If you are looking for teaching tools or lessons plans related to climate change then check out TROP ICSU.
The TROP ICSU project collects and curates educational resources for teachers and self-learners to learn about Climate Change. The quality of life of future generations is largely dependent on the quality of education that we impart to today’s students.
The goal is not to introduce Climate Education as a stand-alone topic, but to integrate it with the core curriculum of Science, Mathematics, and Social Sciences.
