Lecture Notes: Addressing Global Warming

Introduction

• Global warming is a critical issue affecting our planet.
• Significant environmental damage includes:
  • 50% of global forests removed
  • 375 billion tons of CO2 emissions since industrialization

Causes of Global Warming

• Greenhouse Effect: Primary cause
  • Atmospheric gases trap heat, allowing sunlight in but preventing heat from escaping
• Human Activities:
  • Burning of fossil fuels
  • Pollution from plastics
  • Deforestation

Impact on Vulnerable Nations

• The Philippines:
  • Ranked among the most climate-vulnerable nations
  • Experiences extreme weather events and rising sea levels

Potential Solutions to Global Warming

• Energy Solutions:
  • Switch from fossil fuels to renewable energy (no harmful gas emissions)
  • Reduce electricity usage to decrease fossil fuel dependency
• Sustainable Practices:
  • Practice the "Six Rs" to manage waste and reduce emissions
• Conservation Efforts:
  • Plant trees to enhance natural atmospheric exchange (photosynthesis)
  • Raise awareness and share information about global warming

Role of the Philippines in Climate Change

• Ground zero for experiencing climate change
• Local stories need international support

Call to Action

• Acknowledge the gravity of the problem
• Collective action can lead to environmental improvements
• Emphasize that Earth does not belong to us; we belong to Earth
• Humans are both the problem and the solution

Conclusion

• It's not too late to take action
• Working together can make a significant difference in saving our planet

Key Takeaway

• The lecture emphasizes the importance of addressing climate change through both individual and collective actions.
• Highlight the need for sustainable practices and renewable energy to mitigate global warming effects.
