3. Absorption of infrared radiation by atmospheric gases and re-radiation of the energy back towards Earth Greenhouse Effect

4. Although it is the most common greenhouse gas, it only persists in the atmosphere for about 9 days H 2 O (Vapor)

5. This international agreement to reduce climate change was enacted in 2005, It required industrialized countries to reduces greenhouse gas emissions to 5% below their 1990 levels between 2008 and 2012 Kyoto Protocol

6. Though there is not technically a “hole”, it has been reduced by 30% over Antarctica. Ozone Depletion

7. A consequence of this process: Rising sea level due to melting glaciers and melting sea ice Global Climate Change

8. This greenhouse gas increases in the atmosphere when we have increased deforestation and fossil fuel combustion CO 2

9. Much of the radiation emitted by the earth is captured and trapped here Troposphere

10. N2ON2O

11. CFCs CH 4 N 2 O H 2 O CO 2 Greenhouse gases

12. CFCs (Chlorofluorocarbons)

13. Changes in the average weather that occurs in an area over a period of years or decades Global Climate Change

14. CH 4 (Methane) This gas is a more potent greenhouse gas than CO 2

15. Trap Earth’s heat in the troposphere which warms the atmosphere and Earth’s surface. Greenhouse gases

16. CO 2

17. This greenhouse gas readily dissolves in water and much has been absorbed by the world’s oceans. This has led to ocean acidification which causes coral bleaching and reduction of phytoplankton in oceans. Global Climate Change

18. Most photochemical smog forms here Troposphere

19. Ozone Depletion

20. Released as a result of intensive use of inorganic fertilizer, burning fossil fuels, animal waste management, and sewage treatment N2ON2O

21. This greenhouse gas absorbs more infrared radiation from Earth than any other molecle H 2 O (Vapor)

22. Anthropogenic chemicals that are made primarily of chlorine and fluorine atoms attached to a carbon backbone CFCs (Chlorofluorocarbons)

23. Greenhouse effect

24. Sources of this greenhouse gas include: Cattle flatulence Fossil fuel mining / extraction Landfills Wastewater treatment Swamps Rice cultivation (paddies) CH 4 (Methane)

25. The United States and Australia did not sign this treaty because of its potential economic impact and it did not require developing countries such as China and India to reduce greenhouse gas emissions Kyoto Protocol

26. Anthropogenic sources include: Burning fossil fuels Agricultural practices Deforestation Landfills Industrial production of new chemicals Greenhouse gases

27. This substance has the greatest greenhouse warming potential because it is nonreactive in the troposphere and insoluble in water (so it isn’t washed out of the atmosphere with rain). It can catalyze the removal of an oxygen atom from ozone over and over again. CFCs (Chlorofluorocarbons)

28. Consequences of this phenomenon include: Loss of Biodiversity Melting permafrost Increase in severe / extreme weather Changes in ocean currents Changes in vegetation zones Rise in sea level Global Climate Change

29. Global climate change is of great concern here since this is where weather events occur Troposphere

30. Natural product from the complete combustion of hydrocarbons (fossil fuels) CO 2

31.  Though it is naturally occurring, this greenhouse gas can persist in the upper atmosphere for about 100 years until it is destroyed. It is 300 time more powerful than CO 2. N2ON2O
