Bogdan Onac (University of South Florida si UBB-Cluj) despre schimbarile rapide ale nivelului marii in revista Science

Bogdan Onac from University of South Florida and UBB-Cluj (Romania) is part of a team discussing novel findings about rapid sea level changes in the journal Science.

„ScienceDaily (Feb. 12, 2010) — Theories about the rates of ice accumulation and melting during the Quaternary Period — the time interval ranging from 2.6 million years ago to the present — may need to be revised, thanks to research findings published by a University of Iowa researcher and his colleagues in the Feb. 12 issue of the journal Science.”

„Something very unusual happened about 80,000 years ago, as Earth’s last ice age was getting started. Sea levels that had been dropping for thousands of years–as more and more water became trapped in expanding glaciers–suddenly rose, according to a new study. Then after a few thousand years, the levels fell again. Although the researchers haven’t found the cause of this phenomenon, they say the findings could force at least a partial rethinking of the mechanisms governing Earth’s climate.”
