Global Warming and the Greenhouse Effect
In the science fair project, which I am going to be performing, has to do with global warming and the greenhouse effect. The definition of global warming is increase in the earth’s temperature caused primarily by increased emissions of several gases into the atmosphere particularly carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20), ozone (O3), water vapor (H20). When these gases are trapping heat, they cause greenhouse effect. The definition of greenhouse effect is the role the atmosphere plays in insulating and warming the earth’s surface. The problem that I have run into during study is to know is global warming will affect the world greatly on the environment or is it nothing to worry about. I am also concerned about the gases that are released and cause the global warming do indeed cause danger to the earth. I have been dealing with this problem for quite sometime now and I am glad I have the chance to find out though experimentation. My hypothesis is that when global warming takes place, the temperature will rise. Scientists believe that global warming causes icecaps to melt and they say that if the icecaps melt that we will face dramatic climate changes, flooding, and islands disappearing from rising in the ocean level. In my experiment, my dependent variable, or the variable that is to be affected during the experiment, is the temperature. These will both be affected by the independent variables which are time and weather. No one has control over time and weather, that is why they are the independent variables and they also affect the outcome of the experiment. The atmosphere is not transparent, that is why the earth warms up. Since there are not as many trees and things to absorb the carbon dioxide, the temperature rises and humidity also rises.
