Scientists To Drill Record-Breaking Ice Core
Scientists To Drill Record-Breaking Ice Core
“The truth, always the truth–at all costs”
I will strive to give you perspectives on the news that you will rarely receive from other sources. At times, there will be eye-witness reports from troubled areas, at other times, there will be documentary,interviews and other interesting works.
I am committed to providing information by posting/archiving videos, articles, and links. I also investigate to raise awareness on numerous issues, inspire critical thinking, involvement, and hopefully to help make our world a better place for all.
According to a recently published report, the report states It’s been called the Holy Grail – earth’s oldest ice-core, reaching back more than 1.3 million years.
Over the next few years, scientists are aiming to drill the record-breaking ice-core in East Antarctica, to better understand the role of carbon dioxide in triggering the Earth’s regular Ice Ages.
The research comes amidst new concern that the West Antarctic Ice Sheet is at the point of rapid collapse, committing the world over the next few hundred years to more than three metres of sea level rise.

MAJOR CLIMATE CHANGE OCCURRED 5,200 YEARS AGO: EVIDENCE SUGGESTS THAT HISTORY COULD REPEAT ITSELF
COLUMBUS, Ohio — Glaciologist Lonnie Thompson worries that he may have found clues that show history repeating itself, and if he is right, the result could have important implications to modern society.
Thompson has spent his career trekking to the far corners of the world to find remote 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 review of sometimes obscure historic records, Thompson and his research team at Ohio State University are convinced that the global climate has changed dramatically.
But more importantly, they believe it has happened at least once before, and the results were 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 Research Center, Thompson points to markers in numerous records suggesting that the climate was altered suddenly some 5,200 years ago with severe impacts.
Evidence shows that around 5,200 years ago, solar output first dropped precipitously and then surged over a short period. It is this huge solar energy oscillation that Thompson believes may have triggered the climate change he sees in all those records.
He points to perfectly preserved plants he 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 shown an exponentially increasing rate of retreat since his first observations in 1963.
The plants were carbon-dated to determine their age and tests indicated they had been 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.
……………………………..Thompson believes that the 5,200-year old event may have been caused by a dramatic fluctuation in solar energy reaching 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.
Evidence shows that around 5,200 years ago, solar output first dropped precipitously and then surged over a short period. It is this huge solar energy oscillation that Thompson believes may have triggered the climate change he sees in all those records.
“The climate system is remarkably sensitive to natural variability,” he said. “It’s likely that it is equally sensitive to effects brought on by human activity, changes like increased greenhouse gases, altered land-use policies and fossil-fuel dependence.
“Any prudent person would agree that we don’t yet understand the complexities with the climate system and, since we don’t, we should be extremely cautious in how much we ‘tweak’ the system,” he said.
“The evidence is clear that a major climate change is underway.”

1000′s of people are now under the impression that the ICE CORES show no severe or rapid change in climate….that’s a real shame…because the evidence shows exactly the opposite…..:(
