Global warming is the gradual increase of temperature in Earth’s surface, oceans, and atmosphere. Some people may say that global warming is just a theory that has not been proven scientifically; however, I do believe that global warming is happening and that there is strong evidence about this occurrence. Such evidence includes the increase of carbon dioxide, the rising of sea level, the increase of acid in the ocean, and clearly, the changes in global climate. In fact, mostly all sorts of human activities cause these changes. Ninety-seven percent of climate scientists agree that human actions have changed the Earth’s atmosphere in the past two centuries (Climate.nasa.gov).

The warming of Earth’s surface begins with the greenhouse effect, which is the leading cause of global warming. The greenhouse effect is the exchange of incoming and outgoing energy emission that warms the Earth. A great example of this phenomenon given by Marc Lallanila, writer of “What is the Greenhouse Effect?” is when a car parked in a cold, sunny day. The solar radiation that is coming in warms up the inside of the car, but the solar energy that is going out is trapped inside the car’s closed windows. Greenhouse gases are the gases in the atmosphere that absorb radiation, such as water vapor, carbon dioxide, methane, and nitrous oxide. Out of all these greenhouse gases, carbon dioxide is the primary gas produced due to the combustion of fossil fuels from electricity, transportation, and industrial
