Pemanasan Global Fisika Kelas 10 Kurikulum Merdeka | Pengertian, Dampak, Penyebab & Usaha Mencegah

Introduction

This tutorial provides an overview of global warming, tailored for 10th-grade physics students under the Merdeka Curriculum. It will cover the definition, causes, impacts, and ways to prevent global warming, making the content relevant and applicable in real-world contexts.

Step 1: Understand the Definition of Global Warming

• Definition: Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, particularly the emission of greenhouse gases.
• Key Points:
  • Greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
  • These gases trap heat in the atmosphere, causing the greenhouse effect.

Step 2: Identify the Causes of Global Warming

• Major Causes:
  1. Fossil Fuel Combustion: Burning coal, oil, and natural gas for energy releases significant amounts of CO2.
  2. Deforestation: Trees absorb CO2; cutting them down reduces this absorption.
  3. Agricultural Practices: Livestock production and rice cultivation emit methane.
  4. Industrial Processes: Certain manufacturing processes release greenhouse gases.

Step 3: Explore the Impacts of Global Warming

• Consequences:
  • Climate Change: Altered weather patterns can lead to extreme weather events.
  • Melting Ice Caps: Increased temperatures cause glaciers and polar ice to melt, raising sea levels.
  • Ecosystem Disruption: Many species face extinction due to habitat changes.
  • Health Risks: Increased heat can lead to health issues like heatstroke and respiratory problems.

Step 4: Discuss Efforts to Prevent Global Warming

• Preventive Measures:
  1. Reduce Fossil Fuel Usage: Switch to renewable energy sources like solar, wind, and hydro.
  2. Enhance Energy Efficiency: Use energy-efficient appliances and improve building insulation.
  3. Promote Reforestation: Planting trees can help absorb CO2 from the atmosphere.
  4. Encourage Sustainable Agriculture: Practices like crop rotation and organic farming can reduce emissions.

Step 5: Engage in Community Awareness and Action

• Community Initiatives:
  • Organize local clean-up events to reduce waste.
  • Advocate for policies that support renewable energy and conservation efforts.
  • Educate peers about the importance of global warming and how they can contribute to solutions.

Conclusion

Understanding global warming is crucial for students as they prepare to face environmental challenges. By recognizing its causes, impacts, and prevention strategies, students can actively participate in creating a sustainable future. Next steps include exploring local environmental initiatives and considering personal actions to reduce their carbon footprint.
