A scare tactic of the global warming hoaxers is “man-made warming” will cause the polar ice caps to melt so drastically they will pass some sort of “tipping point” and like my hair, will never be able to regrow. Of course in my case it is nothing to worry about because I live at the coast, which according to the hoaxers, by the time the ice caps disappear, will be under water anyway.
A new report detailed in the latest issue of the Journal of Science, indicates that their probably isn’t any “tipping point.” They prove that as recently as 6,000 years ago (that is recent in geologic time) polar ice caps were half the size they are today and have rebounded very nicely.
We present a sea-ice record from northern Greenland covering the past 10,000 years. Multiyear sea ice reached a minimum between ~8500 and 6000 years ago, when the limit of year-round sea ice at the coast of Greenland was located ~1000 kilometers to the north of its present position. The subsequent increase in multiyear sea ice culminated during the past 2500 years and is linked to an increase in ice export from the western Arctic and higher variability of ice-drift routes. When the ice was at its minimum in northern Greenland, it greatly increased at Ellesmere Island to the west. The lack of uniformity in past sea-ice changes, which is probably related to large-scale atmospheric anomalies such as the Arctic Oscillation, is not well reproduced in models. This needs to be further explored, as it is likely to have an impact on predictions of future sea-ice distribution.
Danish researchers analysed ancient driftwood in north Greenland which they feel is an accurate way to measure ancient ice loss. The team found evidence that ice levels were about 50% lower 5,000 years ago. Under the Global Warming hoax, that would have meant that the Ice Caps would have continued melting to the point that they would have dissipated forever (like wide ties and polyester leisure suits). Because the ice caps returned to full health the Danish scientists observe that a tipping point under current scenarios is unlikely.
… a Danish team believes it has found an indirect method that gives a clear picture of the ice loss dating back 11,000 years.
Dr Svend Funder from the Natural History Museum of Denmark led several expeditions to inhospitable regions of Northern Greenland. On these frozen shores the Danish team noticed several pieces of ancient driftwood. They concluded that it could be an important method of unlocking the secrets of the ancient ice.
“Driftwood cannot float across the water, it has to be ferried across the ocean on ice, and this voyage takes several years, which means that driftwood is actually a signal of multi-year sea ice in the ocean and it is this ice that is at risk at the moment” said Dr Funder.
Carbon dating was used to determine the age of the wood. And figuring out its origins also yielded important information.
“It’s so lovely that drift wood from Siberia is mainly larch and from North America is mainly spruce. So if we see there was more larch or spruce we can see that the wind system had changed and in some periods there was little spruce and in other periods there was lots,” he said.
Wind delay? As well as the driftwood, the scientists mapped beach ridges for 500km (310 miles) along the coast. This proved that at one time the waves had reached the shore unhindered by the ice.
Dr Funder and his team say their data shows a clear connection between temperature and the amount of sea ice. The researchers concluded that for about 3,000 years, during a period called the Holocene Climate Optimum, there was more open water and far less ice than today – probably less than 50% of the minimum Arctic sea ice recorded in 2007.
But the researcher says that even with a loss of this size, the sea ice will not reach a point of no return.
“I think we can say that with the loss of 50% of the current ice, the tipping point wasn’t reached.”
The idea of an Arctic tipping point has been highlighted by many scientists in recent years. They have argued that when enough ice is lost it could cause a runaway effect with disastrous consequences.
There is no word whether the inventor of the internet and Global Warming Grand Poo-bah, Al Gore will call for the arrests of the scientists of filed the study or the ice caps themselves. After all, he stands to make billions of dollars out of the climate change hoax he will do his best to make sure this latest news will not spread. Ultimately we will not know until he returns from his latest Antarctic vacation.
