This video shows some of the most dramatic fluctuations to our cryosphere in recent years, using visuals created with a variety of satellite-based data.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Video could be stopped along the way to have discussion about the graphs embedded in the video. Use NASA NEO website to get current data.
Educator might want to be aware of positive feedback loop mechanisms to facilitate further discussion.
This video and its accompanying text ([link http://svs.gsfc.nasa.gov/vis/a000000/a003600/a003619/]) demonstrates how, using satellite observations, scientists can monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.
Passed initial science review - expert science review pending.
Draft of script is provided for students to follow along. Though some of data references are dated, overall trends in different geographic areas continue in the same direction.
Graphics are good.
