• Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants
• The earth’s atmosphere acts like a greenhouse to capture the sun’s heat, allowing for the emergence of life forms, including humans
• Global warming is like a greenhouse with high-efficiency reflective glass installed the wrong way around, trapping too much heat inside
• The temperature of the earth is rising faster than at any previous time in history due to the excess heat being trapped
• Since the Industrial Revolution, the global annual temperature has increased by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit
• Deforestation:

  • Forests are being depleted for domestic and commercial purposes
  • This leads to an environmental imbalance and global warming
• Use of Vehicles:

  • Even short distances result in gaseous emissions
  • Vehicles burn fossil fuels emitting carbon dioxide and toxins, increasing temperature
• Chlorofluorocarbon:

  • Excessive use in air conditioners and refrigerators adds CFCs to the environment
  • CFCs affect the ozone layer, leading to ozone layer depletion and increased temperature
• Industrial Development:

  • Harmful emissions from factories contribute to the rapid increase in earth's temperature
• Agriculture:

  • Farming activities produce carbon dioxide and methane gas, adding to greenhouse gases and increasing earth's temperature
• Overpopulation:

  • More people lead to increased carbon dioxide levels in the atmosphere, a primary gas causing global warming
• Volcanoes:

  • Ash and smoke emitted during volcanic eruptions affect the climate and contribute to global warming
• Water Vapour:

  • A greenhouse gas that increases with the earth's temperature
  • More water evaporates due to temperature rise, adding to global warming
• Melting Permafrost:

  • Frozen soil with trapped environmental gases
  • Melting releases gases into the atmosphere, increasing Earth's temperature
• Forest Blazes:

  • Forest fires emit carbon-containing smoke, increasing earth's temperature and causing global warming
