An international team of scientists have discovered evidence in the geological formations in a coastal cave showing that more than three million years ago – a time in which the Earth was two to three degrees warmer than the pre-industrial era – sea level was as much as 16 meters higher than the present day. Their findings have significant implications for understanding and predicting the pace of current-day sea level rise amid a warming climate.
The scientists from the University of South Florida, University of New Mexico, Universitat de les Illes Balears and Columbia University published their findings in today’s edition of the journal Nature. The analysis of deposits from Artà Cave on the island of Mallorca in the western Mediterranean Sea, serves as a target for future studies of ice sheet stability, ice sheet model calibrations and projections of future sea level rise, the scientists said.
“We can use knowledge gained from past warm periods to tune ice sheet models that are then used to predict future ice sheet response to current global warming,” said USF Department of Geosciences Professor Bogdan Onac.
