Unit 1: Introduction to Climate Change

Climate change—the evidence of it and the news about it—surround us on a daily basis. How can we effectively evaluate information about climate change to more fully understand the causes, impacts, and solutions?

Lesson 1.1

Understanding Climate Change
There’s no simple definition for climate change, but a shared understanding is crucial to addressing it. Exploring what climate change means is the first step to addressing it.

Lesson 1.2

Climate Disagreement
If the scientific community agrees that climate change is real, why do some people deny it? Investigate why there’s so much disagreement about climate change.

Lesson 1.3

The Case for Climate Optimism
When all the news about climate change is doom and despair, is there any reason for hope? Examine different perspectives to determine if optimism is justified.

Lesson 1.4

International Climate Goals
Can international priorities and policies help—or hinder—climate action? Evaluate what’s worked and what hasn’t to think about a better path forward.
