Ellesmere Island National Park in Canada. Ohio State University researchers and their colleagues have discovered the remains of a mummified forest that lived on the island 2 to 8 million years ago, when the Arctic was cooling.
Over the summer of 2010, the researchers retrieved samples from broken tree trunks, branches, roots, and even leaves -- all perfectly preserved -- from Ellesmere Island National Park in Canada.
"Mummified forests aren't so uncommon, but what makes this one unique is that it's so far north. When the climate began to cool 11 million years ago, these plants would have been the first to feel the effects," Barker said. "And because the trees' organic material is preserved, we can get a high-resolution view of how quickly the climate changed and how the plants responded to that change."
Analysis of the remains has only just begun, but will include chemical and DNA testing.
One downside to finding the trees is that as the ice melts and the wood begins to rot it will release more methane and carbon into the atmosphere, possibly contributing to global warming. I suppose it depends on how many more forests they find as the the ice melts.
Temperature and precipitation history of the Arctic
...Solar energy reached a summer maximum (9% higher than at present) ca 11 ka ago and has been decreasing since then, primarily in response to the precession of the equinoxes. The extra energy elevated early Holocene summer temperatures throughout the Arctic 1-3° C above 20th century averages, enough to completely melt many small glaciers throughout the Arctic, although the Greenland Ice Sheet was only slightly smaller than at present... As summer solar energy decreased in the second half of the Holocene, glaciers reestablished or advanced, sea ice expanded, and the flow of warm Atlantic water into the Arctic Ocean diminished. Late Holocene cooling reached its nadir during the Little Ice Age (about 1250-1850 AD), when sun-blocking volcanic eruptions and perhaps other causes added to the orbital cooling, allowing most Arctic glaciers to reach their maximum Holocene extent..."
Have another cup of Koolaid from the elite brain-washers to counteract this bit of evidence. There's a good sheeple.
Colleagues at the University of Minnesota identified the wood from the deposit, and pollen analysis at a commercial laboratory in Calgary, Alberta revealed that the trees lived approximately 2 to 8 million years ago, during the Neogene Period. The pollen came from only a handful of plant species, which suggests that Arctic biodiversity had begun to suffer during that time as well.
The team is now working to identify other mummified plants at the site, scanning the remains under microscopes to uncover any possible seeds or insect remains.
i can never understand why people can turn a good conversation into basically the actions of a 5 year old. your better than thou actions only makes you look like the fool. you are the sheeple more so than the o.p. for the reason of your actions and words. imo

please dont rise to the bait...when you bring yourself down to his level u lose the high ground...let him be content in his bashing...not only will others lose respect for him regarding his non-needed statement but he will soon realise ON HIS OWN that his actions get him absolutely nowhere.

What I am curious about is that if they found perfectly preserved leaves, then the "freeze" must have been very quick as leaves decompose rather quickly.
Interesting indeed and I can't wait to find out what if any their results of this study shows.
Geologically how old are these trees? Isotopic geological data for the Black Forest Bed equal 209–214 million years old. The trees in Crystal Forest, Rainbow Forest, and Blue Mesa Forest are older but we have no isotopic data for those deposits.
Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone") is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree having turned completely into stone by the process of permineralization. All the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three dimensional representation of the original organic material. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen which inhibits aerobic decomposition. Mineral-laden water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay, a stone mould forms in its place. In general, wood takes fewer than 100 years to petrify. The organic matter needs to become petrified before it decomposes completely.[1] A forest where the wood has petrified becomes known as a petrified forest.

The game has been lost because of the WILLFUL ignorance of people like the person who just posted this thread. I have every right to be very angry for someone who is contributing to the misery and death of others while acting like they have the moral high ground.

The lumber industry is salivating... this may be the only untouched forest in this part of the hemisphere. I can only imagine the treasures hidden under the ice.

Because you know me so well!
So start your own thread on that issue, but please don't come into mine and derail the conversation from what I wanted to share with people. Please?
