The first few slides show how greenhouse gases got their name; which are the greenhouse gases, their sources, their levels over time. Slide 15 onwards describes possible non-anthropogenic causes of global forming. Slide 20 onwards show how the greenhouse gases are removed from the atmosphere both by nature and how they could be removed by man-made technologies. Slides 22-27 relate to how temperatures and CO2 levels are measured as they existed thousands of years ago; other slides show how sea levels are measured and their effects if they continue to rise. The next few slides show how the skeptics and the pro environmental groups try to prove they are correct(slide #35 should actually be #34).  Slide 35 onwards presents the arguments of people who go to the extreme of saying global warming could be good for you(really only for some). Slide 43 onwards gives my take on the issue, including the immediate deleterious effects of unchecked use of fossil fuels.
