6. Ozone hole over Antarctica, September 2006. The blue and purple colors are where there is the least ozone. Ozone depletion is human caused – due to the release of Chlorine and Bromine gases into the Stratosphere.

9. All weather takes place in the Troposphere Shortwave radiation comes through the atmosphere Earth warms and radiates longwave radiation

10. All weather takes place in the Troposphere Shortwave radiation comes through the atmosphere Earth warms and radiates longwave radiation

11. The average atmospheric temperature varies year by year, but overall, there has been a noticeable increase since 1920. From book: Essentials of Geology, S. Marshak, p. 533

12. Carbon is always on the move From book: Essentials of Geology, S. Marshak, p. 520

14. Plants use Carbon Dioxide and sunlight to grow. The byproduct of Photosynthesis is Oxygen and sugars that make the plant grow. Image from: grapevine.net.au/.../ science/photosynthesis.html

17. There is 30 percent more Carbon today than there was 150 years ago

18. Carbon in the atmosphere joins with Oxygen to form CO 2 Carbon atom Oxygen atoms

19. Image from IPCC Present-day Greenhouse Gas Sources 56.6% Carbon Dioxide, fossil fuels (oil, coal) 7.9% Nitrous Oxide 17.3% Carbon Dioxide, decay of plant material 14.3% Methane, natural gas, agriculture, etc.

21. All weather takes place in the Troposphere Shortwave radiation comes through the atmosphere Earth warms and radiates longwave radiation, heat is trapped
