Arctic Ice May Be The Lowest It’s Ever Been… If You Count It Right

Arctic Ice May Be The Lowest It’s Ever Been… If You Count It Right

The media are atwitter because the National Snow & Ice Data Center (NSIDC) announcedthat: “Arctic sea ice appears to have broken the 2007 record daily extent and is now the lowest in the satellite era….Arctic sea ice extent fell to 4.10 million square kilometers (1.58 million square miles) on August 26, 2012. This was 70,000 square kilometers (27,000 square miles) below the September 18, 2007 daily extent of 4.17 million square kilometers (1.61 million square miles).”

If that is true, then the world has 0.006% less ice this year than in 2007. (Source).

The NSIDC would have us believe that the satellite era began in 1979, but it actually began in 1967. Below is a graph from Steve Goddard with data from IPCC 1990 report showing that sea ice was much lower prior to 1979 which happened to be the year of largest sea ice extent since 1967. We should also note that extent of Arctic sea ice is cyclic. Setting records depends on where you start counting.
