NEEM, Greenland, Ice Core Data
In December of 2011 and January of 2012, I read about:
"They pulled up ice that was once falling as snow in Greenland around 150,000 years ago! Then they analyzed and read it like a climate history book." I found and contacted people who were analyzing the data and they sent me a link.
The Danish website for this NEEM data is
When I looked at this in Jan 2013, I did not find what I was looking to find. When I looked at this, October 19, 2014, I found 108 thousands of years of the NEEM data that I have been waiting for. NEEM ice core data, has been analyzed and published, covering 108 thousand years. showing that from 108 thousand years age, little snow fell in Greenland, until the modern warming.
This does support the idea that the steps in the temperature data, over the past 108 Thousand years are steps in the ice sheet advance and not new snowfall. The ice sheet was advancing and thinning. The evidence of new snowfall was found because they believed it happened and struggled to believe anything they found that would support that idea. NEEM and Vostok, page before this one, do not show the spikes in snowfall that were supposed to happen in the cold frozen time. They did not happen. Those spikes were ice advance spikes.
As the massive ice sheet advances and thins, the weight movement could promote rebound in some places, when they did not expect rebound yet, and give the false indication of large changes in ocean levels. They believed the ice volume was increasing and the oceans dropping and looked for support. They still do not understand how the ice actually advanced as it melted and thinned. The melted water was trapped and did promote increases in the advances. There were no massive new snowfalls during the long cold. There were just massive advances of the ice sheet. The oceans were cold and low, massive new snowfalls were not possible.
The snow fell in the warm time, 120 to 150 thousand years ago, much fell more in the north. It depressed the land and did keep the path for warm water to flow into the Polar region open longer so the flow into the Arctic did not stop when the ocean dropped enough to cut off flow today, after rebound. When the flow was finally cut off, the snowfall stopped and mostly stayed stopped.
NEEM has ice from 150 thousand years ago, so we know the warming was starting the snowfall. We know it ended before 108 thousand years ago because that data is in the NEEM spreadsheet. I do look forward to more analysis and publication for the data between 108 and 150 thousand years ago.
