Why the Arctic Is Climate Change's Canary in the Coal Mine

  • This video and article explains how melting ice and warming temperatures in the Arctic are often an early indicator for impacts elsewhere. 
  • Students will learn about positive and negative feedback loops, the albedo effect, and what melting ice in the Arctic means for the global climate. 
Teaching Tips


  • The animated video is engaging and easy to understand.
  • The interactive questions reinforce key ideas and are a great way for students to independently check their understanding. 

Additional Prerequisites

  • An ad plays before the video.
  • A TED-Ed account is needed to access the interactive questions and use the discussion feature; accounts are free but students must be 13 or older to register. 


  • Science classes could use this resource as a introduction to reflectivity, feedback loops, the albedo effect, equilibrium, or homeostasis. 
  • As an extension activity, have students research examples of other feedback loops that impact climate change and present their findings. 
  • Other related resources include this lesson on feedback loops, this article about feedback loops fueling wildfires, and this video about how a warmer Arctic will intensify global warming.
Scientist Notes
The Arctic is warming faster than any other place on the globe. As such, it is seeing a larger increase in extreme weather events. This resource from TED-Ed discusses some feedback loops that affect the Arctic. This resource is recommended for teaching.
