Antarctic Sea Ice Extent Sep 22 2014 – 1,488,000 sq km above Normal

Antarctic Sea Ice Extent Sep 22 2014 – 1,488,000 sq km above the 1981-2010 mean. Data for Day 264. Data here.

Extent has also taken a downwards turn (as has Area). There will be no “10th all-time record in 10 days” this year (unless it gets really weird).

But 2014 will hold the record for most days over 20 million because 2014 is the only year it has ever happened.

  1. “But 2014 will hold the record for most days over 20 million since 2014 is the only year it has ever happened.”

    This sentence is confusing because “since 2014” can mean “the time period from 2014 to now”. I suggest replace “since” with “because”.

    Sea ice extent (or area) is widely used as a leading indicator of anthropogenic global warming because temperatures in the polar regions were expect to be more responsive to human-caused greenhouse gas emissions (due to the very low humidity) than in other regions. Sea ice area is sensitive to sea surface temperature. The increase in Antarctic sea ice is a major indictment of climate models. The CMIP5 multi-model mean annual southern sea ice area (RCP45) hindcasts a decline of 9.7% from 1980 to 2014. Cryosphere Today shows the year-to-date Antarctic sea ice area increased by 24.4% from 1980 to 2014.

    The global sea ice annual average area has been increasing for 3 years, and is well above the 1970 to 2008 average. A graph of the monthly and annual average is:
