Grade Discipline Core Idea
9-12 ESS2.D: Weather and climate

The role of radiation from the sun and its interactions with the atmosphere, ocean, and land are the foundation for the global climate system. Global climate models are used to predict future changes, including changes influenced by human behavior and natural factors.
9-12 ESS3.D: Global climate change

Global climate models used to predict changes continue to be improved, although discoveries about the global climate system are ongoing and continually needed.
