Arctic Sea Ice Extent

p.1384 'Holocene fluctuations in Arctic sea-ice cover'

According to this recent paper there have been times when Arctic sea-ice cover was less extensive than at the end of the 20th century. So much for that supposedly “record low” in 2007 when, as it happens, Antarctic sea-ice was at a record high. In fact, the sea-ice area at the poles is still at the 30 year mean (link below).

“A peer-reviewed paper published in the Canadian Journal of Earth Sciences finds that Arctic sea ice extent at the end of the 20th century was more extensive than most of the past 9000 years. The paper also finds that Arctic sea ice extent was on a declining trend over the past 9000 years, but recovered beginning sometime over the past 1000 years and has been relatively stable and extensive since.”
