1. Climate Change and Its Effects An Eco-Inspired Presentation with Real Data 🌍

2. Introduction • Earth's climate is warming rapidly • Human activities drive most of the change • Impacts are global — affecting nature and people

3. Main Causes • Burning fossil fuels (CO₂ emissions) • Deforestation & land use change • Agriculture & livestock (methane) • Industrial processes

4. Global Temperature Rise • Earth's surface temperature ↑ ~1.28°C since 1850s • 10 warmest years occurred since 2014 • Source: NASA, 2025

5. CO₂ Emissions Trend • Global CO₂ emissions ≈ 38.5 billion tons (2022) • Fossil fuels = main contributor • Major emitters: China, USA, India • Source: Our World in Data

6. Sea Level Rise • Global mean sea level ↑ ~91 mm since 1993 • Rising ~0.45 cm per year (NASA 2025) • Coastal flooding risk increasing

7. Environmental Effects • Glacier & ice cap melting • Ocean acidification & coral loss • Disrupted ecosystems & biodiversity decline

8. Human Impacts • Heatwaves, droughts, & floods • Food & water insecurity • Climate migration & health risks

9. Solutions & Mitigation • Shift to renewable energy • Protect & restore forests • Improve energy efficiency • Global cooperation & climate policy

10. India & Tamil Nadu Focus • Rising temperatures & coastal vulnerability • Chennai at risk from sea level rise (~78 cm by 2100) • Need for green infrastructure & adaptation

11. Conclusion • Climate change is real — and urgent • Every action counts 🌿 “There is no Planet B.”
