I need help from the readers to determine if 2010 will finish ahead or below 2005 – the red line in the DMI graph.
2010 is currently tracking just below 2005, but note there was a downwards dip in mid-September, 2005. What caused this?
The PIPS video below shows what happened in September, 2005.
In mid-September, strong winds started blowing off the East Siberian and Laptev Seas, which compressed the ice towards the North Pole. This caused the dip seen in the DMI graph.
The images below show the current date in 2005 and 2010 respectively. Note that 2005 had a lot of thin/low concentration ice in the Laptev/Kara Seas which was vulnerable to being blown around by the wind in September. The ice is less extensive, but thicker in that region in 2010.
What do you think? Will 2010 beat 2005? Please explain your reasoning.
