2. INTRODUCTION
•Global warming means the
rise in Earth’s average
temperature over time.
•It is caused mainly by human
activities.
•It affects climate, environment,
and life on our planet.

3. CAUSES OF GLOBAL WARMING
•Burning of fossil fuels (coal, oil,
gas).
•Deforestation.
•Industrial emissions.
•Vehicle pollution.
•Overuse of electricity and
energy.

4. GREENHOUSE EFFECT
•Greenhouse gases trap heat in the
Earth’s atmosphere.
•Main gases: CO₂, CH₄(methane),
N₂O, and water vapour.
•This natural effect becomes harmful
when gases increase.

5. EVIDENCE OF GLOBAL WARMING
•Melting glaciers and polar ice
caps.
•Rising sea levels.
•Changing rainfall patterns.
•Increasing global temperatures.

6. EFFECT ON ENVIRONMENT
•Extreme weather events (floods,
droughts, cyclones).
•Loss of wildlife habitats.
•Coral reef destruction.
•Forest fires and biodiversity loss

7. EFFECTS ON HUMANS
•Health problems (heat strokes,
diseases).
•Food and water shortages.
•Migration and displacement.
•Economic losses due to disasters.

8. STEPS TO REDUCE GLOBAL WARMING
•Steps to Reduce Global
Warming
•Use renewable energy (solar,
wind).
•Plant more trees.
•Reduce, reuse, and recycle.
•Save electricity and water.
•Avoid plastic and pollution.

9. ROLE OF INDIVIDUALS
•Use public transport or cycle.
•Conserve energy at home.
•Spread awareness in
community.
•Support eco-friendly
products.

10. CONCLUSION
•Global warming is a serious
threat to our planet.
•Every small step makes a big
difference.
•Together, we can protect our
Earth for future generations.
•“The Earth is not ours; it’s a
treasure we hold in trust.”
