Teaching Materials
Positives
- This article covers a wide range of topics, such as tipping points and feedback loops, while remaining brief and concise.
- The included chart helps students visualize the history of Earth's climate.
Prerequisites
- Students may become overwhelmed or distressed when discussing climate tipping points. Teachers may want to follow this article with a solutions-based discussion to instill hope for the future.
- Students should have a basic understanding of climate change and the greenhouse effect.
Differentiation & Implementation
- Teachers can use this article to introduce climate feedback loops and their significance. After reading the article students can select one of the loops mentioned to research more in-depth.
- Teachers can follow this article with the video 10 Years to Transform the Future or Threaten the Planet to further discuss climate tipping points and the urgent need for action.
- After reading this article, teachers can focus on the final paragraph to transition students into talking about solutions. Teachers can task students with selecting a solution from Project Drawdown's Table of Solutions and creating a persuasive piece of writing to urge those with power to implement it.
This resource explores both the man-made and natural sources of climate change. It explains how the climate system changed millions of years ago and how greenhouse gasses have fueled the current global warming that we are all seeing. The hothouse trajectory theory, feedback loops, tipping points and the future climate we might anticipate if immediate action is not made to buck the trend are also highlighted. This resource is suggested for use in instruction after passing our science review.
