The ice sheet that covers the northernmost reaches of our planet has expanded and shrunk over the past 2 million years — but it was thought that Greenland’s bitter cold and miles-deep ice had been a more or less constant feature.
However, new evidence has suggested it was once a much warmer and greener place than we are used to today. What it took in the past to melt the ice and cover it with plants could be critical for predicting how the Arctic will respond to climate change in the present day.
A long-lost core of earth drilled up from beneath mile-thick ice in northwestern Greenland in the 1960s has shown that in the past 1 million years — and perhaps as recently as 400,000 years ago — it was once home to a vegetated landscape.
Scientists had expected to find sand and rock in the dirt but were instead surprised to see twigs and leaves.
Yup. “Lost” for 60 or 70 years. Pretty good illustration of how our nation’s perpetual concern over science, research, providing historic discoveries to institutions of education and knowledge…when we’re condemning other nations…in practice, is OK when it’s OUR MILITARY that’s aiding the research.
Even by accident.
