Global Warming

Learn about the gradual increase in Earth's temperature caused by man-made and natural factors like greenhouse gas emissions from cars, factories, and animals. Discover how carbon dioxide, methane, and CFCs contribute to global warming and its effects, such as rising sea levels, extreme weather, and disease spread. Take action by conserving energy, driving less, and switching to cleaner energy sources to combat this urgent environmental issue.

Presentation Transcript

  1. Global Warming

  2. What is global warming? • Global warming is the gradual increase of the Earth’s average temperature. • It has been an issue for over 500 years.

  3. What causes it? • Man made and natural causes that increase greenhouse gases • Exhaust gases from cars • Exhaust gases from factories • Methane gas from animals • Methane gas released when a tundra melts

  4. Which Greenhouse Gases? • Carbon dioxide is the largest contributor. It comes from burning fossil fuels and exhaust from cars. • Methane from cows, rice growing and mining. • CFCs from air conditioning units, refrigeration applications and aerosol propellants.

  5. How does it effect us? • Increase in Earth’s surface temperature • Hotter summers and warmer winters • Rise in the Earth’s sea level • More floods and impact to fresh water supply • Crop production • May increase in the U.S. • May decrease in other less developed countries • The spread of disease • Warmer wetter weather could increase the spread of infectious diseases carried by insects

  6. What can we do about it? • Find cleaner more efficient forms of energy • Conserve energy • carpooling, recycling, drive more fuel efficient cars • Plant trees

  7. What else can we do about it? • Drive 100 fewer miles per week and fly 3000 fewer miles per year. • Turn the thermostat down by 2 degrees in the winter. • Replace 10 incandescent light bulbs with compact fluorescents.

  8. Summary Unless people take action to solve global warming it may seriously impact life on Earth.
