climate change
Jump To Navigation
Definition

changes in the measures of Earth’s climate over a long period of time including weather, precipitation, and temperature patterns

Use In A Sentence

Rising global temperatures due to climate change are causing more frequent and intense extreme weather events, such as hurricanes and heatwaves.

fossil fuel
Jump To Navigation
Definition

Natural carbon-rich fuels that are formed over long periods of time and release greenhouse gases when burned.

Use In A Sentence

Since 1750, the burning of fossil fuels has added more and more carbon dioxide to the atmosphere, rapidly warming the planet and causing climate change.

greenhouse gases
Jump To Navigation
Definition

Gases, such as carbon dioxide, that trap heat and keep the planet warm. These are found naturally in our atmosphere, but human activity—especially burning fossil fuels—has added more and is causing climate change.

Use In A Sentence

Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, trap heat from the Sun inside Earth’s atmosphere.

parts per million (ppm)
Jump To Navigation
Definition

A unit of measurement used to express very small concentrations of a substance within a larger mixture, often used for measuring gases like carbon dioxide (CO₂) in the atmosphere.

Use In A Sentence

In June 2023, the concentration of carbon dioxide (CO₂) in Earth’s atmosphere reached 424 parts per million (ppm).

temperature anomaly
Jump To Navigation
Definition

A way of measuring the increase or decrease in temperature in relation to a baseline average.

Use In A Sentence

The trend is even more apparent when we overlay global temperature anomaly alongside sea-level rise.

Understanding Climate Change

Driving Question: What is climate change?

There’s no simple definition for climate change. But to overcome it, we have to understand it. Explore what climate change is, and think about how it impacts you—and the entire world.

Learning Objectives:

  1. Define climate change.
  2. Explain the main causes of climate change.
  3. Analyze historical data and trends that demonstrate climate change over time.
  4. Apply claim-testing skills to evaluate data and people’s perceptions about climate change.
STEP 1

Opener: Understanding Climate Change

What do you know about climate change? Develop your own definition and perspective.

STEP 2

What Do We Mean When We Talk About Climate Change?

Teaching Tools

Heads up: You can turn on captions, slow down the speed of the video, and have students follow along by reading the video transcript. For more video tips, check out the OER Project Video Guide External link .

Climate change has been around for 4.5 billion years. What’s so special about it now? Watch the video to explore what’s different about today’s climate change, then come up with a working definition of the term as you work through the activity.

What Is Climate Change? External link

We won the planetary lottery. But based on current trends, we have to wonder: Will our luck run out?
STEP 3

Parts Per Million

Teaching Tools
Look at you staying sharp. We got you a gift External link . Just a little thanks for all you do for your students.

The numbers tell a story—but is it the right one?

STEP 4

Fact or Fiction?

Teaching Tools

Claim testing is OER Project’s approach for assessing the quality and veracity of claims—an essential skill when building digital literacy. This is the first of many claim-testing activities that appear throughout the course.

Are they liars or just uninformed? People are getting way too good at presenting opinion as fact. Luckily, claim testers help us get to the bottom of just about anything.

STEP 5

The Climate Pioneer

Teaching Tools

Did you know Eunice Foote was the first to describe the greenhouse effect? (Spoiler: A male scientist got the credit.) Graphic bios like these bring overlooked and forgotten stories to light.

Learn more about Eunice Foote and her impact on our understanding of climate change in this blog post External link . 

Meet the scientific pioneer who was the first to describe the greenhouse effect. Did she get the credit she deserves?

STEP 6

The Evidence of Climate Change

Teaching Tools

Don’t forget: You can find key ideas and sample answers to these materials—and all articles, videos, and activities—in the Lesson Guide External link found at the top of the page. 

How do we know climate change is happening? Dive into the charts in the article to find the evidence, then put the claims to the test in the activity that follows.

STEP 8

Closer: Understanding Climate Change

It’s time to make a claim—but be prepared to defend it.
