There are several scientific organisations that keep an eye on the Arctic sea ice cover and put out graphs to inform us of the amount of ice that is left. You can see most, if not all, of them on the ASI Graphs webpage. I expect the record on most of these graphs to be broken in weeks to come.
Larry Hamilton's graph:
Here are the numbers of all the minimums since 2005:
- 2005: 4.09 million square km
- 2006: 4.03 million square km
- 2007: 2.92 million square km
- 2008: 3.00 million square km
- 2009: 3.42 million square km
- 2010: 3.07 million square km
- 2011: 2.90 million square km
- 2012: 2.88 million square km (and running)
As usual, Jim Pettit has the details:
Though it happened 23 days earlier than it did last year, today's CT SIA value is already 27,281 km2 lower than last year's record (which itself only edged out the 2007 record by fewer than 15k km2). 17 days elapsed last year between the date the 3 million km2 mark was passed and the record was set; this year, that only took four days.
Over the course of the record--1979-2011--the average CT area loss from this day to minimum has been 521k km2. Based on a straight extrapolation from prior years, 2012 SIA would/could/almost certaionly will end up somewhere between 1.92 million and 2.77 million km2, with a mean minimum of 2.36 million km2.
Tomorrow DMI sea ice extent?
