Many geological discoveries suggest that our planet was once much warmer than it is now. We have read of Arctic dinosaur fossils, camel fossils in Canada, pollen from tropical trees in Antarctica and a fossilised tropical forest in Norway, to name just a few examples.
A new study shows frozen rivers beneath Greenland’s ice sheets.
Now, a study showing that a frozen river 1,600 kilometres or 1,000 miles long to be flowing under Greenland’s ice sheet has just been pronounced at the annual meeting of the American Geophysical Union (AGU). "Christopher Chambers, a researcher at Hokkaido University in Sapporo, Japan. Chambers and his colleagues created simulations to explore the valley at different depths and model how water might melt from the surface of a glacier to the depths below — perhaps creating a flowing river, Chambers said. He presented their findings on Dec. 9 here at the annual meeting of the American Geophysical Union (AGU).
