Arctic sea ice levels reach seasonal low

Arctic sea ice extent has dropped to a seasonal low and the sixth lowest level since the beginning of its 35-year satellite record, according to the National Snow and Ice Data Centre.

The ice extent is about 5 million square kilometres, and despite being above the level observed the same time last year, long term trends are predicting a seasonally ice free Arctic Ocean by the middle of the century

Anthropogenic climate change and natural variability are resulting in the long-term decline in sea ice cover and thickness, with the Arctic warming nearly twice as fast as the rest of the globe.

    In 2007, the BBC reported climate scientists predictions that the Arctic would definitely be ice free by 2013.

    It's 2013 and the Arctic is not ice free.

    They were wrong..

      It's well on the way to being ice free Gerard (JetA1fuel).

      I am sure your track record in business forecasting is no more impressive.

      The trend is clear: the Arctic will likely be ice free in the summer before too many years pass.

      40% decline in ice area over three decades?
      Linear extrapolation -> 100% decline in ice area over 7.5 decades.

      75% decline in ice volume over three decades.
      Linear extrapolation ->100% decline in ice volume over 4 decades.

      The above data can be combined to give 58% decline in average ice thickness in three decades, from which linear extrapolation ->100% decline in ice thickness over 5-and-a-little-bit decades.

      Take your choice.

      Thanks Mark, I see the video is dated 2008.

      Perhaps they've learned a bit since then?

      2013 was the most extreme figure quoted by one scientist amongst many that they quote in that particular article...

      They also quoted other scientists saying:
      - "2040 to 2100",
      - "It might not be as early as 2013 but it will be soon, much earlier than 2040."
      - "My thinking on this is that 2030 is not an unreasonable date to be thinking of."

      "They" were not wrong. One of the scientists they quoted was.
