Since the beginning of time there have been documented variations in climate and temperature. A well known climate variability that Californians experience, El Nino, occurs every three to six years and results in warmer ocean temperature, increased ocean upwelling, and drier winters. While this phenomenon appears to be threatening to our environment, it is simply just a natural climate cycle. However there is a hazardous threat to our Earth that has been occurring for the past hundred years. The phenomenon known as global warming refers to the average increase in the Earth’s overall temperature. Such an increase in temperature can result in drastic climate changes that in tern can lead to a rise in sea level, changes in rainfall, and detrimental impacts on plant and wildlife. In order to truly understand the phenomenon that is global warming one must analyze and understand the greenhouse effect, greenhouse gases, and climate change.

The Earth’s atmosphere plays a key role in the global warming process. As the sun’s energy p

Global warming will lead to an increase in global temperature, rise in sea level, change in rainfall, and many other climate occurrences. With the continued emission of greenhouses gases, like carbon dioxide, methane, and nitrous oxide the threat of global warming becomes more prevalent. The atmosphere cannot bear the continued increase in pollutants and eventually the earth’s human, plant, and wildlife will suffer. Global warming is in fact a real threat and action must be taken to protect the environment.

When the earth radiates such energy back to space, atmospheric gases trap departing energy. Atmospheric gases like water vapor, carbon dioxide, and others gases simulate the glass panels of greenhouse. Therefore these chemicals are known as the greenhouse gases. The greenhouse effect is responsible for the insulation on the earth thus making human, wildlife, and plant life possible. While the natural process of the greenhouse effect is necessary, problems occur when the atmospheric concentration of greenhouses gases increases.
