Arctic Sea Ice Extent: In October 2008, Fastest Ever Growth
As expected a few days ago: October 2008 has seen the fastest Arctic sea ice extent growth ever recorded. According to the data published by IARC-JAXA, the amount of growth has reached 3,481,575 square kilometers for the month, or 112,319 sq km per day on average.
The previous maximum was October 2007, with 3,330,937 sq km for the month and 107,450 sq km per day on average. Record shrinkage remains July 2007, with 2,913,593 sq km lost and 93,987 sq km per day on average.
Growth should be starting levelling off now. November values could be as high as 2,179,844 sq km (2002) or as low as 964,688 sq km (2006).
So I would make the specific prevision that 1) a seasonal cycle will show up in sea ice data and 2) due to 1) the october/november increase and the may/june decrease of seaice will become bigger and faster. I might check that with CMIP model data but I am pretty sure that this is what the model show
Here’s a link for the “CMIP model“. It never ceases to amaze me how elastic AGW theory truly is.
