Antarctic Sea Ice Extent Breaks All-Time Record
According to National Snow & Ice Data Center, Antarctic sea ice extent reached its all time record high on 14th September, increasing to 19.512 million sq km, and beating last year’s record high of 19.477. Records started to be kept in 1979.
This year’s record is 941,000 sq km above the long term mean, and continues an upward trend in recent years.
Extent has declined slightly in the last two days, so it may have now reached its maximum for this year.
Let’s just recall what the IPCC are saying about Antarctic sea ice in the draft of the next report.
‘Most models simulate a small decreasing trend in Antarctic sea ice extent, in contrast to the small increasing trend in observations… There is low confidence in the scientific understanding of the small observed increase in Antarctic sea ice extent.’
