Climate and Greenhouse Gases

“Unless someone like you cares a whole awful lot nothing is going to get better it's not”

What is Climate?

Climate refers to the long-term weather patterns in a particular area. It is different from weather, which changes daily.

Climate Over Time

In the past, Earth's climate changed due to natural events like volcanic eruptions and ice ages.

Today, human activities are causing rapid climate change.

Burning Fossil Fuels – Coal, oil, and natural gas release large amounts of CO₂ into the atmosphere.

Agriculture – Livestock and fertilizers contribute to methane (CH₄) and nitrous oxide (N₂O) emissions.

Deforestation – Cutting down trees reduces the Earth's ability to absorb carbon dioxide.

Waste Production – Landfills emit methane as organic waste decomposes.

Industrial Processes – Factories release greenhouse gases from chemical reactions and energy

Urbanization – Expanding cities lead to more energy consumption and pollution.

Greenhouse Gases and Their Impact

Have you ever been inside a greenhouse What did it feel like?

Greenhouse Gases and Their Impact

What Are Greenhouse Gases (GHGs)? Gases that trap heat in the Earth's atmosphere, causing global warming

Major Greenhouse Gases

+77.6%

Carbon Dioxide (CO₂) – from burning fossil fuels.

16.3%

Methane (CH₄) – from agriculture and waste.

6.1%

Nitrous Oxide (N₂O) – from fertilizers and industries.

How Have Greenhouse Gas Levels Changed?

GHG levels were stable for thousands of years but have increased dramatically since the Industrial Revolution. This increase has led to rising global temperatures, extreme weather, and melting ice caps.

What Can We Do?

Track Our Carbon Footprint!

What is a Carbon Footprint?

Definition: The total amount of greenhouse gases we produce through daily activities.

Key Sources

Why it matters: More emissions = more climate change impacts.

Visual content is a cross-cutting, universal language, like music. We are capable of understanding images from millions of years ago, even from other cultures.
