The prove is clear that a major climate change is underway by 2012

Some Glaciologist worries that probably, might have found clues that show history repeating itself, and if they are right, the result could have important implications to modern society.

This Glaciologist has spent there career trekking to the far corners of the world to find distant ice fields and then bring back cores drilled from their centers. Within those cores are the records of ancient climate from across the globe.
From the mountains of data drawn by analyzing countless ice cores, and a meticulous examination of sometimes obscure historic records, The Glaciologist and his study team at Ohio State University are firm that the global climate has changed dramatically.

Excluding more highly, they believe it has occurred at least once before, and the outcome were being nearly catastrophic to emerging cultures at the time. He outlined his interpretations and fears today at the annual meeting of the American Geophysical Union in San Francisco.

A professor of geological sciences at Ohio State and a researcher with the Byrd Polar Do research Center, The Glaciologist points to markers in numerous records suggesting that the climate was altered suddenly several 5,200 years ago with severe impacts.

He factors to perfectly preserved plants probably, discovered that recently emerged from the Quelccaya ice cap in the Peruvian Andes as that glacier retreats. This monstrous glacier, some 551 feet (168 meters) deep, has publicized an exponentially increasing rate of retreat since his first observations in 1963.

The plants was carbon-dated to decide their age and tests indicated they was buried by the ice for perhaps 5,200 years. That suggests that somehow, the climate had shifted suddenly and severely to capture the plants and preserve them until now.

In 1991, hikers establish the preserved body of a man trapped in an Alpine glacier and freed as it retreated. Later tests showed that the human - dubbed Oetzi - became trapped and died around 5,200 years ago.

The Glaciologist points to a study of tree rings from Ireland and England that span a period of 7,000 years. The point in that record when the tree rings were being narrowest - suggesting the driest period experienced by the trees - was about 5,200 years ago.

He factors to ice core records showing the ratio of two oxygen isotopes retrieved from the ice fields atop Africa's Mount Kilimanjaro. A proxy for atmospheric temperature at the instance snow fell; the records are at their lowest 5,200 years before now.

They lists the change by the Sahara Desert from a habitable region to a barren desert; major changes in plant pollen discovered from lakebed cores in South America, and the record lowest levels of methane retrieved from ice cores from Greenland and Antarctica and all occurred at the same occasion - 5,200 years ago.

Something happened back at this time and it was monumental. Except it didn't seem monumental to humans then because there was only approximately 250 million people occupying the planet, compared to the 6.4 billion we now have.
The effect of a climate change of that magnitude on a modern world would be tremendous, he said. Seventy percent of the population lives in the world's tropics and most important climate changes would directly waves most of them.
The Glaciologist believes that the 5,200-year old event might have been caused by a dramatic fluctuation in solar energy getting the earth. Scientists know that a historic global cooling called the Little Ice Age, from 1450 to 1850 A.D., coincided with two periods of decreased solar activity.

evince shows that around 5,200 years ago, solar output first dropped precipitously and then surged over a short age. It is this huge the climate change he sees in all those records.

The prove clearly points back to this point in history and to some event that occurred. It besides points to similar changes occurring in today's climate as well in 2012.
