Global Warming 2


Like the glass in a greenhouse, certain gases that occur naturally in the atmosphere tend to trap the sun's heat. This natural "greenhouse effect" helps keep the Earth's average temperature at a comfortable 59° Fahrenheit. Without these greenhouse gases, the Earth would
be about 0° F, like a deep- frozen snowball.
The earth's climate is predicted to change because human's are changing the chemical composition of the atmosphere by the buildup of greenhouse gases—which mostly is carbon dioxide, methane, and nitrous oxide. These gases trap heat which is well known. But it is

Energy from ...

These increases have made the heat-trapping worse in the earth's atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space, but, sulfates do not live long in the atmosphere.


Why are greenhouse gas concentrations increasing? Most scientists believe that the burning of fossil fuels and other human's doings is the main reason for the increased rate of carbon dioxide. What has changed in the last few hundred years is the constante release of carbon dioxide by human's. Energy burned to run cars and trucks, heat homes and businesses, and power factories is one of the main reasons for about 80% of todays carbon dioxide problem, about 25% of U.S. methane emissions, and about 20% of ...
