Frozen Carbon

Jonathan Corum, New York Times

This is a polar map of permafrost extent in the Northern Hemisphere. A sidebar explains how permafrost, as it forms and later thaws, serves as both a sink and source for carbon to the atmosphere. Related multimedia is a slideshow of permafrost scientists from U. of Alaska, Fairbanks, collecting permafrost data in the field.

Teaching Tips

  • Use with National Snow and Ice Data Center (NSIDC) website for much more extensive information on permafrost.

About the Science

  • This polar map shows the extent of permafrost in the Northern Hemisphere as well as the sea ice extent in September 2011.
  • Map units are percent area of permanently frozen ground.
  • Comments from expert scientist: Visually very pleasing. Requires further context. It is suggested to combine this resource with others to give a fuller picture.

About the Pedagogy

  • Polar view maps are always useful in countering the distortions of the common US-centric maps.
  • Brief text, illustrations, and photos of scientists help make the importance of permafrost clearer and more interesting to those in more southern latitudes.

Technical Details/Ease of Use

  • Since this graphic comes from the New York Times, there are some commercial elements on this webpage. The map and graphical elements of this webpage can be downloaded from a web browser. Photos of scientists appear on a different page, which has ads for movies in the sidebar.
