State of Flux: Images of Change
http://climate.nasa.gov/stateOfFlux/index.cfm

NASA Climate, NASA

This collection of photos from the NASA Climate website features images related to global change. Not all images show change caused directly by climate change and energy use, and descriptive captions indicate causes for change in most of the images.

Teaching Tips

  • It is crucial to emphasize that these changes depicted on this site may or may not be due to or attributable to human activities and climate change.
  • Search website by using CTR+F and type in your search term in the box.

About the Science

  • Images include changes related to climate change directly (e.g. glaciers melting) and indirectly (e.g. pine bark beetle infestations), as well as consequences of energy development/use (e.g. Chernobyl 2011 and damming the Nile for hydroelectricity).
  • It must be emphasized that images of global change are not always due to or attributable to human induced climate change.
  • For example, Sea Saw images of Caspian Sea from week of June 30, 2011 show changes that are due to human activities– specifically irrigation diversions of streams into the Caspian Sea for growing cotton– but not directly related to climate change (although the changes did impact human health and altered weather patterns in the region).
  • Comments from expert scientist: The striking visual imagery effectively communicates earth surface changes. The changes themselves are compelling. Imagery from different instruments and missions is being (at least visually) set to a similar reflectance scale, in order to allow for visual decadal comparisons.

About the Pedagogy

  • These images can help show dramatic, fairly large-scale changes over relatively short time scales, but it is important for viewers not to jump to conclusions about the cause or attribution of the change.

Technical Details/Ease of Use

  • The images are easy to access with links to other images of change.
