1. The current causes of climate change: the human causes

2. Difference GLOBAL WARMING is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere. CLIMATE CHANGE is a broader term that refers to long-term changes in climate, including average temperature and precipitation.

3. How Global Warming Works Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )

4. How is global warming measured?

5. Ice Core Data CO 2 Measurements Before 1958 - Antarctica

6. CO 2 Atmospheric Measurements CO 2 Measurements Since 1958 – Mauna Loa, Hawaii

7. The main greenhouse gases

9. Explanation of the causes of global warming

10. Temperature (Northern Hemisphere) CO 2 Concentrations 1000 Years of CO 2 and Global Warming Degree Celsius Increase Parts Per Million Year 100012001400160018002000 100012001400160018002000

11. Burning of Fossil Fuels Pollution from coal, natural gas, and oil

12. Global Atmospheric Concentration of CO 2

14. Methane 24 times more potent than carbon dioxide Rising incomes and increase population have led to an increased rearing of livestock- account for about 20% of emissions Also comes from marshland, rice landfills (rotting vegetable matter), burning vegetation
