2013 Arctic ice maximum: 10 straight years of declining sea ice peak

NASA providing the video: the above is an interesting fact. The maximum extent of the Arctic sea ice was the “sixth smallest” recorded in 35 years of satellite observation.

As you watch the video you can see some amazing images:

  • An August 2012 cyclone helped break up the sea ice, sending a large pack into warmer southern waters
  • Ice north of Alaska was subject to fracturing, with cracks in the ice “hundreds of miles long” – most likely due to thinner sea ice

Each year, the sea ice maximum gets smaller, this year it reached its maximum of 15.13 square kilometers on March 15. As the National Snow and Ice Data Centre notes, the ten lowest maximums have occurred in the last ten years:

Arctic sea ice reached its maximum extent for the year on March 15 at 15.13 million square kilometers (5.84 million square miles). This year’s maximum ice extent was the sixth lowest in the satellite record (the lowest maximum extent occurred in 2011). The ten lowest maximums in the satellite record have occurred in the last ten years (2004 to 2013).

Such data puts to rest the “temperatures have plateaued” nonsense. You can see the 2013 maximum against the 1979-2000 median:

Such data puts to rest the “temperatures have plateaued” nonsense.
