Global Warming and Greenhouse Gases Essay -- Climate Change, Greenhous

Global Warming and Greenhouse GasesThe lands climate is predicted to change because human activities are altering the chemical part of the atmosphere through the buildup of glasshouse gases primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping attribute of these gases is undisputed. Although uncertainty exists about exactly how earths climate responds to these gases, orbicular temperatures are rising. Go to the Emissions section for ofttimes more on greenhouse gases.Energy from the sun drives the earths weather and climate, and heats the earths surface in turn, the earth radiates energy back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat slenderly like the glass panels of a greenhouse.Without this natural greenhouse effect, temperatures would be much lower than they are now, and life as known today would non be possible. Instead, thanks to greenhouse gases, the earths average temperature is a more hospitable 60F. However, problems may arise when the atmospheric engrossment of greenhouse gases increases.Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increase nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have locomote by about 15%. These increases have enhanced the heat-trapping capability of the earths atmosphere. Sulfate aerosols, a...
