Study seeks abrupt climate change clues
FRISCO — Icebergs may have been drifting off the coast of Florida as recently as 21,000 years ago, university researchers said after developing a climate model that recreates ocean currents from the end of the last ice age.
The study implies that the mechanisms of abrupt climate change are more complex than previously thought, according University of Massachusetts Amherst oceanographer Alan Condron. The models are supported by the discovery of iceberg scour marks on the sea floor along the entire continental shelf.
