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

Global Warming and Greenhouse GasesThe backgrounds climate is predicted to change because human activities are altering the chemical topic of the atmosphere through the buildup of glasshouse gases primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping stead of these gases is undisputed. Although uncertainty exists about exactly how earths climate responds to these gases, planetary temperatures are rising. Go to the Emissions section for oftentimes 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 clean 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 earth s 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 change magnitude nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have travel by about 15%. These increases have enhanced the heat-trapping capability of the earths atmosphere. Sulfate aerosols, a...
