Humans Cause Global Warming
Global Warming Debate
Today we are debating the important topic of global warming. As the affirmative team, we strongly believe that global warming is caused by the actions of humans. But this is not just a belief, this is a fact. Global warming, by definition, is a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. The greenhouse effect is the trapping of the sun 's warmth in a planet 's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet 's surface. In simpler terms, this means that the pollution emitted from the earth, such as the gasses from factories, cars etc. enter the atmosphere and the co2 from these gases absorb the heat from the sun and intern warms the climate.
The pollution or carbon dioxide enter the Earth 's atmosphere and absorb heat from the sun, heating the environment, therefore an increase in co2 means an increase in heat, this resulting in bigger problem for global warming. The main producer of this pollution and greenhouse gases are ofcourse humans, our environment and climate are the ones that have to pay for the humanly actions causing global warming. Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. These gases such as carbon dioxide (co2) accummulate in the atmosphere and trap heat that normally would exit into outer space. The main source of excess greenhouse gases is the human use of fossil fuels. The burning of fossil fuels to generate energy for example driving cars, using electricity from coal-fired power plants, or heating homes with oil or natural gas, humans release carbon dioxide and other heat-trapping gases into the atmosphere. Over 100 years ago the co2 level was 35% less
