Scientists conducting ice core drilling in North Greenland were recently shocked to recover a core sample from two miles below the surface that contained blades of grass and pine needles. So what's the big deal about finding grass and pine needles under two miles of ice? Can't we find grass and pine needles all over the place? The big deal is that present day theories about how the Ice Age took place describe it as a slow process that took thousands of years, meaning that when ice slowly formed over the land, there's no way there would have been pine needles and blades of grass still thriving. What this core sample reveals, however, is that the ice sheet must have formed very quickly

Can the OP supply who the scientists were and out of what university they're doing their research?

Also, consider that just this past July of 2004, plant material consisting of probable grass or pine needles and bark was discovered at the bottom of the Greenland ice sheet under about 10,400 feet of ice. Although thought to be several million years old, Dorthe Dahl-Jensen, a professor at the University of Copenhagen's Niels Bohr Institute and NGRIP project leader noted that the such plant material found under about 10,400 feet of ice indicates the Greenland Ice Sheet "formed very fast."38 Beyond the obvious fact that such types of organic material suggest an extremely rapid climactic change and burial by ice, the question is, Why hasn't such organic material been stripped completely off Greenland by now by the flowing ice sheets? For instance, we know how fast these ice sheets move - up to 100 meters per year in central regions and up to 10 miles per year for several of Greenland's major glaciers. Given several hundred thousand to over a few million years of such scrubbing by moving ice sheets, how could significant amounts of such organic material remain on the surface of Greenland?
