short descriptive narrative - just enough to provide an insight without slowing down the pace. The story is a nice mix of survival of the human race and miss-use of technology along with alien intervention all complicated from the harsh conditions of the earth and the warring factions of the survivors. As with the previous novel there isn't really one central protagonist, instead it's the journey that takes centre stage with the characters more a supporting cast. As such this is a plot led rather than character led story and as a plot led story it works very well.
I would recommend reading the first 2 novels The Sacred Protocol and Divine Extinction before reading The Ice Wars of Dominia as it does make a lot more sense that way and there are a number of references to past events. There are some great ideas presented here - the biggest of which is humanities pre dereliction to self destruction, I loved the way that earth is completely unrecognisable from the way it was at the very beginning of the story in The Sacred Protocol.
