What is Global Warming?.
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 powers the earth's weather and climate it also heats the surface of the earth. According to John Houghton, Co-Chairman of the Scientific Assessment of Climate Change, "the basic principle of global warming can be understood by considering the radiation energy from the sun which warms the Earth's surface and the thermal radiation from the Earth and the atmosphere which is radiated out to space" (Houghton, 12).
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.
