Abrupt end of the last interglacial s.s. in north-east France
Close study of past interglacials might indicate how and when the present interglacial will end and whether the limit is heading towards a warming or a cooling. No certain prediction has been possible because of man's interference with the environment. But it is reported that when exploring the...
