2012 Time Series Of Arctic Ice Extent January 1 -- September 14, 2012
Prof Peter Wadhams of Cambridge University calls for "urgent" consideration of new ideas to reduce global temperatures.
"This collapse, I predicted would occur in 2015-16 at which time the summer Arctic (August to September) would become ice-free. The final collapse towards that state is now happening and will probably be complete by those dates".
The sea ice in the Arctic Ocean dropped below the previous all-time record set in 2007. This year also marks the first time that there has been less than 4 million square kilometers (1.54 million square miles) of sea ice since satellite observations began in 1979.
This animation shows the 2012 time-series of ice extent using sea ice concentration data from the DMSP SSMI/S satellite sensor. The black area represents the daily average (median) sea ice extent over the 1979-2000 time period. Layered over top of that are the daily satellite measurements from January 1 -- September 14, 2012.
A rapid melt begins in July, whereby the 2012 ice extents fall far below the historical average. The National Snow and Ice Data Center (www.nsidc.org) will confirm the final minimum ice extent data and area once the melt stabilizes, usually in mid-September.
