Study Notes

Climate Change

  • Climate change is a shift in global or regional patterns, largely due to rising atmospheric carbon dioxide from fossil fuel use.
  • Associated with a rise in global average temperatures, also known as global warming.
  • Human activities (open burning, fossil fuel emission, vehicle emissions, CFC gases) produce excess long-lived greenhouse gases that trap heat, unlike water vapor.
  • Greenhouse gases include water vapor, carbon dioxide, methane, and nitrous oxide.

Effects of Climate Change

  • More frequent and severe extreme weather events (droughts, snowstorms) in temperate regions, linked to warming Arctic weather patterns.
  • Increased coral reef bleaching due to rising ocean temperatures.
  • Wildfires and reduced wildlife habitats in warmer, drier regions.

Climate Change Impacts on the Philippines

  • Intense El Niño events.
  • Rising sea surface temperatures (spikes of 4-5°C above normal can harm coral reefs and fish catch).
  • Ocean acidification, leading to widespread coral reef death.
  • Sea level rise (potential for submerging low-lying communities – 4 to 6 meters).
  • Intensified tropical cyclones.
  • Increased rainfall, river flows, and flooding.

Climate Change and Food Security

  • Reduced crop yields (estimated 25% decline).
  • Reduced fish catches (estimated 40% decline in tropical countries).
  • Impact on farmers due excessive heat and rain.
  • Increased malnutrition.

Energy Crisis

  • An energy crisis is a societal problem with diminished energy availability and increased consumer costs, arising from the limited natural resources powering industrial society.
  • Causes include: overconsumption, overpopulation, unexploited renewable energy options, poor infrastructure, delayed power plant commissioning, energy waste, poor distribution systems, major accidents & natural disasters, wars, tax hikes, strikes or geopolitical events.

Environmental Awareness and Education

  • Fosters connection to the natural world, promotes sustainable development, and encourages conservation.
  • Aims to educate future generations to handle environmental issues responsibly.
  • Key components include awareness, knowledge, concern, skills, and participation.

Benefits of Environmental Education

  • Heightens creative and critical thinking.
  • Promotes tolerance & understanding.
  • Meets state/national standards across subjects.
  • Reduces "biophobia" and "nature deficit disorder".
  • Encourages healthy living.
  • Strengthens communities.
  • Empowers students and teachers.
  • Leads to responsible action for environmental improvement.

Environmental Stewardship in Academic Service Learning

  • Promotes community linkages for nature preservation.
  • Focuses on proper waste segregation, waste reduction, reuse, and recycling.
  • Seeks to reduce energy costs in school campuses.
