Arctic was ice free in the Holocene, and guess what! The polar bears survived!
The Norwegian Geological Survey in a press statement of 20 October 2008 said there was "less ice in the Arctic Ocean 6000-7000 years ago". The Norwegian research team of Dr Astrid Lysa and Dr Elliv Larsen in a study of beach ridges on the northern shore of Greenland found important evidence which showed that the Arctic was ice free during the first Holocene warming! "the climate in the northern regions has never been milder since the last ice age than it was about 6000-7000 years ago" said Dr Astrid Lysa. Professor Ian Plimer Professor of Geology at the University of Adelaide in his classic book "Heaven and Earth" also notes that the first global warming during the Holocene ,between 9000 and 65000 BC was the warmest the earth has been since the end of the last big ice age. Did the polar bears starve and disappear? Of course not! If they had then there would be no polar bears today as they are not migratory! Instead a report in the International Business Times of 2 August 2011 noted that the number of polar bears is at an historic high!
