Teaching Tips

  • Educators could also use images alone with slider tool, without the text, or could paraphrase or simplify text.
  • CLEAN resource Arctic Sea Ice 2012 is a video that addresses Arctic sea ice extent over a similar time period.

About the Content

  • The amount of sea ice loss over the past 28 years is quite dramatic.
  • Accompanying background information discuss how the data was collected and explains the loss of ice extent as a positive (self-reinforcing) feedback mechanism.
  • At the time of this review (2016), the summer of 2012 still holds the record for minimum sea ice in the Arctic. But that may change. Up-to-date information on sea ice can be found on the Arctic Sea Ice News page of the NSIDC.
  • Comments from expert scientist: The development of Arctic sea ice is an important topic. The sea ice extent minimum of 2012 is presented in a clear manner that is easy to understand, but also conveys its importance.

About the Pedagogy

  • Quite a bit of informational text accompanies the graphic.
  • Further resources for exploration are hyperlinked in the text.

Technical Details/Ease of Use

  • Slider is easy to use; images are clear.
