Introduction
Anthropogenic Global Warming
Many consider global warming to be the largest threat that faces the earth today. This is just the opposite as we could not survive without global warming! The topic for this speech will be whether or not there is an imminent threat of Anthropogenic (or manmade global warming) at the end of my speech I would like the audience to develop the truce perspective on the issues of manmade global warming. This will be done through a small representation of the facts related to manmade global warming. To have a better understanding of what we’re exactly talking about in regards to the manmade global warming we will look at this chart. (See chart) The atmosphere is divided into four parts, 78% is in

What causes people to oppose anthropogenic global warming?
The premise for anthropogenic global warming on the surface appears to be a plausible one. Humans through their need for fossil fuels take CO2 from underground and release it into the atmosphere where the sun’s ray’s heat the CO2 gases and generate more heat, the more CO2 we put into the atmosphere, the more the planet warms up. The fact is if we add up all of the manmade CO2 gases the percentages are quite small. We can see this percentage in the chart below as 1.0% of manmade contribution to global warming. With the greatest effect on the earth’s climate contributed to water vapor at 95%.
