Feedback Loops - Introduction

Positives

• This video provides an informative introduction to feedback loops that is easy to understand for many ages.
• The video uses metaphors and visuals to support understanding.
• Students will learn that there is still time to take action against climate change; however, if humans take no action the Earth will reach a tipping point after which it will be nearly impossible to reverse the damage to Earth's systems.

Additional Prerequisites

• Feedback loops are a more advanced topic in climate science, so students should already have an understanding of climate change and its main causes and effects.
• The concept of chain reactions, feedback loops, and tipping points can be abstract and difficult for students to grasp. Consider discussing these terms before viewing the video and providing some simple examples to aid understanding. 
  

Differentiation

• After watching, teachers could ask students the following questions:
  • What would happen if everyone in the world stopped using fossil fuels tomorrow?
  • Would global warming stop right away if fossil fuels disappeared? Why or why not? 
• Although this video ends on a hopeful note, it has a relatively urgent tone that can be upsetting for students. Teachers should plan to provide support and options for students to take action for the climate so they do not feel powerless.
• After watching this introduction, dive deeper into this topic by watching this video about feedback loops and sea ice or this lab about feedback loops and albedo.
