Page 2: How Does Climate Change Affect Our Planet and Our Lives?
Understanding Global Warming, Greenhouse Gases, Climate Impacts and Climate Action
Climate change is one of the greatest environmental challenges facing humanity today. It refers to long-term changes in Earth's climate, including rising temperatures, changing rainfall patterns and an increase in the frequency and intensity of extreme weather events. Although Earth's climate has changed naturally over millions of years, the current rate of change is largely driven by human activities.
One of the primary causes of climate change is the increased concentration of greenhouse gases such as carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) in the atmosphere. These gases trap heat from the Sun, creating the greenhouse effect. Human activities such as burning fossil fuels, deforestation, industrial production and certain agricultural practices have significantly increased greenhouse gas emissions.
Climate change affects every region of the world. Rising global temperatures contribute to melting glaciers, rising sea levels, stronger storms, prolonged droughts, heatwaves and changing weather patterns. These changes threaten ecosystems, biodiversity, food security, water resources, public health and economic development.
The impacts of climate change are felt by both people and nature. Farmers face changing rainfall patterns, coastal communities experience increased flooding, wildlife loses natural habitats and vulnerable populations become more exposed to environmental disasters. Addressing climate change requires cooperation between governments, industries, scientists and citizens across the globe.
Understanding climate change helps learners recognize the importance of environmental responsibility and encourages sustainable actions that contribute to protecting the planet for present and future generations.

Climate Change Facts
Did You Know?
- Greenhouse gases naturally keep Earth warm, but excessive emissions intensify global warming.
- Forests act as natural carbon sinks by absorbing carbon dioxide from the atmosphere.
- Renewable energy sources produce electricity with much lower greenhouse gas emissions than fossil fuels.
- Protecting ecosystems such as forests, wetlands and oceans strengthens resilience against climate change.
Reflection Questions

Vocabulary Builder
| Word | Meaning |
|---|---|
| Climate Change | Long-term changes in Earth's climate caused by natural processes and human activities. |
| Global Warming | The gradual increase in Earth's average temperature due to greenhouse gas emissions. |
| Greenhouse Gases | Atmospheric gases such as carbon dioxide and methane that trap heat. |
| Renewable Energy | Energy generated from naturally replenished sources such as sunlight, wind and water. |
| Climate Action | Efforts taken by individuals, communities and governments to reduce climate change and adapt to its impacts. |
Conclusion
Climate change is a global challenge that requires local and international action. By reducing greenhouse gas emissions, protecting forests, conserving natural resources and adopting sustainable lifestyles, humanity can reduce climate risks and build a healthier, more resilient future. Every positive action—whether by individuals, communities or nations—helps protect our planet for generations to come.
"The choices we make today shape the climate of tomorrow. Protect the Earth, protect our future."
